Abstract
The role of computers in classroom instruction is gaining prominence in developing countries especially in
Kenya for Science subjects, in particular Chemistry subject whose performance has been low. This paper
presents a section of a study in Kenya which investigated the effect of Computer Aided Instruction (CAI) on
students’ achievement in Chemistry as compared with Conventional Instructional Methods (CIM). This study
was prompted by the emergence of IT resources mainly in courtesy of the government and some nongovernmental organization (NGO). The study targeted 15 secondary schools with computer laboratory in
Tharaka Nithi County, Kenya. A total comprising of 174 Form Two Chemistry students from Four secondary
schools with computer laboratory were purposively sampled. The four schools were randomly assigned to either
Experimental or Control groups. The Experimental groups were taught with CAI while Control groups were
taught with CIM (Conventional Instructional Methods) on the topics “Atomic structure, Periodic Table and
Chemical families” for six weeks. Data was collected using Chemistry Achievement Test (CAT). The CAT was
administered before and after treatment (CAI) to both Experimental and Control groups. The content validity of
the CAT was checked for by a panel of secondary school Chemistry teachers who were not from the schools
under study. The researcher administered the CAT instrument (pre-test and post-test) with the assistance of
Chemistry teachers in the sampled schools. Data was analyzed using both descriptive and inferential statistics.
The differences between the group means was analyzed using t-test, Analysis of Variance (ANOVA) and
Analysis of Covariance (ANCOVA). The statistical significance was tested at α = 0.05. The study posted a
significant difference in academic achievement in Chemistry between the CAI and CIM groups, with students of
CAI group obtaining higher Chemistry scores than students of CIM group. The study further revealed a
significant gender difference in Chemistry academic achievement in fovour of girls. Based on these findings, it
was therefore recommended that Chemistry teachers should adopt use of CAI in their teaching for improvement
of students’ academic achievement in Chemistry and in particular, the girls.
