Research has been carried out to determine the validity and practicality of the sheet using interactive simulations. This study aims to describe the validity and practicality of worksheets as a learning tool in research based learning model. The method used is descriptive analysis of quantitative data, the teachers response and the students responses to the questionnaire instrumen.
