EFFECTIVENESS OF COMPUTER AIDED INSTRUCTIONS (CAI) ON STUDENTS' PERFORMANCE IN BASIC ELECTRICITY IN TECHNICAL COLLEGES IN RIVERS STATE OF NIGERIA

The study focused attention on the effectiveness of Computer Aided Instructions (CAI) on students’ performance in basic electricity in technical colleges in Rivers State. The study adopted the pretest posttest quasi experimental design method. The population of the study comprises of all the vocational I basic electricity students in the five technical colleges in Rivers State. They comprised of 93 students. Purposive sampling technique was used to select two Government Technical Colleges and a sample size of 60 students was randomly selected for the study. This sample size comprised of 30 males and 30 females. The research instrument used for the study was the Basic Electricity Test (BET). The instrument was validated by two lecturers from technical education department of Ignatus Ajuru University of Education Port Harcourt. The reliability of the instrument was done using test-re-test method and Pearson’s product moment correlation was used to obtain a coefficient of 0.65. Two research questions were drawn and two hypotheses were formulated for the study at 0.05 level of significance. The data for the study were analyzed using Mean and Analysis of Covariance (ANCOVA). The result indicated that students taught using Computer Aided Instructions (CAI) performed significantly better than those taught using conventional method. Also, there was no significant difference in the post test performance scores of male and female students. Some recommendations were made from the findings.
