Effectiveness of Multimedia Instructional Strategy on Academic Performance of Senior Secondary School Students in Chemical Kinetics in Benue State

Abstract

This study investigated the effectiveness of multimedia instructional strategy on secondary school 2 students’ performance in chemical kinetics in Benue State, Nigeria. Two research questions and two hypotheses were guided the study. The study adopted quasi experimental research design of non –randomized pretest posttest control group type. The population of the study was 1,050 while a sample of 162 (88 male, 74 female) SS2 students who offer Chemistry were drawn from four secondary schools using multistage sampling technique. The research instruments were: Multimedia Instructional Package (MIP) and Chemistry Performance Test (CPT). The CPT was trial-tested on 40 students. Kuder - Richardson 20 formula was used to determine the reliability coefficient of CPT which was 0.97. The research questions were answered using mean while hypotheses were tested at 0.05 level of significance using ANCOVA. The findings of the study revealed that there was a significant difference between the mean performance scores of students taught chemical kinetics using MIS and students taught with the conventional chalk and taught strategy. There was no significant difference between the mean performance scores of male and female students taught Chemistry using MIS. The study recommends among others that since multimedia instructional strategy has been found to enhance students’ performance in chemical kinetics, Chemistry teachers should be encouraged to adopt the instructional strategy for teaching chemical kinetics in Chemistry.
