Development of Guided Invention Based Learning Tools on Circle Material to Facilitate Mathematical Comprehension Ability of Class VI SD / MI

This research was motivated by the lack of teachers in developing learning tools causing students' mathematical understanding is still low category. The devices used schools have not trained skills. aim this study to produce guided discovery-based mathematics facilitate comprehension skills that meet validity and practicality requirements. type a development using ADDIE model. instruments were syllabus validation instrument, lesson plans, student worksheet response questionnaires. Based on results data analysis, it shows device valid syllabus, RPP LKPD showed category very with value sequentially obtaining score 92.5%; 95%; 94.87%. analysis small group trials practical 93.64%. It can be concluded developed are feasible use process.
