Design Fabrication and Testing of Auto electrical Accessory and Appliances Circuits Trainer

Abstract

The project aims to design and fabricate a modular automotive electrical mock-up to enhance student understanding of complex auto electrical systems.
This mock-up will provide effective instructional materials, focusing on safety, component identification, and troubleshooting various circuits. Additionally, it will
assess acceptability and effectiveness as an educational tool, catering to the needs of automotive technology programs in the Philippines.
The project employed a research and development (R&D) method to create and validate a modular automotive electrical system, following a systematic
process of planning, construction, testing, and revision. After completing the device, it was assessed for acceptability by automotive technology instructors and
students through a checklist questionnaire, and its effectiveness was evaluated using a pre- test and post-test design against existing instructional materials.
Statistical analyses, including weighted mean and t-tests, were used to interpret the gathered data and determine the mock-up's impact on learning outcomes.
The modular auto-electrical accessory device effectively integrates three key circuits—car stereo, alarm, and mobile phone charger—using a durable,
honeycomb-shaped design with color-coded connectors for easy identification. Constructed through a meticulous research and development process, the device
not only serves practical applications but also supports educational purposes, enhanced by a comprehensive instructional manual aligned with NC II standards.
Evaluation through pre-test and post- test comparisons showed significant improvements in learner understanding, confirming the device's effectiveness as an
instructional tool for automotive servicing.
To enhance the modular auto-electrical accessory device, suggestions include improving the instructional manual with more troubleshooting scenarios,
implementing user feedback mechanisms, and broadening testing with diverse sample groups. Proposed utilization activities involve organizing workshops for
educators, conducting hands-on demonstrations, and creating online resources to facilitate effective integration into automotive training programs. Additionally,
establishing collaborative partnerships and sharing case studies at conferences will promote wider adoption and continuous improvement of the device.
