Abstract
There are declines in learning outcomes despite teacher’s efforts to attain the lesson goals and objectives. The application of technology in education paved way for constructive teaching and learning, which made the evaluative processes convenient. Hence, this study investigated system quality, technology acceptance model and theory of planned behaviour models as an agent to adopt blended learning tools. The sample used for the study was 1200 students from seven public higher institutions in Lagos State using a stratified sampling technique to select the students from their respective colleges. A seven-point Likert scale was used to collect data from the selected samples. SmartPLS3 was used to analyze the data using the bootstrapping method. It was found that system quality influences the perceived ease of use, perceived usefulness, attitude, subjective norms, perceived behavioural control towards intentions to use and culminated into actual usage of blended learning. Also, there is a strong mediating influence of system quality and the antecedents of technology acceptance model as against the theory of planned behaviour towards the actual usage of blended learning. Therefore, education institutions will have to create enabling classroom environment and quality blended learning tools which gives the facilitators the privilege to interact well with the learners and the subject matter without abrupt alteration of the lesson processes/procedures.

Introduction
There are declines in learning outcomes despite teacher’s efforts to attain the lesson goals and objectives. These declines are adduced to several factors ranging from teacher’s personality, classroom/school environment, learners’ personality and non – interactive instructional media (Falout et al., 2009; Hawlitschek and Joeckel, 2017). For effective learning outcome, Darling – Darling– Hammond et al. (2020) highlighted four major engaging areas that should be considered in the school system: supportive environmental conditions, productive instructional strategies, social and emotional learning strategies and system supports. Fortunately, some institutions have begun to implement the innovative practices which enhance teacher’s pedagogical skills so as to address most common challenges to ensure rigor and comparability (Lachan-Hache et al., 2012).
The adoption of technology and its application to education has paved way for constructive teaching and learning with considerable and convenient evaluative process. The choice of blended learning over the long known traditional teaching has shaped the learning outcome and could be seen as an essential element in education (Mozelius and Hettiarachchi, 2017). Blended learning plays a dual role by allowing the teachers to deliver their lesson and as well evaluate learners by using a creative and innovative method (Khan et al., 2012).
The successful use of blended learning tools in the classroom is reliant on the quality of the tools/system used. System quality is a measure of the information processed by the system; it entails the compatibility level of the hardware and the software (Al-Mamary et al., 2014). System quality also refers to the characteristics of the whole system, such as response time, completeness of functionalities, availability and reliability of the system, ability to handle large number of user requests in a timely manner, minimal interruptions or bottlenecks, and strong security measures in place to prevent security risks (Gan and Balakrishnan, 2017). Delone and McLean (2003) is of the opinion that higher system quality is expected to lead to higher user satisfaction and use, leading to positive impacts on higher outcome. Therefore, system quality affects the rate and consistency in which teachers and learners use blended learning tools to facilitate learning. The outcome of this research study will have both theoretical and practical implication which will stimulate the adoption of blended learning among electrical installation and maintenance work students in public higher institutions.
Electrical installation and maintenance work (EIMW) students are the ones under training in a skilled subject area that teaches industrial and domestic installation of electricity, rural electrification, electrical machines (motors and generators), inspection, testing and maintenance of electrical/electronic devices (Shodipe and Ohanu, 2021). Ohanu, Shodipe, Chukwu and Chukwuma (2020) stated that EIMW is an area of specialization in technical vocational education and training offered colleges of education (technical), polytechnics and universities in Nigeria, designed to impart knowledge and practical skills in electrical engineering trade area such as house wiring (conduit and surface), coil winding and re-winding, electrical gadgets repairs, installation and maintenance of electrical machines, battery charging, installation and maintenance of electric motors, rural electrification etc. The adoption of blended learning tools in EIMW in Nigeria is low (Kintu et al., 2017; Orji et al., 2021) as compared to the adoption of blended learning tools among vocational technical education and training in developed countries (Orji et al., 2021). This bridges the widening gap between teachers and learners and foster consistent interaction between them.
