Abstract

This study aims to describe students' mathematical understanding abilities, especially in circle material. This research was conducted at MTs Nurul Yaqin Pekanbaru to 10 grade VIII students. The method used in this study is a descriptive method using a qualitative approach to analyze student answers from the given instrument. The instrument used in this study was a written test of mathematical comprehension ability with two questions. Based on the results of data analysis, it can be seen that the mathematical understanding ability of class VIII students at MTs Nurul Yaqin Pekanbaru is still relatively low. Students cannot apply formulas in simple calculations, perform algorithmic calculations, and do not understand the questions given. During learning, only a few students actively asked and answered questions given by the teacher. Students who were less active in the learning process tended to listen and take notes delivered by the teacher. Students had difficulty understanding questions, were not challenged to solve non-routine math problems, were nervous about answering questions about poorly understood mathematic material, were doubtful about being able to learn difficult mathematic material on their own, and were unable to find new ways to do difficult math problems.

Abstract

This research and development (R&D) aim to produce learning tools in the form of syllabus, lesson plans (RPP), and student worksheets (LKPD) based on discovery learning models on geometry flat-side materials to facilitate the mathematical understanding ability of 8th-grade students of junior high school that has met the valid and practical requirements. The development model used is 4-D, consisting of four stages: Define, Design, Development, and Disseminate. The research instruments used in this research are validity instruments in the form of validation sheets and practicality instruments in the form of student response questionnaires. The syllabus, RPP, and LKPD that has been developed are validated by three validators and then tested out. According to data analysis of validation results, learning tools have met the valid requirements with an average score syllabus of 3.93, RPP of 3.86, and LKPD of 3.80. The student response questionnaire showed that the practicality of LKPD has met the practical requirements with an average score of in small group trials 3.61 and large group trials 3.53. Thus, the learning tools developed have met the valid and practical requirements to be used by 8th-grade students of junior high school.
