EFFECT OF COMPUTER AIDED INSTRUCTION (CAI) ON STUDENTS’ ACADEMIC ACHIEVEMENT IN ELECTRONIC LIBRARIES IN NIGERIAN TERTIARY INSTITUTION

Abstract

This study investigated the effects of computer aided instruction (CAI) on students’ academic achievement in selected federal tertiary institutions in Anambra State in electronic libraries course. Two (2) federal tertiary institutions in Anambra State, Nigeria were selected for the study through purposive random sampling technique. One institution was assigned to the experimental group while the other was assigned to the control group through a simple toss of the coin. The study employed pre-test, posttest non-equivalent groups quasi-experimental design involving two groups: experimental group (30) and control (30) was used to investigate the effect of CAI method of teaching on 3rd year library and information science students’ academic achievement in electronic libraries. The instruments were validated by experts. A sample of 60 third year Library and Information Science students participated in the study. A researcher-developed instrument, Electronic Libraries Achievement Test (ELAT) was used for the collection of data. The instrument contained fifty (50) questions with a reliability coefficient of 0.91 using Pearson Product Moment Correlation. Two hypotheses were postulated and tested at 0.05 level of significance using analysis of covariate (ANCOVA). The experimental group and control groups were taught with CAI and Modified lecture methods, respectively. Data collected were analysed using mean and standard deviation. Results showed no significant difference in the posttest achievement mean scores of students taught electronic libraries using computer aided instruction method and those taught with modified lecture method. The study further revealed that female students in the experimental group had a higher mean gain than their male counterparts in the Electronic Libraries Achievement Test implying that computer aided instruction method of teaching enhance female students’ academic achievement in Electronic Libraries more than the male students. The study recommends that lecturers should adopt the use of computer aided instruction in teaching of electronic libraries in tertiary institutions in order to enhance student’s academic achievement in electronic libraries.
