Mathematical anxiety and self-concept are factors that influence students' mathematics learning outcomes. Therefore, this research aims to determine the influence of mathematical anxiety and self-concept on the mathematics learning outcomes of class VIII students at MTs Miftahul Ula partially and simultaneously—a type of ex post facto research with a quantitative approach. The population in this study consisted of all VIII class students at MTs Miftahul Ula for the 2023/2024 academic year, totaling 70 students consisting of 2 classes. The sampling technique is carried out using a saturated sampling technique, namely a sampling technique where all members of the population are used as samples without giving each element or member of the population the same opportunity to become a sample. Based on the results of data analysis, it was found that the significant value for mathematical anxiety was and the significant value for self-concept was . The mathematical anxiety factor only partially influences students' mathematics learning outcomes. Meanwhile, based on the F test, the value was three, and the significant value was . So, there is an influence between mathematical anxiety and self-concept on students' mathematics learning outcomes.

This research aims to find the range of minimum mathematics scores for a madrasah aliyah in Serang City. The research population was 888 students, and the sample size was 151 people, with the characteristics of the respondents being 46 men and 105 women. This sample was taken using a convenience sampling technique, namely madrasah aliyah students who had mastery of mathematics material and grades. The research data were analyzed using conjoint analysis and the Wastendorp price sensitivity test. Based on the optimal price point, a value of 76 is a mathematical value that is neither too low nor too high to achieve. Based on the acceptable price range, the minimum value range students consider to have mathematical ability is 73 to 80. Based on the indifference price, a value of 78 is considered ideal because this is a value that is considered neither low nor high to be achieved. The mathematics scores displayed by students can know, understand, and analyze mathematical problems in everyday life in the fair or even good category. Students are also expected to be polite, caring, confident, honest, disciplined, and responsible. When interacting with the community, students can demonstrate religious attitudes such as gratitude, praying before engaging in activities, and showing tolerance toward others who practice various religions in the moderate to good range.

A number of questionnaires with 3 options (work, entrepreneurship, and continuing to a higher school level) were given to students of SMK NU Sunan Ampel Poncokusumo Malang. The findings showed that most students chose work and entrepreneurship compared to continuing to a higher school level. Therefore, students need to be equipped with insight into business analysis, so that students are able to manage their business properly. The purpose of this study was to develop an Electronic Learner Worksheet (E-LKPD) of entrepreneurship-based creative product business analysis to form the character of student independence that meets the validity requirements. ADDIE development model was used in this research, namely: analyzing the achievement of core competencies and basic competencies of SMK (Vocational High School), learning resources used, ongoing learning situations, and the level of understanding of Vocational students of business analysis material; designing E-LKPD business analysis and research instruments in the form of material validation sheets and E-LKPD media validation sheets; and analyzing validity data using validation sheets. The results showed the material validity test to assess competence in E-LKPD was 81.25% and the media validity test was 93.75%. The business analysis material fulfills relevant aspects for learner independence and presents information that can measure the level of understanding of students.

The level of human quality development between regions or countries can be measured using the Human Development Index (HDI) value. The higher the value of the HDI, the better the quality of human development in the region. Some variables affect the value of the HDI. This study will test six independent variables using the Geographically Weighted Panel Regression (GWPR) method. This GWPR method combines panel data regression with the Geographically Weighted Regression (GWR) method. This GWPR method combines the dimensions of location and time to determine the effect of the independent variable on the dependent variable. Therefore, the purpose of this study is to see which variables have a significant effect on the value of the HDI in Papua Province. By using panel data regression, the best model that can be formed is the Fixed Effect Model (FEM). However, the FEM model that was formed did not meet the heteroscedasticity assumption test on the residuals, so further modeling was carried out using the GWPR model. GWPR modeling on this data uses a kernel weighting function, whereas previously, data transformation was carried out by the concept of the FEM model. The GWPR model with the best kernel weighting function is fixed exponential. In selecting the best model based on the coefficient of determination , the GWPR model is better than the FEM model. Regarding the significance of model parameters, nine groups of districts/cities based on independent variables significantly affect the HDI. In all districts/cities of Papua Province, the per capita expenditure variable significantly affects the HDI's value.

This study aims to investigate the impact of implementing ethnomathematics on mathematics learning outcomes among fourth-grade students at SD Negeri 02 Bekonang. The research employs a quantitative method with an experimental approach, involving a population of 44 students from classes IV (A) and IV (B). The students were divided into two groups: the experimental class, which applied ethnomathematical concepts through the traditional game engklek, and the control class, which learned without incorporating ethnomathematical concepts. The findings indicate that the experimental class achieved higher post-test scores compared to the control class. The average post-test score for the experimental class was 64.55, while the control class scored 51.82. The t-test analysis yielded a significance value of 0.037 < 0.05, demonstrating a significant influence of ethnomathematics on students' mathematics performance. The ethnomathematical approach, which integrates cultural elements into learning, has proven to be an effective strategy in mathematics education. This approach not only enhances students’ conceptual understanding but also makes learning more engaging and meaningful. In this study, the engklek game was used as a learning medium to introduce the concept of geometric shapes, allowing students to grasp the material more easily through direct experience. Therefore, this approach is recommended for mathematics instruction in elementary schools to foster student engagement and comprehension. This study also encourages teachers to be more creative in developing concrete and contextually relevant teaching methods, ensuring that mathematics is no longer perceived as a daunting subject.

Controversial issues have the potential to stimulate differences or cognitive conflicts in problem-solving, both in terms of approach, argumentation, and the solutions produced. Resolving cognitive conflict can be done not only through conventional logical thinking but also by understanding objects that encompass facts, concepts, principles, and skills, as well as considering external aspects surrounding the problem. This study aims to explore the controversy reasoning problems of university students in solving multiple representation problems. This research is a case study with a qualitative approach. The selected subjects were students who experienced controversy in solving multiple representation problems. The instruments used were tests and interviews. Data analysis was carried out through data reduction, data presentation, and conclusion drawing. There are three levels of controversial reasoning: clarification level, exploration level, and initial level. Among 99 students solving multiple representation problems, the results showed that 19 students (19.19%) were at the initial level, 45 students (45.45%) at the exploration level, and 35 students (35.35%) at the clarification level. Qualitatively, controversial reasoning at the clarification level is the best compared to the exploration and initial levels. The advantage of subjects at the clarification level is that, besides understanding the problem, their algorithmic skills are highly structured. These subjects are also able to provide concise, logical arguments and find the correct solution.
