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

Abstract

The objectives of this research were to: 1) develop a teaching package for learning activities using a skill training set for electrical appliance repair in the subject Electrical Appliance Repair (20104-2110) under the 2019 Vocational Certificate Curriculum in Industrial Technology to achieve an efficiency level of 80/80, 2) compare students' learning achievement before and after using the developed package, 3) determine the effectiveness index of the package, expecting it to exceed 0.50, and 4) study students’ satisfaction toward the learning activities. The sample group consisted of 25 second-year students from the Electrical Power Program, selected through purposive sampling during the second semester of the 2023 academic year. The research instruments included the teaching package, lesson plans, a quality assessment form, an achievement test, and a student satisfaction questionnaire. Data were analyzed using percentage, mean, standard deviation, and t-test.

The research findings revealed that the teaching package using the skill training set received a quality evaluation at the highest level. The overall efficiency was 80.51/81.20, meeting the 80/80 criterion. Students’ post-test scores were significantly higher than their pre-test scores at the .01 level, indicating improved academic achievement. The effectiveness index was 0.6225, representing a learning progress rate of 62.25%, exceeding the set criterion. Furthermore, students’ overall satisfaction with the learning activities was rated at a high level, indicating a positive attitude toward the teaching method. The results confirm that the developed package is effective and beneficial for learning in industrial technology.
