A Study on Learning Achievement through Knowledge Construction Techniques using an Instructional Package on Standardized Welding Positions

Abstract

This research employed a combination of research and development (R&D) and experimental research methodologies. The objectives were 1) to develop a Instructional Package on welding positions according to welding standards using the 3W1H principle; 2) to evaluate the quality of the developed Instructional Package; and 3) to examine students’ learning achievement through the use of knowledge construction and comprehension techniques integrated into the teaching kit on welding positions. The sample group was specifically selected and consisted of 15 third-year undergraduate students majoring in Industrial Education at the Faculty of Industrial Education, Rajamangala University of Technology Isan, Khon Kaen Campus, during the second semester of the 2024 academic year. The research instruments included the teaching kit on welding positions based on welding standards, an expert-based quality assessment form (5 experts), and a pre-test and post-test achievement assessment. Data analysis involved percentage, mean, standard deviation, and t-test statistics. The results revealed that the Instructional Package consisted of 1) content modules; 2) instructional media including slides and 3D teaching models; 3) learning achievement tests; and 4) an instructional guide for facilitating knowledge and understanding. The overall quality of the Instructional Package was rated at a high level (𝑥̄ = 3.98, S.D. = 0.23). Furthermore, the study found that students' post-test scores (mean = 25.33) were significantly higher than their pre-test scores (mean = 11.40) at the .05 significance level (Sig. = .00), indicating that the developed Instructional Package effectively enhanced students’ learning achievement.