Despite the several rigorous researches on the application of blended learning to teaching and learning activities (Hongli et al., 2011; Qian 2011; Kintu et al., 2017; Ibrahim and Nat, 2019; Westerlaken et al., 2019), this study focused on the influence of system quality, technology acceptance model (TAM) and theory of planned behaviour (TPB) as an agent to adopt blended learning tools. Specifically, the research study tends to find out the influence of the constructs of TPB, TAM and C-TAM-TPB on the relationship between quality systems used and blended learning activities with verifiable evidences. A structural equation model (SEM) which is an advanced multivariate analysis method was adopted for the analysis in the study as it good and consistent approach to analyze a cause and effect relationship between factors (Hair et al., 2014). In this study, SEM allows several constructs of TAM and TPB to simultaneously predicted or expressed by the construct of system quality which will lead to cogent validities, conclusion, verifiable reliabilities of the results (Nachtigall et al., 2003).
Theoretical background and hypotheses
Blended learning
Blended learning is an integration of face – to – face and online component of education (Margolis, 2018). It is adopted to support interactions between students in the online mode and improve learning outcomes (Bojović, 2017; Islam et al., 2021). Blended learning did not only enhance teaching and learning process through online or mobile technologies but also bridge the gap between learning and working (Garrison and Kanuka, 2004; Vaughan, 2007; Bohle-Carbonell et al., 2013). Blended learning facilitates communication and collaboration among students and teachers through social networking, increases the ease of use of course materials (Wai and Seng, 2013), decrease physical class time, create a student-based learning environment, produce an encouraging learning environment, flexible learning time and location, promotes independent learning skills, and develops individually course solutions (Rahman et al., 2015; Siew-Eng and Muuk 2015). Littlejohn and Pegler (2007) and Zavyalova (2020) lay much emphasis that blended learning reduced the cost of student’s travel as compared to the traditional method of learning.
Blended learning is categorized into four major taxonomies which are: rotation model, flex model, self – blend model and enriched virtual model (Staker and Horn, 2012). Staker et al. (2011) explained blended learning by focusing on the learners rather than the instructors. This allows learners to learn at any time at a supervised brick and mortar location away from home and at least in part through online delivery with some element of student control over time, place and pace. Staker and Horn (2012) and Staker et al. (2011) explained rotational model as a program in which within a given course or subject, students rotate on a fixed schedule or at the teacher’s discretion between learning modalities, at least one of which is online learning. In flex model, content and instruction are delivered primarily by the Internet, students move on an individually customized, fluid schedule among learning modalities, and the teacher-of-record is on-site. The self – blend model describes a scenario in which students choose to take one or more courses entirely online to supplement their traditional courses and the teacher-of-record is the online teacher and the virtual model is a whole-school experience in which within each course, students divide their time between attending a brick-and-mortar campus and learning remotely using online delivery of content and instruction (Staker and Horn, 2012; Staker et al., 2011).
Blended learning tools are technology devices used as an effective mechanism for adequate lesson delivery (Castro, 2019; Basal, 2011). He explained three major importance of adopting technology into education as: increases the diversity of mechanism and modes in education, decreases barrier to education as a democratization mechanism and enhances individual control over one’s own education in terms of content, delivery mode and pace of learning.
Technology acceptance model
Technology acceptance model is a salient scientific model with several empirical evidences on the application of information technology which cut across many fields of study. Technology acceptance model found its root from TRA (Davis, 1989), with the prime objective to explain a clincher for the user to accept information technology, verifying the theory and explaining the users’ behaviour. (Chen and Chen, 2009). Technology acceptance model focuses on either information technology (IT) systems in use by individuals or systems with which users are familiar; however, TAM’s ability to predict the inexperienced user’s behaviour and the differences between experienced and inexperienced users in terms of use behaviour is unclear (Taylor and Todd, 1995a; Ho et al., 2013).
