Abstract

This study aims to describe the problem solving ability of students with different mathematical abilities (high, medium, low) in solving ill structured problems of social arithmetic material. This research used a qualitative approach with descriptive research type. For the research subject, the researcher chose three seventh grade students at Labschool Unesa 2 Junior High School with different levels of mathematical ability (high, medium, low) and the same gender. Researchers used math ability tests, problem solving tests, and interviews to collect data. The mathematics ability test data was analyzed based on the range of student ability grouping Ratumanan and Laurens (2006), the problem solving test data was analyzed using Polya's problem solving ability indicators, and the interview data was analyzed using data triangulation (data reduction, data presentation, conclusion drawing). The results show that students with high mathematical ability have analyzed the problem well because students can consider all solutions to the problems given and the assumptions made by students are relevant to real life. Students have also entered the category of good problem solving skills. Meanwhile, students with medium and low mathematics ability have not been able to analyze the problem well because students only think of part of the solution to the problem given and the assumptions made by students are not relevant to real life. Students with moderate mathematical ability fall into the category of fairly good problem solving ability. Then students with low mathematics ability fall into the category of poor problem solving ability. These results can be used as an evaluation in the learning process or a reference for further research.

Abstract

In the process of problem solving, a student will engage in the activity of thinking and connecting the information in his mind. One kind of thinking that can help the problem solving process and find the right solution is relational thinking. The aim of this research is to describe junior high school students relational thinking using cognitive styles field dependent and field independent in solving polyhedron problems. This research is qualitative descriptive research carried out in class VIII-B of Public Junior High School 1 Surabaya, even semester of the 2022/2023 academic year. This research was carried out on students who had received geometry material, especially regarding the volume of polyhedron. The subjects in this research were two students, namely students field dependent (FD) and field independent (FI) with equivalent mathematical abilities. This research used instruments in the form of the GEFT test, mathematics ability test, problem solving test, and interview guide. The results of this research show that field dependent and field independent students when understanding the problem, FD and FI students carry out relational thinking activities well, namely identifying the information that exists in understanding the problem given and explaining the relationship between the information in the problem and the knowledge that the students have. and related to the problem given. In the step of making a problem solving plan, FD and FI students can determine and choose the most suitable strategy for solving the problem according to the information known and the knowledge the students have. Next, FD and FI students can carry out problem solving plans. At this stage, FD students carry out problem solving according to the strategy and produce the right answer, while FI students experience errors in substituting values ​​and calculation errors to find the final result on each question. In the step of re-examining problem solving, FD and FI students can build connections between the answers and the problems given by making verbal conclusions regarding the results related to the answers to the problems given. The FD student's conclusion was correct, while the FI student's conclusion was incorrect because they experienced a calculation error in the previous stage. One of the causes of mistakes made by FI students is that FI students do not carry out activities to double-check the problem solving steps. Meanwhile, FD students carried out activities to double-check each step in solving the problem.

Abstract

Algebraic thinking is a mental activity that occurs within a person in using symbols, generalizing, formulating relationships between patterns and developing variable concepts in problem solving. This study aims to describe the algebraic thinking ability of junior high school students with male and female gender in solving relation and function problems. Researchers conducted an algebraic thinking ability test on two junior high school students in Surabaya with high mathematics ability based on the results of the mathematics ability test. The results showed that male and female students on the generalization indicator, can find information contained in the relation and function problems, and identify patterns based on the objects given systematically. Likewise, on the abstraction indicator, both students can express something that has no known value in algebraic form and make equations from the relationship between the objects given. In the dynamic thinking indicator, male and female students can predict the relationship between known values to determine the next value, but only female student can solve with two different alternative ways. On the organization indicator, male student can arrange the information obtained into a logical deduction strategy, while female student arrange the information in the form of a graph but are less precise to describe the problem situation and the relationship between the conditions of the overall problem. On the modeling indicator, only male student can state the problem into a mathematical model. Therefore, this research can be used as a consideration for teachers to familiarize students to find other ways of solving so that students will be skilled in thinking algebra by paying attention to differences in the algebraic thinking abilities of male and female students. In addition, further research needs to be done to examine subjects of moderate or low mathematical ability, to see differences in students' algebraic thinking skills because there may be differences in algebraic thinking skills between male and female students with moderate or low ability.

