Development and Optimization of Teaching Set on Workpiece Sorting using Automatic Control System การสร้างและหาประสิทธิภาพชุดการสอนเรื่องการคัดแยกชิ้นงานด้วยระบบควบคุมอัตโนมัติ

Abstract

This research aimed to create and find the efficiency of teaching kits. The research instruments were quality assessment form and teaching kits. The sample groups used in the research consisted of 2 groups: 15 experts with knowledge, expertise, and experience in automatic control systems for at least 5 years, with at least a master's degree, and 15 students in Mechatronics and Robotics Technology of Minburi Technical College, using purposive selection. The statistics used for analysis were mean, standard deviation, and t-test for dependent samples.
The results of the research found that the creation of an experimental teaching media set on workpiece sorting using an automatic control system and a servo motor system working in conjunction with a pneumatic system and programming controlled by a PLC device, from the evaluation of the quality of the teaching kits by experts, had a mean score of 4.59, which was considered very good. The standard deviation was 0.27, which was slightly different. The results of the experiment on the difficulty level of the test used with the experimental group of students, P = 0.52, which was at a moderate level of difficulty. The results of the discrimination power of the test, R = 0.64, which was considered a fairly good test, but may need some improvement. And when it was tested to analyze the effectiveness of the teaching kits, comparing scores between the study and after the study, the effectiveness of the teaching set was 90.50/82.62, which was higher than the set criteria of 80/80, indicating that students had more knowledge and understanding after studying with this teaching kits.