Technology acceptance model has two main constructs (perceived ease of use and perceived usefulness) (Moon and Kim, 2001). Perceived ease of use is the extent to which a perspective user expects that using a system is free from effort while perceived usefulness is the subjective probability that using a particular system enhances job performance (Davis et al., 1989; Hsiao and Tang, 2013). Technology acceptance model posit that perceived ease of use and perceived usefulness will influence the formation of favourable attitude associated with the use of a technology system which in conjunction with perceived usefulness will generate individuals’ behavioural intention to use the technology system. Also, perceived ease of use is expected to have a positive influence on individuals’ perceptions regarding the usefulness of the technology system (Ma et al., 2017; Davies et al. 1989)
Technology acceptance model constructs are actual usage, behavioural intentions to use, attitude, perceived ease of use and perceived usefulness (Venkatesh and Davis, 2000). Taylor and Todd (1995b) emphatically describe the model constructs in a way that clarify their functions. Perceived ease of use have a direct linkage to perceived usefulness, perceived ease of use and perceived usefulness have a direct linkage with attitude towards usage but having an indirect linkage with behavioural intentions to use, users attitude directly linked with an ideal to influence behavioural intentions to use, behavioural intentions to use direct linked but plays a mediating role between actual usage and other constructs of TAM and actual usage which is motivated by the conditions of the other construct. Davis et al. (1989) proposed the effect of exogenous variables to enhance the robustness of TAM and found a strong correlation between user intentions, self – reported usage with perceived usefulness owing to a great influence on the users’ intentions as it was proposed in our model in Figure 1. As a result of divergent opinions and users’ perception of IT and based on empirical review of previous studies of Rahiet al. (2017); Lu et al. (2003); Hu et al. (1999); Szajan, 1996) on TAM, we hypothesized that: 1. Student’s behavioural intention influences their actual usage of blended learning tools. 2. Student’s perceived ease of use influences their actual usage of blended learning tools. 3. Student’s perceived ease of use mediates the relationship between behavioural intentions and actual usage blended learning tools. 4. Student’s perceived ease of use mediates the relationship between their attitude and behavioural intentions towards use of blended learning tools. 5. Student’s perceived ease of use enhances their perceived usefulness of blended learning tools. 6. Student’s perceived usefulness enhances their attitude towards the adoption of blended learning tools. 7. Student’s perceived usefulness mediates the relationship between attitude and behavioural intentions to use blended learning tools. 8. Student’s perceived usefulness influences their behavioural intentions to adopt blended learning tools. 9. Student’s perceived ease of use influences their behavioural intentions to adopt blended learning tools. 10. Student’s perceived ease of use influences their attitude towards the adoption of blended learning tools. 11. The relationship between student’s perceived usefulness and behavioural intentions is mediated by perceived ease of use of blended learning tools. 12. The relationship between student’s perceived usefulness and attitude is mediated by perceived ease of use of blended learning tools. Theoretical framework and hypotheses.

Theory of planned behaviour
The theory of planned behaviour (Ajzen, 1991), is an extension of theory of reasoned action (TRA) (Ajzen and Fishbein, 1975). It parsimoniously gives an explanation about the motivational influences on behaviour (Conner and Armitage, 1998). It also predicts non-volitional behaviour by incorporating perceptions of control over performance of behaviour as an additional predictor (Ajzen, 1991). TPB holds a tentative statement of fact that intentions to perform a behaviour is founded on: attitude, subjective norms and perceived behavioural control (Ajzen, 1991). Attitude is the “degree to which a person has a favourable or unfavourable evaluation or appraisal of certain behaviour (Ajzen, 1991). It is an individual’s disposition to react with a certain degree of favourableness or unfavourableness to an object, behaviour, persons or an event (Ajzen, 1993). Subjective norm is the social component in the TPB model which speaks to a person’s perception of how significant others view his/her behaviour in question and whether or not they would endorse the practice. Significant others can include persons such as family members and friends whose support or lack thereof of a particular behaviour can influence intentions to act or not to act (Fishbein and Ajzen, 1985; Carpenter and Reimers, 2005). Perceived behavioural control can be viewed as an individual’s perception of ease or challenging it may be to perform the behaviour (Ajzen, 1991). Ajzen (2002) defined perceived behavioural control as the “perceived ease of use of performing the behaviours based on past experiences and anticipated impediments.”
