THE IMPACT OF PRACTICAL LEARNING ON STUDENTS ACHIEVEMENT IN CHEMISTRY. THE CASE OF ADELE SECONDARY SCHOOL

Abstract

The purpose of this study was to investigate the impact of practical work in enhancing students’ achievements in chemistry in Adele secondary school particularly in grade 10, Sodo Woreda East Gurage zone, Centeral Ethiopia. To achieve this objective i.e. to examine impact of practical learning on students’ performance in chemistry, and on the students attitude toward chemistry; this study was employed quasi-experimental design. among a total of six targets secondary school in Sodo Woreda Adele secondary school was selected purposively. 80 students as a sample size out of 600 total populations were selected by using random sampling method. To keep the proportional allocation of students from each section, stratified sampling technique was used. The sampled students were placed in to two groups; experimental group and control group. Both the groups were exposed to the pre-test. The experimental groups were taught using the practical approach for eight week while the control groups were taught using the conventional method. The study used three instruments namely chemistry achievement tests, students’ attitude questionnaires and observation checklists were used as a data collection tools. at the beginning of the first week, both groups give the pre-test chemistry achievements and the post-test achievements test at the end of the eight week. The data obtained were analyzed using SPSS version 20. T-test was used to test the statistical significance in the hypothesis generated in the study. The significance of the results was tested at α = .05 significance level. The findings of the students showed that practical approach resulted in higher students’ achievements in chemistry and lead to improved students’ attitude towards chemistry. The study concluded that, practical instructional approach towards chemistry is an effective teaching method which chemistry teachers should be encouraged to use to enhance students’ achievements in the subject. The study recommended adoption of the practical teaching approach in order to enhance students’ achievements and improve students’ attitude towards the subject.
