Mathematics is an exact science that equips students with critical, strategic, creative, and analytical thinking skills so that mathematics needs to be given to students starting from elementary school. In learning mathematics, one of the learning objectives is to communicate ideas with symbols, tables, diagrams, or other media so that mathematical communication skills are needed to be possessed by students. The purpose of this study was to compare the mathematical communication skills taught using a project-based learning model and a Think Pair Share cooperative learning model. The sample of this study was class VIII-4 and VIII-9 at One of Medan's Junior High Schools, totaling 50 students. This study uses experimental research which shows the results of the research that the mathematical communication ability of project-based learning models has a higher average of 63.02 compared to mathematical communication skills using the Think Pair Share type of cooperative learning model which has an average of 52.13. The average value of the mathematical communication ability test obtained through giving the posttest at the end after being given treatment. So it is proven that the mathematical communication ability using project-based learning model is higher than the Think Pair Share type cooperative learning model.

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.
