Abstract
Experiential learning methods for leadership development have grown in popularity, but empirical research to support design, implementation, and ongoing evaluation has not kept pace with the demand for these programs. Problem-based learning (PBL) and action learning (AL) are two examples of these interventions used for developing agile practitioners while solving challenges found in the workplace. Addressing the complexity of these approaches, this article presents a framework that integrates PBL and AL design features to facilitate research into these similar interventions for management and leadership development. The PBL and AL literatures are compared to reveal analogous characteristics and to highlight gaps in research. The integrative framework is applied to make recommendations for human resource development practitioners conducting program evaluations.
Designing and delivering leadership development programs are among the central functions of human resource development (HRD) practitioners (Ardichvili, och Dag, & Manderscheid, 2016; Waddill, Banks, & Marsh, 2010). Fulfilling these responsibilities means attention to both leadership development, the interpersonal processes among organization members, and leader development, the intrapersonal factors that affect individual effectiveness as a leader (Day, Fleenor, Atwater, Sturm, & McKee, 2014). As such, it is recommended that HRD practitioners design leadership development programs that can address the complex individual and social aspects of leader and leadership development (Day, 2000; Day et al., 2014). Among the key leadership development trends recently identified for HRD practitioners is the use of experience-based programs (Ardichvili et al., 2016). It is commonly said that companies are shifting their leadership development resources away from formal training events toward a “70-20-10 model” that situates the majority of learning activities in work-based, experiential interventions (O’Leonard & Loew, 2012). Experiential leadership development initiatives are cited as an essential part of leadership development (Allio, 2005; Amagoh, 2009; Dalakoura, 2010), and they seem to be particularly well suited for developing the complex skills required of leaders (Hezlett, 2016).
This article focuses on one type of experiential leadership development approach, action learning (AL) and problem-based learning (PBL), which has grown in popularity within the last few decades and is used in organizations and higher education programs around the world (Anderson & Coleman, 2015; Leonard & Lang, 2010; Marquardt & Banks, 2010; Waddill et al., 2010). According to Amagoh (2009), “Action learning is a vital component of most leadership development programs, and constitutes one of the core leadership development methods at best-practice organizations” (p. 996). Experiential pedagogical techniques like AL and PBL often are described as more effective than traditional classroom-based approaches for developing leaders and practitioners (Brownell & Jameson, 2004; Johnson & Spicer, 2006; Leonard & Lang, 2010; Tushman, Fenollosa, McGrath, O’Reilly, & Kleinbaum, 2007). Overuse of conventional didactic methods such as lecturing and teacher-centered instruction consistently tops critics’ lists of reasons why institutions have failed to develop the teamwork, leadership, and problem-solving skills necessary for managers to be successful in the 21st century (Brotheridge & Long, 2007; Feldman, 2005; Gosling & Mintzberg, 2006; Roglio & Light, 2009; Samuelson, 2006).
However, these approaches face the same criticism as other leadership development programs: Although it is assumed that they have a positive impact, their processes and outcomes have not been rigorously examined to provide evidence-based guidance for designing and continuously improving leadership development programs (Allio, 2005; Amagoh, 2009; Garavan, O’Brien, & Watson, 2015; Mehrabani & Mohamad, 2015). Despite their popularity, they lack sufficient models for evaluation (Cho & Egan, 2009; Edmonstone, 2015; Hezlett, 2016). Demonstrating the impact of experience-based leadership development programs requires a framework that facilitates design, measurement, and evaluation to answer questions about which techniques and conditions work to achieve specific learning outcomes, and why (Allio, 2005; Hezlett, 2016; Hung, 2011). As summarized by Waddill et al. (2010),
Although various research accounts have placed the business-wide return on investment from action learning as anywhere from 5 to 25 times its cost, there is little empirical research or evidence on why and how action learning works. A future challenge for action learning, therefore, is to quantify the results of action learning. This will earn action learning a place at the research table and further assert its credibility to the academic community. (p. 276)
Purpose
The purpose of this article is to propose an integrative framework that can be used to help fill this gap in our understanding of AL and PBL program design effectiveness and promote evaluation studies that can provide stronger evidence for these designs when used for leadership development. Although AL and PBL are implemented in a variety of ways, typically both refer to an approach to learning that uses an ill-structured, real-life problem or opportunity that initiates the learning process, a team working together to learn while solving the problem, learner-directed action toward problem resolution, reflection on learning experiences, and a learning process facilitator or coach (Barrows, 1980; Hmelo-Silver, 2004; Hung, Jonassen, & Liu, 2008; Marquardt, 1999; Marsick & O’Neil, 1999; Revans, 1982). Drawing from prior reviews of AL and PBL (Cho & Egan, 2009, 2010; Hmelo-Silver, 2004; Hung et al., 2008; Loyens, Kirschner, & Paas, 2012; Marsick & O’Neil, 1999; O’Neil & Marsick, 2007), Table 1 presents an outline of the structure and general approaches typically followed in AL programs delivered within organizational settings and PBL programs delivered within academic settings. Although AL and PBL originated in different fields and contexts, this study will show that they are nearly identical in their core design features. By bridging the research on AL and PBL, incorporating the extensive empirical research on PBL effectiveness in medical education and the qualitative studies on AL applications in business settings, an integrative framework can advance our understanding of how these interventions can be designed for leadership development while generating a model for research and evaluation.
Steps in the Action Learning and Problem-Based Learning Processes.
The integrative framework proposed in this article specifies the essential design characteristics that can be measured to examine relationships between individual- and team-level elements and leadership development outcomes. In the next section, the steps used to search the literature for relevant sources are described, followed by a review of the theory and research behind PBL to articulate the core set of defining features for readers who are less familiar with this approach. The fourth section briefly reviews the AL literature to reveal the conceptual overlap between PBL and AL designs, leading to the proposed framework that integrates recommendations from both streams of research. The article concludes by highlighting the multilevel nature of the variables and offering recommendations for program evaluation.
Method
This research to construct an integrative framework began with an investigation into AL program design, specifically articles from scholarly and peer-reviewed sources that examined how and why AL designs are effective. Because this research focused on HRD efforts in organizations, the initial search used the EBSCOhost Business Source Premier database, which generated 389 articles from 1965 to 2012 using the search term “action learning.” Practitioner books about AL also were reviewed, and citations from articles were examined to expand the search. In addition, Web of Science was used to find articles similar to the most relevant manuscripts. Finally, additional searches of EBSCOhost Business Source Premier, Academic Search Complete, and PsycINFO were conducted between 2012 and 2016 to incorporate recently published articles relevant to the framework as it was being constructed.
The search of the AL literature confirmed conclusions from earlier reviews, which found AL research lacking in critical investigations into the key features and underlying dynamics of AL (Cho & Egan, 2009, 2010). To find additional support for AL design characteristics, the literature search was expanded to review the PBL literature, which seemed to identify many of the same design features as AL. The EBSCOhost Business Source Premier search for “problem-based learning” articles from 1965 to 2012 identified 117 articles from peer-reviewed journals. However, much of the PBL literature resides outside of business and HRD periodicals, so additional articles were collected using the reference sections of articles, books, and reviews of the PBL literature and by using Web of Science searches for similar work. PBL has been popular in both higher education and K-12 contexts, but this review focused on articles that examined PBL designs for adults and higher education. Consistent with the AL literature review, additional searches for articles in EBSCOhost Business Source Premier, Academic Search Complete, and PsycINFO were conducted between 2012 and 2016 to incorporate recently published papers relevant to this study.
