Simplified Electrical Wiring Installation System (SEWIS) Board and Its Effect on SHS Tech-Voc Students' Perception, Academic Performance, and EIM NC II Assessment Passing Rate

Abstract

INTRODUCTION

The Simplified Electrical Wiring Installation System (SEWIS) Board, is an intervention facility used to provide an INTRODUCTION to electrical wiring techniques. It faithfully reproduces a residential environment where students can develop their skills in the installation and wiring of residential electrical equipment. The knowledge and skills students gain from these activities will enable them to identify and demonstrate proper wiring of common electrical fixtures, as well as the skills to wire some of the most common electrical circuits. The system can also be used to teach how to adjust and maintain electrical equipment, as well as enforce the safety rules to be followed when working.

METHODS

Mixed method of research was employed in this study. Quasi-experimental design was used in determining the significant effect of using SEWIS board on the academic performance of 46 purposively-selected EIM NC II students of Calamba Bayside IS for SY 2017-2018. Pre-posttest was used as instrument and t-test was used to treat the data. Qualitative design was employed in determining the perception of students on using SEWIS board and thematic approach was used in data analysis.

RESULTS

The study revealed a significant difference between the respondents' pre-test and post test scores during the SY 2017-2018, which indicated an improvement in their academic performance. Based on the thematic analysis, all respondents (100%) strongly agreed that SEWIS board was helpful to easily understand how electrical circuit works; SEWIS board was easy to manipulate; and helped in preparation for EIM NC II assessment. Likewise, 100% passing rate was attained during the March 2018 Assessment, which proved that using SEWIS board was effective in preparing students for assessment.

DISCUSSIONS

Due to its modular design, SEWIS BOARD can be configured to fit various training needs. A versatile, mobile workstation is the basis of the system. As students learn more about electricity and wiring, they will become more confident and would serve as their first step towards a successful career as electricians.
