Effects of Real Objects and Posters on Academic Performance in Biology among Secondary School Students in Katsina State, Nigeria

Abstract

This study examines the Effects of Real objects and Posters on Biology Students’ Academic Performance in Secondary Schools of Katsina State. Two research objectives formulated were answered by two research questions, and two null hypotheses tested at a 0.05 level of significance. The research design for the study was quasi-experimental consist of three groups; Real objects, Posters and control groups that were randomly selected from 24 secondary schools in Katsina and adapted pretest, posttest non-Equivalent experimental control group design. The adapted biology performance test (BPT) was validated by the researcher’s supervisor and other professionals in the Department of Biology and Science education. Cronbach alpha reliability coefficient of 0.71 was Obtained as the reliability coefficient of the research instrument. The data collected were analyzed by using descriptive statistics (Mean and standard deviation) and inferential statistics (Independent t-test was used for testing the null hypotheses formulated. The findings from this study revealed there is Significant difference between the experimental and control groups in terms of academic performance of the students exposed to Real object and Posters where the Real object and Picture groups significantly performed better than the control groups. The study concluded, the students who were taught using Real object and Posters elevates student learning and performance of the students in the Control group. It was recommended among others that; teachers should be supervised to ensure frequent use of Real object and Posters in their day-to-day teaching exercise
