Validity and practicality of worksheet assisted by PhET interactive simulations to improve students creative thinking skills in a research based learning model

Abstract

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. The result showed that the validation of the students worksheet obtained an average score of 0,83 on the aspects of the feasibility of content, presentation, and language. The practical result obtained for the teachers response were 75% with the practical category and 81,70% for students responses with the very practical category. Based on the results of the developed phet assisted worksheets, it is stated that they are valid and practicality used in research based learning to improve the creative thinking skills of students at the high school.
