Implementation of Conceptual Change Approach to Improve Learners’ Understanding of Quantitative Chemistry Aspects

Abstract

Implementing a conceptual change approach helps students correct misconceptions and gain a deeper understanding of key quantitative Chemistry concepts, including stoichiometry, chemical equations and substance quantity calculations. For improvement of how learners understood quantitative aspects as measured with chemical change, a conceptual change approach became the centre of inquiry. A case study and qualitative approach were used to collect data from 50 learners and 12 learners. The findings indicate an improvement in learners’ scientific understanding after the administration of a pre-test and a post-test. Concurrently, provided by this study is evidence denting that misconceptions of learners can be facilitated with great conceptual understanding through the application of a conceptual change framework. The study recommends a well-designed conceptual change instructional approach that leads to significantly better acquisition of scientific concepts.
