Effects of Machine-based Instruction on the Technical Competencies of Welding and Fabrication Students at Palompon Institute of Technology

This study examined the effectiveness of machine-based instruction using a cassava slicing prototype in enhancing the technical competencies of welding and fabrication technology students in Palompon Institute of Technology. A quasi-experimental pretest–posttest control group design was employed involving 40 students divided equally into experimental and control groups. The experimental group received hands-on instruction using the machine prototype, while the control group was taught using conventional lecture-demonstration methods. Results showed that both groups significantly improved; however, the experimental group achieved higher posttest scores and greater mean gains. Independent sample t-test results revealed a statistically significant difference between the groups (p < 0.05), indicating the superiority of machine-based instruction. The findings suggest that integrating functional prototypes into instruction enhances cognitive and psychomotor competencies. This study supports the adoption of experiential, technology-integrated approaches to improve learning outcomes and workforce readiness in TVET.
