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 co- efficient g = 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.

I ntroduction In this present digital era, development in various aspects of computer technology has reached a stage beyond our imagination and expectations. Even though the computer has a lot of applications in various fields, one should not forget its applications in the field of education. It is very useful and helpful in the teaching and learning process, therefore computer literacy is very much needed for teachers as well as learners. The computer has created a revolution in education and the nature of learning process. It has great effect upon our educational system as such teachers should be in terms with the physical reality of
