Abstract
This study investigated students’ performance in electricity practical through the usage of micro electricity kits and conventional laboratory apparatus in Kakamega North sub-county as an intervention mechanism. Specifically the study compared the learners’ performance in an electricity practical test by students who used the micro electricity kit and those taught using conventional experimental apparatus. The research design adopted for the study was a two group quasi-experimental randomized pretest-posttest experimental design. A sample size of 537 form two students from fourteen schools were selected by stratified random sampling technique. The experimental group was exposed to the use of micro electricity kits while the control group was conventionally subjected to the same instructional technique. Two performance tests (EPT1 and EPT2) which acted as pre-test (bulbs in series and parallel) and post-test (ohms law) respectively of reliability index 0.74 and 0.87 were administered to both groups at an interval of one month between them. Validity of the instruments was determined with the help of three experienced secondary school teachers at values between 6 and 9 out of 10 for each of them. The obtained data were analyzed according to the hypothesis using both descriptive (means, percentages frequencies tables) and inferential (t-test chi square and anova) statistics. The findings indicated that students who used micro kits performed better than those who used conventional apparatus in electricity practical. Students from county schools performed better than those from sub-county schools. Male students who used the kits performed better than female students. Therefore the kits should be incorporated in the Kenyan school curriculum. These kits can be mainstreamed in physics practical work so as to provide practical experience and conceptual understanding of physics concepts. The government should provide adequate finances, laboratories, apparatus and teachers to sub-county schools so as to compete with the county schools. Physics teachers should also give attention and encourage female physics students during practical sessions such that both male and female students can perform better in the study of physics.
