Abstract:
The study compared the effects of Computer Assisted Instruction (CAI) on the achievement of Junior High
School (J.H.S) students in Pre-Technical skills after exposing them to CAI and the traditional methods of
instruction. The theoretical framework for the study is that people learn most things better through
construction of computer games or multimedia composition rather than through traditional methods of
directly teaching content. The study involved 59 students from two schools in Kumasi Metropolis. Twenty
eight of the students formed the CAI group while 31formed the traditional group. Quasi-experimental
design was used for the study. Structured pre-test and post-test achievement test with a reliability coefficient
= 0.74 and 0.75 respectively were used to collect data. The data was analyzed using Predictive
Analysis Software (PASW) version 18. The study revealed that the CAI group performed better than the
traditional method of instruction group. However, there was no statistically significant difference between
the achievements levels of the two groups. It was recommended that CAI should be introduced in the
teaching of Pre-Technical skills throughout the country.
