{"abstract":"The electronics industry faces challenges such as insufficient instructional materials and limited access to relevant teaching tools, demonstrations, and hands-on lab exercises, all of which are crucial for enhancing electronics education for both educators and students. The increasing enrollment of electronics students and rapid technological advancements prompted the researcher to develop concrete and tangible devices for electronics education. This study aimed to develop and evaluate an LED Television Trainer as a supplemental teaching aid in electronics technology. The trainer was designed and developed using the developmental research method and assessed through a descriptive-evaluative approach. Sixty participants, comprising students, TLE teachers, and technicians from various electronics shops and service centers, evaluated the trainer's design and construction, durability, safety, functionality, and instructional applicability through surveys and experiments. The evaluation results demonstrated high acceptability across all criteria, with respondents consistently providing positive feedback that highlighted the trainer's effectiveness and efficiency in facilitating the learning and practical application of LED television technology. This strong endorsement underscores the trainer's potential to enhance educational outcomes, addressing the challenges of insufficient instructional materials and limited access to electronic tools. The study concludes that the LED Television Trainer prototype exemplifies how such innovations can positively transform learning experiences, equipping students with practical skills and knowledge that extend beyond the classroom to meet industry demands.","abstract_source":"original","authors":["Edilberto Bayang","John Paul Cubangbang"],"date":"2024-10-24","doi":"10.5281/zenodo.13983513","id":3752,"issue":1,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"d268c9d6abb390026ce3caade8811ec214d28a32b422e878b7030b47b50bab6d","schema":"scimatic-article/1","title":"Development and Evaluation of LED Television Trainer","volume":27}
