Development and Evaluation of Hydro-pneumatic Power Brake System Trainer

Publisher: Bicol University
Abstract

Effective instructional materials can empower students by improving skills and concepts through multiple representations and enhanced visualization. It can also engage students in higher-order thinking, builds strong problem-solving skills, and develops a deep understanding of concepts and procedures when properly used. Hence, the researchers developed an automotive hydro-pneumatic power brake system and evaluated its effectiveness as an instructional device through the research and development (R&D) process. The finished product was presented to purposively selected respondents to assess its level of acceptability. After this, it was utilized in an actual teaching-learning (T-L) process to determine its effectiveness as an instructional device versus the traditional approach of instruction. The design of a trainer was a simulation of a real hydro-pneumatic power brake system used widely in most automobile nowadays. It was constructed using actual components to focus primarily on the purpose, operation, construction, and servicing of a brake system. It was supported by a manual of operation that facilitated the teaching-learning on this particular subject matter. The result of the evaluation of the effectiveness of the hydro-pneumatic power brake system trainer showed that there is a significant difference between the performance of the control group and the experimental group. Hence, the trainer is an effective instructional material that significantly improved the T-L process. It is recommended that institutions offering automotive technology courses should provide instructional devices to improve performances and consider design calculation if there are standard measurements to serve as basis in using the size or dimension of such material.
