Chem-a module based on stem approach in chemical bond

Abstract

The aim of this research is to develop a Chem-A Module based on STEM approach in Chemical Bond topic. This is based on previous studies found that there have problems of Chemical Bond topic among students and conventional teaching strategies that are less beneficial to the students. Therefore, the researcher convince that it is required to find other initiatives in enhancing the understanding of students in this topic by using teaching strategies based on the STEM approach. It is allign with Malaysia's Education Development Plan (2013-2025) who wish to apply STEM as a new learning approach to increase students' interest and provide them with the challenges of this changing world. In addition to the STEM approach, this module applies lesson planning through problem-based learning and problems are given in the form of scenarios. The objective of this research was to look at the effectiveness of the module among the students on the Chemical Bond topic and to see the teacher's perspective toward this module. The entire design of this research is quantitatively in the form of pre experimentation based on one group. Sample selection was determined based on a purposive sampling method, which is 30 students were selected as the sample of the study. This study was initiated with pre-test implementation, followed by Chem-A Module exposures and ended with post-test. Furthermore, pre-test and post test were analyzed descriptively using SPSS software to obtain pre-test mean value and post-test mean value and then t-test was used to identify whether there was significant difference between pre-test and post-test among students. In addition, in looking at the teacher's perspective on this module, the questionnaire was distributed to 10 teachers and the findings were analyzed using SPSS software to obtain the frequency and percentage values for each item. Overall, the findings show that Chem-A Modules can enhance students' understanding in Chemical Bond topic. This is proven by increased marks in post-test compared to pre-test and there is a significant difference between pre-test and post-test. The findings also found that most teachers gave positive feedback on this module. In conclusion, this Chem-A Module shows good effect in terms of understanding students in the Chemical Bond topic and the teacher's perspective on this module
