EFFICACY OF DEMONSTRATION AND PROBLEM-SOLVING TEACHING METHODS ON BIOLOGY STUDENTS’ ACADEMIC PERFORMANCE IN ESAN-WEST L.G.A OF EDO STATE.

E P Okhankhu

Abstract


The paper investigated the efficacy of demonstration and problem-solving teaching methods on Biology students’ academic achievement in Esan-West Local Government area of Edo State. A Quasi-Experimental pre-test, post-test control group was adopted for the study. A sample of one hundred (100) SS2 students were drawn for the study using the simple random sampling technique as well as non-proportional sampling technique. Two research questions and two corresponding hypotheses were tested in the study at 0.05 level of significance. Biology Achievement Test (BAT) constituted the source from which the students’ academic achievements were measured. The BAT was developed by the researcher and reliability coefficient of 0.57 was established using Kuder Richardson Formula 20 (KR20). Mean was used to answer the research questions and independent t-test was used to test the hypotheses. Results showed that demonstration method have a positive effect (p = 0.003 < 0.05) on students’ achievement in Biology. On the other hand, problem- solving methods had a positive but insignificant effect (p = 0.056>0.05) on students’ achievement in Biology. Based on these findings, it was recommended among others that demonstration method should be used more in Biology lessons in Esan-West Local Government Area in order to foster better retention and assimilation. Also, conclusions based on the findings were also made.
