IMPACT OF DIGITAL GRAPHICS ON SECONDARY SCHOOL BIOLOGY STUDENTS' ACHIEVEMENT ON THE CONCEPT OF POLLUTION IN AGAIE METROPOLIS OF NIGER STAE

Abstract

This study examined the impact of digital graphics (charts showing land, water and air pollution) on secondary school Biology students' achievement in the concept of pollution in Agaie Metropolis of Niger State. Quasi experimental design was adopted for the study. A total of 120 Secondary SchoolI (SSI) Biology students of from two senior secondary schools formed the sample of the study. The schools were randomly assigned to experimental and control groups and intact classes were used in each of the schools. The instrument used for data collection was the Biology Achievement Test (BAT) which was developed by the researchers and validated by Biology lecturers in the Department of Biological Science, Federal University of Technology, Minna. The instrument was also pilot tested and reliability coefficient of 0.86 was obtained using Pearson product moment correlation coefficient formula. Two research questions were raised and answered using mean and standard deviation. Also, two null hypotheses were formulated and tested using t-test analysis. The result revealed a significant difference in the mean achievement score of students taught using digital graphics and those taught using conventional lecture method. It also revealed no significant difference in the mean achievement score of male and female students taught using digital graphics. Based on these findings, it was concluded that the use of digital graphics Is more effective in improving students' achievement in Biology than the conventional lecture method. It is therefore recommended among others that Government should provide adequate and relevant digital graphics for the meaningful teaching and learning to take place at secondary school level of our educational system.
