AN EXPERIMENTAL LEARNING KIT FOR ELECTRICAL CIRCUITS TO BE USED IN THE INSTRUCTION OF THE BASIC ELECTRICAL AND ELECTRONICS COURSE UNDER THE VOCATIONAL CERTIFICATE PROGRAM AT RAJAMANGALA UNIVERSITY OF TECHNOLOGY ISAN SAKON NAKHON CAMPUS

This research aimed to measure the learning effectiveness of students’ learning effectiveness using the electrical circuit laboratory experiment kit in the basic electrical and electronics engineering course, Vocational Certificate Program, at the Rajamangala University of Technology Isan, Sakon Nakhon campus. It also assessed students’ satisfaction with using this electrical circuit laboratory experiment kit. The population for this study comprised 20 first-year students majoring in Electrical Engineering, Vocational Certificate Program, Rajamangala University of Technology Isan, Sakon Nakhon campus. The research tools included the electrical circuit laboratory experiment kit for Basic Electrical and Electronics Engineering, Vocational Certificate Program, Rajamangala University of Technology Isan Sakon Nakhon campus, quality assessment forms for content and technical aspects of media production, performance measurement tests, practical performance evaluation forms, and satisfaction assessment forms. Statistical analysis utilized in data analysis included mean (equation), standard deviation (SD), the quality of the experimental training kit, percentage (%), and the E1/E2 ratio. The research findings revealed that the learning outcomes based on the electrical circuit laboratory experiment kit led to the discovery of methods to develop research tools in the aspect of the electrical circuit laboratory experiment kit to support teaching in the Basic Electrical and Electronics Engineering course, covering knowledge, attitudes, and skills as prescribed by the instructor. The content quality of the electrical circuit laboratory experiment kit was at a good level (equation = 3.67, SD = 0.58), while the technical media production quality was also at a good level (equation = 4.33, SD = 0.58). The efficiency was 78.6/82.1(E1/E2), meeting the specified criteria. Additionally, the students' satisfaction with the use of this electrical circuit laboratory experiment kit was at the highest level (equation = 4.54, SD = 0.42).
