Abstract

This research is motivated by one of the objectives of learning mathematics is so that students have the ability to understand mathematical concepts. However, the reality on the ground shows that students' ability to understand concepts is still low, so it requires a teacher's understanding of the factors that influence it, namely learning styles. This study aims to describe the ability to understand mathematical concepts in terms of learning styles. The approach used is descriptive qualitative. The research subjects were 3 students from 21 grade VII-A students of SMPN 3 Cikampek. Data was collected through learning style questionnaires, written tests, and interviews. This study's results indicate that students with different learning styles have different results in understanding concepts. Visual learning style students in general are quite capable of meeting indicator of ability to understand mathematical concepts that can meet 3 indicators, students of auditory learning style are generally said to be good or almost meet every indicator of ability to understand concepts that can meet 5 indicators, while kinesthetic learning style in general not good at fulfilling each indicator, which is only able to meet 2 indicators of the ability to understand mathematical concepts.

Abstract

Analysis of students' difficulties aims to assist teachers in analyzing difficulties in solving material relationships and functions. The research method used is phenomenologically qualitative in junior high school in one of the schools in Karawang district in the odd semester of the 2022/2023 academic year. Sampling was 41 students of class VIIIB. In this study, this collection technique took data with test results based on the number of questions as many as 3 questions and what was used was tests and interviews, based on the results of analysis and discussion and observation. The validity of the data used in this study is a type of source triangulation. The results of this study indicate that students who experience difficulties in solving material relations and function questions are: (1) junior high school students who have difficulty using concepts because students cannot translate the form of the questions, so they cannot use the appropriate formula. (2) ) junior high school students have difficulty using principles because students cannot process calculations, so students do not complete calculations correctly, (3) junior high school students have difficulty solving verbal problems because students cannot use concepts and principles to work on problems on questions.
