Abstract

The 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.

Abstract

This study aims to obtain a description of the surface area and volume problem solving profiles of class IX B students at SMP Negeri 1 Lore Tengah. This study uses a qualitative method with a qualitative descriptive approach. The research subjects were 3 students, namely students who had high, medium and low mathematical abilities based on the problem solving steps proposed by Polya. The research results obtained show that: (1) Students who have high mathematical abilities use all stages of Polya in solving problems of surface area and volume of cylinders. (2) Students who have moderate mathematical abilities have not been able to use all of Polya's stages in solving the problem of surface area and volume of cylinders, the stage in question is found in the re-examining stage. However, the subject gave his opinion by explaining using his own language why not re- examine the results of solving the problem given. (3) Students who have low mathematical abilities have not been able to go through all the stages of Polya in solving problems, the subject is only able to go through the stages of understanding the problem but the subject needs to read repeatedly and pay attention to the information contained in the problem repeatedly.

Abstract

This study aims to obtain an overview of fractional problem solving in terms of mathematical ability in class VII students of SMP Negeri 3 Pamona Timur. This research is a descriptive qualitative research. The research subjects consisted of three students with high, medium and low abilities. Data collection techniques in this study were written tests and interviews. The results of this study indicate that the subject's ability to solve fraction problems according to Polya's stages are as follows: (1) the stages of understanding the problem of high, medium, and low ability subjects read repetitive problems, mention information that is known based on declarative sentences and information asked based on imperative sentences or question of the problem appropriately. (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 answers
