Abstract

Learning materials about solubility and solubility products tend to discuss the calculation aspects only. Therefore, it requires media able to describe the dissolution process in sub-microscopic and symbolic, namely using computer-based simulation. A learning using inquiry model supported by simulation media, PhET-SS, is required in order to make students capable of mastering the concept and to improve learning effectiveness in the classroom. This study aims to analyze the improvement of students mastery on the concepts of solubility and solubility products after learning using inquiry model supported by PhET. The method used in this study is pre-experimental method with one group pre-test and post-test design. The subject of this study consists of 38 science students at senior high school. The research instrument used is in the form of mastery test on the concepts of solubility and solubility products. The result data is tested using N-Gain. The results show that the application of inquiry model supported by PhET-SS can improve the students mastery on the concepts of solubility and solubility products. It can be seen form the number of students experiencing increased mastery of the concept in high, medium and low category with average N-Gain in the medium one.
