Comparison of the Effects of Improvised Electrical Models On Students Academic Achievement In Male And Female Technical Colleges In Borno State, Nigeria

Abstract

The study was conducted to find out the comparative effects of teacher-improvised electrical models on academic achievement of students in basic electricity at the technical college level in Borno state, Nigeria. Four research questions and four null hypotheses were considered and tested. The pretest posttest experimental research design was employed for the study. The population for the study consisted of 90 students from the only two technical colleges that offer basic electricity. All the population was considered for the study as there was no sampling. The students were randomly assigned to either experimental or control groups. Structured questionnaire titled; Researcher made achievement test (RMAT) and Researcher made retention test (RMRT) were used for data collection. RMAT and RMRT consist of 50 items each with four options. The draft of the RMAT and RMRT and table of specification were given to six experts of varied years of teaching basic electricity from Modibbo Adama University of technology, Yola and Ramat Polytechnic, Maiduguri, for comments and suggestions. Mean standard deviation and t – test statistics were employed for data analysis at 0.05 level of significance. The findings include; there was a significant difference between the mean ratings of students taught BE using improvised electrical models and students that were taught BE using conventional method in posttest, also; there was no significant difference between the mean ratings of male and female students taught BE, using improvised electrical models in a retention test. It was recommended that, workshop should be organized at technical colleges; to introduce the need for teacher improvised electrical models and stress the importance of electrical models to practicing teachers.
