Development of learning activity module on topic stress in material using finite element method for higher vocational certificate students in mechanical engineering
Abstract:
The analysis and resolution of engineering problems today involve material stress theory and computer-aided design using the Finite Element Method (FEM) to simulate material behavior before and after deformation. Results are presented with numerical values and color coding to enhance students' understanding. This research aims to: 1) develop and evaluate the effectiveness of a learning activity package on material stress using FEM to improve learning outcomes for Higher Vocational Certificate students in Mechanical Engineering; and 2) compare the learning outcomes of students using the FEM-based material stress package with the established criteria. Tools used include: 1) the learning activity package, 2) an evaluation of its suitability, and 3) a test to measure students' outcomes. The sample consisted of 20 students from Ang Thong Technical College in the second semester of the 2024 academic year, selected by Cluster Random Sampling. Statistical methods such as percentage, mean, standard deviation, and T-test for one sample were used. Results showed: 1) the activity package was highly suitable, with a mean of 4.63 and a standard deviation of 0.06. Student scores during the activity (E1) were 80.00%, and after the activity (E2) were 85.16%; and 2) students' learning outcomes were significantly higher than the established criteria at the 0.05 significance level.
