Effects of Computer Assisted Instructional Software on Senior Secondary School Students? Learning Outcomes in Volumetric Analysis in Ekiti State, Nigeria

This study investigated the effects of computer assisted instructional software on senior secondary school students? learning outcomes in volumetric analysis in Ekiti State, Nigeria. The purpose of the study was to investigate the effects of computer assisted instructional software and the influence of students? attitude on senior secondary school students? learning outcomes in volumetric analysis. The study adopted pre-test and post-test control group quasi- experimental research design of the survey type. The sample of this study was 108 senior secondary school II students in Ekiti State which was drawn out using multistage random sampling technique from a total population of 15,276 senior secondary school II students in Ekiti State, Nigeria. Three research instruments were; Students? Attitudinal Scale towards Volumetric Analysis (SASVA), Students? Volumetric Analysis Practical Test (SVAPT) and Computer Assisted instructional Software (CAIS)which were used to collect relevant data from the respondents. Face and content validity of the instruments were ascertained by experts in Computer Science with high experience in software programming, Science Education and Test, Measurement and Evaluation. Corrections made were properly incorporated into the instruments to make the final and corrected version. Test-retest method was used to establish the reliability of SVAPT as administered to 20 students outside the normal sample with interval of two weeks and co-efficient correlation value of 0.85.Cronbach?s Alpha was used to determine the internal consistency of the items in SASVA and CAIS and the Co-efficient values obtained were 0.73 and 0.87 for SASVA and CAIS respectively which is high enough to make the instruments reliable. Data collected were analyzed using t-test for hypothesis one and Analysis of Co-variance (ANCOVA) for hypotheses two and three at 0.05 level of significance. The result showed that students? performance in computer assisted instructional software group at post-test was found to be significantly better than that of the control group. The findings also revealed that computer assisted instructional software is highly sensitive to students? attitude. Based on the findings of the study, it was concluded that computer assisted instructional software improved students? achievement in Volumetric Analysis. It was therefore recommended that this new instructional strategy should be introduced to the teaching of Chemistry and Volumetric Analysis.
