Abstract


Researchers and scholars in the field of education have suggested a shifting focus from conventional strategies to student centered strategies such as Group Investigative Laboratory strategies. Studies have shown that these teaching strategies are influential in determining studentsí achievement in Biology. The present research involved the effect of Group Investigative Laboratory strategies, on studentsí achievement in Biology. The study adopted a pretest, posttest, control group, quasi-experimental research design. 157 senior secondary school students participated, with nine intact classes from nine schools from three local government Area of Oyo state. Two research Hypothesis was tested at 0.05 Alpha level, Five instruments used in the study were: Four instruments used for this study and they were; Biology Achievement Test (BAT), Teachersí Instructional Guide on Group Investigative Laboratory Learning Strategy (TIGGILLS), teachersí Instructional Guide on Conventional Lecture Method (TIGCLM), evaluation Sheet to Assess Teachersí Performance (ESAT). Data were analyzed using ANCOVA. There was a significant main effect of Treatment groups on the studentsí post test Achievement scores (F(2,139) =32.559, P <.05, η2 = .321). Group investigative strategy was significantly different from the conventional strategy in their achievement scores. The exposure of the learners to Group Investigative Laboratory strategies have been found to positively affects the enhancement of studentsí achievement in Biology

Keywords: Group investigative strategy, Achievement, Gender and Biology.
