Abstract:
This study was designed to improve the students’ performance in hybridization and
molecular shapes using computerized animations and models (CAM). The target
population consisted of the chemistry students of Anlo SHS, however the accessible
population comprised of the second-year chemistry students. Purposive sampling
technique was used to select one intact class for the study. The main research
instrument was test, and supplemented with questionnaire. Students’ performance in
hybridization and molecular shapes was determined by scores obtained by the
students in the Hybridization Performance Tests (HPTs) conducted before and after
the intervention. Data relating to difficulties students faced during lessons on
hybridization and molecular shapes, as well as students’ views on the integration of
computerized animation and models were collected using questionnaires. Microsoft
Office Excel was used to analyze the data. Descriptive statistics such as mean,
percentages, and standard deviations were used to discuss the research findings.
Inferential statistics of unpaired samples and paired samples t-tests were used to test
the two null hypotheses. The results of the study showed that, the students faced
difficulties in hybridization and molecular shapes. In addition, the pre-intervention
and post-intervention mean scores were 13.33 and 21.93 respectively, which indicated
a significant improvement in students’ performance after the intervention. Analysis of
the post-intervention test scores revealed mean scores of 23.80 and 20.33 for male
students and female students respectively, which indicated a significant difference in
mean performance between male and female students. The study recommended that,
chemistry teachers of Anlo SHS should integrate CAM in teaching and learning of
hybridization and molecular shapes, and training chemistry teachers and students of
Anlo SHS on the effective utilization of computerized instructional packages. In
addition, educational stakeholders must provide digital resources to enhance effective
teaching and learning of chemistry at Anlo SHS.
