Development of a Training Set for Maintenance Skills of Lathe Gear Transmission Systems Integrated with a Situated Learning Approach for Industrial Technician Students

Abstract

This research aimed to develop and evaluate the effectiveness of a training set for the maintenance skills of lathe gear transmission systems, integrated with situational learning activities for industrial technician students. Additionally, it sought to compare the practical skills of students who used the training set against predetermined benchmark criteria. The sample consisted of 20 students, selected using cluster random sampling. The research instruments included: 1) a problem and solution recording form for teaching and learning management, 2) a training set, 3) an appropriateness assessment form with content validity ranging from 0.60 to 1.00, and 4) a skill evaluation form with content validity ranging from 0.60 to 1.00 and inter-rater reliability of 0.70. Data analysis methods included content analysis, calculation of means, standard deviations, and t-tests. The findings revealed that students lacked sufficient maintenance skills for real-world scenarios, as well as knowledge of proper maintenance behavior and processes. Previously used instructional materials primarily presented basic maintenance principles, resulting in students' academic performance falling below the benchmark. To address these gaps, the researcher developed a training set based on a situational learning approach, which allowed students to practice analytical thinking and problem-solving within realistic contexts. The training set's overall appropriateness was rated at a very high level (  = 4.77, S.D. = 0.39). The training set's efficiency exceeded the specified benchmark standard of 80/80. Furthermore, the comparison of students' practical skills after using the training set demonstrated statistically significant improvements, with performance exceeding 80% at the .05 significance level.
