Abstract

This study aims to describe the mathematical problem solving of class XI students of MAN 1 Palu on the material of sequences and series in terms of learning styles. The subjects in this study were three students of class XI MAN 1 Palu with visual, auditory and kinesthetic learning styles. The results of this study indicate that (1) the subject of visual learning style understands the problem by writing neatly and mentioning the information that is known and asked from the question, SV makes a problem-solving plan using existing information and knowledge of sequences and series, SV does not implement a problem-solving plan, can only get the value of the second term and do not know how to find the value of another term, SV does not re-check the answer. (2) subjects with auditory learning styles understand the problem by reading the questions repeatedly aloud but the SA is not good at understanding the questions because they are still wrong in writing the known information, the SA makes a problem-solving plan using existing information and knowledge of sequences and series, the SA carries out the plan troubleshooting but an error occurred in the end result, SA did not recheck the answer. (3) Subjects with a kinesthetic learning style understand the problem by practicing using their hands and then writing and mentioning the information that is known and asked from the problem, SK makes a problem-solving plan using existing information and knowledge of sequences and series, SK implements a problem-solving plan properly and correctly, SK rechecked the answers

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 a description of students' abilities in solving HOTS (Higher Order Thinking Skill) Type Number Pattern Problems Based on the Mathematics Ability of Class VIII B SMP IT (Integrated Islam) Qurrata A'yun Palu. This research is descriptive with a qualitative approach based on the problem-solving steps put forward by Polya. The results showed that subjects with high-level thinking skills and moderate-level thinking skills in solving mathematical problems with number patterns were as follows: (1) in understanding the problem, students with high-order thinking skills and moderate-level thinking skills demonstrated an understanding that was relevant to gathering information. The information contained in the problem can identify the problem of the problem with knowledge of the sentence "statement". (2) in planning problem solving, high-level ability subjects can plan a good strategy to achieve the goals in a problem and can choose relevant information from the problem. Meanwhile, subjects with moderate ability are quite good at planning problem solving however formulating a strategy is still not appropriate to be able to solve the problem properly. (3) in carrying out a problem-solving plan, subjects with high levels of ability are very good at executing, and carrying out planning and are able to organize and integrate problems with relevant prior knowledge, as well as subjects with moderate levels of ability (4) in re-examining, high subjects re-examining because it can monitor, check or detect the final results and unexpected events. Meanwhile, subjects with moderate ability did not re-examine because they felt unsure about solving the problems they were doing.   Keywords: ability analysis, HOTs type questions, learning outcomes, response quality, number patterns

Abstract

The 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.
