Identifying the Mathematical Concept Understanding Ability of Junior High School Students in Learning Linear Function Material

Understanding mathematical and mathematical concepts is one of my fundamental abilities. Therefore, it is necessary to teach mathematics by emphasizing concept understanding so that students are trained to solve problems with the concepts they understand appropriately. This study aims to analyze the knowledge of mathematical concepts of students at junior high school level grade VIII on linear function material. This research is qualitative research with a descriptive method. The research subjects were VIII grade students, as many as 33 students. Data collection through two description questions was then analyzed according to the ability of high, medium, and low student categories. Furthermore, direct interviews were conducted to obtain more in-depth information about students' understanding of mathematical concepts. The results showed that 39.39% of students had high-category mathematical concept understanding ability (ST), 6.06% of students in the medium category (SS), and 54.55% of students in the low category (SR). ST fulfills all indicators with the correct answer, and SS fulfills all indicators, but the answers produced could be more precise. SR cannot apply concepts, so it only fulfills some indicators, which results in errors in solving problems.

Pengaruh Model Pembelajaran Kooperatif Tipe Scramble Terhadap Pemahaman Konsep Matematis Siswa SMP

This research is motivated by the importance of the ability to understand mathematical concepts. This is because mathematical concepts are related to one another so that learning them must be continuous and continuous. But in reality there are still many students who cannot understand the learning concept as a whole. One of the efforts and solutions to overcome this is that there must be an update in the learning model, the Learning Model which is expected to improve students' understanding of mathematical concepts is the scramble type cooperative learning model. The purpose of this study was to determine whether there is an effect of scramble type cooperative learning model on students' understanding of mathematical concepts. This type of research is a experimental research. The population in this study were all seventh grade students at one of the junior high schools in Kerinci. The sample consisted of two classes selected by probability sampling. The instrument used was a test of mathematical concept understanding ability. Data analysis using Independent t-test. Based on data analysis, it was found that there was an effect of scramble type cooperative learning model on students' mathematical concept understanding ability with the average value of the experimental class of 88.03 and the control class of 78.10.

Analysis of Students' Mathematical Concept Understanding Ability on Circle Material Based on Learning Style

This research aims to analyze students' mathematical concept understanding ability in solving circle material problems by considering learning styles. The method used in this research is qualitative method with descriptive approach. This research was conducted on students of class XI Culinary 1 at SMKN 6 Semarang which amounted to 36 students. Data were collected through mathematical concept understanding test and student learning style questionnaire. The subjects in this study were three students who represented each student's learning style. The techniques used to collect data were observation, mathematical concept understanding ability test, interview and documentation. The results showed variations in learning styles and variations in students' mathematical concept understanding abilities in solving circle material problems. Learners with visual and auditory learning styles tend to have better understanding abilities in solving the problem, while learners with kinesthetic styles show different patterns. So it can be concluded that the learning style of learners can affect students' mathematical understanding ability in solving circle material problems, therefore the importance of recognizing the learning style of students in the mathematics learning process.