PBL Background and Design
PBL Objectives and Outcomes
The origins of PBL can be traced to the medical faculty at McMaster University, who introduced problem-solving instructional techniques in the late 1960s to improve the diagnostic skills of their medical students (Barrows, 1980; Barrows & Mitchell, 1975; Hung et al., 2008; Neufeld & Barrows, 1974). Medical education programs around the world began adopting PBL as they encountered similar challenges effectively preparing physicians for clinical practice, and in the 1990s, PBL spread to other disciplines in higher education as well as K-12 settings (Hung et al., 2008). Although PBL has been used extensively in medical education, there are few published studies of its use in business or management education (Brownell & Jameson, 2004; Hallinger & Lu, 2011; Ungaretti, Thompson, Miller, & Peterson, 2015; Walker & Leary, 2009).
The objective of the McMaster faculty was to create an innovative approach to medical education that emphasized the development of capabilities and characteristics that would help students become better physicians, rather than a singular focus on teaching factual knowledge of medicine (Neufeld & Barrows, 1974). Literature reviews of PBL tend to converge around the following learning outcomes: (a) an extensive yet flexible base of knowledge, (b) problem-solving skills, (c) self-directed learning (SDL) skills, (d) intrinsic motivation to learn, and (e) collaboration skills (Hmelo-Silver, 2004; Loyens et al., 2012; Loyens, Magda, & Rikers, 2008).
Because PBL emerged as a way to develop better practitioners, the specific objectives of PBL can vary within and between programs (Barrows, 1986). For example, although developing collaboration skills was an objective of McMaster’s medical program, PBL was initially described as a technique that could be presented in a variety of formats, to individuals or to small groups (Barrows & Mitchell, 1975; Neufeld & Barrows, 1974). Barrows (1986) addressed this issue, describing PBL as a variety of educational methods with the common feature being the use of problems for instruction. Studies suggest that it supports the development of SDL strategies and skills required for complex problem solving in professional practice (Barrows, 1980, 1986; Hmelo & Lin, 2000; Hung et al., 2008). Applied to management development, PBL has been described as a powerful approach to simultaneously teach transferable critical thinking skills and domain-specific content, allowing learners to achieve both the cognitive and behavioral development necessary to solve complex problems (Brownell & Jameson, 2004; Kek & Huijser, 2011; Ungaretti et al., 2015). Furthermore, it may be an effective technique for developing tacit knowledge, or knowledge that is difficult to explain to others, derived from experience, and associated with higher levels of job performance and career success (Armstrong & Mahmud, 2008; Raelin, 2007, 2008). PBL interventions can provide contextualized learning opportunities where participants can practice activities and methods to solve problems experienced in the workplace (Hung et al., 2008). With complex, ill-structured problems serving as the catalyst for learning, PBL provides opportunities for participants to apply their knowledge in new situations, see how they deal with ambiguity, and learn skills that will help them navigate through uncertainty (Hmelo & Lin, 2000; Hung, 2011).
A thorough review of the literature examining PBL’s effectiveness in achieving these learning objectives is beyond the scope of this article, but several highlights are worth noting. First, research suggests that PBL improves a variety of professional skills, including social, critical thinking, and problem-solving skills (Hmelo-Silver, 2004; Hung et al., 2008; Loyens et al., 2012; Schmidt, Rotgans, & Yew, 2011; Schmidt, van der Molen, te Winkel, & Wijnen, 2009). Second, several meta-analyses reveal mixed support for PBL (Gijbels, Dochy, den Bossche, & Segers, 2005; Schmidt et al., 2009; Strobel & van Barneveld, 2009; Walker & Leary, 2009), and reviews of empirical studies echo these conflicting findings (Hmelo-Silver, 2004; Hung et al., 2008; Loyens et al., 2012; Mamede, Schmidt, & Norman, 2006; Schmidt & Moust, 2000; Schmidt et al., 2011; Svinicki, 2007). Taken as a whole, this literature suggests that PBL can foster long-term retention of knowledge and practical application of knowledge. However, there are many challenges associated with PBL research, including inconsistencies in PBL design (e.g., problem types) and implementation (e.g., facilitation techniques), a lack of reporting about how PBL was designed or implemented, and widely varying measures of design and outcome variables (Hung, 2011). Although most of these studies are situated in medical education, those that have examined the effectiveness of PBL in business and management education provide encouraging results (Hallinger & Lu, 2011; Walker & Leary, 2009). The next section begins with a review of research on the basic design features of PBL before elaborating on the specific design and implementation characteristics.
Defining Features of the PBL Process
Prior research suggests that five features distinguish PBL from other experiential learning techniques: (a) starting the process with the problem, (b) requiring SDL throughout the process, (c) reflection about the problem solving and learning, (d) small group collaboration, and (e) facilitation to guide learning (Barrows, 1980; Hmelo-Silver, 2004; Hung et al., 2008; Schmidt et al., 2011). Following is a review of each feature and the theories used to explain why they are critical for achieving PBL objectives.
A primary differentiating feature of PBL (and AL) compared with other types of experiential learning designs is that PBL begins with the introduction of a problem for learners to solve prior to offering any instruction about the topic (Barrows, 1980; Hmelo-Silver, 2004; Hung et al., 2008; Schmidt et al., 2011). The content to be learned is organized around the problem as students define it and formulate ideas about possible solutions. Introducing clinical problems first in the instructional process was a significant innovation for medical educators because it challenged the “sequence myth” that basic science needed to be learned before clinical science (Neufeld & Barrows, 1974). The theoretical rationale is that the problem motivates learners and becomes the focus of student-directed learning activities about the topic (Barrows & Mitchell, 1975; Hmelo-Silver, 2004; Hung, 2009; Loyens et al., 2008; Schmidt, 1983; Schmidt et al., 2011). Consistent with constructivist theories suggesting that people learn new knowledge more effectively when they can connect it with what they already know, starting with the problem is believed to activate existing knowledge schemas to help learners process new information (Hmelo-Silver, Duncan, & Chinn, 2007; Norman & Schmidt, 1992; Schmidt, 1993; Schmidt & Moust, 2000; Schmidt et al., 2011). PBL assumes that participants bring a variety of experiences and baseline knowledge into the problem-solving process, so they can identify their unique learning needs and goals based on what they know and do not know to solve the problem.
