To improve students' mathematical reasoning abilities, it is of course important to look at cognitive and affective aspects together, to see more broadly whether affective factors play an important role in mathematical reasoning abilities. This research aims to determine the differences in self-efficacy between male and female genders, differences in mathematical reasoning abilities between male and female genders, and the influence of self-efficacy on students' mathematical reasoning abilities in terms of gender. The research method used in this research is a correlational method with an ex post facto research design. The population of this study were all class VII students at SMP Negeri 20 Tasikmalaya. The sample in this research was obtained using non-probability sampling with a purposive sampling technique from the existing population. Classes VII-B, VII-C, VII-D, VII-E were selected as sample classes with a total of 102 students. The data collection technique is by giving a mathematical reasoning ability test and a self-efficacy questionnaire. The data analysis techniques used are descriptive statistical analysis, independent sample t-test, and two way ANOVA. Based on data processing, data analysis, and hypothesis testing, research results showed that (1) There are differences in self-efficacy between male and female genders, (2) There are no differences in students' mathematical reasoning abilities between male and female genders, (3) There is no influence of self-efficacy on students' mathematical reasoning abilities in terms of gender. These findings certainly show that affective aspects do have a role in determining students' abilities, but of course some affective aspects have a significant role, some only influence a small part.

Students in class VII still have difficulty solving contextual problems related to the concept of a square. Through research, it will be shown that Realistic Mathematics Education(RME) and expository are more effective if it is based on students' post-test results after studying the concept of a square. The research objectives were achieved using a quasi-experimental method involving 2 groups of subjects, namely an experimental group of 33 students and a control group of 34 students. The subject group came from the class VII population at one of the junior high schools in Kebumen. The data analyzed is in the form of final semester exam results and posttest results collected using a test instrument in the form of 10 multiple choice questions. The data were analyzed using balance tests, normality tests, homogeneity tests, and effectiveness tests. Based on the results of the t-test and the hypothesis determined by the researcher, it can be shown that the application of the Realistic Mathematics Education(RME) method is more effective than the expository method. This conclusion is also strengthened by the mean value of the experimental group which is higher than the control group.

Project Based Learning (PjBL) approach encourages students to be more active, independent, and creative problem solvers, thereby fostering character values such as creativity and curiosity. This research applies the Systematic Literature Review (SLR) method to examine the PjBL model in mathematics education at the junior high school level. PjBL as a learning model involves teachers acting as facilitators who present students with project-based problems to solve independently. This approach stimulates students to design processes and frameworks to find solutions to given problems. The study focuses on various mathematical topics including Flat-Sided Spatial Structures (Cube, Rectangular Prism, and Prism), Curved-Sided Spatial Structures (Sphere, Cylinder, Cone), Quadratic Functions, Trigonometry, and Systems of Linear Equations with Two Variables (SLETV). The analysis concludes that the PjBL model enhances mathematical learning by promoting product-oriented learning, student-centered approaches, fostering critical thinking and real-life problem-solving skills, as well as encouraging collaborative abilities and competition among peers. These findings underscore the effectiveness of integrating PjBL into mathematics education and highlight its implications for fostering holistic student development.

This study aims to analyze the difficulties students face in solving problems related to proportional comparison. This study employs a case study method based on the errors made by students in solving problems related to proportional comparison. Four students were selected as a theoretical sample from a group of 34 seventh-grade students at the junior high school in Tasikmalaya. These students were chosen due to their complex levels of errors, which included procedural errors, incomplete solutions, and mistakes in determining mathematical formulas. The results of the study indicate that students experience difficulties in solving proportional comparison problems, including: (1) difficulty in understanding mathematical language, (2) difficulty in understanding word problems, (3) the influence of mathematics anxiety, and (4) differences in learning styles. Interviews and classroom observations revealed that factors such as less varied teaching methods, a lack of contextual practice, and low learning motivation contribute to the difficulties experienced by students. The discussion of the research results emphasizes the importance of more interactive and contextual teaching approaches to enhance students' understanding of the concept of proportional comparison. The implications of this study highlight the need for the development of more innovative teaching materials and the use of educational technology to help students overcome these difficulties.

The development of creative thinking skills in problem-solving is crucial, especially in mathematics at the elementary school level. This study aims to investigate the relationship between the use of Genially learning media and the creative mathematical thinking abilities of fifth-grade students at SDN Sunter Jaya 03 Pagi. Employing a quantitative approach with a correlational design, the study involved all fifth-grade students as the sample. Data were collected through a creative thinking skills test and a questionnaire analyzing the use of Genially. The results indicate that Genially was engaging for students (84%), but they faced language comprehension difficulties (70%). The creative mathematical thinking test revealed that the fluency indicator had the highest percentage (81.5%), while the originality indicator had the lowest (40.5%). Pearson correlation analysis showed no significant relationship between the use of Genially media and students' creative mathematical thinking abilities, with a significance value of 0.731 and a Pearson Correlation of 0.072. These findings suggest that while Genially may be engaging, it does not significantly enhance creative mathematical thinking on its own. The study implies the need for further guidance from teachers in using Genially media to optimize students' creative potential and enhance their understanding of the learning material. This highlights the importance of integrating instructional support with technological tools in the learning process.
