Abstract

This study aims to analyze students' reflective thinking skills in solving story problems on kite material reviewed from Visual, Auditory and kinesthetic learning styles. The method used in this study is descriptive qualitative. The subjects in this study were 15 students of grade VII of Bukambero Private Middle School. The subjects of the study were selected by purpose sampling by looking at the criteria for high, medium and low reflective thinking ability categories for each learning style. The object of this study is students' mathematical reflective thinking skills in solving story problems on kite material reviewed from learning styles. The data collection techniques used were Questionnaires/learning style questionnaires, reflective thinking ability tests, and interviews. Data analysis techniques used data reduction, data presentation and drawing conclusions. The results of the study using reflective thinking indicators showed that students with visual learning styles and students with Auditory learning styles were only able to meet the Reacting and comparing indicators, so this subject had moderate reflective thinking skills. while students with kinesthetic learning styles were able to meet all the Reacting, comparing and contemplating indicators. So it can be stated that students with kinesthetic learning styles have high reflective thinking skills compared to visual and auditory learning styles.

Abstract

This study aims to analyze the mathematical problem-solving abilities of seventh-grade students at SMP Kristen Palla on the topic of algebraic expressions using the Problem Based Learning (PBL) model. This research employed a qualitative descriptive approach involving 20 student participants. Data were collected through problem-solving tests and interviews based on Polya's problem-solving steps: understanding the problem, devising a plan, carrying out the plan, and reviewing the result. Data analysis techniques using the Miles & Huberman model, namely; data reduction, data presentation, and drawing conclusions. The results showed that 10 students (50%) demonstrated high problem-solving abilities and achieved mastery, 6 students (30%) were in the medium category, and 4 students (20%) were in the low category. Based on the minimum mastery criterion (KKM) set at 75, 10 students (50%) met the standard, while the other 10 (50%) did not. The PBL model effectively supports students in developing critical thinking and problem-solving skills, making learning more meaningful and contextual. This study is expected to serve as a reference for teachers in implementing effective instructional strategies to enhance students' mathematical problem-solving abilities

Abstract

This research aims to evaluate the understanding of seventh-grade students at Rangga Rame Private Junior High School regarding mathematical concepts, particularly those related to algebraic expressions. Three seventh-grade students were selected for this qualitative descriptive study based on their conceptual knowledge test results. The ability levels of the three students are categorized as high, medium, and poor. Data collection techniques used structured interviews and tests. Data analysis techniques involved data reduction, data presentation, and data conclusion. The research results show that the differences in students' understanding of mathematical concepts result in grouping students into three levels. The indicators of conceptual understanding found include: the ability to explain concepts both verbally and in writing; grouping objects based on certain criteria; applying concepts procedurally; connecting concepts to solve problems; and presenting concepts in various representations, including graphs, tables, and diagrams. Eighteen students participated in the test; six of them were in the high group, four in the medium group, and the remaining six in the low group. The low level of knowledge is caused by several factors, including a lack of understanding of the questions, rushed answers, and inadequate mastery of the subject matter during the learning process.

Abstract

This study aims to determine student errors clearly VII SMPK St. Paul Karuni in solving HOTS-type math problems on set material. This type of research is descriptive with a qualitative approarch. Data analysis techniques use steps consisting of 3 steps, namely: data reduction, data presentation, and drawing conclusions. Based on the results of the study, it can be concluded that the types of errors that arise when students solve the set material story problem are 1) errors in understanding the problem, where students do not complete writing down what is known in the question and does not write down what is known and what is asked in the question. 2) transformation error, where students cannot change the problem from story form to mathematical form and do not complete the solution. 3) Process skill errors, where students are unable to perform calculations. 4) Errors in writing the final answer, where students write the final answer that does not match in the question.Factors in students that cause student errors are not having the ability to write down things that are known and asked in the problem, rushing to solve the problem, not having the ability to do the correct solution, and not understanding the calculations used.

Abstract

The purpose of this research is to find out the ethnomathematics in the traditional house of Tago'o Village, North Wewewa District and its introduction in learning at SMA Negeri 1 North Wewewa. This research adopted qualitative and exploratory methods with research subjects consisting of traditional leaders, hosts, and traditional house builders in Tago'o Village. The results revealed several findings related to traditional houses in Tago'o Village, such as the trapezium on the front view of the traditional house tower, the triangular shape seen from the side, and the concept of intersecting lines called karaga umma. The structure of the traditional house shows the use of wood that forms horizontal and intersecting lines, with the pillars of the traditional house forming vertical and perpendicular lines. In addition, the study also identified various geometric shapes such as blocks, rectangles, squares, circles, tubes, spheres and acute angles found in various parts of the traditional house, from the inside such as food storage to the outside such as under the house for pets. These findings provide an overview of the use of mathematical concepts related to the design and structure of the traditional houses of Tago'o Village. The implication is that this knowledge can be applied in the context of learning at SMA Negeri 1 Wewewa Utara to enrich students' understanding of mathematics in everyday life based on local wisdom.