This leads to a second distinguishing feature of PBL, the emphasis on SDL (Barrows, 1986; Hmelo-Silver, 2004; Loyens et al., 2008; Schmidt et al., 2011). Although experienced facilitators guide learning as needed, participants are given the authority and time to pursue their own learning goals. Boredom, fatigue, and retention of factual knowledge were among the concerns that medical educators were trying to address with PBL (Barrows & Mitchell, 1975; Hung et al., 2008). Some PBL research suggests that SDL is an important feature because it may activate intrinsic motivation compared with passive, didactic teaching methods, and the sense of ownership and responsibility for learning may raise participant engagement in the inquiry process, fostering deep learning (Hmelo & Lin, 2000; Loyens et al., 2008; Schmidt et al., 2009). Another reason why SDL is an important part of the process is because improving students’ SDL skills is typically one of the learning objectives of PBL (Barrows, 1986; Hmelo-Silver, 2004). Building SDL skills is particularly important for physicians and practitioners who need to continually update and maintain their skills beyond school and to be effective problem solvers (Barrows, 1986; Barrows & Mitchell, 1975; Hmelo & Lin, 2000; Miflin, Campbell, & Price, 2000). For organization leaders faced with continuously shifting industry demands and complex business challenges, the ability to take control of their own learning is a critical leadership competency (Nesbit, 2012). However, if participants are poor self-regulated learners, they may struggle with PBL and require additional support (Hmelo-Silver, 2004; Miflin et al., 2000).
Reflection is a required part of PBL because it is a mechanism by which participants construct their flexible knowledge base. Reflection facilitates sense making, and it helps learners connect their PBL actions (and reactions) to their individual learning goals and metacognitive skill development (Hmelo-Silver, 2004; Pease & Kuhn, 2011; Wirkala & Kuhn, 2011). As described by Brownell and Jameson (2004), affective learning (e.g., self-monitoring, understanding others, appreciating individual differences) results from what they call the interpretive learning process whereby learners explore their values and beliefs, make comparisons with others, and develop insights about themselves from interactions. As such, reflection is an important feature that must be present throughout PBL. Because reflection is itself a cognitive skill that individuals can perform to varying degrees, a variety of techniques are recommended to support both individual and group reflection, including using structured learning journals, diaries, and facilitation (Hmelo-Silver, 2004).
Small group collaboration is a key feature noted by most, but not all, PBL scholars (Barrows, 1986; Dolmans & Schmidt, 2006; Hmelo-Silver, 2004; Loyens et al., 2012; Norman & Schmidt, 1992; Schmidt, 1993; Schmidt et al., 2011). To the extent that improving collaboration and interpersonal skills is an objective of PBL, problem solving in teams clearly would be essential to provide students opportunities for practice. However, many authors argue that team learning is essential for PBL because group discussions motivate participants to share prior knowledge, question and challenge their colleagues’ understanding of the problem, and elaborate on the shared knowledge, which is believed to optimize learning and transfer (Dolmans & Schmidt, 2006; Innes, 2006; Schmidt, 1983, 1993; Schmidt et al., 2011; van Blankenstein, Dolmans, van der Vleuten, & Schmidt, 2011). Group members also can play a scaffolding role by supporting each other as they solve problems, allowing less experienced learners to practice new skills with coaching from their more experienced peers (Hmelo-Silver et al., 2007; Reiser, 2004). Learners who have different levels of prior knowledge and expertise can observe and interact to foster understanding and sense making. Hmelo-Silver’s (2004) review of the literature supports the role of group collaboration in promoting intrinsic motivation and knowledge construction, but she also noted that differences in group dynamics and facilitation may influence the degree of collaboration and thus lead to inconsistent findings about whether PBL can develop better collaborators. Some studies comparing individual- and team-based PBL designs do not support the notion that social interaction and collaborative learning are the primary drivers of engagement, thus underscoring the need to further examine the relative impact of small group collaboration on various outcomes (Pease & Kuhn, 2011; Wirkala & Kuhn, 2011).
Finally, experienced facilitators play an important role in the learning process because PBL is not unguided discovery learning (Hmelo-Silver et al., 2007; Hung, 2009; Schmidt, Loyens, van Gog, & Paas, 2007). Participants must have the freedom to reason and learn without a directive facilitator, but careful PBL design, coaching, and scaffolding to support individual learning are required to achieve the learning objectives (Hmelo & Lin, 2000; Schmidt et al., 2011). Facilitators are used in a variety of ways to support PBL, which will be discussed in the “Integrative Framework for PBL and AL” section of this article.
To summarize, PBL features a group of learners collaborating to solve a problem while engaging in reflection and SDL under the guidance of a facilitator. The design of PBL can change to adjust features that will meet the needs of participants and the objectives and constraints of the organization. However, such flexibility is a liability for researchers wishing to evaluate PBL or understand which features influence the desired results. Before elaborating on these issues, the next section provides a comparison of PBL and AL design features.
AL Background and Design
AL Objectives and Outcomes
Unlike PBL’s origins in medical education, AL was first applied in practical business contexts by Reg Revans, who in the 1940s and 1950s began using AL within organizations to solve business problems while developing employees (Anderson & Coleman, 2015; Marquardt, 1999; O’Neil & Marsick, 2007). Revans attempted to introduce AL to academic institutions in Europe, but it has not been widely adopted in management education (Johnson & Spicer, 2006; Pedler, Burgoyne, & Brook, 2005; Raelin, 1997a, 2009). In a review of the top 50 U.S. business schools, Navarro (2008) found that only a small number of these schools required multidisciplinary experiential exercises as a required component of their curriculum. Brook and Milner (2014) reported a recent increase in the use of AL in postgraduate business education programs within the United Kingdom, and a few studies have reported successful implementations in academic settings (Bannan-Ritland, 2001; Johnson & Spicer, 2006). Research points to a variety of institutional and logistical reasons why management educators have been slow to adopt these approaches, including administrative, design, and implementation challenges (Brook & Milner, 2014; Johnson & Spicer, 2006; Raelin, 2009). However, as noted in the introduction to this article, AL is widely used within organizations around the world (Anderson & Coleman, 2015; Leonard & Lang, 2010; Marquardt, 2011).
As with PBL, the objectives of AL include helping participants develop knowledge, problem-solving skills, collaboration skills, and skills necessary for continuous learning, or “learning how to learn” (Leonard & Lang, 2010; Marquardt, 1999; Marsick & O’Neil, 1999; Raelin & Coghlan, 2006). Because AL originated in organization development contexts and is most frequently implemented in workplaces, an additional objective noted by authors is that AL can be used to advance learning, change and knowledge sharing within the organizational system (Marquardt, 1999; Marquardt & Banks, 2010; Volz-Peacock, Carson, & Marquardt, 2016; Yeo & Nation, 2010). However, this objective is not always applicable in leadership development programs, especially when AL is delivered in academic contexts (Bannan-Ritland, 2001; Johnson & Spicer, 2006). The flexible application of AL to address a variety of learning objectives and the philosophy used to implement AL can result in different AL types, but the primary focus is typically individual development (Cho & Egan, 2010; Marsick & O’Neil, 1999; Raelin, 2008).
