Abstract

The effect of lecture method supplemented with powerpoint presentation and the moderating effect of learning style on students’ achievement in biology were examined in the study. Randomized pre-test, post-test, control group, quasi-experimental design, involving 2x3 factorial matrix was adopted. The sample consisted of seventy four (74) SS 2 students offering biology in two purposively selected secondary school from Sagamu local government areas of Ogun State. Three hypotheses were formulated and tested at 0.05 level of significance. Three instruments were used to gather required data: Biology Achievement Test (r=0.69), Learning Style Self-Assessment Test (r=0.82) and Lecture Method supplemented with Powerpoint Presentation guide. Data were analyzed inferentially by analysis of covariance (ANCOVA). Multiple classification analysis (MCA) was used to analyze the data. Lecture method supplemented with powerpoint presentation had significant effect on students’ achievement in biology (F(1,61)=10.652, P< 0.05). However, no significant main effect of learning style was found on students’ achievement in biology (F(1,61)= 0.594, P>0.05). No significant 2-way interaction effect of learning style was found in students’ achievement in biology (F(2,61)= 0.312, P>0.05). In view of the findings, it was recommended that teachers should be encouraged to incorporate and integrate the use of lecture method with powerpoint presentation in the teaching of biology at senior secondary schools in Nigeria.
