Mathematics education in Indonesia faces significant challenges, as reflected in the low performance of students in various international assessments. Traditional teaching methods, which are less interactive, are considered one of the key factors contributing to students' low problem-solving abilities in mathematics. This meta-analysis aims to evaluate the impact of Polya's heuristic model on students' mathematical learning outcomes and determine the extent to which this strategy can enhance students' learning abilities compared to conventional teaching methods. The study employs a meta-analytic approach, integrating data from 15 primary studies conducted between 2014 and 2023, and uses statistical analysis to calculate the average effect size of the implementation of Polya's heuristic model in mathematics education. The findings reveal a significant improvement in students' mathematical learning outcomes using Polya's heuristic model, with an average effect size of 1.13, categorized as "very high." The study suggests that the application of Polya's heuristic model is significantly more effective in enhancing students' mathematical learning outcomes than conventional teaching methods. The practical implication is that educators and policymakers in Indonesia could consider adopting this strategy in curricula and teacher training programs to improve the quality of mathematics education.

One of the psychological aspects of students that encourages students' mathematical representation abilities is self-efficacy. This article is a Systematic Literature Review (SLR) of 22 research published until October 2022 with the help of the Publish or Perish (PoP) application with the Scopus, and Google Scholar databases. SLR can be useful for finding research gaps from previous research. This article aims to; (1) investigate the period, index, research approach, subject matter, and subject demographics heterogeneity from 22 inclusion articles, (2) description of mathematical representation abilities in terms of self-efficacy, and (3) learning methods/approaches/strategies that can enhance self-efficacy, as well as the ability of mathematical representation. The results of the SLR research show that students with low self-efficacy have limitations in mathematical representations such as the majority involving a single representation, difficulty understanding the meaning of the questions, and lack understanding of material concepts. The ability of students' mathematical representation with moderate levels of self-efficacy experienced several problems such as difficult to solve problems, less accurate calculations, and dominantly showed moderate mathematical representation abilities. Meanwhile, students with dominant high self-efficacy also show high mathematical representation abilities. For future researchers, it is recommended to conduct research on this topic at the elementary school level, research locations outside Java Island, as well as trigonometry material.

Preliminary observation results highlight the importance of utilizing innovative learning media to stimulate students' creativity in both classroom and home-based learning. One interactive learning medium identified for this purpose is GeoGebra Classroom. This research aims to analyze the effect of using the GeoGebra Classroom on the increment of students’ creativity, the effect of the increment of students’ creativity on students’ learning Results, the effect of GeoGebra Classroom quality on students’ learning Results, and the interactivity between students’ creativity and the quality of GeoGebra Classroom learning media. By analyzing pre- and post-implementation learning processes with GeoGebra Classroom, we collected data on increased student creativity. In conclusion, GeoGebra Classroom effectively fosters increased student creativity. And from the process of analyzing the effect of students’ creativity increments, we get the result that the creativity increments give an effect on the learning result of quadratic function materials. Unfortunately, the quality of the learning media GeoGebra Classroom can’t give an effect on the learning result. The insights gained pave the way for future research efforts to delve deeper into the optimization of interactive learning media to improve educational outcomes in a variety of academic contexts.

Mathematics research often focuses only on students' learning outcomes without considering their emotional aspects. This study aims to describe the tendency of students' sentiment toward mathematics in general and partially based on mathematics learning outcome groups, namely high, medium, and low. In addition, a mood analysis was conducted using Ekman's Basic Emotion classification. Data collection techniques are questionnaires and documentation. The questionnaire contains open questions about students' opinions on mathematics and closed to queries for student demographics. Documentation is done by collecting test scores from student grade books. This study used a descriptive method with data in the form of 72 comments from grade XI high school students in Bandung City, which were analyzed using the Orange Application Sentiment Analysis. The results of the study showed that (1) student sentiment was generally dominated by positive sentiment at 72.22%, (2) positive sentiment also dominated the groups of students with high, medium, and low learning outcomes, with a percentage of more than 68%, and (3) the results of the classification of emotions based on Ekman's Basic Emotion indicated that "joy" was the most dominant emotion, while "anger" had the lowest frequency of occurrence. This study provides new insights regarding students' emotional aspects in mathematics learning, which can be used to improve teaching strategies.

The mathematical literacy skills of Indonesian students, as reflected in the PISA results, continue to be a concern because of their poor performance. Students with high mathematical disposition and high self-efficacy are often more proficient in mathematical literacy. This study aimed to examine how mathematical disposition and self-efficacy affect students’ mathematical literacy skills. This study employed a quantitative approach with a nonexperimental design and adopted a causal associative methodology. Data collection involved administering mathematical disposition and self-efficacy questionnaires, along with a mathematical literacy test, to 56 junior high school students. The analysis was performed using structural equation modeling-partial least squares (SEM-PLS) in the JASP 0.18.3.0 application. The results showed that mathematical disposition significantly enhances both self-efficacy and mathematical literacy skills. Conversely, while self-efficacy positively influenced mathematical literacy skills, the effect was not statistically significant.