Krueger and Carsrud (1993) postulated that exogenous factors/variables could serve as antecedents of behaviour or influence the intentions – behaviour relationship. In Figure 1, system quality serves as an exogenous variable that influences behavioural antecedents and stimulates the intention – behaviour relationship towards IT usage. Empirically, compatibility, peer influence, superior’s influence, self – efficacy, resource facilitating condition, technology facilitating condition, trust has been used to test the strength of TPB model (Taylor and Todd, 1995a; Wu and Chen, 2005) but this study adopted system quality as an exogenous variable that will enhance TPB model. Hence, we hypothesized that: 13. Student’s attitude influences their behavioural intentions to adopt blended learning tools. 14. Student’s subjective norms influence their behavioural intention to adopt blended learning tools. 15. Student’s perceived behavioural control enhances their behavioural intentions to adopt blended learning tools. 16. Student’s subjective norms mediate the relationship between behavioural intentions and actual usage of blended learning tools. 17. Student’s perceived behavioural control mediates the relationship between behavioural intentions and actual usage of blended learning tools. 18. Student’s subjective norms influence their actual usage of blended learning tools. 19. Student’s perceived behavioural control influence their actual usage of blended learning tools.
System quality and C-tam-tpb
The two models have been used to explain the factors that influence behavioural intentions in many studies of IT adoption and usability (Ramayah et al., 2009). Theory of planned behaviour looked into three antecedents that enhance intentions while TAM was also channeled in the same course but contained different antecedents fused to enhance behavioural intentions (Nadlifatin et al., 2020). Taylor and Todd (1995a) held that TAM failed to include factors of society and control that have been proven to affect actual behaviours. The two factors are also key factors in TPB. As a result, Taylor and Todd (1995b) integrated TAM and TPB to include subjective norm and perceived behavioural control into technology acceptance models and proposed C – TAM – TPB.
As earlier explained, this research study is on the influence of exogenous variables on TAM and TPB models. System quality was adopted as an independent variable with strong exogenous influence on the adoption, flexibility and usability of blended learning tools. A system displaying high data quality and system quality can lead to net benefits for individuals, group of individuals and institutions (Seddon, 1997). It can give user’s an understanding of the decision context, increase decision making productivity and change how certain tasks is performed (Wixom and Watson, 2001). System quality is a desirable characteristic of an information system which involves ease of use, flexibility, reliability, ease of learning, intuitiveness, sophistication and response time (Petter et al., 2008; Al-Mamary et al., 2014). System quality is the quality of the information system processing itself which includes software and data components and it is a measure of the extent to which the system is technically sound (Gorla et al., 2010). It is an important factor to be considered in the selection of IT tools to be used in the classroom, as good and quality IT system may foster users’ behaviour to use and poor quality may hinder lasting and adequate usability. From the personnel perspective, system quality is thought to be an important motivating factor for people to use their systems and derive any benefits essential for organizations to gain a return on their investment (Rai et al., 2002; Guimaraes et al., 2017).
The relationship between system quality and C-TAM-TPB cannot be neglected as long as IT application is concerned, although previous studies have discussed the relationship between TAM, TPB, C–TAM–TPB and other variables (Taylor and Todd, 1995b; Wu and Chen, 2005; Chen and Chen, 2009), C-VBN-TPB (Chen, 2020), C-TPB-EEM (Sharahiley, 2020) but few has discussed the relationship between system quality and C – TAM – TPB. This ideal formed the basic objective of this research study. Hence, we hypothesized that: 20. System quality mediates the relationship between student’s perceived ease of use and student’s perceived usefulness of blended learning tools. 21. System quality influences student’s perceived ease of use of blended learning tools. 22. System quality mediates the relationship between student’s perceived usefulness and attitude towards the usage of blended learning tools. 23. System quality influences student’s subjective norms towards the usage of blended learning tools. 24. System quality enhances student’s perceived behavioural control towards the usage of blended learning tools. 25. System quality influences student’s attitude towards the usage of blended learning tools. 26. System quality influences student’s perceived usefulness of blended learning tools.
Methodology
This study was conducted among students who study electrical installation and maintenance work in colleges of education (technical), polytechnics and universities in Lagos State in the south west region of Nigeria. The area of focus is suitable for the study because this category of students has had the privilege to use blended learning tools at some stages in their learning institutions.
