INVESTIGATION INTO EFFECTS OF ETHNOSCIENCE BASED INSTRUCTIONAL MODEL ON STUDENTS’ ACADEMIC ACHIEVEMENT AND BIOLOGY

ABSTRACT


This study was designed and conducted to determine the effects of ethnoscience-based instructional model (ESBIM) on students’ academic achievement and interest in Senior Secondary Biology. The study employed a non equivalent control group quasi-experimental design. The sample for this study comprised of two hundred and twenty three SSI Biology Student. The study was conducted in six government co-education secondary schools in Nsukka Education Zone of Enugu State. The schools were drawn through a stratified random sampling. In each school, one intact class was drawn for the study through a simple random sampling making a total of six intact classes. Out of the six schools, three schools were assigned to the experimental group while the remaining three schools were assigned to the control group. The experimental group was taught Biology using the ethnoscience based instructional model while the control group was taught Biology using the lecture method. Two instruments Biology Achievement Test (BAT) and Biology interest scale (BIS) were constructed and validated and reliability of internal consistency and stability were established (0.96 and 0.835 respectively) before using them for data collection. The BIS and BAT were used to collect data for students’ Achievement and interest respectively. The research questions were answered using mean and standard deviation while the hypotheses were tested at (P<0.05) using analysis of covariance (ANCOVA). The result revealed that the ethnoscience based instructional model is superior to the lecture method in fostering interest and achievement among the students. The study also revealed that the use of ethnoscience based instructional model does not show any significant difference in the achievement and interest of male and female students. Thus the use of ESBIM will not only help arrest the problem of male being regarded as high achiever, in science-related courses but will also encourage the female students to enroll in such courses. Based on these, some recommendations were made which include; that seminars and workshops should be organized by government and relevant professional bodies like STAN to educate and sensitize the teachers on the proper use of the model (ESBIM). An urgent curriculum review to reflect the Nigerian culture and environment in secondary school curriculum was also recommended.
