EFFECTIVENESS OF MULTIMEDIA INSTRUCTIONAL PACKAGE ON SECONDARY SCHOOL STUDENTS’ ACADEMIC PERFORMANCE IN CHEMISTY

Abstract

The study investigated the effect of multimedia instructional package on secondary school students’ academic performance in Chemistry. Three research questions guided the study and three null hypotheses were tested at .05 level of significance. The design adopted for this study was quasi-experimental design. Specifically the design is a pretest-post test nonequivalent control group design. The population of the study consisted of 2,109 SS1 students made up of 1,027 males and 1,082 females in 2020/2021 academic session in public secondary schools in Enugu Education Zone of Enugu State. The sample for this study comprised 415SS1 students drawn using multistage sampling procedure. The instruments for data collection were titled ‘‘Chemistry Performance Test (CPT) which was duly validated by three experts from Faculty of Education, Nnamdi Azikiwe University, Awka. The reliability of CPT was determined using Kuder-Richardson formular 20 (k-R20) which yielded 0.84. Mean and standard deviation were used to answer the research
questions and Analysis of Covariance (ANCOVA) to test the hypothe2ses. The findings of the study revealed among others that students taught Chemistry using multimedia instructional package effectively performed more than those taught using conventional
teaching method. It is also revealed there was a significant difference between Chemistry students taught with multimedia instructional package and those taught with 8conventiona teaching method in favour of those taught with multimedia instructional package.. Based on the findings, recommended and conclusions were made.
