Effect of pro-iCo module towards students’ achievements on chemical bonding

Abstract

The deterioration of Malaysian students’ achievements in Science subject is an alarming issue. Malaysian students’ enrolment in STEM at upper secondary schools has gradually declining. Effective STEM teaching materials developed by using appropriate teaching approach for improving students’ achievements in STEM field, particularly Chemistry is urgently needed. Thus, the purpose of this study was to determine the effects of the teaching module towards students’ achievements on chemical bonding. Pro-iCo Module was designed and developed by the researcher based on STEM-5E learning cycle constructivist approach via ADDIE model. This study used a One-Group Pretest-Posttest Design. A total of 30 form four Chemistry students were selected purposively from one of the secondary schools in Johor Bahru. The instruments used in this research were (i) Pro-iCo Module Evaluation Questionnaire (Pro-iCo MEQ) (ii) Chemical Bonding Achievement Test (CBAT). Descriptive analysis and inferential analysis (Paired Sample T-test) were used in analysing the data collected. Based on the findings of the Pro-iCo MEQ, the teachers agreed that the Pro-iCo Module has fulfilled all the criteria of evaluation aspects. The findings of CBAT revealed a significant difference (with the value of 22.57) between the mean of pre-test score and the mean of post-test score. The statistical analysis of Paired Sample T-test indicated that students scored significantly higher (p < 0.05) in the post-test than in the pre-test. It can be concluded that the implementation of Pro-iCo Module has significant positive impact on students achievements in chemical bonding. Hence, Pro-iCo Module could be used as an appropriate teaching module by teachers in implementing STEM approach at schools for enhancing students’ achievement in chemistry.
