A significant aspect of modern life is electricity. The world would be substantially different without it. Electricity has become a necessity for humanity. This trainer board was designed in order to assist electrical technology teachers effectively teach the fundamentals of building wiring installation. It is anticipated to be simple to utilize, appropriate for students at their educational level, and responsive to current demands in building wiring installation. The respondents used in the evaluation of the trainer were 20 first-year Electrical Technology students of Bohol Island State University's Calape Campus. For the functionality of trainer board, researcher created a self-made observation guide that was validated by experts in the field of electrical, which includes registered electrical practitioners, instructors, and professors of Bohol Island State University Main Campus, Calape Campus, and Balilihan Campus. Moreover, standard deviation (SD) describes the variability of the pre-skill test and post skill-test of the students using the Electrical Fixture Trainer Board. On the other hand, independent samples t-test applying bootstrapping with 95% Bias corrected accelerated was used to test if there is significant difference on the difference between the pre-skill test and post-skill tests scores of the students who have used the Electrical Fixture Trainer Board. Bootstrapping is robust estimation method for reducing bias associated with normality, homogeneity of variance, and sampling. Probability values (p) are compared at 0.05 level of significance. IBM SPSS Statistics Trial Version was used in all the analysis. Results shows that the pre-skill test scores (M = 1.825, SD = .157) is significantly lower than the post-skill test scores (M = 1.825, SD = .157) of students, t(38) = –16.935, p = .000. This implies that the Electrical Fixture Trainer Board is an effective tool to train the students in the field of building wiring at the same time learn additional knowledge in electrical instrumentation.
