Development And Evaluation Of AC/DC Basic Electronics And Electrical Circuit Connection Trainer

Abstract

The study was focused on the development and evaluation of the AC/DC Basic Electronics and
Electrical Circuit Connection Trainer for the students of Isabela State university-City of Ilagan Campus,
City of Ilagan, Isabela. This project development research tried to achieve the following objectives: a)
Design and construct AC/DC Basic Electronics and Electrical Circuit Connection Trainer; b) Test the
functionality of the trainer by conducting various experiments concerning practical basic electronic and
electrical circuits through the application of series, parallel and complex connections; c) Determine the
acceptability of the prototype in terms of its functionality, workability, durability, safety and instructional
applicability as evaluated by the respondents; and d) Make an activity manual that can be used from a
developed trainer.
The five-point Likert’s scale was used to determine the descriptive meaning of the indicators of the variables
used. Furthermore, the Weighted Average Mean (WAM) was used to interpret the equivalent meaning of the
data gathered. The Analysis of Variance (ANOVA) was employed to determine the significant difference
between the evaluations of the respondents.
The completed project was evaluated by selected six (6) technology instructors, forty-one (41) students, one
(1) Electrician and two (2) IT technicians from Isabela State University-City of Ilagan Campus from the
Colleges of Engineering, Industrial Technology, College of Education, four (4) shop teachers from nearby
technical schools and two (2) technicians from electronics repair center in the locality.
Evaluation result shows that the project obtained an overall mean of 4.78 which means that the trainer is
“HIGHLY ACCEPTABLE” to the evaluators based on the criteria of functionality, aesthetics, workability,
durability, economy, safety and instructional applicability.
