Abstract

This study aims to obtain a description of the problem solving profile of SPLTV students of class X SMA Negeri 1 Banawa Tengah in terms of mathematical ability. 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 results obtained indicate that: (1) Students who have high mathematical abilities use all stages of Polya in solving SPLTV problems. (2) Students who have moderate mathematical ability have not been able to use all of Polya's stages in solving SPLTV problems, the stages in question are in the re-examination stage. However, the subject gives his opinion by explaining using his own language why not re-examine the results of the completion of the given problem. (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 stage of understanding the problem but the subject needs to read and pay attention to the information on the problem repeatedly.

Abstract

This study aims to describe the problem solving of fractional. This type of research is descriptive using a qualitative approach. The subjects of this study were grade VII students of SMP Negeri Model Terpadu Madani Palu consisting of 3 students who were divided into 1 student with high mathematical abilities, 1 student with moderate mathematics ability, and 1 student with low mathematical abilities selected based on processing the final semester exam scores in odd semester 2021/2022. The results showed that students whit high math skills were able to solve problems well based on Polya’s problem solving steps, starting from the stage of understanding the problem, to the stage of re-examining the answers. Students who are mathematically capable are doing mathematical problem solving well at the stage of understanding the problem, the stage of making plans, but at the stage of implementing the plan students are wrong in changing the fraction division operation into the form of fraction multiplication operations, moderately capable subjects do not change the position of the numerator into the denominator and the denominator into the numerator which is the settlement area, the stage of re-checking the students answers only checks again by looking at the results of the answers. Students whit low math abilities have not done problem solving well, that is, they can only rewrite existing information without understanding the existing information, unable to make plans because they feel confused in thinking about plans that must be used to solve problems, cannot carry out problem solving plans. And can’t recheck the answer. This is because students cannot solve the given problem.

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

Abstract

This study aims to describe the creative thinking ability of students with high and moderate abilities in solving open ended quadratic equation problems in class XI MTsN 1 Palu City. The two students selected as research subjects consisted of a high-ability student and a medium-ability student. This type of research is qualitative research. The data collection techniques used are tests and interviews. The results showed that the subjects had high and medium abilities, (1) At the fluency stage, high and medium ability subjects met all indicators where students were able to solve the given problems with various ideas or solutions to do the problems, (2) At the flexibility stage, high-ability subjects had met all indicators where students could do in two ways, namely the first to do by factorization and the second to do by using the ABC formula, while moderate ability has not met the fluency indicator because it has not been able to do it in another way, (3) At the novelty stage, high-ability and medium subjects have not met the novelty indicator where students have not been able to create or do it in their own way. High-ability subjects meet 2 indicators so that the level of creative thinking of high-ability subjects is at level 3, namely the creative category. While the subject with moderate ability meets 1 indicator so that the level of creative thinking is at level 1, which is the less creative category.
