The Development of a Learning Activity Package for Mechanical Laboratory (Course Code 30101-2007) Based on the 7-Step Learning Cycle (7E) Integrated with Laboratory Method Learning for Higher Vocational Certificate Students in Mechanical Technology

Abstract

This research aimed to: (1) study basic information and assess the needs for developing a learning activity package; (2) develop and determine its effectiveness; (3) implement the package; and (4) evaluate and revise it. The study followed a research and development (R&D) methodology. The target group consisted of 20 second-year diploma students in Mechanical Technology at Nakhon Ratchasima Technical College during the second semester of the 2024 academic year. Research tools included a needs questionnaire, an interview form, four sets of activity packages, and evaluation forms for content suitability, lesson plan quality, group work behavior, and student satisfaction. Data were analyzed using percentage, mean, standard deviation, and t-test.

The research yielded several key findings: (1) activity package development should connect theory with practical application, and (2) its overall appropriateness was rated at the highest level. (3) Experimental use of the activity package showed: (3.1) effectiveness test results (E1/E2) of 82.70/81.41 and an Effectiveness Index (E.I.) of 0.62, and (3.2) students' post-test learning achievement was significantly higher than pre-test scores at the 0.05 statistical level. Finally, (4) activity package evaluation and improvement revealed: (4.1) students' group work behavior was assessed at the highest level, (4.2) their satisfaction with the package was also at the highest level, and (4.3) illustrations detailing the experimental procedures were revised for clarity and alignment with the content.
