An Improvised Electrical Multi-Circuit Demonstration Gadget: A Technical Feasibility Study

Abstract

This study attempted to devise an electrical multi-circuit demonstration gadget for lessons in electricity. Specifically, it aimed to answer the following questions: (1) What is an improvised electrical multicircuit demonstration gadget? (2) What electrical circuit concepts can be demonstrated in this gadget? (3) What are the tools, supplies and materials needed in its construction? (4) How is this gadget constructed and operated? (5) What is the economic utility value of this gadget? This gadget is made up of an ordinary plywood 876cm x 89cm x 1.27cm for the board and a 76cm x 89cm x .39cm plywood for the back cover with the electrical component mounted on the board. The effectiveness of this gadget as a teaching device was originally tested before the members of the panel of examiners who selected at random the concepts demonstrated during the defense of this paper. The study had the following conclusions: (1) The gadget can be used to demonstrate twenty-four concepts in electric-circuit, (2) The gadget is efficient and effective in terms of teaching the students. Based on the findings and conclusions of this study, the researcher recommends the following: (a) further studies on improvisation of other teaching devices in industrial and electrical technology should be encouraged, (b) reproduction of this improvised electrical multi-circuit demonstration gadget immediately after its approval should be required of every instructor or teacher in electricity under the expense of the school with the electricity students providing the labor, and (c) the reproduction thereof should be considered as a group project of the electricity students.
