O knihe

This is a quasi-experimental method of research aimed to create voltage time delay device for protection of electrical appliances from power spike due to brownouts at affordable cost. 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 post test scores. The reliability of the test based on the post test 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. It is established that the voltage time delay device is valuable for electronics instruction. It is recommended to follow the procedure as indicated in the proposed instructional guide for electronics technology that can be used for commercialization.
