EFFECT OF COMPUTER GRAPHICS INSTRUCTIONAL MODE ON MALE AND FEMALE SECONDARY SCHOOL STUDENTS’ INTEREST AND ACHIEVEMENT IN GENETICS IN ANAMBRA STATE OF NIGERIA
Keywords:Computer graphics instructional mode, interest, genetics
There is a perceived trend of poor academic achievement and retention of students in genetics in Nigerian secondary schools today. This situation has been attributed to many factors one of which is poor method of teaching. It is against this background that this study determined the effects of computer graphics instructional mode on secondary school male and female students’ interest and achievement in genetics. Four hypotheses were tested at 0.05 level of significance. The research design was quasi – experimental. Two groups (one experimental and one control) made up of 135 senior secondary one (SS1) students were drawn from a population of 2,608 SSI students. Purposive and simple random sampling were used to select three public secondary schools from Aguata Education Zone of Anambra State. Two instruments were used for data collection namely- Genetics Interest Scale (GIS) and Genetics Achievement Test (GAT). Three experts validated the instruments. The instruments were trial tested and the GIS gave a reliability coefficient of 0.85 while the GAT gave a reliability coefficient of 0.89. Before treatment was given, the students were pretested with the GIS and GAT. After five weeks of teaching they were post-tested with GIS and GAT though the items were reshuffled to make the instrument look different from the pretest. Analysis of Co-variance (ANCOVA) was used to test the null hypotheses. The findings indicated that computer graphics instructional mode had significant effect on the mean interest and achievement scores of students in genetics. Based on the findings, it was recommended among others that biology teachers should adopt computer graphics in the teaching of genetics in order to enhance the interest and performance of students in genetics. Government and education authorities should sponsor biology teachers to workshops and seminars to learn how to improve their teaching skills using computer graphics.
