Abstract

Background and Aims: Education is an important foundation for developing human resources to enable them to live and work with quality in a rapidly changing society, the current education system therefore focuses on learner-centered learning, providing skills, knowledge, and morality, especially in vocational education, which must emphasize practical training to prepare for the labor market, therefore, the development of teaching media that promotes learning and practical skills is essential. This research aims to 1) compare the learning achievement in the Automotive Power Transmission course and 2) compare students’ satisfaction with learning in the Automotive Power Transmission course between students taught using an instructional package and those taught using conventional methods.

Methodology: The study was conducted with first-year vocational certificate students at Bangnara Technical College. The sample consisted of 28 students, divided into an experimental group (taught using the instructional package) and a control group (taught using conventional methods), with 14 students in each group. The participants, selected through simple random sampling, consisted of 30 vocational certificate students. The research instruments included a learning achievement test and a satisfaction questionnaire for the Automotive Power Transmission course. Data were analyzed using mean and one-way multivariate analysis of variance (One-way MANOVA).

Results: The research results found that 1)   The comparison of learning achievement in the Automotive Power Transmission course between first-year vocational certificate students at Bangnara Technical College who were taught using the instructional package and those who received conventional instruction showed that the students taught with the instructional package had significantly higher learning achievement than those taught by traditional methods, at the .01 level of significance. 2) The comparison of learning achievement and satisfaction in the Automotive Power Transmission course between first-year vocational certificate students at Bangnara Technical College who were taught using the instructional package and those who received conventional instruction indicated that both the learning achievement and learning satisfaction of students taught with the instructional package were significantly higher than those taught with conventional methods at the .01 level of significance, and 3)        The analysis of student satisfaction with the Automotive Power Transmission course among first-year vocational certificate students at Bangnara Technical College revealed that the overall and specific aspects of satisfaction were at the highest level. The highest-rated aspects included knowledge acquisition, skill development, and moral and ethical values, particularly the integration of the Sufficiency Economy Philosophy.

Conclusion: The research results indicated that the use of teaching kits resulted in significantly higher academic achievement in the subject of Automotive Power Transmission of the first year vocational certificate students at Bangnara Technical College than the conventional teaching method. Students who studied with the teaching kit had higher achievement and satisfaction than the group who studied with the normal method.
