The Development of Turning Skill Training Sets Based on the MIAP Learning Approach: A Case Study in Machine Tool Practice Courses for Undergraduate Students

Abstract

This research aimed 1) to develop a skill training kit for the Machine Tool Practice course focusing on turning operations, 2) to evaluate the efficiency of the training kit based on the 80/80 criterion, and 3) to compare the learning achievement of students using the training kit with the 80% benchmark. The sample consisted of 30 first-year students from the Department of Production and Industrial Engineering, the Faculty of Industrial Education and Technology, King Mongkut's University of Technology North Bangkok. The sample was selected through cluster random sampling from a population of 384 students. The experiment was conducted over eight weeks. The research instruments included: 1) a turning skill training kit, 2) a behavior observation form, 3) a practical skill assessment, and 4) a training kit suitability evaluation form, which was validated by experts with an Item-Objective Congruence (IOC) index ranging from 0.60 to 1.00. Data were analyzed using percentage, mean, standard deviation, and t-test. The research findings revealed that 1) the developed training kit was rated as highly suitable (=4.73, S.D.=0.03), 2) the training kit demonstrated an efficiency of 87.11/88.93, exceeding the specified criterion, and 3) students’ learning achievement was significantly higher than the 80% benchmark at a 0.05 level of significance (t=4.07)
