Child Language Teaching and Therapy

Profound hearing loss can have serious and irreversible consequences for oral language development in children, affecting spoken and written language acquisition. Auditory-verbal therapy has been widely applied to children with hearing loss with promising results, mainly in developed countries where cochlear implants are available. An evaluation was done of auditory perception in 25 children 5 to 8 years of age, with profound hearing loss, users of 4- or 5-channel hearing aids, and enrolled in a personalized auditory-verbal therapy program. Regarding initial auditory perception skills, children performed better on the Noises and Sounds block than on the Language block. By subscales, top performance was observed for auditory analysis (Noises and Sounds) and auditory recognition (Language). A series of t-tests showed that significant improvement after Auditory-verbal therapy occurred in global scores for Noises and Sounds and for Language blocks, regardless of sex, urban or rural community origin, nuclear or extended family. The study provides evidence of deficiencies in auditory in children with profound bilateral hearing loss and how this might improve after receiving Auditory-verbal therapy. Nevertheless, the descriptive study design prevents conclusions regarding the effectiveness of the therapy. Subsequent research must take into account intrinsic and environmental factors that might play a mediating role in the benefits of Auditory-verbal therapy for auditory perception.

This experimental study aimed to influence reading comprehension skills through the development of one or both components of the Simple View of Reading (decoding and listening comprehension), by using a differentiated instruction approach. Reading comprehension skill gains were compared in an intervention group versus a control, after the delivery of a program designed to target one or both of such components. Fifty-four children from two 1st grade classrooms in a public school in Mexico were screened for difficulties in decoding and listening comprehension at the end of the school year. At the beginning of 2nd grade, 27 students identified with difficulties were randomly assigned to either an intervention (n = 14) or a control group (n = 13). Students selected for the targeted intervention attended the sessions aimed at their specific needs: five students with poor decoding only received the Phonological and Orthographic Awareness sessions of the intervention (9 sessions); seven students with poor listening comprehension only attended the Oral Vocabulary sessions (5 sessions); two students with mixed difficulties attended the full program (14 sessions). A 2 × 2 mixed analysis of variance showed that the interaction between the Time and Group variables had a significant effect, i.e. students in the intervention group had significantly higher scores in the post-test evaluation with respect to their baseline and compared to the growth observed in the control group. Results are discussed concerning their implications for teaching practices and for the use of strategies that target reading specific difficulties in students using both oral and written language.

Enhanced Conversational Recast (ECR) is an input-based grammatical intervention approach developed from research on statistical learning. Recent research reported evidence demonstrating the efficacy of ECR on the learning of grammatically obligatory morphemes in English-speaking preschool children with developmental language disorder (DLD). This single-case experimental design study, which adopted a within-participant design with single baseline and control item, investigated the efficacy of ECR in promoting the learning of aspect markers in four Cantonese-speaking typically-developing preschool children. Two children demonstrated positive outcomes with the progressive aspect marker ‘gan2’ given 12 ECR training sessions within a mean dosage of 288. One of these children demonstrated statistically significant gains in the percentage of correct use in the probes. The lack of positive outcomes in the other two children on the earlier developing aspect marker ‘zo2’ and limitations of the study were discussed. With early evidence established in the typically developing children in this study, future research on Cantonese speaking children with DLD can be considered.

Inferencing abilities are crucial to development of reading comprehension. However, few studies addressed those abilities in interventions promoting early literacy skills, especially in kindergartners. The aim of this study was to measure the efficacy of an interactive book-reading intervention targeting inferencing abilities, delivered by a school-based speech-language pathologist (SLP) in whole group kindergarten classes. Two hundred and forty-nine 5-year-old kindergartners from low socio-economic settings were quasi-randomly assigned to either one of the experimental groups (EG1 and EG2) or an active control group (CG). EG1 received a 7-week interactive book-reading intervention followed by a 7-week period where it was up to the teachers to implement aspects of the intervention in their teaching or not. EG2 received the 7-week interactive book-reading intervention only and the active control group received an initial workshop only. Three subtests targeting (1) causal inferences during book-reading, (2) causal inferences in a formal task, and (3) referential inferences in a formal task were performed at pre- and post-intervention assessments. There was a significant Time × Group interaction effect for the first subtest indicating an advantage for EG1 compared to CG over time. EG2 appeared as an intermediary group as its results were not different from EG1 and showing only a trend toward significance (p = 0.064) when compared to CG. There was no significant Time × Group interaction effect for the second subtest. A significant Time × Group interaction effect was present for the third subtest, EG1 and EG2 showing larger improvement than CG.

Interventions designed to improve communication environments and the quality of adult–child interactions in early years (EY) settings are an important part of facilitating children’s communication skills both for children with identified Speech, Language and Communication Needs (SLCN) and children without SLCN. One such intervention devised and delivered by speech and language therapists (SLTs) in Nottinghamshire is the Language Lead Approach (LLA), where SLTs deliver a formalized but flexible package of support and training to EY practitioners who go on to become Language Leads (LLs) for their setting. Nine SLTs delivering the LLA were interviewed to explore their perspectives on the implementation and impacts of the LLA. Interviews were analysed thematically. Three key themes were identified, the first of which related to factors internal to the setting and included aspects relating to the nature of initial and sustained engagement with an LL and the setting manager, time pressures and the impact of different setting organizational cultures. The second theme which emerged related to the individual qualities and characteristics of the LL, as SLTs noted that the response of LLs to the role varied considerably and was influenced by their confidence, experience and leadership capacity, as well as the degree of autonomy in the role. The final theme, external influences on implementation, reflected the SLTs own working practices and workload. Overall, SLTs felt the LLA was effective and could be implemented alongside their daily workload. SLTs reflected on their lack of training to implement such interventions, the challenges to sustaining the LLA at the setting and County level, and the challenges of evidencing effectiveness. This research has implications for those designing and evaluating training and mentoring approaches as well as for those SLTs who are seeking to develop the effectiveness of their consultative working with Early Years Educators (EYEs).

This study examined how intervention dose frequency affects phonological acquisition and generalization in preschool children with speech sound disorders (SSD). Using a multiple-baseline, single-participants experimental design, eight English-speaking children with SSD (4;0 to 5;6) were split into two dose frequency conditions (4 children/condition) targeting word-initial complex singleton phonemes: /ɹ l ʧ/. All children received twenty 50-minute sessions that were either provided twice a week (2×/week) for ten weeks or four times a week (4×/week) for five weeks. Tau-U effect sizes for two generalization measures, treated phoneme and percent consonants correct (PCC), were calculated for each participant. Group d-scores were calculated to measure generalization of the treated phoneme in untreated words for each condition. All eight children demonstrated gains in their phonological measures. Two children in 2×/week condition demonstrated significant changes in generalization of treated phonemes in untreated words. One child in each condition demonstrated significant changes in PCC scores. Group d-scores were similar suggesting children in both conditions generalized their treated phoneme in untreated words to a similar level. Regardless of whether speech intervention occurred 2×/week or 4×/week, children demonstrated similar phonological gains. This suggests that both dose frequencies are viable intervention schedules for preschoolers with SSD. Children in the 4×/week condition made their phonological gains in approximately half the time of children in the 2×/week condition. Thus, more frequent weekly speech intervention sessions could be more efficient in teaching phonological information than less frequent sessions.
