Comparing Video-Textual and Audio PowerPoint Computer-Assisted Instruction on Students’ Performance in Computer Studies

The Study was on the relative efficacy of Video-textual (VT) and Audio-power point (ATPP) Computer-Assisted Instruction (CAI) on students’ academic performance in Computer Science Education. The population of the study comprised 487 NCE II Computer Studies I students (182- males and 305 females), 2022/23 academic session from the eight Colleges of Education in the South-South zone, Nigeria. Intact classes from 3 colleges with sample size of 77(26 males and 51 females), were selected from the targeted population by purposive with consideration to availability of internet and other required facilities. Simple Random Sampling (SRS) was used to place them into experimental and control groups by balloting (assigning number). A validated instrument tagged Computer Studies Education Performance Test (CSEPT) with reliability coefficient of 0.80 estimated using Kuder Richardson Formula 20 was used which was 40 multiple choice questions guided with table of specification covering Computer Studies I course topics of approved NCCE minimum standard,2020. The experimental groups were taught Computer topics using VT-CAI for experimental group1, ATPP-CAI for experimental group2, while the control group were taught using the lecture method (LM). The study was guided by two hypotheses and two research questions. The hypotheses were tested using the analysis of covariance (ANCOVA) at 0.05 level of significance (ATPP-CAI mean gain=21.07, F(2,73) = 15.780, p=000). ATPP-CAI students performed better than those of VT- CAI and LM. Those of VT-CAI alsooutperform LM students. Based on the result, it was recommended that ATPP-CAI should be integrated into the teacher training programme as a teaching method to improve students’ performance in Computer Studies I. Also, the National Commission for the Colleges of Education (NCCE) should adopt and promote ATPP-CAI as a teaching method.
