Abstract
This research is to develop and construct the instructional package on RLC circuit of AC Circuits course using GUI function of MATLAB for Vocational Certificate. The constructed instructional package consists of three units including R, L, and C in AC circuit, R–L R-C in series circuit, and RLC in series circuit. The instructional package consists of the information sheet, the presentation program, the GUI function of MATLAB simulation program, RLC circuit tester, Post-test, and achievement test. The sample group was 20 Vocational Certificate students in the 1st year students of Curriculum for Certificate of Vocational Education in Electrical, Pathum Thani Technical College, that registered in second academic year 2022. Using a multi-stage sampling method and the statistics used for analyzing the data, there were efficiency (E1/E2), mean (), and standard deviation (SD). The results of the research found that the developed teaching package had an efficiency of 77.00/75.33, which was in accordance with the specified criteria 75/75. The results of the evaluation of student satisfaction with the developed teaching package were at a high level of satisfaction (average (
) equaled to = 4.30, Standard deviation (SD) equal to 0.74) according to the research hypothesis. Thus, the constructed instructional package on RLC circuit using GUI function of MATLAB for vocational certificate can be used in the teaching and used appropriately in learning and teaching of Vocational Education to encourage students for having knowledge and practical skills consistent as an expected leaning outcome of curriculum.
