Enhancing Learning Achievement in Industrial Chemistry for the First-Year High Vocational Certificate Students in Rubber Industrial Technology Using the Jigsaw Teaching Technique with the PhET Application

Abstract

This research aimed to 1) compare pre- and post-instructional learning achievement using the Jigsaw technique combined with the PhET application and 2) study student satisfaction with cooperative learning using the Jigsaw technique combined with the PhET application. The population and sample used in this research consisted of 23 first-year High Vocational Certificate students in the Rubber Industrial Technology program, Semester 1, Academic Year 2025, at Surat Thani Technical College. The sample was selected using purposive sampling. The research tools included a lesson plan for Industrial Chemistry for the first-year High Vocational Certificate students, an achievement test in Industrial Chemistry for the first-year High Vocational Certificate students, and a questionnaire on student satisfaction with cooperative learning using the Jigsaw technique combined with the PhET application. The statistics used for data analysis included content validity, difficulty level, discrimination index, and reliability coefficient. The descriptive statistics included the mean and standard deviation, and the dependent t-test. The research findings showed that 1) cooperative learning achievement using the jigsaw technique combined with the PhET application was significantly higher after the intervention than before, supporting the hypothesis at the 0.05 statistical significance level. The post-intervention mean (=24.65) was higher than the pre-intervention mean ( = 13.43). 2) The students' satisfaction towards collaborative learning using the jigsaw technique combined with the PhET application was at the highest level, with an average score () of 4.61 and a standard deviation (S.D.) of 0.08.
