<br/><br/> There is a growing need to enhance how practical competencies are taught in<br/>basic electricity, as traditional instructional methods often fall short in engaging students<br/>and developing essential hands-on skills. This study explores the potential of a newly<br/>designed PVC conduit bender as an instructional tool to enhance students’ practical<br/>learning experiences. Using the Design-Based Research (DBR) framework, the<br/>researchers aimed to design, develop, and evaluate the tool among 3rd and 4th Year<br/>BSIE students at the Technological University of the Philippines – Manila.<br/>In the first phase, Analysis of Practical Problems, the study identified the specific<br/>difficulties students encounter when bending PVC conduits during electrical laboratory<br/>sessions, revealing the inadequacy of current instructional methods. The second phase,<br/>Design and Development, led to the creation of a PVC conduit bender that integrates<br/>practical bending exercises with theoretical instruction. The third phase, Iterative Testing<br/>and Refinement, showed positive results in terms of the functionality and accessibility of<br/>the product. In the fourth phase, Derivation of Design Principles, key guidelines were<br/>formulated to inform the development of future instructional tools in technical education,<br/>particularly in bending PVC conduit.<br/>The findings confirm that the PVC conduit bender enhances students’ hands-on<br/>learning and engagement in laboratory classes. The study recommends further<br/>refinements, particularly in improving the heating element and bending accuracy, to<br/>maximize its instructional impact.
