The objective of this study is to construct and find the efficiency of a portable electrical wiring tube trial kit and to explore the satisfaction level of learners toward the learning process. The sample group of this study is the 40 2nd year vocational students at the certificate level who are enrolled in the electrical power department at the Chachoengsao technical college. Using the purposive sampling method, the instruments utilized include the mentioned portable electrical wiring tube trial kits, seven variations of worksheets, and pre-post examination, and the class would take 126 hours. We must find the average, percentage, standard deviation, and effectiveness of E1/E2 to analyze the data. The result found that the kit's effectiveness is measured at 85.46/82.81, which is higher than the initial standard, which is 80/80. Therefore, we can conclude that the kit can effectively be used as a teaching tool.
