The Development of a Training Set for Maintenance of Small 4-stroke Gasoline Engines Combined with Blended Learning to Enhance Operational Skills for Students in the Vocational Certificate Level in Automotive Mechanics Branch

Abstract

This research aimed to: 1) develop and assess the effectiveness of a training set of small 4-stroke gasoline engines combined with blended learning to enhance operational skills, 2) compare the operational skills of students trained with the training set of small 4-stroke gasoline engines combined with blended learning against the established criteria. The sample group consisted of 20 second-year students majoring in automotive engineering at Krabi Technical College selected through group random sampling. The research tools included: 1) a record form on teaching management issues, 2) a skill training set, 3) an appropriateness evaluation form, and 4) an operational behavior observation checklist. The data were analyzed by content analysis, mean, standard deviation, and t-test.

The research findings revealed that 1) the appropriateness of the training set of small 4-stroke gasoline engines combined with blended learning was overall at the highest level. The effectiveness of the training set of small 4-stroke gasoline engines exceeded the set criterion of 80/80. Additionally, 2) the comparison of students' academic achievement after using the training set of small 4-stroke gasoline engines was significantly higher than the 80% criterion with the statistical significance at the .05 level.
