YouTube Videos as Supplementary Materials to Enhance Computer Troubleshooting and Repair Techniques for Senior High School Students in the Philippines

This study aimed to improve learners' academic performance in Computer Troubleshooting and Repair Techniques at Lal-lo National High School by using YouTube videos with teacher-made learning activity sheets as supplementary materials. The study employed a quasi-experimental design, particularly a one-group pretest and posttest design, in which the intervention was administered to the same participants. The result proved that the learners gained a higher mean on their posttest result than their pretest, indicating a significant difference between the pretest and posttest scores. Moreover, the intervention greatly affected the students' academic performance, particularly on the competency in Computer Troubleshooting and Repair Techniques. YouTube videos can help visual learners, and students better understand a subject. These videos can catch students' imagination, especially when face-to-face learning is discouraged owing to the epidemic. The intervention material may be adapted by ICT, TLE teachers, and other disciplines.
