Abstract

This study aims to analyze the effectiveness of implementing the Problem-Based Learning (PBL) model with a contextual approach in improving students’ mathematical creative thinking skills. This research employed a pre-experimental design using a one-group pretest–posttest approach involving 30 eighth-grade students in Yogyakarta, selected through purposive sampling techniques. The research instruments consisted of a creative thinking skills test and observation sheets. The results showed a significant difference between students’ pretest and posttest scores based on the paired-sample t-test (p-value = 0.0001 0.05). Furthermore, the one-sample t-test results indicated that the average creative thinking ability of students had reached the predetermined mastery criteria (p-value = 0.0001 0.05). The proportion test also demonstrated that classical learning mastery was achieved (p-value = 0.010 0.05), with at least 75% of students reaching the mastery criteria. Thus, it can be concluded that the integration of the PBL model with a contextual approach is effective in enhancing students’ mathematical creative thinking skills and supports active engagement in learning

Abstract

The purpose of this study was to describe the mathematical concept understanding of ninth-grade junior high school students in solving problems involving quadrilaterals. A quantitative descriptive method was used on a sample of 38 students. The research instrument consisted of an essay test based on indicators of concept understanding, including the ability to verbally restate concepts, classify objects, and present concepts in various forms of mathematical representation. The research results showed that students’ mathematical conceptual understanding fell into the moderate category with an average score of 72. Based on the grouping results, there were 11 students in the high category, 20 in the moderate category, and 7 in the low category. Students in the high category met most of the indicators, while students in the moderate and low categories still experienced difficulties, particularly with the mathematical representation indicator. Overall, students’ mathematical concept understanding was not uniform, so learning efforts are needed that place greater emphasis on strengthening concept understanding.

Abstract

Mathematical reflective thinking is an essential ability that enables students to understand problems, connect prior knowledge, evaluate solution strategies, and justify their conclusions. This study aims to analyze high school students’ mathematical reflective thinking ability in solving three-variable linear equation word problems. This research employed a descriptive method with a qualitative approach supported by quantitative descriptive analysis. The subjects were 33 eleventh-grade students from a senior high school in Karawang Regency. Data were collected through three essay questions designed based on three indicators of mathematical reflective thinking: reacting, comparing/elaborating, and contemplating. The results showed that students’ mathematical reflective thinking ability was not yet fully developed. Based on the categorization, 9.1% of students were in the high category, 72.7% were in the medium category, and 18.2% were in the low category. The analysis of students’ responses indicated that students were generally able to identify some information in the problems, but many still experienced difficulties in constructing mathematical models, selecting appropriate solution strategies, and verifying the correctness of their answers. These findings suggest that students need learning activities that encourage deeper reflection, systematic problem solving, and evaluation of mathematical reasoning.

Abstract

The fishing activities carried out by traditional fishermen involve various mathematical concepts that develop contextually through daily cultural practices. However, these mathematical concepts are often not optimally integrated into formal education, leading to mathematics being viewed as abstract and disconnected from real-life situations. This study aims to describe and analyze the mathematical concepts applied by fishermen in their fishing activities. This study employs a qualitative method with an ethnographic approach. The research participants are fishermen at Pamayangsari Beach, Cipatujah Subdistrict, Tasikmalaya Regency, selected through purposive sampling based on their experience and knowledge in fishing activities. Data were collected through observation, semi-structured interviews, and documentation, with the researcher serving as the primary instrument, supported by interview guidelines, observation checklists, and documentation guidelines. Data analysis utilized the Miles and Huberman interactive model, which includes data reduction, data presentation, and drawing conclusions. The research findings revealed several mathematical activities performed by the fishermen, namely counting, measuring, locating, and explaining. Counting activities were observed in calculating fuel requirements and distributing the catch. Measuring activities were found in measuring sea depth, determining mesh size, boat cargo capacity, and estimating tides. Locating activities were evident in determining the direction and position of nets using natural landmarks, while explaining activities were reflected in the fishermen’s ability to describe the fishing process in a sequential and logical manner. The research findings indicate that mathematical concepts develop contextually within the cultural practices of fishermen and have the potential to support mathematics learning based on local culture.

Abstract

Students' low ability to solve contextual mathematical problems is often influenced by affective factors, one of which is self-efficacy. This study aims to determine the effect of self-efficacy on students' mathematical problem-solving ability based on Newman's stages. The research approach used was quantitative with a causal-associative method. The sample in this study consisted of 31 students. The research instruments consisted of a self-efficacy questionnaire and a mathematical problem solving ability test. Data analysis techniques included prerequisite tests and hypothesis testing using the t-test and the coefficient of determination. The analysis results showed a significant value of 0.010 0.05, so it can be concluded that there is a significant influence of self-efficacy on students' mathematical problem-solving ability, namely 20.7%.