Sample
The sample selected for the study was 1200 Electrical Installation and Maintenance Work students; this was as a result of the accurately filled instrument for data collected from the 1500 copies initially produced and administered. This gave 80% return rate of the administered instrument. A stratified sampling technique was used to select sample from the technical vocational education and training institutions which gave the opportunity for the selection of students from seven TVET institutions from the zone. Among these respondents 980 (81.67%) were male, 220 (18.33%) were female, 780 (65%) were in their final year, 300 (25%) were in their second year and 120 (10%) were in their first year. The average age of the respondents falls between 18 – 22 years.
Instrument for data collection
The instrument used for data collection was adapted from various previous research works to suit the purpose of the study. The instrument contained four segments that addressed the demography, technology acceptance model constructs, theory of planned behaviour and system quality. The constructs contained are perceived usefulness (PU) – 4 items (Venkatesh and Davis, 1996, 2000; Pavlou, 2003), perceived ease of use (PEOU)– 4 items (Venkatesh and Davis, 1996, 2000; Wu and Chen, 2005), attitude (AT) – 4 items (Bhattacherjee, 2000; Ajzen, 1991), subjective norm (SN) – 3 items (Taylor and Todd, 1995a; Bhattacherjee, 2000; Ajzen, 1991), perceived behavioural control (PBC) – 3 items (Bhattacherjee, 2000; Ajzen, 1991), behavioural intention to use (BI)– 3 items (Venkatesh and Davis, 1996, 2000; Taylor and Todd, 1995a), actual usage (AU) – 4 items (Doll and Torkzadeh, 1998) and system quality (SQ)– 7 items (Alsabawy et al., 2016). The instrument was measured on a seven point Likert scale of 7(Strongly agree) – 1(Strongly disagree).
Data analysis
The instrument for data collection was distributed to two experts from the field of Computer Education and Robotics from the Faculty of Vocational Technical Education, University of Nigeria, Nsukka and Education Technology Department, Federal College of Education (Technical) Akoka who checked the content structure of the instrument. Their corrections were used to produce the final copies of the questionnaire distributed for data collection. The data collected for the study was analyzed using Partial Least Square analysis technique with SmartPLS 3.0 software (Ringle et al., 2015). The analysis of the data was done with measurement model testing (validity and reliability of the construct), structural assessment model and hypotheses testing based on Hair et al. (2014) recommendations.
Measurement model testing
Measurement of the various items of the constructs was tested to ascertain its validities and reliabilities. This is the stage of measurement modeling where Cronbach alpha reliability, convergent validity and composite reliability were ascertained as recommended (Lee et al., 2007). The process shows the extent to which the measured items fit appropriately into the model (Henseler et al., 2009).

Structural assessment model
In this segment, the proposed model, measures and the tentative statement of hypothesis are further verified. The lateral collinearity test (VIF), coefficient of determination (R2), cross – validated redundancy (Q2), path coefficient and the effect size (f2) were considered as recommended by Hair Jr et al. (2016) to assess the structural equation model.
Effect size (f2) and lateral collinearity test (VIF).
Hypothesis testing
A bootstrapping method was used to calculate the various estimates to enable the acceptance or rejection of the stated hypothesis. The result yielded various parameters of t – statistics, p – value, original sample and sample mean. A limit bound threshold t – value of 1.96 and its equivalent p - value less than 0.05 which indicate that the hypotheses are accepted at 95% confidence interval (Kock, 2016). Figure 3 and Table 5 showed the result of the path coefficients and decisions on the various constructs. Therefore, H5, H6, H9, H10, H13, H15, H19, H21, H23, H24, H25 and H26 are significant and accepted as having a direct effect on their dependent variables. Structural model of the construct.

Coefficient of determination (R2) and cross – validated redundancy (Q2).
The average variance explained (R2) for endogenous variables should be greater than or equal to 0.10 to be adequate (Falk and Nancy, 1992) but Chin (1998) was emphatic that R2 should have a threshold of 0.67 (substantial), 0.33 (moderate) and 0.19 (weak). Hence the R2 value explained in Figure 2 for attitude, behaviour intentions, perceived behavioural control, perceived ease of use, perceived usefulness and subjective norms are moderate and substantial but actual usage is weak with the R2 = 0.043. Also, the effect size (f2) for each path in the model was determined with a threshold of 0.02(small), 0.15 (medium) and 0.35 (large) (Cohen, 1988; Hair Jr, et al., 2014). The cross – validated redundancy (Q2) measures the inner model’s predictive relevance. Q2 greater than 0 for particular endogenous variables is an indicator that the path model’s predictive are relevant (Rigdon, 2014; Sarstedt et al., 2014). The Q2 for the endogenous variables in this study are greater than 0 which indicates that endogenous variable predicted in the model are relevant.
