The Development of The EM 09-11 Electrical Machinery Competency Training Set for Vocational Education

Abstract

This research article aims to (1) develop and evaluate the effectiveness of the EM 09 – 11 Electrical Machinery Competency Training Set, (2) compare the learning achievements of students using the EM 09 – 11 Electrical Machinery Competency Training Set with those using traditional learning methods, (3) compare the students’ post-learning competency scores obtained through the use of the Electrical Machinery Competency Training Set (Panels EM 09–11) with the criterion level of 60 percent, and (4) study the satisfaction of students using the EM 09 – 11 Electrical Machinery Competency Training Set. This research is a quasi-experimental study that employs the 4D Model concept as the framework. The sample group consisted of students from the Electrical Department of Nakhon Si Thammarat Technical College, Semester 2, Academic Year 2024, obtained through cluster random sampling, divided into an experimental group of 21 individuals and a control group of 14 individuals. The tools used for data collection included achievement tests and satisfaction questionnaires. The statistics used for data analysis included percentages, means, standard deviations, and t-tests for independent samples. The study found that 1) the analysis of expert opinions on the EM 09 – 11 Electrical Machinery Competency Training Set showed a high average level (M = 4.45, S.D. = 0.44). The performance test results met the requirements with 100% compliance, and the average process score to average outcome score ratio of students who learned using the EM 09 – 11 Electrical Machinery Competency Training Set was 81.59/80.58, meeting the set criteria of 80/80. 2) The post-test mean score of students who learned with the EM 09-11 set was significantly higher than that of those taught through traditional methods at the .05 level of significance. 3) The competency scores of students in the experimental group after the learning intervention were significantly higher than the criterion level of 60 percent at the .05 level of significance. 4) The satisfaction level of students who learned with the EM 09 – 11 Electrical Machinery Competency Training Set was at a high level (M = 4.49, S.D. = 0.56).
