This study aims to analyze the effect of the Realistic Mathematics Education (RME) approach on the mathematical problem-solving abilities of elementary school students. RME is a learning approach that connects mathematical concepts with real situations that students can find in everyday life. The research method used is qualitative research by reviewing the results of previous studies that are relevant in the context of mathematics learning in elementary schools. Based on the analysis of various studies, the results of the study indicate that the application of RME can improve students' mathematical problem-solving abilities. This is evident in various materials such as geometry (circumference and area of ​​trapezoids and kites), mixed arithmetic operations, and equivalent fractions. RME also plays a role in increasing students' self-esteem and self-efficacy in learning mathematics, which in turn strengthens their motivation and performance. In addition, the learning media used in RME, such as geoboards, can enrich students' learning experiences and facilitate understanding of mathematical concepts in a more concrete way. This study provides an overview that RME not only improves students' cognitive abilities, but also supports their emotional and social development in the context of mathematics learning.

Mathematics plays a crucial role in developing students' problem-solving abilities and independence. Educators need to consider the varying characteristics of students when it comes to solving problems, one of which is their adversity quotient (AQ) level. The adversity quotient relates to a student's ability to handle complex problems or to overcome challenging situations. This research aims to analyze the mathematical problem-solving abilities of Class X students in the context of Systems of Linear Equations in Two Variables (SPLDV) based on their Adversity Quotient (AQ). This qualitative, descriptive study involved selecting research subjects using an AQ questionnaire and was conducted in Class X. Data collection methods included testing, interviews, and documentation. Data analysis techniques included data reduction, data presentation, and conclusion drawing. The results indicate that subjects with the Climber type can understand problems, develop problem-solving plans, solve problems with accurate and appropriate steps, and use available information to re-check their answers. Subjects with the Camper type can understand problems, develop problem-solving plans, solve problems with accurate and appropriate steps, but often cannot use available information to re-check their answers. Subjects with the Quitter type can understand the problem and formulate a plan but struggle to solve the problem accurately and appropriately, and tend not to use available information to re-check their answers.

This study investigates the impact of contextual problem-solving on students' mathematical reasoning abilities, comparing it to traditional problem-solving exercises. The study employs a quasi-experimental design with two groups: an experimental group exposed to contextual problem-solving activities and a control group using conventional methods. The experimental group demonstrated a 24% improvement in their mathematical reasoning abilities compared to the control group. Contextual problem-solving, which integrates real-world problems into the learning process, was found to be more engaging and effective in promoting deeper understanding and application of mathematical concepts. The study highlights the benefits of contextual learning in making abstract mathematical concepts more tangible and relatable to students. The findings suggest that by connecting mathematical knowledge to real-world scenarios, students develop stronger reasoning skills and improve their problem-solving capabilities. Moreover, the study recommends incorporating more contextual problem-solving exercises into curricula and providing teachers with training on how to implement these strategies effectively. It also suggests that future research explore the long-term effects of contextual problem-solving on other learning areas, such as critical thinking and creative problem-solving. This approach not only enhances students' mathematical reasoning but also fosters a more engaging and meaningful learning environment, thus preparing students to apply their mathematical knowledge in real-life situations.

This study investigates the relationship between mathematics self-efficacy and problem-solving ability, exploring the role of the Jigsaw cooperative learning model in enhancing both factors. Self-efficacy, defined as students' belief in their ability to successfully perform mathematical tasks, has been shown to significantly impact students' problem-solving capabilities. The research focuses on understanding how this belief influences academic performance and how the Jigsaw model, which fosters collaborative learning, affects students’ self-efficacy and problem-solving skills. A survey-based research design was employed, with participants consisting of university students enrolled in mathematics courses. Data collection involved administering a self-efficacy scale to assess students' confidence in solving mathematical problems and a problem-solving test to evaluate their abilities. Path analysis was used to determine the relationship between self-efficacy and problem-solving skills, and the effect of the Jigsaw model was evaluated by comparing pre- and post-test scores between the experimental and control groups. The results revealed a strong positive relationship between self-efficacy and problem-solving ability (β = 0.45). Additionally, the Jigsaw model significantly enhanced this relationship, improving both students' self-efficacy and problem-solving performance. These findings highlight the importance of fostering self-efficacy in mathematics education and the effectiveness of the Jigsaw cooperative learning model in achieving this goal. The study provides valuable insights into improving teaching strategies in mathematics, particularly for subjects requiring critical thinking and problem-solving skills, by promoting a more interactive and supportive learning environment.

The aim of this research is to obtain significant data and analyze the influence of the Team Assisted Individualization (T.A.I) learning model on the ability to solve mathematical problems on the subject of linear programming in class X students at MA Al Ittihad Sawangan Depok. The research method used is a quasi-experimental method (quasi-experiment). Sampling was carried out using a cluster random sampling technique with a research sample of 40 students, namely 20 students in class X IPS 2 as the experimental class and 20 X IPS 1 as the control class. The analysis technique used is a comparative analysis technique with the t-test, at a significance level of α= 0,05. The analytical requirements tests used in this research are the Chi-Square test for normality test and Fisher's test for homogeneity test. At a significance level of 0,05 with the Chi-Square test in the experimental class the price X2count <X2table (-33,38 < 9,488) while for the control class the price Homogeneity test at a significance level of 0.05 with Fisher's test, obtained F-count = 1,642 and F-table = 2,165 with a significance level of α= 0,05. Because Fcount < Ftable, H0 is accepted, so it can be concluded that the two classes have the same or homogeneous variance. Hypothesis testing uses the t-test with a significance level of α= 0,05. From the calculation results, t-count = 3,619, while ttable with degrees of freedom = 38 is 2,026, meaning t-count > t-table. Thus H0 is rejected and H1 is accepted. This research concludes that mathematical problem solving abilities using the Team Assisted Individualization (T.A.I) learning model are better than mathematical problem solving abilities using the Expository model.
