Effects of Multimedia Projectors as Instructional Media on Secondary School Students’ Academic Performance in Chemistry

The study examined the effect of multi-media projectors as instructional media on secondary school students’ academic performance in chemistry. A pre-test-post-test control group quasi-experimental design was adopted in the study. 90 SSII Chemistry students were selected using simple non- randomized sampling technique. 45 students’ each was selected randomly to form the experimental and control groups. The experimental group was taught using multi-media projector while the control group was taught using conventional method. The instrument for the study was a Chemistry Achievement Test (CAT) multiple choice items. Data gathered for the study were analyzed at 0.05 level of significant using t-Test Statistical method. The finding showed that there was a significant difference between the mean achievement scores of students exposed to Multimedia and those exposed to conventional method, it means that multi-media projector heightens students’ understanding in chemistry. Similarly, there was no significant difference in the mean achievement scores of male and female students exposed to Multimedia-based instruction. This showed that multimedia projector is favourable to both male and female but conventional method does not. Therefore, among others it is recommended that the use of multimedia projector should be utilized in teaching and learning of Chemistry among secondary school students.