There are fewer quantitative studies of AL compared with PBL research, and most empirical articles about AL use descriptive, case study approaches (Anderson & Coleman, 2015; Cho & Egan, 2009; Johnson & Spicer, 2006). Reviews of the research suggest that AL improves a variety of leadership skills, including collaboration, conflict management, self-awareness, coaching, communication, and continual learning skills (Cho & Egan, 2009; Leonard & Lang, 2010; Leonard & Marquardt, 2009; Raudenbush & Marquardt, 2008; Volz-Peacock et al., 2016). Studies also suggest that AL improves motivation to learn and learning transfer because it uses real work problems (Leonard & Lang, 2010; Raelin, 2007; Raelin & Coghlan, 2006; Volz-Peacock et al., 2016). However, these results also share the same set of challenges found in PBL research, which is that not all AL designs and implementations are the same. Overall, this review found far fewer quantitative studies of AL design effectiveness compared with the research on PBL design in medical education.
Defining Features of the AL Process
Similar to PBL, a variety of experiential learning programs have been called AL, making a clearly defined single method elusive, but as described by Cho and Egan (2009), “The real value of AL that differentiates it from other action strategies is a pragmatic focus on learning for the sake of problem solving” (p. 435). The “classical principles” of AL often are referenced to distinguish it from other experiential approaches, but many authors have espoused variations in these principles and subcategories of AL that make it particularly difficult to define (Johnson, 1998; Marquardt, 1999; Marquardt & Banks, 2010; Marsick & O’Neil, 1999; O’Neil & Marsick, 2007; Pedler et al., 2005; Smith & O’Neil, 2003). But, at its core, AL is practiced when a small group of learners collaborate to support individual learning through problem solving that centers around an authentic work problem, under the guidance of an adviser or coach (Marquardt, 1999; Marsick & O’Neil, 1999; Pedler et al., 2005; Revans, 1982; Smith & O’Neil, 2003). Thus, the defining features of AL are identical to PBL.
A comparison between the five PBL design features described in the previous section and commonly prescribed components of AL can further highlight the conceptual overlap. First, AL typically begins with an ill-structured problem, rather than problems delivered around predetermined curriculum or formal instruction (Leonard & Lang, 2010; Marquardt, 1999; Yeo & Nation, 2010). Second, participants are expected to take self-directed action to learn and solve the problem by asking questions to clarify and define the problem, establishing learning goals, identifying their knowledge gaps and organizational constraints, and reflecting upon possible solutions (Leonard & Lang, 2010; Marquardt, 1999; Raelin & Coghlan, 2006). The AL process should be iterative, with problem analysis, self-study, reflection, and action toward problem solving occurring until a solution is implemented and the participants receive feedback about their actions and solutions (Johnson & Spicer, 2006; Yeo & Nation, 2010). Third, reflection is a key feature of the AL process, with individual and group reflection exercises used to help learners make sense of their experiences (Leonard & Lang, 2010; Raelin & Coghlan, 2006; Raelin & Raelin, 2006; Sofo, Yeo, & Villafañe, 2010; Yeo & Nation, 2010). Fourth, participants work in small groups to engage in problem solving and learning (Leonard & Lang, 2010; Marquardt, 1999; Marsick & O’Neil, 1999). The processes and activities used within groups can vary across AL interventions, as they do with PBL, depending on the design and facilitation provided. And finally, an experienced facilitator or coach guides the group members through the learning process, serving as a model for questioning and reflection (Marquardt, 1999; Volz-Peacock et al., 2016). As with PBL, the role of the facilitator depends on the underlying school of thought in which the AL design is grounded (Anderson & Coleman, 2015; Marsick & O’Neil, 1999; Waddill & Marquardt, 2003).
Although authors have differentiated AL from other experiential methods like simulations and outdoor adventures, or other action-oriented interventions like action research (Marquardt, 1999; Marsick & O’Neil, 1999; Raelin, 2007; Raelin & Coghlan, 2006), few comparisons are made between AL and PBL. Lohman (2002) sought to classify several types of training techniques that use problem solving as a core design feature. One distinction she selected was problem type, describing PBL as using more prototypical problems compared with AL. However, given the range of problem types used in both PBL and AL, this is a less meaningful distinction than the affordances of the problem, which from a theoretical perspective can be used to explain why problem characteristics may be associated with learning outcomes. In a critique of Lohman’s classification, Mayer (2002) described the line drawn between AL and PBL as fuzzy.
Yeo and Gold (2011) also suggested that AL is distinctly different from PBL because of the problem type, how learning occurs throughout the process, and the facilitator role in both guiding learning and enforcing group norms. However, problem type and facilitation can take a variety of forms in both PBL and AL, as noted earlier and discussed in the next section. The distinction between AL and PBL in how learning occurs, described by Yeo and Gold to be “a more holistic approach where learning is largely integrated throughout the entire project through both planned and spontaneous processes” is a claim that requires more evidence (p. 514). This integrative study suggests that uniting these two approaches under a common theoretical framework will advance research and provide insights into how AL can be implemented and evaluated more effectively.
Institutional and program design factors create barriers to adopting AL in academic contexts, suggesting a need for innovative ways to integrate it into management education to support leadership development (Johnson & Spicer, 2006; Raelin, 2007, 2009). Given the widespread use of PBL in higher education and the volume of empirical studies supporting it, much can be drawn from that literature. For example, PBL research on problem characteristics like problem clarity and authenticity can offer new directions for the research and design of problems that are most suitable for leadership development purposes. In addition, AL scholars have focused on questioning and reflection techniques, and group design characteristics like team diversity, which have received relatively less attention in the PBL literature. The next section demonstrates how the characteristics that have been investigated in PBL and AL research can be merged into an integrative framework to provide a stronger conceptual and theoretical grounding for leadership development research and evaluation.
Integrative Framework for PBL and AL
Although there is a growing body of research into the underlying processes of PBL and AL, relatively fewer studies have examined which design characteristics are essential to producing desired outcomes (Cho & Egan, 2009; Hmelo-Silver, 2004; Leonard & Marquardt, 2009; Scott, 2014; Sockalingam, Rotgans, & Schmidt, 2011; Svinicki, 2007). Systematic program evaluation research in this area would help educators and practitioners make evidence-based design and implementation decisions. The complexity of program design, the multiple conceptual definitions, and numerous combinations of unspecified, interacting variables have made it difficult to make progress in this area (Cho & Egan, 2009; Hung, 2011; Mamede et al., 2006; Scott, 2014; Sockalingam et al., 2011). Another challenge is that some design characteristics are individual-level variables, whereas others are variables more properly examined at the group level of analysis (Scott, 2014). Advancing our understanding of leadership development requires research that examines its multilevel and longitudinal nature, examining both the interpersonal and intrapersonal processes that unfold over time (Day et al., 2014). For proper evaluation, it is critical to represent variable levels in theoretical and statistical models, particularly when constructs are measured at one level and specified at another level (Garavan, McGuire, & O’Donnell, 2004; House, Rousseau, & Thomas-Hunt, 1995).
