This study aims to describe the critical thinking profile of SMAN 5 Model Palu grade XI students in solving trigonometric identity proof problems regarding gender differences. The subjects in this study were male students or S1 and female students or S2 of grade XI Mipa 4 SMAN 5 Model Palu who have high mathematical abilities. Data were collected through tests and interviews. The results of this study indicate that S1 and S2 in solving trigonometric identity proofs have the correct answers and are accompanied by supporting reasons. However, there are some differences in thinking activities between the two, namely S1 who is a male student with high ability has a shorter answer than the solution of S2 who is a female student with high ability, S1 uses a logical way of thinking compared to S2 who tends to be proficient with his verbal abilities. This shows that S1 and S2 even though they have equal mathematical abilities, there are some differences between the two in solving trigonometric identity proofs whose data are obtained from written assignment answers and interview results.

This research was motivated by the phenomenon of implementing the minimum competency assessment (AKM) in class V at SD Negeri 01 in Karanganyar Regency. The researcher discussed in depth the numeracy literacy skills and challenges faced by grade 5 students in working on minimum competency assessment (AKM) mathematics questions at SD Negeri 01 in Karanganyar Regency as well as the opportunities gained from the results of the minimum competency assessment test (AKM) at SD Negeri 01 in Karanganyar Regency. The aim of this research is to 1) describe numeracy literacy and the challenges faced in working on minimum competency assessment (AKM) questions in mathematics for class V students at SD Negeri 01 in Karanganyar Regency, 2) describe the opportunities obtained from the results of the minimum competency assessment test (AKM) mathematics for class V students at SD Negeri 01 in Karanganyar Regency. This research method uses qualitative research using a case study approach. MThe results of this research show: 1) numeracy literacy skills are still low. This is proven by the average score of the Minimum Competency Assessment (AKM) test results, which is 28.24 out of a total of 17 students. The challenges faced are that students are using laptops for the first time in the test, students still cannot understand the questions in the AKM test, students are still difficulty in determining the formula used to solve the problem, and the material that has been taught by the teacher is still not well understood, 2) the opportunity for the Basic Competency Assessment (AKM) test can be used as an evaluation for teachers in making learning improvements for students to improve their abilities numeracy literacy. This implies improving the learning process, increasing evaluation and measurement as well as individual intervention and support for students.

This research examines students' mistakes in solving mathematics story problems, especially algebraic arithmetic operation story problems, based on Kastolan theory and examines what factors cause students to make these mistakes. The type of research used in this research is descriptive qualitative. The place where the research was carried out was SMP Negeri 6 Palu. The subjects taken in this research were class VII students at SMP Negeri 6 Palu, consisting of 1 student with several considerations obtained as students with low MH abilities. Before analyzing the data obtained, it is validated first using member check. The data analysis techniques used in this research are data reduction, data presentation and drawing conclusions. The results of this research show that subject MH made 3 types of errors based on Kastolan's theory, namely: Conceptual Errors in the form of the subject not being able to apply the formula, classifying the form of variables in solving the problem when using the formula that has been obtained, the subject not writing completely the information known in the problem and errors in substituting known information into the question. Procedural errors in the form of irregularity in the solution steps used by the subject, there are several steps that are skipped so that the solution becomes wrong until the final stage of solving the problem. Technical error in the form of Subject MH making an error in calculating the value in the arithmetic operation shown in the subject only dividing by 2 each solution to get the result of the question in the problem because the subject did not understand the formula to be used and was not correct in substituting the value in the problem into problem solving. The factors that cause errors made by students are divided into two, namely internal and external factors. Internal factors include low basic knowledge regarding the form of arithmetic operations, solving steps for story questions and low knowledge of algebraic material. Lack of practice working on questions in the form of story problems and students' lack of accuracy in solving story problems. The external factor is that students are in a hurry when completing story problems because they want to finish them immediately and go to do other activities with their friends.

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.
