Development of React-Based LKPD (Relating, Experience, Applying, Cooperating and Transferring) On Comparisonal Materials in MTs

The formulation of the problem from this research is Is the REACT-based Development of Student Worksheets (LKPD) on Comparative Materials in MTs feasible? How is the development of REACT-based LKPD on comparative materials in MTs? as the purpose of this study is to find out whether the development of REACT-based Student Worksheets on Comparative materials in MTs is feasible to use. To be able to find out how to develop REACT-based LKPD on comparative materials in MTs. This research is a research and development Research and Development (R&D) that uses a 4D development model which consists of 4 stages, namely the definition stage, the design stage, the develop stage, and the dissemination stage. However, in this study, the researchers only limited it to the 3D stage, namely define, design and develop. The instrument in this study was a questionnaire sheet for the expert feasibility test. Based on the validation results from the validator, the RPP, LKPD assessment scores were obtained by two expert lecturers and one mathematics teacher with an average score of 3.3 and 3.4 on a scale of 4. categorized "Very feasible". it can be concluded that the REACT-based worksheets on comparative materials developed by researchers are very suitable to be used as additional teaching materials for students.
