EFFECT OF COMPUTER ASSISTED INSTRUCTION ON THE RETENTION ABILITY OF TECHNICAL COLLEGE STUDENTS IN ELECTRICAL INSTALLATION AND MAINTENANCE WORK IN ENUGU STATE

Abstract

This study investigated effect of Computer Assisted Instruction on the retention
ability of technical college students in Electrical Installation and Maintenance
Work in Enugu State. A research question and a null hypothesis guided the study.
Quasi experimental research design was adopted for the study. The sample used
for the study consisted of 22 NTC II students made up of 14 males and 8 females.
Purposive sampling technique was used to select two schools from Udi and Enugu
education zones. An intact class was used in each of the schools which were tagged
experimental and control group respectively. The instrument used for data
collection was a 50 objective questions developed by the researcher which was
administered as pre-test, post-test and delayed post-test to the experimental and
control groups respectively. Pearson correlation coefficient formula was used to
establish the reliability of the instrument which yielded 0.81 coefficient reliability.
The research question was answered using mean scores whereas the hypothesis
was analyzed using ANCOVA. The mean scores and ANCOVA were calculated
using SPSS version 20. The findings showed that CAI significantly increased the
students’ retention ability. In view of the finding, it was recommended among
others that CAI should be formally adopted in technical colleges, secondary and
vocational schools for instruction in Electrical Installation and Maintenance Work
to improve retention ability of students.
