The effect of a video-guided educational technology intervention on the academic self-concept of adolescent students with hearing impairment: Implications for physical education.

Background/Objective: Academic self-concept is an important construct within the disciplines of medicine, psychology, and education. Enhancing the academic self-concept of students with special educational needs is very crucial because it is associated with their quality of life. This study aimed to examine the effect of a video-guided educational technology intervention on the academic self-concept of adolescents with hearing impairment who were attending inclusive nonresidential public schools in Southeast Nigeria. Methods: This study adopted a randomized controlled trial design. The participants were 60 junior secondary students with hearing impairment. We implemented a video-guided educational technology intervention. It relied on the use of 13-minute video clips with captions/subtitles, which covered academic self-concept-related themes. The Academic Self-Concept Questionnaire, which has been developed by Liu and Wang, was used to collect baseline, posttreatment, and follow-up data. We conducted independent-samples and pairedttest and computed Cohendand Glass Delta to analyze the data. Results: The video-guided educational technology intervention significantly improved the academic self-concept of the treatment group participants, when compared with the care-as-usual control group participants,t(58) = 9.07,P < .001. These improvements in academic self-concept were sustained at follow up among the treatment group participants, when compared with the care-as-usual control group participants,t(48.56) = 10.898,P Conclusion: The video-guided educational technology intervention was effective in improving the academic self-concept of adolescents with hearing impairment who were attending inclusive nonresidential public schools. Large-scale studies are needed to maximize the impact of video-guided educational technology interventions on students with hearing impairments who attend inclusive non residential public schools in Nigeria.
