Development of Mathematical Learning Devices Based on Contextual Teaching and Learning (CTL) on Cube and Block Materials in Class VIII SMP Masmur Pekanbaru WIDYANTI NPM. 176410544 Thesis. Mathematics Education Study Program FKIP Islamic University Riau Supervisor : Dr. Hj. Zetriuslita, S.Pd., M.Si ABSTRACT The purpose of this research is to produce mathematics learning devices in the form of lesson plans (RPP) and Student Worksheets (LKPD) based on Contextual Teaching and Learning (CTL) on cube and block material for class VIII SMP that have been tested for validity. The development of learning tools in this study uses the R&D development model from Sugiyono. Due to the research being conducted during the Covid-19 pandemic, the researchers limited the development procedure to 6 stages, namely: potential and problems, data collection, product design, design validation, design revision, and final product. The data collection instruments used in this study were the RPP validation sheet and the LKPD validation sheet. The data collection technique used a non-test technique in the form of a validation sheet given to 4 validators, namely 2 lecturers of Mathematics Education FKIP UIR and 2 mathematics teachers. The data analysis technique used is descriptive quantitative data analysis. The results obtained from the validation of the lesson plan were 87,06% with a very valid category and for LKPD validation it was 88,18% with a very valid category. Based on this development research, it produces a Contextual Teaching and Learning (CTL)-based mathematics learning tool that has been tested for validity