Discussion of the findings
The purpose of the study was to examine system quality, TAM and TPB as an agent to adopt blended learning tools. System quality as an exogenous variable played a major role that significantly and substantially predicts electrical installation and maintenance work student’s perceived ease of use and perceived behavioural control, likewise, moderately predicts their subjective norms, attitude and perceived usefulness to use blended learning tools. It motivates the electrical installation and maintenance work students with the intentions to either use blended learning tools or not, to enhance teaching and learning activities in the classroom.
The result of the study showed that there is a significant influence of behavioural intentions on actual usage of blended learning tools. Hence, H1 is accepted. The result of the study is consistent with previous literature on intention – actual usage relationship (Shih and Huang, 2009; Arlt et al., 2011; Alleyne and Lavine, 2013). This is an indication that the result of the study supports that intentions is a strong predictor of actual usage (Ajzen, 1991). Also there is an insignificant influence of perceived ease of use on actual usage of blended learning tools. Therefore, H2 is rejected. The result of the study is inconsistent with previous studies that found significant relationship (Ngai et al., 2007; Lu et al., 2010; Letchumanan and Tarmizi, 2011). The result of the study showed an insignificant mediation effect of perceived ease of use on the relationship between behavioural intentions and actual usage of blended learning tools. This makes H3 to be rejected. The result of the finding showed that intentions influence actual usage of blended learning tools but mediating the mediation of PEOU on their relationship reduced the predictive ability of intentions on actual usage. Likewise, there is a significant mediating influence of perceived ease of use on the relationship between attitude and behavioural intentions to use blended learning tools. Therefore, H4 is accepted. The result of the finding indicated a reasonable relationship between attitude and intentions to use blended learning tools. PEOU increases the predictive effective of attitude on intention with significant mediation. Hence, PEOU will not only influence their attitude but also their intentions. Also, there is a significant influence of perceived ease of use on perceived usefulness of blended learning tools, which allowed H5 to be accepted. This result is consistent with previous studies that found a significant relationship between PEOU and PU (Abdullah et al., 2016; Chen and Tung, 2007; Van de Heijden, 2003). There is a significant influence of perceived usefulness on student’s attitude to use blended learning tools. This allowed H6 to be accepted. The result of the study found credence in the result of some previous studies (Van de Heijden, 2003; Ngai et al., 2007; Davis, 1993). There is a significant mediating influence of perceived usefulness on the relationship between attitude and student’s behavioural intentions. Hence, H7 is accepted. The result of the finding showed that there is a strong mediation influence of perceived usefulness on attitude and intention. This is an indication that attitude predicts intentions through perceived usefulness. Also, perceived usefulness has an insignificant influence on behavioural intentions to use blended learning tools which allowed H8 to be rejected. Hence, the result of the study does not align with previous studies that found a significant relationship between the constructs (Chang and Tung, 2007; Venkatesh and Davis, 2000). Morealso, there is a significant influence of student’s perceived ease of use on their attitude towards the use of blended learning tools. This allowed H9 to be accepted. The result of the findings is concordance with previous literature of the constructs of TAM (Van de Heijden, 2003; Venkatesh and Davis, 2000). There is a significant influence of perceived ease of use on student’s attitude to use blended learning tools. Therefore, H10 is accepted. The result of the findings is consistent with some previous literatures (Renny et al., 2013; Van de Heijden, 2003; Ngai et al., 2007). There is an insignificant mediating influence of perceived ease of use on the relationship between perceived usefulness and student’s behavioural intention to use blended learning tools. Hence, H11 is rejected. The result of the findings showed that intention is not influenced by perceived usefulness of blended learning tools. Likewise, the link between perceived usefulness and intention is not predicted by perceived perceived ase of use. This is an indication that the way users’ perceived the usefulness or ease of use of blended learning tools do not influence their intentions. Also, there is a significant mediating influence of perceived ease of use on perceived usefulness and student’s attitude towards the use of blended learning tools. Therefore, H12 is accepted. The result of the findings showed that perceived usefulness influenced the attitude towards the intentions to use blended learning tools. The attitude and intention relationship is strongly mediated by perceived ease of use. This implies that attitude through ease of use will increase intentions to use blended learning tools.
