Abstract

This research is a development research which aims to produce learning tools in the form of LKPD with a valid and practical Problem Based Learning model. The learning material used in this research is one-variable linear equations and inequalities in class VII SMP/MTs. This study uses the development of R & D (Research & Development) with the ADDIE model with the stages of Analysis, Design, Development, Implementation, and Evaluation. The research data collection instrument was in the form of student worksheet validation sheets which were validated by two Mathematics Education Lecturers at UIR FKIP and two Mathematics Subject Teachers at MTs Miftahul Khairiyyah Ummah, and student response questionnaires. The data collection technique used is to the validity of Student Worksheets and the practicality of Student Worksheets. The analysis technique used is the validity technique and the practicality technique. The validator results obtained from the results of the validity of the Student Worksheet are 89,93% with a very valid category. And the research results obtained from the students' practicality questionnaire results were 84,43% in the very practical category. Based on the results of this study, it can be concluded that the PBL-based LKPD on one-variable linear equations and inequalities in class VII SMP/MTs developed is feasible to use after being reviewed from the value of its validity and practicality.
