Full text linkThe study was to describe the ability of the eighth graders' mathematical connections to solve problems based on mathematical abilities. This type of research is a qualitative study. The subject of this study is the eighth grade 1 st student hammer with a high level, moderate ability and low capacity. The method of data collection with observation, tests and interviews through the technical data analysis phase that is the condensing of data, the presentation of data and the drawing of conclusions. The stability of mathematical connections is defined by the mathematical problem of the cube that contains the indicator of the ability of mathematics: 1) connections between mathematical concepts, 2) connections between mathematics and other disciplines, 3) connections connecting and applying mathematics in everyday life. Research shows that high-performing students are able to meet the indicator of mathematical connection capability, the gifted student only meets a portion of the mathematical competence and the underprivileged student is not yet able to meet the indicator of mathematical connection
ANALISIS PEMAHAMAN SISWA DALAM MENYELESAIKAN SOAL CERITA SISTEM PERSAMAAN LINEAR DUA VARIABEL DI KELAS VIII C SMP IT QURROTA A’YUN PALU: Analysis of Students Understanding in Solving Analytical Questions of System of Two Variable Linear Equations (TVLE) in Class VIII C at SMP IT Qurrota A’yun Palu
Full text linkThe purpose of this study was to describe the understanding of Class VIIIC students of SMP IT Qurrota A'yun Palu in solving the story problems of the Two Variable Linear Equation System. The research using a qualitative descriptive approach. The result of this study is that the understanding of students with high abilities shows that students tend to have a good understanding, both from understanding translation, understanding interpretation, and understanding extrapolation. The understanding of students with moderate ability shows that students have a good understanding of understanding translation and interpretation, but lacking in understanding extrapolation. Moderately capable students are able to convey and understand story problems, interpret and describe the intent of the questions, and determine the concept or appropriate steps properly and correctly. However, it is inaccurate and there are errors in applying the concept of mathematical calculations and concluding answers. The understanding of low-ability students has a fairly good understanding, on translational understanding, low-ability students can convey and understand story problems, but are unable to interpret and describe the intent of the questions, determine concepts or steps for solving problems and are unable to apply the concept of calculation and conclude the answer completely, which means that low-ability students are very lacking in understanding interpretation and extrapolation

(2) the stage of preparing a problem solving plan for subjects with high, medium, and low abilities in making a problem solving plan, namely stating the information asked to make a mathematical model in the form of adding and subtracting fractions based on what is known correctly. (3) the stage of carrying out the problem-solving plan, high-ability subjects carry out the problem-solving plan in accordance with what has been planned correctly, while subjects with moderate and low ability carry out the problem-solving plan according to what was planned beforehand but not quite right. (4) the stage of re-examining the results of solving high-skilled subjects did not write down how to check answers, but when interviewed by researchers, high-skilled subjects were able to re-check the answers that had been written down. Meanwhile, subjects with medium and low abilities were sure of their answers and did not re-check their answers, because they did not understand how to re-check their answer
