Improvised Heat Treatment Equipment: A Package for Technology Instruction

Abstract

Improvised heat treatment equipment: A package for technology instruction was intentionally designed and used for an actual laboratory facility in the BIT- MST (Bachelor of Science in Industrial Technology major in Machine Shop Technology) at the Tuburan Campus. It was intentionally constructed due to the unavailability of the equipment in the laboratory. All parts assembled were bought from junk shops. The laboratory test of the equipment was successfully conducted.   The study assessed the conditions of the product as a basis for a package instructional model in the heat treatment subject course. Specifically, it determined (1) the profile of the students and instructors. (2)  Time attainability of the heat treatment metals in relevance to required temperature when conducting annealing, Hardening, and tempering; (3) level of acceptability of the Improvised heat treatment equipment; (4) Problems met by the respondents (instructors) during operation for quality performance enhancement; (5) Proposed heat treatment equipment for the instructional model. The study utilized both quantitative and qualitative methods. The descriptive, evaluative research design used survey questionnaires on the profiles of the respondents, both students and instructors. The quantitative method was also used to determine standard time after reaching the required temperature in heat treatment operations based on the color chart of metal heated at the corresponding temperature during transformation. The equipment was developed on an experimental basis at three attempts. The equipment was fabricated for quality improvement based on suggestions given by expert instructors. There was evidence that the improvised heat treatment equipment: a package for technology instruction must be adopted.