To address these issues, this study builds upon earlier work (Scott, 2014) to propose an integrative framework that is multilevel, based on variables identified in prior research, and includes variables requiring further examination, such as goal orientation and scaffolding mechanisms. Table 2 presents the design characteristics and defining terms, along with their proposed relationships (i.e., input or process) with learning outcomes. Characteristics are grouped into individual- or group-level concepts from a theoretical and statistical modeling perspective. Table 2 also includes institution-level variables identified as important in understanding the effectiveness of program implementation and should be included in statistical models examining PBL effects across organizations and institutions (Chaharbaghi & Cox, 1995; Cho & Egan, 2009; Loyens et al., 2012; Neufeld & Barrows, 1974; Schmidt & Moust, 2000). Although an in-depth consideration of third-level effects is beyond the scope of this article, it is important to recognize that organizational-level characteristics such as culture and the availability of learning resources in the organization also may affect the effectiveness of the intervention and learner outcomes.
Multilevel PBL and AL Design Characteristics.
Note. PBL = problem-based learning; AL = action learning.
Figure 1 represents the individual- and group-level design variables for the integrative framework and the proposed relationships between them, based on the few existing PBL studies that have used path analysis to examine these relationships (see Gijselaers & Schmidt, 1990; Schmidt & Moust, 2000; van Berkel & Schmidt, 2000). The outcomes presented in this model are the individual-level learning objectives typically included in PBL research. The group- and organizational-level outcomes sometimes associated with AL are not discussed here. Because the focus of this integrative framework is designing and evaluating programs to improve leader capabilities, it is beyond the scope of this article to address other potential benefits that may follow from implementing PBL within organizations, such as greater knowledge sharing among participants and organizational learning. To advance the use of PBL for leadership development, it is important to identify and examine those variables believed to have an impact on the effectiveness of this technique, which is an area of study that has received less attention. Each of the design characteristics is described in more detail next, starting with the individual-level variables in the framework.

Integrative framework for PBL and AL design.
Individual-Level Characteristics: Input Variables
Problem quality
Because problems are the central feature of PBL and AL, identifying or constructing problems is a key step in design (Hung, 2009; O’Neil & Marsick, 2007). In AL, problem criteria are defined broadly and based on individual learning objectives with consideration given to strategic business issues when delivered in an organizational context. One difference between AL and PBL designs is that AL typically uses “real work” problems (Marquardt, 1999; Marsick & O’Neil, 1999; Pedler et al., 2005), whereas PBL stresses the use of real-life problems in the field (van Berkel & Schmidt, 2000). Research also suggests that AL problem criteria include problem complexity, challenge, and low familiarity (Johnson, 1998; Leonard & Lang, 2010; Marsick & O’Neil, 1999; Marquardt, 1999; Yeo & Nation, 2010). Problem quality in PBL has received more research attention as scholars began examining why PBL works. In earlier models, “problem quality,” as defined by problem statement clarity and suitability for group work and SDL, had direct and indirect effects on both student achievement and motivation (Schmidt & Moust, 2000; van Berkel & Schmidt, 2000). However, problem quality is multifaceted, and problem characteristics may have interacting or differential effects.
Some authors have defined problem characteristics as “high quality” to the extent that they trigger individual student engagement, collaborative discourse, and SDL toward desired outcomes (Mamede et al., 2006; Schmidt & Moust, 2000), but problem characteristics should be operationalized exclusive of their anticipated impact on mediating processes, such as promoting SDL. Subsequent studies have sought to extend research by more clearly defining problem characteristics (Hung, 2006, 2009; Sockalingam et al., 2011; Sockalingam & Schmidt, 2011). Drawing from PBL theory and existing evidence, four problem characteristics appear to create high-quality problems for participants: authenticity, familiarity, challenge, and clarity.
Problem authenticity
Authenticity is a ubiquitous problem characteristic in PBL and AL theory and research. To the extent that learners perceive the problem as authentic, meaningful, and related to their field of practice, they should be more cognitively and affectively engaged in solving the problem, thereby increasing the likelihood that they will learn and transfer new knowledge into practice (Hung, 2006; Innes, 2006; Leonard & Lang, 2010; Loyens et al., 2008; Marquardt, 1999; Revans, 1982; Schmidt et al., 2009; Vince, 2004; Vince & Martin, 1993; Wirkala & Kuhn, 2011). As mentioned previously, AL typically requires the problem to be an actual challenge from the organization in which the learner works, whereas in PBL the problem may not be an actual work problem depending on the program objectives. However, if problem authenticity can be established to emotionally engage participants and provide opportunities for action to solve a problem, regardless of whether learners are stakeholders within the organization, AL might become more easily implemented in management education programs.
Furthermore, it may be incorrect to assume that situating participants within their own organizations with actual work problems creates the authenticity needed to achieve learning goals. For effective leadership development, a new context may be necessary. Hung’s (2006) 3C3R model of problem design extends the conceptualization of authenticity by specifying two components for PBL: (a) contextual validity, or the practical relevance to the learner’s professional setting; and (b) the degree of problem contextualization, or the range and degree of context information provided about the problem. Both need to be considered in conjunction with the problem content and learner needs (Hung, 2006), thus the double-headed arrow between “Problem Characteristics” and “Learner Characteristics” shown in Figure 1. The 3C3R model can be applied to measure problem authenticity (e.g., the extent to which the problem is perceived to be a valid challenge faced by leaders) and compare the extent with which it affects learner motivation and development.
Problem familiarity
PBL and AL scholars have offered divergent proposals about problem familiarity. In AL design, low familiarity with the problem topic or setting is believed to be more motivating and trigger more questioning and reflection among students, thereby providing more meaningful learning opportunities (Marquardt, 1999). This proposition is supported by studies of experiential learning in leadership development based on activation theory, which suggests that motivation and arousal in cognitive processing increases when tasks are optimally unfamiliar (DeRue & Wellman, 2009). Conversely, PBL scholars suggest that unfamiliar problems prevent learners from relating to the challenge and having productive group discussions (Loyens et al., 2012; Schmidt et al., 2011). One experiment designed to compare the effects of familiar and unfamiliar problems found that student groups assigned to solve familiar problems found them to be more interesting and of higher quality than groups solving unfamiliar problems, but there were no significant differences between groups in the amount of knowledge acquired, group discussion, or time engaged in self-study (Soppe, Schmidt, & Bruysten, 2005). Conversely, Scott (2014) found that students with higher problem familiarity had significantly lower levels of perceived learning from the PBL experience, although there also were no significant associations between familiarity and student engagement in SDL and reflection.
PBL studies generally show that familiarity can have positive effects on learner interest and learning activities as well as direct effects on learning outcomes, which is consistent with theory suggesting that tasks need to be familiar to at least some group members so they may offer some scaffolding to support learning and performance (Hmelo-Silver et al., 2007; Loyens et al., 2012; Reiser, 2004; Schmidt et al., 2011; Sockalingam & Schmidt, 2011). However, given the mixed empirical results and theoretical perspectives, it is likely that the effects are more complicated and nonlinear. The interrelationship between problem familiarity, prior knowledge, and challenge is discussed next.
