The Development of a Skill Training Kit for Solar Power Circuits for the Electrical Power Program at Lampang Technical College

Abstract

The objectives of this study were to 1) develop and evaluate the efficiency of a solar power circuit skill training kit for the Department of Electrical Power, Lampang Technical College, and 2) compare the students’ learning achievement before and after using the solar power circuit skill training kit for the Department of Electrical Power, Lampang Technical College. In the 1st year vocational certificate of Electrical Power, Lampang Technical College, Semester 1, Academic Year 2023, 41 students were obtained by simple random draw. The tools used in the research include 1)  Solar energy circuit skill training set that has been inspected for quality by experts and has an average of 4.71. 2) The pre- and post-tests had content validity index (IOC) values ​​ranging from 0.67-1.00 and a reliability of 0.89 which data were analyzed using arithmetic mean, standard deviation, E₁/E₂ efficiency, and cluster t-test. The results showed that: 1) the developed solar power circuit skill training kit consists of 4 important components: the skill training kit, the pre-and post-class tests, the teaching materials, and the solar power circuit skill training kit, 2) the trial was used, it was found that the process efficiency (E₁)/result efficiency (E₂) was 82.08/79.51, which is equal to the 80/80 criterion, and 3) when comparing the academic achievement results, it was found that the learners scored higher after the course than before the class with statistical significance at the .01 level it was found that the learners scored higher after the course than before the class. The key findings are that learners who have studied electrical circuits can connect the electrical circuits of the skill training kit more efficiently should be added to the electrical installation course curriculum in the electrical  power department.
