Development of a Teaching Package for Learning Activities through an Electrical Appliance Repair Skill Training Kit

Abstract

     This research aimed to: 1) develop a teaching package for learning activities using a skill training set for electrical appliance repair in the subject “Electrical Appliance Repair” (Code: 20104-2110) under the 2019 Vocational Certificate Curriculum in Industrial Technology, targeting an efficiency of 80/80, 2) compare students’ learning achievement before and after using the package, 3) determine the effectiveness index, aiming above 0.50, and 4) study student satisfaction. The sample consisted of 25 second-year Electrical Power students selected through purposive sampling in the second semester of the 2023 academic year. Research tools included the teaching package, lesson plans, a quality assessment form, an achievement test, and a satisfaction questionnaire. Data analysis involved percentage, mean, standard deviation, and t-test.

     The results showed that the developed teaching package was rated at the highest quality level. The overall efficiency was 80.51/81.20, meeting the 80/80 criterion. Students’ post-test scores were significantly higher than pre-test scores at the .01 level, indicating improved achievement. The effectiveness index was 0.6225, reflecting a learning progress rate of 62.25%, exceeding the standard of 0.50. Student satisfaction toward the learning activities was rated at a high level, confirming the teaching package's quality and its effectiveness in promoting learning in the industrial technology field.