Problem challenge
The degree of challenge or “difficulty” level of the problem has been addressed in a variety of ways, but this characteristic is consistently included in PBL and AL descriptions alike (Barrows, 1986; Marquardt, 1999; Revans, 1982; Schmidt, 1993; Sockalingam & Schmidt, 2011; Yeo & Nation, 2010). In AL, problems can be selected either by the individual, based on a workplace issue she is facing, or by the organization for a group to tackle collaboratively. In either case, the problem must be a challenge with no predefined answer or clear process toward a solution (Johnson, 1998; Marquardt, 1999; Yeo & Nation, 2010). Similarly, PBL designs can present problems for either individuals or groups to solve, but problems must be complex, ill-structured or open-ended enough to engage learners in action to solve the problem and build a flexible knowledge base (Barrows, 1986; Hmelo-Silver, 2004; Hung et al., 2008; Loyens et al., 2012). However, several authors also note the importance of calibration between the breadth and depth of problem content and participants’ prior knowledge, so learners can integrate new and existing knowledge and engage in productive discussions without cognitive overload (DeRue & Wellman, 2009; Hung, 2006; Loyens et al., 2012).
Problem clarity
Several PBL studies suggest that problem statements that are clear, concise, and include useful key words can help participants identify learning goals, direct their learning, and have more successful SDL experiences (Hung, 2009; Sockalingam et al., 2011). Having clearly stated problems guides participants toward setting learning goals that are more consistent with the desired learning objectives, and avoid focusing on irrelevant issues that may contribute to ineffective group discussions and self-study activities (Hmelo-Silver, Chernobilsky, & Jordan, 2008; Sockalingam et al., 2011; Sockalingam & Schmidt, 2011). Because problem clarity may directly affect the level of learner engagement, designers should pay particular attention to presenting a thorough, informative statement of the problem and check to ensure participant understanding early in the process so as to avoid frustration and fruitless group discussions. The rigorous problem design process proposed by Hung (2006, 2009) offers several methods that PBL designers can use to ensure problem clarity.
Learner characteristics
Aside from SDL and prior knowledge/experience, other learner characteristics have received limited research attention in PBL (Hung et al., 2008; Loyens et al., 2012). Because SDL is an essential feature of the process, serving primarily as a mediating variable in theoretical models, it is addressed in a later section even though it also may be viewed as a learner characteristic (Loyens et al., 2008). Individual differences described under “Learning Orientation” section are included in the model even though they have not yet been widely examined in empirical studies of PBL or AL.
Experience
As discussed earlier, problem familiarity and challenge are related to the learner’s experience level, which includes the amount of prior knowledge about the problem content as well as experience with PBL. Experience plays an important role in PBL design because learners must have sufficient prior knowledge to apply during the problem-solving process, and it serves as the foundation for collaborative discourse and constructing flexible knowledge structures (Hmelo-Silver, 2004; Schmidt et al., 2011; Sofo et al., 2010). In addition, several authors have suggested and found evidence that experience has a direct, positive effect on AL outcomes, including achievement and motivation (Araz & Sungur, 2007; Raelin, 1997b; Schmidt & Moust, 2000). Theoretical and empirical PBL models suggest that the prior knowledge participants bring to PBL can have both direct and indirect effects on learning outcomes, but empirical research has been mixed and inconclusive (Gijselaers & Schmidt, 1990; Schmidt & Moust, 2000; van Berkel & Schmidt, 2000). Additional research is needed to understand these effects, particularly in leadership development contexts where participants often bring a high degree and variety of work experiences.
Learning orientation
Several authors suggest that self-efficacy, perceived control, and personality characteristics like openness may be particularly relevant for experiential learning (Araz & Sungur, 2007; DeGeest & Brown, 2011; DeRue & Wellman, 2009; Hezlett, 2016; Raelin, 1997b). Because PBL requires learners to engage in reflection, SDL, and collaborative discourse to draw meaning from their problem-solving experiences, its effectiveness may be more susceptible to these individual differences, particularly goal orientation. According to achievement goal theory, individuals differ in the extent to which they have a learning goal orientation (LGO) and a performance goal orientation (PGO) when presented with a challenge. Individuals demonstrating high LGO are comfortable engaging in challenging activities and self-improvement efforts because they believe their capabilities can be developed, whereas individuals demonstrating high PGO tend to avoid mistakes and prefer nonchallenging activities because they believe their capabilities are relatively fixed (Button, Mathieu, & Zajac, 1996; Dweck, 1986; Dweck & Leggett, 1988). Goal orientation influences how learners perceive tasks and process information, how they respond to feedback, and what actions they take to accomplish tasks (Button et al., 1996; Dierdorff & Ellington, 2012; Dweck & Leggett, 1988; Phan, 2009; Senko, Hulleman, & Harackiewicz, 2011). This research and initial empirical results suggest that participants with higher levels of LGO may also have higher engagement in the SDL required in PBL (Hezlett, 2016; Scott, 2014).
Individuals with more experience tend to have higher levels of LGO and lower levels of PGO, so goal orientation may interact with other individual-level characteristics (Button et al., 1996). Evidence also suggests that PGO negatively affects group collaboration, so PGO may interfere with collaborative discourse (Janssen, Poortvliet, Van de Vliert, & Van Yperen, 2007; Senko et al., 2011). However, studies find that both orientations can be associated with learning achievement, and with PBL’s focus on solving problems, additional research is needed to determine whether LGO and PGO are directly associated with PBL outcomes (Senko et al., 2011). Such effects may depend on the team context, discussed in a later section.
Individual-Level Characteristics: Process/Mediating Variables
Three individual-level design characteristics are process variables in PBL models: SDL, reflection, and intrinsic motivation. Because these variables are central features of PBL, as discussed earlier, the theoretical rationale will not be presented again in this section. However, because program designers can make significantly different design and implementation choices for facilitating SDL and reflection, this section highlights those areas where differences frequently occur and how they can be incorporated into this framework for evaluation purposes.
SDL
To achieve the objective of developing SDL, participants need to have the time and autonomy to engage in SDL activities with an optimal balance of scaffolding to support learning (Loyens et al., 2008; Wijnia, Loyens, & Derous, 2011). As a learning process, SDL includes selecting learning issues, planning how to solve the problem, deciding which learning resources and strategies to use, effectively managing time, engaging in self-study, and monitoring and evaluating progress (Loyens et al., 2012, Loyens et al., 2008). As a learner characteristic, SDL includes the ability and willingness to engage in these learning activities (Loyens et al., 2008; Miflin et al., 2000; van Berkel & Schmidt, 2000). SDL is similar to the “individual commitment to learning” that is a key characteristic in AL (Marquardt, 1999). But SDL goes beyond motivation and the ability to listen to include metacognitive skills and strategies that learners use to guide their learning, capabilities that designers should not assume their adult learners already have mastered through prior experience. In their review of the research, Loyens et al. (2008) found mixed support for the hypothesis that PBL develops SDL skills. Frameworks developed in medical education to address the difficulties that graduate students face when first engaging in PBL, such as the one described by Miflin and her colleagues (2000), can be adapted for leadership development programs to provide the necessary guidance for developing SDL skills. Nesbit’s (2012) framework for self-directed leadership development articulates the metaskills of self-reflective practice, managing emotional reactions to feedback, and self-regulation that HRD practitioners can use to prepare leaders for PBL.
