Effect of Audio-visual Materials on Students’ Achievement in Biological Concepts in College of Education, Oyo

Students’ achievement in Biological Concept is not encouraging over the years in Nigeria Colleges of Education. This may be due to Biology lecturers’ failure to make use of audio-visual materials in their classes, which could be due to lack of audio-visual materials and lack of knowledge of how to use the materials where they are available, lack of enthusiasm and inventiveness on the part of lecturers. This study was conducted on the “Effect of Audio-visual Materials on Students Achievement in Biological Concepts in College of Education in Oyo. A quasi-experimental design which involves pre-test, post-test and non-equivalent intact group was used for the study. One hundred and ninety-six (196) 200 Level NCE students’ were randomly selected from the College of Education in Oyo. Two (2) research questions were asked and answered using mean and standard deviation while ANCOVA was used to test the formulated hypotheses at 0.05 level of significance. The Biological Concept Achievement Test (BCAT) was the tool used for data collection. A reliability index of 0.80 using Kudder-Richardson formular (Kr 20). The findings revealed that students taught with audio-visual material have a higher achievement score of 2.03 and 2.15 in Biological Concept than their counterpart while p=0,000 . It was recommended that lecturers of colleges of education should practice the use of Audio-visual materials in teaching Biological concept for better achievement.
