Learning Media Based on Three Level Representation and Inquiry for Electrolysis Cell Materials

Abstract

Research has been conducted aimed at designing three-level representation-based learning media in electrolytic cell material. The research product in the form of a model kit equipped with inquiry-based worksheets was developed through the stages of design based research. The model kits and worksheets produced have the characteristics: integrating macroscopic, submicroscopic and symbolic levels of representation, developing the ability of chemical representation and scientific performance. The submicroscopic and symbolic representations are explored using particle models made of magnetism to simulate the transfer of ions and electrons during an electrolysis reaction. Validation and testing of products and inquiry-based worksheets show the product is valid and feasible to use.