There is a significant influence of attitude on student’s behavioural intentions to use blended learning tools. This allowed H13 to be accepted. The result of the findings found credence in previous literature (Lin, 2010; Letchumanan and Tarmizi, 2011; Stoel and Lee, 2003). Also, subjective norms have an insignificant influence on student’s behavioural intentions to use blended learning tools, therefore, H14 is rejected. This result of the findings is consonance with some previous literature (Asadi and Abdekhoda, 2019; Trafimow, 2000; Suki and Suki, 2017). This is an indication that respondents believed that encouragement from people who are important to them only minimally influence their intention to use blended learning tools. Likewise, they were less likely to appreciate the sentiment of those whose opinion they value regarding the usefulness of the tools (Kim et al., 2009; Suki and Suki, 2017). Student’s perceived behavioural control significantly influenced their behavioural intentions to use blended learning tools. Hence, H15 is accepted. The result of the findings aligns with the result from previous studies on the relationship between perceived behavioural control and behavioural intentions (Lin, 2010; Richard and Meuli, 2013). There is no significant mediation influence of subjective norms on the relationship between student’s behavioural intention and actual usage of blended learning tools. Therefore, H16 is rejected. The result of the findings showed that there is a strong relationship between intentions to use and actual usage of blended learning toolls but this relationship is not mediated by their subjective norms. There is no mediating influence of perceived behavioural control on the relationship between student’s behavioural intention and actual usage of blended learning tools. Hence, H17 is rejected. The result of the findings showed that there is a strong relationship between intentions to use and actual usage of blended learning tools but the relationship is not mediated by their perceived behavioural control. There is no significant influence of student’s subjective norms on actual usage of blended learning tools. Therefore, H18 is rejected. The result of the findings is inconsistence with some previous studies that found otherwise (Alzahrani et al., 2016; Salleh and Laxman, 2014; Hsu and Lu, 2007; Lee and Tsai, 2010). But, there is a significant influence of student’s perceived behavioural control on their actual usage of blended learning tools. This allowed H19 to be accepted. The result of the findings is consistent with the findings in previous literature where perceived behavioural control has strong positive influence on actual usage (Gopi and Ramayah, 2007; Yulihasri, 2004; Taylor and Todd, 1995a)
Also, there is a significant mediating influence of system quality on the relationship between student’s perceived ease of use and perceived usefulness of blended learning tools. Therefore, H20 is accepted. The result of findings indicated a strong relationship between perceived ease of use and perceived usefulness. Hence, the relationship is strongly mediated by system quality. System quality influence student’s perceived ease of use of blended learning tools. Hence, H21 is accepted. The result of the finding is coherent with previous studies that found significance between TAM constructs and their exogenous variables (Abdullah et al., 2016; Al-Mamary et al., 2014; Al – Gahtani, 2016). There is a significant mediation influence of system quality on the relationship between student’s perceived usefulness and attitude towards the adoption of blended learning tools. This allowed H22 to be accepted. The result of the findings indicated a strong relationship between perceived usefulness and attitude. The relationship is mediated by system quality which implied that users’ attitude could be predicted when quality blended learning tools is perceived. There is a significant influence of student’s system quality on their subjective norms to use blended learning tools. Hence, H23 is accepted. The result of the findings is in consonance with existing literatures where system quality had significant relationship with subjective norms (Grimes and Marquardson, 2019; Al – Nawafleh, et al., 2019). There is significant influence of system quality on student’s perceived behavioural control to use blended learning tools. Therefore, H24 is accepted. The result of the finding is line with previous literature where system quality and perceived behavioural control had significant relationship (Grimes and Marquardson, 2019; Al – Nawafleh et al., 2019). There is a significant influence of system quality on student’s attitude to use blended learning tool which allowed H25 to be accepted. The result of the finding is in consonance with previous literatures that found system quality as a strong predictor of users’ attitude (Kleijnen et al., 2004; Yun, 2013). Also, there is a significant influence of system quality on student’s perceived usefulness of blended learning tools. Therefore, H26 is accepted. The result of the finding is consistent with previous literature that found significant relationship between perceived usefulness and some exogenous variables (Abdullah et al., 2016; Pituch and Lee, 2006; Lau and Woods, 2008; Lee et al., 2011; Abbad et al., 2009).
