Abstract
The objective of this research is to develop and test the effectiveness of an electrical power system Instructional Package, as well as to improve power factor using MATLAB GUI, for vocational certificate students. Additionally, it aims to study the satisfaction of learners towards the electrical power system Instructional Package and the improvement of power factor using MATLAB GUI. The developed Instructional Package comprises a learning management plan, content, practice sheets, PowerPoint presentations, MATLAB GUI function simulation programs, RLC circuit training kits, post-learning assessment forms, and efficiency measurement assessments. The research sample group consists of 20 vocational certificate students from Phrae Technical College enrolled in the Electrical AC Circuit course, 1st year, academic year 2023.
The research findings indicate that the developed Instructional Package is effective, with a score of 78.00/77.33, meeting the established criterion of 75/75. Moreover, the assessment of learner satisfaction with the developed Instructional Package reveals a high level of satisfaction, with an average score of 4.39 and standard deviation of 0.59. Therefore, the development of the electrical power system Instructional Package and improvement of the power factor using MATLAB GUI for vocational certificate students are deemed highly effective for instructional purposes.
