Only 28% of students in Indonesia are capable of interpreting problems into mathematical models, due to their lack of understanding of basic mathematical concepts. The purpose of stimulating and guided training is to provide students with a good understanding of problem solving in mathematics. Based on this concept, the purpose of developing the Basic Mathematical Solution Application (SOLMATDAS) is to provide understanding to students with guided training using android as the medium. Media development follows the 4D methodology (Define, Design, Develop, Disseminate), with media and ICT validation by each expert and media effectiveness by learning participants. from the results of the validation test, the percentage of learning expert validation was 90% and ICT expert validation was 90.2%, so the media can be categorized as very valid and can be used as a learning media, whereas after dissemination and testing the effectiveness of the media in obtaining pretest and posttest scores it was carried out by teacher to students in one class. The results of processing the pre-test and post-test statistics obtained a significance value of 0.038, because the significance is less than 0.05 which means there are differences in learning outcomes using SOLMAT and direct learning. From these results it can be concluded that the use of the SOLMAT application can assist in advanced mathematics learning activities which requires an understanding of basic mathematical concepts.

Set is one of the main materials contained in the mathematics subject for 7th-grade junior high school in odd semesters. In the set material, there's no formula used, but there are various kinds of notations, symbols, and also diagrams. Basically, some or even most students still face various difficulties in understanding and working on problems in set operations. This study aims to determine the types of errors and the percentage of errors in 7th-grade junior high school's responses to set material test questions using Newman's error analysis procedure. In this study, we used a qualitative descriptive method, while the data processing technique was done by analyzing student answers based on questions that were test instruments. The research subjects were taken from students in the VII-E class at SMP IT Fithrah Insani, which included as many as 22 students. Then the subjects were analyzed, and based on the results of the research, it turned out that there were still errors in solving set questions. The most frequent error made by students is an encoding error of 40.91%. In this error, the student did not write a complete final answer, or even the conclusion of the solution, so that he did not answer the question posed by the problem.

Ethnomathematics is a realistic approach to learning mathematics that relates mathematical concepts to culture. By learning mathematics relevant to the student environment's culture, students will more easily understand mathematical concepts. This study aimed to examine theethnomathematical exploration of the Kebyok Anting-Anting dance floor pattern for learning the concept of geometry. This research is qualitative research using the ethnographic method. The instruments used are interviews, observation, and documentation. Data obtained through interviews and observations were analyzed using the analytical method described by Miles & Huberman, there are data reduction, data data display, and conclusion drawing/verification. The results showed that the ethnomathematical investigation in the Kebyok Anting-Anting dance floor patterns for learning the concept of geometry were horizontal lines, vertical lines, squares, rectangles, isosceles trapezoids, isosceles triangles, and parallelograms. It is hoped that various local cultures can be used to introduce other mathematical concepts.

To study at school, students must have soft skills such as self-regulated learning, namely the ability of students to manage their own learning. The significance of students' self-regulated learning is what inspired this study. This study sought to ascertain the rise in students' self-regulated learning when learning mathematics using a realistic mathematics education model, as well as the students' reactions to learning mathematics using a realistic mathematics education model. This kind of study uses questionnaire analysis to do descriptive research. A self- regulated learning questionnaire and a questionnaire for students' responses made up the tool used to assess the self-regulated learning abilities that had been put to the test. Data were collected for this study to examine the rise in realistic mathematics education students' ability to learn mathematics independently, as well as the students' attitudes toward learning mathematics through mathematics education, which were assessed using a Likert attitude scale. The self-regulated learning scale is made up of four parts: the students' evaluations of how well they (1) use and locate pertinent learning resources in mathematics, (2) select and determine their learning strategies in mathematics, (3) assess and evaluate their learning outcomes in mathematics, and (4) have a positive view of themselves as mathematicians. By utilizing realistic mathematics education, the findings of this study about self-regulated learning in mathematics can be viewed as a whole. Based on the results of data analysis it is known that students' responses to realistic mathematics education models are positive which are adapted to real-life contexts or everyday life which will arouse students' self-regulated learning in solving problems because they are related to real life. This demonstrates that 98.18% of students respond positively.

A total of 31 grade 8th junior high school students were selected by purposive sampling technique as respondents in this case study research. The case study approach is considered in accordance with the objectives of this study, namely obtaining in-depth knowledge of student problems, knowing the causes of these problems, and efforts that can be made to help overcome them. Methods of collecting data using written tests, interviews, and documentation. Data analysis techniques include data reduction, data presentation, and drawing conclusions. The results showed that there was a misunderstanding of students' concepts about the concept of factorization in algebraic forms so that they experienced difficulties in "algebraic manipulation". One of the causes of these difficulties is the lack of students' understanding of the equals sign as a sign of equality. The principle of mathematical equivalence serves as the main link between arithmetic and algebra. The operation transformation and the meaning of the equals sign in arithmetic as equality can underlie "algebraic manipulation".

Education is one of the learning processes to improve a person's skills and behavior. Mathematical understanding is the ability to understand concepts, the ability to distinguish concepts, and the ability to calculate complex situations or problems. Adversity quotient is the response of a person or individual when faced with problems or difficulties in his life. The main problem in one of the schools in Sumedang is the students' thinking about mathematics lessons, where this lesson is less preferred than other lessons. The method used by this study is descriptive quantitative. This research was carried out in the even semester of 2021/2022, in one of the regional schools in Sumedang, class VII totaling 15 students. The data generated from this research is in the form of an instrument, which consists of indicators of students’ mathematical understanding and there are 3 questions on indicators of mathematical understanding. The methods of data collection in this study are as follows: 1) test descriptions of questions or instruments to determine students’ understanding abilities, 2) direct interviews with students. Research results from student answers according to students’ understanding abilities in terms of AQ, as follows: 1) The results of student responses in terms of Adversity Quotient as many as 3 Climber type students (high) the average percentage of students’ understanding ability is 80%, 2) The results of students responses in terms od Adversity Quotient as many as 9 Climber students (enough) the average percentage of students’ understanding ability is 5,77%, 3) The results of students responses in terms of the Adversity Quotient as many as 3 students Cumper type (medium)the average percentage of students’ understanding ability is 15,1%.
