Improving Teaching and Learning Outcomes Using Video Media for Differential Gear in Automotive Power Transmission Course

Abstract

This research aimed to achieve three objectives: 1) To develop video media for teaching and learning on Differential Gear in the Automotive Power Transmission Course, ensuring its effectiveness meets the 80/80 criterion. 2) To enhance disassembly and assembly skills of differential gears by comparing learning achievement before and after using the video media for instruction on Differential Gear in the Automotive Power Transmission Course. 3) To investigate students' satisfaction with learning through the video media on Differential Gear in the Automotive Power Transmission Course. The research sample consisted of 16 vocational certificate students, 2nd year, Group 3, in the Automotive Power Transmission Course, Automotive Technology Department, Suphan Buri Technical College, during the second semester of the academic year 2023. The sample was selected using purposive sampling. The research instruments included: Video media for teaching and learning on Differential Gear in the Automotive Power Transmission Course. A performance skill assessment form for differential gear disassembly and assembly in the Automotive Power Transmission Course, used to compare practical skill achievement. A student satisfaction questionnaire regarding learning with video media on Differential Gear in the Automotive Power Transmission Course. The statistical analyses used were arithmetic mean, standard deviation, and t-test for dependent samples to test hypotheses. The research findings revealed: 1) The effectiveness of the video media for teaching and learning on Differential Gear in the Automotive Power Transmission Course showed process efficiency (E1) of 82.69 and product efficiency (E2) of 87.13 (E1/E2 = 82.69/87.13), which is higher than the set criterion of 80/80. 2) Students who learned using the video media on Differential Gear in the Automotive Power Transmission Course had post-learning disassembly and assembly skills for differential gears significantly higher than pre-learning skills at a statistical significance level of 0.01. 3) Students expressed the highest level of satisfaction with the video media for teaching and learning on Differential Gear in the Automotive Power Transmission Course.
