Abstract

This research is motivated by the low ability of students to solve mathematical problems, which is reflected in the results of surveys and previous research. Even though mathematics is considered an important subject, many students still experience difficulties in understanding and solving mathematical problems, including solving problems with systems of linear equations in one variable. The research method used is descriptive with a quantitative approach. This research aims to describe and analyze students' problem solving abilities. The subjects used were 30 selected class VIII students at Al-Faruqi Middle School. Data was collected through tests, then analyzed to identify student errors in solving problems on systems of linear equations in one variable. The results of the research show that the majority of students experience difficulty in understanding basic concepts, are less thorough in the problem solving process, have difficulty understanding problem questions, and have difficulty allocating time when working on questions. Based on data analysis, the percentage of student errors is classified as moderate. From these results, it is concluded that further efforts are still needed to improve students' mathematical problem solving abilities, especially in the context of one-variable linear equation systems. This can be done by focusing more on identifying factors that cause student errors and developing learning strategies that are more effective in improving students' understanding and problem solving skills in mathematics.

Abstract

Mathematical communication skills are crucial for developing students' critical thinking in mathematics learning; however, many students still struggle in this area. This study aims to analyze students' mathematical communication skills on the topic of triangles. The research employed a descriptive qualitative method with six students as the research subjects. Data were collected through essay tests and interviews. The results show that overall, students' mathematical communication skills are categorized as high, with one indicator classified as very high, namely the ability to create models of situations or problems using oral, written, concrete, graphical, and algebraic methods. Three indicators are categorized as high: reflecting real objects, images, and diagrams into mathematical ideas; reading and understanding mathematical representations; and making conjectures, constructing arguments, and generalizing. One indicator is categorized as low, namely the ability to express daily events in mathematical language or symbols. Students tend to have difficulty connecting contextual problems to mathematical symbols. These findings highlight the importance of enhancing students' mathematical communication skills in the learning process.