Implication
The findings in this study have implication on the theoretical framework used in the adoption of blended learning tools in both technology acceptance and behavioural theory. Since, attitude significantly predicts behavioural intentions and intentions culminated into actual usage of blended learning tools. Then the combination of TAM and TPB model in predicting the adoption of blended learning tools is a good channel for system quality construct. System quality having a significant relationship with the constructs of TAM model and TPB model will motivate the learners or users to adopt blended learning tools which will culminate into actual usage of such tools in the teaching and learning process.
As a result of the changing technologies and quality of blended learning tools which has greater influence on students intentions to use and actual usage of blended learning tools. School management should endeavour to provide blended learning tools that will not only enhance learning instructions but that will provide quality graphics for visual media, sound and pictures for audio – visuals and that is sustainable to withstand the test of time (Fresen, 2018). Since, system quality is significantly influence to perceived ease of use and perceived usefulness, the educational institution should endeavour to provide a conducive environment or facilitating conditions for the use of blended learning tools in the case of usage of these tools in a face – to – face classroom and quality internet services for online classes (Davies, 1986; Marriot et al., 2004)
The result obtained from the study has several implications as stated earlier. It will enhance educational institutions, educational partners, facilitators, education agency of government and policy makers. The education institutions will have to create enabling classroom environment and quality blended learning tools which gives the facilitators the privilege to interact well with the learners and the subject matter without abrupt alteration of the lesson processes/procedures. The institutions will have to engage the teachers in professional development to enable them to have confidence in using and carefully handling provided blended learning tools during teaching. In most cases, the application of blended learning tools will enhance deep learning by the students rather than surface learning through traditional teaching method because learners are the major focus in the education system. It will motivate education partners and donating institutions to liase with the institutions to provide quality blended learning tools needed within their system. Some institutions can engage in private – public partnership. This partnership allows the private organizations to salvage higher institutions to meeting up with the technological need in the classroom.
Limitations
This study is limited in terms of the number of sample/participants from the few selected technical vocational education and training institutions in Nigeria. First, the result could not be generalized because of the nature of the programme as it involves the inclusion of practical skill, values and morales into general education (Malamud and Pop-Eleches, 2010). Secondly, the outcome of the study could not be generalized among TVET institutions since the study was carried out in a developing country. The factor (policy, environment, availability of blended learning tools and exposure of students) that inhibits or enhance the adoption and usage of blended learning tools in developing is different from developed countries. Also, the level of technology advancement in developed countries could not allow the result to be generalized. Most developed countries have free access to internet connectivity and quality blended learning tools unlike underdeveloped and developing countries that battles unavailable and/or poor internet facilities, deficient experts to use blended learning tools, inadequate support services, inconsistent power supply, poor management system (Busulwa and Bbuye, 2017; Orji et al., 2021).
Conclusion
This study contributed immensely to the robustness of combined – TAM – TPB model to adopt blended learning tools. In theoretical perspective, the study showed that the consideration of quality blended learning tools with C – TAM – TPB model, will motivate the learners to accept, use and willing to continue using any form of blended tools integrated into the education institution. In this light, students will be desirous to use more complex learning tools to facilitate learning. The result showed a strong relationship between the quality of blended learning tools, technology acceptance constructs and the constructs of theory of planned behaviour. There is also a strong mediation effect between the TAM but not the TPB constructs. Likewise, there is a mediation effect between system quality and the relationship between perceived ease of use and perceived usefulness, perceived usefulness and attitude which implies that quality blended learning tools will propel student perception of the ease of use, perceived usability that will boost their attitude towards actual usage of such tools in educational institutions. Therefore, educational institutions should strive to provide quality blended learning tools to learners and instructors to enhance positive change in behaviour and academic excellence as a result of actual and continuous usage of such tools.
