Comparative Effect of Graphic Organiser and Expository teaching strategies on the achievement of Senior Secondary School students in Economics

This paper focused on the comparative effects of graphic organiser and expository teaching strategies on the achievement of senior secondary school students in Economics. Graphic organiser is a teaching strategy used to visualise the structure of knowledge, instead of describing all concepts and their relations in text as in expository teaching. The study adopted the quasi-experimental design as subjects were not randomly assigned into groups. A sample of 384 students were used for the study. The instrument was a multiple type objective questions tagged Economics Multiple Choice Test (EMCT). The findings reveal that the graphic organiser strategy is better than the expository method in enhancing students' achievement in Economics. It was recommended that workshops and seminars should be organised for teachers of Economics on the use of graphic organiser in order to improve the achievement level of students in public examinations
