Population

The target population for the study consisted of all the senior secondary ii (ssii) chemistry students in the five local government and development areas of Epe division of Lagos State Nigeria.
Schools and subjects: - Six senior secondary schools in Epe division of Lagos State were selected for the study based on purposive sampling technique. The six schools were selected based on the following criteria.

1. The schools had well equipped chemistry laboratories.
2. The schools’ chemistry teacher is a graduate from faculty of Education
3. The subject for the study must have been taught basic and pre-requisite concepts such as types of chemical reactions, energy changes in chemical reactions and chemical equilibrium necessary for the understanding of chemical kinetics.

All the 300 chemistry students in senior secondary two classes (ssii) in the six schools were the subjects of the study. Intact classes were used.
