Abstract

Mathematical creative thinking skills are essential competencies that need to be developed in students. This study aims to analyze students' mathematical creative thinking abilities in solving open-ended problems based on Silver’s indicators. A descriptive qualitative approach was used, involving fifth-grade students from SD Bruder Melati, categorized by their level of ability high, medium, and low. Data were collected through written tests (open-ended questions), interviews, and observations. The data analysis involved data reduction, data presentation, and drawing conclusions. The results showed that the fluency aspect had the highest percentage, followed by flexibility and originality. High-ability students were more confident in trying various problem-solving strategies and demonstrated better thinking flexibility. Medium-ability students tended to rely on known patterns before attempting their own alternatives, while low-ability students struggled with all aspects of creative thinking. The findings suggest that while students are capable of generating multiple solutions, they still face challenges in applying diverse strategies and producing unique solutions.

Abstract

A strong grasp of mathematical concepts is fundamental for developing problem-solving abilities. Yet, many fifth-graders struggle to master fraction operations, particularly addition and subtraction. This research investigates the efficacy of the Contextual Teaching and Learning (CTL) model in enhancing students' conceptual mastery of mathematics. Utilizing a quasi-experimental quantitative design, the study was implemented at SDN 1 Number Sari, with participants selected via cluster random sampling—12 students in the experimental group and 16 in the control group. Data were gathered through conceptual understanding assessments and documentary analysis. The t-test revealed statistically significant outcomes (p= 0.017), while the effect size (d= 0.83) indicated a substantial practical impact, classifying CTL as highly effective. These findings demonstrate that CTL not only achieves statistical significance but also delivers meaningful educational improvements. Thus, CTL proves to be a powerful pedagogical strategy for advancing fifth-grade students’ comprehension of fractional operations.

Abstract

This study aims to analyze a collection of previous research through a meta-analysis that investigates the effect of using digital-based learning media on students' critical thinking skills. This analysis is important because many students still exhibit limitations in critical thinking abilities. The articles included were obtained using Publish or Perish 8 with publication years ranging from 2015 to 2025, resulting in 23 data points from 21 selected articles. Several moderator factors considered in this meta-analysis include educational level, year of publication, and source of publication. The results regarding the influence of digital-based learning media on students' critical thinking skills are as follows: (1) there is a significant overall effect with an effect size (ES) of 1.086 (categorized as high); (2) the effect is more effective when used at the elementary school level or equivalent (ES = 1.7396, high category) based on educational level; (3) the influence is greater in the post-COVID-19 period (ES = 1.1504, high category) based on year of publication; and (4) a greater effect is found in articles published in conference proceedings (ES = 1.3627, high category) based on publication source.

Abstract

Many students struggle to understand length measurement, especially when solving real-life story problems. This reflects weak mathematical connection skills. Furthermore, students’ reluctance to collaborate with peers indicates a low cooperative learning profile. To address this issue, this study examines the impact of the Team Games Tournament (TGT) cooperative learning model, supported by the traditional game gatrik, on students’ mathematical connection skills and cooperation profile. A sequential explanatory mixed-method approach was used. Data were collected through tests, questionnaires, observations, and interviews. Quantitative data were analyzed using t-tests, while qualitative data were examined using Miles and Huberman’s interactive model, combined with Yin’s time series analysis. The results show that the TGT model with gatrik significantly improves both mathematical connection skills and cooperative behavior. This study provides insights for teachers to strengthen students’ mathematical and social competencies and serves as a reference for future research on cooperative learning and contextual media in education.

Abstract

Students in mathematics education programs often face challenges that require strong self-belief and the ability to manage their own learning in order to achieve optimal academic performance. This study investigates the influence of self-efficacy and self-regulated learning on students’ Grade Point Average (IPK), focusing on three objectives: (1) the direct effect of self-efficacy on IPK, (2) the direct effect of self-regulated learning on IPK, and (3) the indirect effect of self-efficacy on IPK mediated by self-regulated learning. A quantitative approach with path analysis was employed, involving 40 Mathematics Education students selected through simple random sampling. Data were collected via validated and reliable questionnaires, and analyzed using SPSS and SMART-PLS v.4. The results indicate that the direct influence of self-efficacy on IPK is weak and statistically insignificant. In contrast, self-regulated learning shows a significant and meaningful direct effect on IPK. Furthermore, self-efficacy strongly influences self-regulated learning, which in turn positively affects IPK, confirming an indirect relationship. It is concluded that fostering both self-belief and regulatory learning strategies is essential to improving academic outcomes in higher education.

Abstract

Students' low numeracy skills in understanding integer concepts often lead to misconceptions that frequently undetected, as they are embedded within students' cognitive processes rather than solely visible in final answers. This study aims to detect students' misconceptions in integer topics by analyzing their thinking processes using Mason's framework, based on their numeracy levels. This research employed a descriptive qualitative approach, involving six seventh-grade students from class VII at MTsN 8 Muaro Jambi. The subjects were classified into three numeracy categories: high, medium, and low. Data were collected through think-aloud-based diagnostic tests, in-depth interviews, and observations during problem-solving sessions. Data were then analyzed using Mason’s stages of thinking. The results showed that all students experienced theoretical and correlational misconceptions, while classification misconceptions were found only among students with low numeracy levels. Most errors occurred in the attack and review stages. Mason’s thinking framework proved effective in systematically identifying the location and type of misconceptions and provides a foundation for designing more targeted and responsive numeracy-based instructional strategies.

Abstract

Problems experienced by students include low understanding of mathematical concepts and lack of learning motivation. This study aims to examine the extent to which the Think Pair Square (TPS) cooperative learning model can be a solution to improve both aspects. This study design is a quasi-experimental study with two groups: an experimental group and a control group. Data were collected through a mathematical concept understanding test and a learning motivation questionnaire. Data analysis was carried out using a paired t-test, N-Gain calculation, and descriptive analysis using a Likert scale. The results of the study showed a significant increase in the understanding of mathematical concepts and learning motivation of students in the experimental group. The application of collaborative learning strategies has been proven to help students build a deeper understanding of concepts and increase their engagement in the mathematics learning process.