Reflection
Reflection is another important PBL process that does not consistently receive explicit research attention. Occasionally, it is noted as an aspect of SDL (Loyens et al., 2008), but in other PBL studies, it is regarded as the key metacognitive skill and process that makes PBL effective (Hmelo & Lin, 2000; Hmelo-Silver, 2004; Hung, 2009; Kek & Huijser, 2011; Pease & Kuhn, 2011). AL scholars also emphasize the role of reflection in the learning process (Anderson & Coleman, 2015; Leonard & Lang, 2010; Yeo & Nation, 2010). Reflection is part of the meaning-making process, whereby learners seek to understand new or dissonant ideas and integrate them into their knowledge structures. Questioning is often part of the reflective thinking process, individually (metacognitively), with a facilitator, and among group members (Armstrong & Mahmud, 2008; Johnson, 1998; Kek & Huijser, 2011; Kolb & Kolb, 2009; Marquardt, 1999; Marquardt & Waddill, 2004; Phan, 2009; Yeo & Nation, 2010). To the extent that reflection is emphasized, scaffolded, and reinforced using assignments like learning journals, blogs, or diaries, it should have positive effects on SDL, collaborative discourse, and PBL outcomes.
Team-Level Characteristics
The team-level characteristics in PBL are the facilitator (including the instructional scaffolding provided for participants), team autonomy, diversity, and collaboration. The first three of these group-level variables are input variables, whereas collaboration is a process variable proposed to explain how team interactions affect PBL outcomes. For evaluative purposes, these variables are treated as group-level constructs because they create shared effects across members within a team. Measures that are similar to climate measures, which use aggregated individual-level perceptions to represent these group-level variables, may be particularly useful because they also could capture potentially interesting individual differences in perceived facilitator effectiveness and team dynamics (Scott, 2014). Furthermore, because the effects of individual-level variables may vary depending upon the group-learning context that is created by the team, modeling them as context variables can create openings for new hypotheses about cross-level interactions between individual characteristics and team context.
Facilitator and scaffolding effectiveness
Evaluating facilitator effectiveness as a group-level variable is important because facilitators usually modify their support to fit the needs of individual and team learning goals, which may result in different experiences between teams even though they may have the same facilitator (Hung, 2011; Scott, 2014). Research suggests that effective facilitation can occur even when coaches rotate between multiple teams or when participants play the role of facilitator with proper guidance (Hmelo-Silver, 2004). Facilitator effectiveness typically is gauged by their use of questioning techniques to develop metacognitive and collaboration skills, by how well they encourage team members to share knowledge, by the extent to which individuals and the team takes ownership of their learning, by the successful creation of a climate that encourages collaboration, and by the problem-solving scaffolding and learning strategies they model (Hmelo-Silver, 2004; Hmelo-Silver & Barrows, 2008; Leonard & Lang, 2010; Sofo et al., 2010; Yeo & Nation, 2010). These facilitator behaviors and scaffolding tactics are intended to directly affect PBL process variables (e.g., SDL, reflection, and group collaboration) and outcomes (individual learning and motivation) without reducing learner autonomy or providing too much instruction. Other important measures may include facilitator expertise (the extent to which participants perceive them to be experts), the amount of facilitation provided, and how effectively the facilitator reduces instructional scaffolding as learners develop their skills (Ates & Eryilmaz, 2010; Hmelo-Silver, 2004; Hmelo-Silver et al., 2007; Hung, 2011).
Team autonomy
Providing team autonomy means that teams have responsibility and authority to determine how members will collaborate and what actions they will take to achieve their shared learning objectives. Similar to the individual empowerment granted in PBL and AL, team autonomy is expected to create intrinsic motivation and a sense of ownership over the learning process (Wijnia et al., 2011). The rationale for promoting team autonomy in PBL follows the same premise as providing individual autonomy: It allows participants to practice SDL, and their ownership of the problem-solving process fosters learner engagement (Hmelo-Silver & Barrows, 2008; Liu & Fu, 2011; Rotgans & Schmidt, 2011). Participants need to have the freedom to take risks in solving the problem, stretching beyond their comfort zones, and exploring solutions that may be atypical in their usual work contexts. Organizations that rely on team-based work processes expect their leaders to develop the skills to successfully navigate team dynamics.
Yeo and Gold (2011) articulated the importance of supportive environments in providing the right environment for a collaborative and dynamic exchange of ideas. Facilitators need to strike a balance between allowing teams to set their own direction and norms versus intervening to ensure that the team sets itself up for effective collaboration, dialogue, and learning. Research suggests that conflict and disputes may be more likely in autonomous heterogeneous teams, and when members do not share the same work-related attitudes or beliefs, particularly when their tasks are unstructured (Molleman, 2005). As discussed in the next section, facilitators should be prepared to help teams address issues that arise in diverse, autonomous teams.
Team diversity
In both PBL and AL, the team diversity is viewed as important to its success, with more diversity in gender, role, age, experience, and perspective generally proposed to have a positive influence on group collaboration, decision making, and learning (Clarke, Thorpe, Anderson, & Gold, 2006; Marquardt, 1999; Marquardt & Waddill, 2004; Yeo & Nation, 2010). Team diversity may increase member access to the resources, skills, and knowledge to help them with problem solving and learning tasks (van Knippenberg & Schippers, 2007; Yeo & Nation, 2010). However, although there are many potential benefits of selecting a highly diverse team of learners, there also are negative effects to mitigate. For example, Vince and Martin (1993) suggested that power differences in AL teams can influence learning outcomes, and how such differences are managed by the team or supported by a facilitator will create opportunities for members to learn about the effects of power relations. As such, the effects of team diversity are likely to be moderated by facilitator effectiveness.
Recent research about team goal orientation and diversity also raises potential challenges for PBL design. Studies suggest that PGO in particular can have negative consequences for teams because it heightens competition and the use of guarded approaches to knowledge sharing among high PGO individuals (Janssen et al., 2007; Senko et al., 2011); thus, teams with high average PGO levels may be less likely to foster individual learning. Conversely, teams whose members share high LGO may benefit from an agreed focus on mastery. Dierdorff and Ellington’s (2012) longitudinal study of group composition effects during team training found evidence that teams with high average LGO levels may counteract the potentially negative influence of members who have high PGO, providing a “buffering effect” for team members. This raises additional questions about the moderating effects of team goal orientation and goal orientation diversity on PBL outcomes, and what designers and facilitators should do about it.
Pieterse, van Knippenberg, and van Ginkel (2011) characterized goal orientation diversity as deep-level diversity that influences mental representations of tasks and routines. A high degree of variance in the LGO and PGO within teams may result in less effective group collaboration and performance because individual differences in task representations disrupt team coordination and communication (Scott, 2014). Facilitators can help teams establish shared mental models of team learning to minimize negative effects of goal orientation diversity, so scaffolding mechanisms and reflection may be key moderators (Pieterse et al., 2011). To improve PBL design, goal orientation can be measured prior to making learning team assignments so that high levels of team diversity or cases of member dissimilarity can be monitored and their effects closely examined.