Abstract

Numeracy is essential for students to utilize their basic mathematical skills optimally and be more critical in receiving and processing information. However, facts in the field show that students still need help understanding the concept of numeracy. This research aims to describe junior high school students' numeracy in solving AKM questions with number content based on mathematical ability. This research uses a qualitative approach with a descriptive research type. For the research subjects, the researchers chose three class VII junior high school students with different levels of mathematical ability (high, medium, low) by paying attention to their communication skills. Researchers used TKM, numeracy tests, and interviews to collect data. The TKM was used as a reference to determine the analyzed research subjects based on the scoring guidelines. The numeracy test and interview results were analyzed using three stages of qualitative data analysis: data condensation, data presentation, and conclusion. The numeracy test results and video-recorded interviews were analyzed by taking important parts by coding them and then presenting them in figures and tables. The results of this study show that students with high mathematical abilities could fulfill the seven basic mathematical abilities in completing the numeracy test. Students with moderate mathematics abilities only fulfilled six basic mathematics abilities in completing the numeracy test. The basic mathematical abilities that cannot be fulfilled were the ability to use language and symbolic operations because students make calculation errors. Then, students with low mathematics ability could only fulfill some numeracy indicators to solve the problem. Students with low mathematical abilities needed help communicating the process of solving writing or orally. Students could not change the context of the mathematical model and did not change the information or equations presented. In completing the numeracy test, students with low mathematical ability could not make patterns and relationships and made calculation errors.

Abstract

This research aims to describe the mathematical reasoning of junior high school students with visual, auditory, and kinesthetic learning styles in solving SPLDV problems. This research used a qualitative descriptive approach. The subjects of this study were three junior high school ninth-grade students with different learning styles (visual, auditory, and kinesthetic), high equivalent mathematics ability, and the same gender. The results showed that the three students' mathematical reasoning in understanding the problem included explaining the problem in their own words, identifying all known information, stating the sufficiency of information, and representing the problem in mathematical form, accompanied by reasons. Visual students identified all questions, while auditory and kinesthetic students only had most of them, accompanied by reasons. In making plans, all three students compiled strategies involving concepts accompanied by reasons. All three students applied the strategy in implementing the plan and gave reasons at each step. In re-examining, all three students evaluated the correctness of the solution accompanied by reasons, but auditory students did not perform a final check. Kinesthetic students draw conclusions thoroughly, while visual and auditory students only cover part of it, accompanied by reasons. Through this research, teachers can design learning strategies to optimize students' mathematical reasoning in solving SPLDV problems.

Abstract

This purpose of this study is to describe students' written and oral mathematics communication abilities in solving probability problems based on their learning styles. This research uses a qualitative approach with qualitative description research methods. The subjects of this study were three ninth grade junior high school students with different learning styles (visual, auditory, and kinesthetic), equivalent mathematical ability, and the same gender. Data were collected from learning style questionnaires, mathematics ability tests, mathematical communication ability tests (both written and oral), and interviews. The mathematical communication ability test was analyzed using the mathematical communication ability indicators from Nurhasanah et al. (2019). The results of the study showed that in written mathematical communication, students with visual, auditory, and kinesthetic learning styles met four indicators: expressing a problem in mathematical ideas, expressing a problem in mathematical models, solving problems in an organized and structured way, and evaluating mathematical ideas. The difference is that visual students do not write what is asked but explain it through interviews, auditory students do not make a problem-solving plan, and there are inaccuracies in problem-solving among visual and kinesthetic students. In oral mathematical communication, students with visual, auditory, and kinesthetic learning styles met four indicators: expressing a problem in mathematical ideas, expressing a problem in mathematical models, solving problems in an organized and structured way, and evaluating mathematical ideas. The difference is that auditory students do not explain the information that is asked directly but rather through interviews. The benefits of this study can be used as a basis for designing teaching strategies that can improve students' mathematical communication abilities and to further develop future research.
