Abstract

The study investigated the effects of Computer- Assisted Instruction on students’ achievement and retention in Radio Television and Electronic Works in Technical Colleges in Lagos State. Two research questions and two research hypotheses guided the study. The study adopted quasi- experimental research design. The instrument used for data collection are Radio Television Electronic Works Assessment Sheet (RTVEWAS) and Retention Test on Radio Television and Electronic Works (RTRTVEW) developed for the study whose reliability obtained using Guttmann Split-Half Coefficient whose coefficient value was 0.805. And the sample of the study comprises of seventy- eight (68) students which was drawn from two Technical Colleges as follows: Government Technical College (GTC) Agidingbi (experimental group) – thirty (33) and Government Technical College (GTC) Adosoba (control group) –thirty- five (35) students.