Learning team collaboration
The dialogue, practices, and learning environment within the team form this essential mediating process—team collaboration—that allows learners to achieve their objectives and practice SDL activities (Dolmans & Schmidt, 2006; Gijselaers & Schmidt, 1990; Hmelo-Silver & Barrows, 2008; Hmelo-Silver et al., 2008; Innes, 2006; Johnson, 1998; van den Hurk, Dolmans, Wolfhagen, & van der Vleuten, 2001). This mediating process involves “team commitment to learning,” which is a norm described in both PBL and AL research as members taking responsibility for learning, sharing expertise, and collaborating effectively in small groups (Hmelo-Silver & Barrows, 2008; Hung, 2011; Marquardt, 1999). Studying these concepts is difficult because they are complex and dynamic, involving not only the language and conversation patterns participants use but also the tools and resources they apply during the process (Hmelo-Silver et al., 2008). Ideally, PBL team members will support each other as they work toward a common goal while constructively questioning each other’s ideas and having an open dialogue about their experiences (Innes, 2006; Johnson, 1998). In practice, teams may rarely achieve this level of collaboration, instead opting for the “divide and conquer” method of problem solving that improves efficiency but sacrifices the benefits of conversation (Innes, 2006).
Evidence about the importance of social interaction and collaborative learning is mixed (Clarke et al., 2006; Nieminen, Sauri, & Lonka, 2006; Wirkala & Kuhn, 2011). Such studies reinforce the importance of carefully designing for and facilitating collaboration while measuring the extent to which it actually occurs. Because these team processes are shared and norms develop over time, measurement strategies must address the fact that this is a group-level variable that includes individual perceptions of the team environment.
Discussion and Conclusion
This article bridges the PBL and AL research to propose an integrative framework for leadership development design and evaluation. Although authors have noted that group- and individual-level factors influence learning outcomes (Cho & Egan, 2009; Loyens et al., 2012), this framework proposes a comprehensive approach for examining contextual effects not typically included in PBL or AL evaluation studies. To produce the evidence needed to build confidence in leadership development initiatives, practitioners can include measures of participant characteristics, problem characteristics, process variables, and outcomes as an integral part of implementation. By including measures for all parts of the integrative framework—before, during, and after implementation—program designs can be compared to improve our understanding of what works and why. Deciding what to measure, and how and when to measure it, is not only a strategic move toward evidence-based design but also a mechanism for achieving learning objectives.
One assumption underlying this suggested approach is that the design characteristics and overall effectiveness of constructivist learning approaches like PBL and AL can be evaluated successfully using positivist, quantitative methods. The constructivist learning foundations of PBL and AL might seem to be in stark contrast to the positivist lens used here to define the integrative framework. However, the PBL literature provides numerous quantitative studies using modeling and experimentation to examine design effectiveness (see Hung, 2011; van Berkel & Schmidt, 2000). In their meta-analysis of 270 PBL curriculum comparisons, Schmidt and colleagues (2009) pointed to the high-stakes nature of medical education and the medical field’s tradition of large-scale investigations into treatment effects as reasons why there have been numerous PBL comparison studies: “From this, it is a small step to apply this approach to educational treatments as well” (p. 231). Because of PBL’s popularity in education programs, researchers have access to large student populations and standard measures of outcomes (e.g., tests of knowledge and skills) that are less common in organizational settings.
By contrast, AL research has been dominated by qualitative program descriptions, and there are few peer-reviewed empirical studies that report findings from high-quality research (Cho & Egan, 2009). Of the 50 empirical studies identified by Cho and Egan (2009), 74% used a case study design, a trend that earlier literature reviews also had noted. AL research must become more inclusive of methodologies that will allow for experiments and questions to be answered about the impact of specific practices on leader and organizational performance (Allio, 2005; Cho & Egan, 2010; Garavan et al., 2015). Steps to improve evaluation methods while adding more precision by defining and measuring design characteristics with greater consistency and accuracy may allow HRD professionals to make more decisive statements about leadership development effectiveness that is called for in the literature (Garavan et al., 2015; Hannum & Craig, 2010). To advance our understanding of experience-driven leadership development, quantitative studies, careful operationalization of variables with reporting of instrument validity and reliability, and additional methods are needed so that effect sizes can be generated and compared (Cho & Egan, 2009; Hezlett, 2016; Hung, 2011)
Table 3 presents a sample measurement schedule that could be used to plan for and track measures. This table reveals the challenges faced by researchers and practitioners as they consider how to thoroughly assess a complex intervention like AL and PBL. It is overwhelming to see the number of variables and measurement frequency required to examine how and why these designs work. Fortunately, a variety of sources, such as multirater feedback tools, self-assessments, performance management systems, learning journals, facilitator observations, and program evaluation surveys, can be used to gather such data in organization contexts. And, measures can be used for multiple purposes. For example, participant characteristics and perceived problem affordances are inputs for design and also useful assessment results to discuss with participants as they experience PBL, make sense of their reactions, and develop their SDL skills. Ongoing measures of learner motivation, reflection, SDL skill, and team collaboration may indicate opportunities for facilitator intervention or a need for additional scaffolding mechanisms. Several studies report that learners initially feel anxious and frustrated with the PBL process, and that an environment fostering risk-taking and learning from mistakes is critical for effective implementation (Barrows & Mitchell, 1975; Hung et al., 2008; Johnson & Spicer, 2006; Miflin et al., 2000; Raelin & Raelin, 2006). Repeated measures of these variables can help facilitators monitor participant engagement, understand the causes of participant reactions, and introduce resources or instruction when needed. Entries from reflection journals, blogs, or discussion posts can be evaluated to measure levels of reflection and metacognitive skill development.
Sample Measurement Schedule for Evidence-Based PBL and AL Design and Implementation.
Note. PBL = problem-based learning; AL = action learning; SDL = self-directed learning.
With the appropriate levels of the variables established in the framework, researchers can apply hierarchical linear modeling to examine individual- and group-level relationships (Scott, 2014). To effectively apply this technique, validated measures are needed to examine these design characteristics. Although authors have measured process and outcome variables like reflection and critical thinking using participant surveys (e.g., Phan, 2009), alternative approaches to evaluate learning artifacts or behaviors would provide stronger evidence and allow for triangulation of data collected from surveys. PBL research such as the study by Visschers-Pleijers, Dolmans, De Leng, Wolfhagen, and van Der Vleuten (2006) provides a model for how variables like collaborative learning behaviors can be coded to understand team processes.
The framework provided in this article is intended to encourage PBL and AL scholars to leverage the efforts across their respective fields to improve the design of leadership development programs. There are more similarities than differences between PBL and AL approaches. In their review of the AL literature, Cho and Egan (2009, 2010) identified the need for additional conceptual and theoretical development to advance research. Using this integrative framework, PBL and AL scholars can improve our understanding about how these initiatives work and encourage consistent measurement strategies that will produce evidence for ongoing design.
