Instructional Model for Power Surge
Journal Title: Scholars Bulletin - Year 2017, Vol 3, Issue 2
Abstract
Abstract:This is a quasi-experimental method of research aimed to create electronics gadget voltage time delay device for protection of electrical appliances from power spike due to brownouts at affordable cost. Result showed a fluctuation of voltage, current, and power but is ideal based on the three percent voltage drop in a line. The mean temperature for the three treatments in all replicate was normal base on the maximum temperature of the magnetic contactor which is 1000C. The device was used for electronics instruction where the performance of the students was improved based on the pretest and posttest scores. The reliability of the test based on the posttest result was 0.75 interpreted as good which means that the assessment instrument is good; however, there are probably few items which could be improved. Testing the hypothesis of no significant correlation between the pretest and the post test at 0.01 and 0.05 levels of significance, researcher failed to provide sufficient evidence to accept the null hypothesis. The knowledge and skills obtained by the students on the different processes involved during the fabrication of the device can help to engage entrepreneurial activity to augment poverty alleviation. Keywords: Electronics Gadget, Voltage Time Delay, Fabrication, Poverty Alleviation, Instructional Model, Power Surge.
