Abstract

This study examined the effect of Video-CD and Audiocassette-based instructions on secondary school students’ environmental practices on Disease control in selected environmental topics in Biology. The study adopted a pretest, post-test, control group, quasi experimental design using a sample of 352 S.S.1 Biology students from six secondary schools, randomly selected from 4 Local government areas of Ibadan in Oyo State. Five instruments were used and three hypotheses were tested. The data analysis revealed a significant difference between (a) students exposed to Video-CD and control group (b) students exposed to Audiocassette and control group (c) Gender and parents’ level of education in their environmental practices.  However, there was no significant main effect of gender on students’ environmental practices. Appropriate recommendations were advanced for the use of ICT-based instructions.
