Abstract

This research aims to obtain students' mathematical communication profile in solving story problems of three-variable linear equation system. This type of research is descriptive research with a qualitative approach. The research subjects consisted of 3 students each with high, medium and low abilities. Data were collected using 2 techniques, namely written task and interviews. Indicators of mathematical communication in this research use indicators of mathematical communication according to NCTM. The results showed:  (1) in indicator of expressing mathematical ideas through writing and spoken, MRH and NNP subjects wrote and explained the example and how to form a linear equation of three variables. While HFK only explained the example. HFK also wrote and explained how to form a linear equation of three variables; (2) in indicator of understanding, interpreting, and evaluating mathematical ideas in writing and spoken, MRH and NNP subjects wrote and explained the steps of solving the problem correctly, while HFK was incomplete in writing and explaining it. MRH and NNP wrote and mentioned the conclusion according to what was asked in the problem, while HFK did not write or mention it; (3) In indicator of using mathematical terms, symbols and structures to model mathematical situations or problems, MRH, NNP and HFK used mathematical symbols and structures in writing example, equations and problem solving steps.

Abstract

This study aims to describe the critical thinking of class students. IX SMP Negeri 1 Tomini in sloving problems on the material of linear equations straight. The subject in this study were 3 students of class IX A of SMP Negeri 1 Tomini which has a category of students with high mathematical abilities, students with moderate mathematical abilities, and students mathematical abilities lo. This type of research is descriptive research with a quantitative approach, qualitative. This research instrument consists of the main instrument, namely the researcher it self in the supporting instruments in this research are writtten test and interview. The results of this study indicate that DTA and RM completed straight line equation questions by fulfilling all critical thingking criteria starting from the focus, reason, inference, situation, clarity and overview indicator, but DTA and RM have different thingking activities, namely DTA or subject have higt mathematical abilities in completing tasks with solutions which is longer with careful though. While RM or subject low mathematical ability in completing task with solutions in a more concise manner. This is supported by answer data written and interview. While T or subject with mathematical abilities low in completing the task in a very short way, but T fulfilles 5 critical thingking criteria starting from the focus, reason, situation, clarity, and overview indicators. But T does not meet one indicator, namely inference because T cannot conclude the final answer.

Abstract

This research aims to obtain a description of the profile of solving HOTS questions on prism volume material by class VIII students at SMPN 2 Kasimbar based on Polya's steps. This type of research is qualitative research. The subject in this study consisted of one student with high mathematical ability (DA) who was selected from the results of a grouping based on his mathematical ability, then the subject was willing and able to communicate well and was recommended by the mathematics teacher at the school. The results of the research show that the HOTS problem solving profile of high ability (DA) students in solving HOTS volume prism problems is: 1) at the stage of understanding the problem, the DA subject writes down what is known and is asked in the question based on the information he obtained in the question, 2) makes a plan , the DA subject prepares a plan by linking the knowledge he has and the information he obtains to the problem, so that the DA subject prepares a solution plan correctly. 3) carry out the plan, the DA subject carries out the solution plan according to the plan and uses his numeracy skills to get the correct answer. 4) at the stage of re-checking the answer, the DA subject re-checks the answer by carrying out proof and also making a conclusion at the end of the proof. So that DA meets the four indicators that have been presented.

Abstract

This study aims to Getting a description of errors and factors that cause errors in doing UAS for grade VIII students of SMPN 2 Galang, knowing the teachings of 2023-2024. This research is a descriptiveresearch with a qualitative approach. The subject of this study is to take 12 students of grade VIII SMP N 2 GALANG based on the value of UAS results under the KKM and teacher recommendations that can represent the answers of other students' mistakes. The researcher selects the subject by looking at the results of the student's final semester exam. Values that are below the MMC (minimum completeness criteria) will be analyzed for errors. The standard of KKM scores set at school is 75, so that students' UAS scores that are less than 75 are analyzed for errors. The results of this study show the types of mistakes made by grade VIII students of SMP N 2 Galang based on Newman's procedure: (1) errors in understanding. (2) errors in transforming, (3) errors in process skills, and (4) errors in writing the final answer. Factors that cause errors: (1) lack of students' understanding of the material that has been taught. (2) mastery of basic mathematical skills in the form of weak mathematical computing. (3) lack of understanding of concepts that make students easily forget the material that has been learned. (4) the learning model is not optimal, so that students still have difficulties in learning mathematics and tend to consider mathematics as a difficult and confusing subject.

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.
