Abstract

Development of Mathematical Learning Devices Using Geogebra-Based Problem-Based Learning (PBL) Models in Class VIII SMP Circle Materials Daniel Simamora NPM. 166411019 Thesis Program Study Mathematics Education FKIP Islamic University of Riau Mentor : Drs. Aburrahman, M. Pd ABSTRACT Mathematical creative thinking is an ability in an effort to produce varied answers or ideas in an effort to solve problems in mathematics. This study aims to produce learning tools on valid circle material using the Geogebra-based PBL (Problem-Based Learning) model. Learning tools developed in the form of lesson plans, and LKPD on circle material. This type of research is development research with the ADDIE model which has been modified into 4 stages (Analysis, Design, Development, and Evaluation) without the Implementation stages. The research data collection instrument is a validation sheet of learning devices in the form of syllabus, lesson plans and LKPD. The data analysis used is descriptive data analysis which describes the validity level of the product. This study resulted in a total average score of 92,97% RPP with a very valid category and a total average score of 91,37% LKPD with a very valid category. This study concluded that the development of mathematics learning devices using the Geogebra-based PBL model on circle material has been tested for validity.
