Using schemes of Euclid's geometrical concepts in long-term memory to understand hyperbolic geometry and elliptic geometry concepts with assimilation and accommodation allows for cognitive conflict. This study aims to reduce the occurrence of cognitive conflict by understanding the mathematical content of the three of Euclidean geometries, hyperbolic and elliptic. The research was conduct used descriptive exploratory. The results indicate that Euclid's geometry representation is still used in representing hyperbolic and elliptic geometry so that cognitive conflict occurs. Cognitive conflicts that occur are related to the position of two lines, parallels, two triangles with the same that correspond angles, intersects one of two parallel lines, the number of angles in a triangle, and Sacherri's valid hypothesis. The efforts that can be made to reduce the occurrence of cognitive conflict are to change existing schemes or create new schemes so that the information obtained can be combined into existing schemes in a deductive axiomatic approach to material content through the accommodation process

Geometry teaches us not only about how to give appreciation for something, but also how to find connections that occur between geometry material and other lecture material. In addition, geometry also trains communication through exploration, discussion, conjecture and investigation. The problems that exist in basic geometry skills in a row are problems related to logic skills, drawing skills, visual skills, verbal skills, and applied skills. Based on geometric learning using analytical presentation, the problem of using axiomatic deductive is at the top, then the problem of perception. Misconceptions about visual processes and activities, and finally problems with the use of procedures, concepts, and principles

This research is a qualitative descriptive study that aims to describe the mathematical literacy of high school students with a systematic and intuitive cognitive style in solving PISA model questions. The cognitive style test, cognitive style inventory, and mathematics ability test were used to select research subjects. One student with a systematic cognitive style and one with an intuitive cognitive style were selected with equivalent mathematical abilities and the same gender. The results of the mathematical literacy test and test-based interviews were used to collect data on students' mathematical literacy. Time triangulation was used to test the credibility of the findings obtained. Data analysis techniques include data reduction, presentation, and drawing conclusions. The research results show that in formulating problems, systematic students identify the information obtained from the two questions in more detail and are more careful in understanding the questions, while intuitive students identify the necessary information to solve the problem in general. In applying problems, systematic students design and use strategies to find solutions, identifying known information from the problem first, while intuitive students create and use strategies to find solutions and solve problems using the concept of comparison. For the interpreting aspect, the two students reinterpreted the mathematical results they obtained into contextual problems, stated the truth of the answers they obtained, and provided arguments to support their answers.

The purpose of this research is to describe the profile of students' creative thinking in solving math problems in terms of gender. This type of research is a qualitative descriptive research. The subjects in this study were one male student and one female student. The two subjects had high and equal mathematical abilities. The research results obtained in this study were (1) The creative thinking profile of male students in solving math problems, namely at the (read and explore) stage of understanding the problem, the male subject found important elements in the problem including elements that were known and asked . After knowing what was asked in the question, the subject also knew and explained verbally every element of the information that was known and what was asked had a relationship. At the (select a strategy) stage of choosing a solution strategy, the male subject knows the various ideas used in solving TPM and can explain well the reasons for using these ideas so that this fulfills the flexibility indicator. At the (solve the problem) stage of carrying out problem solving, the male subject put forward various strategies used in solving the problem, namely by combining the rules of subtraction with multiplication of integers and using a number line. After knowing the ideas and strategies used, the subject implements these ideas and strategies in solving TPM problems so that this shows that the subject meets the indicators of fluency and novelty. At the (review and extend) stage of checking the answers again, the male subject verbally said that the solution to the problem was correct by checking the answers. The strategy used in checking answers with the rules of integer arithmetic operations is to see the results of changes in the temperature of each city and to make a number line so that in this case it meets the indicators of flexibility (flexibility) and fluency (fluency).

The descriptive study analyzed the skills of vocational school students with low, medium, and high levels of mathematical anxiety in terms of their problem-solving abilities. It used a qualitative approach to examine the various mathematical content strands and scientific contexts of the learners. Its findings were based on the notion of the problem-solving stage by Polya, Newman, as well as Krulik and Rudnik. The data collected during the study was gathered through a written test, which involved asking the participants to complete a questionnaire about their mathematical anxiety levels before they were asked to solve numeracy problems. The results of the study revealed that students with high levels of anxiety were more prone to experiencing problems with problem-solving. The findings of this study are valuable to mathematics educators and researchers. It is also expected to contribute to the development of effective problem-solving strategies for students.

Mathematical literacy and ethnomatematics are two main ideasÂ to determine the role ofÂ mathematics in everyday life. Mathematical literacy is an idea that focuses on mathematical and social requirements that can reflect a person's competence in mathematics, while ethno-mathematics emphasizes the competence of people developed in different cultural groups in everyday life. This research focuses on the Jonegoroan batik culture (batik typical of Bojonegoro Regency) because no previous researchers have studied it, especially about ethno-mathematics and mathematical literacy. The purpose of this study was to describe the ethnomatematic form of Jonegoroan batik in terms of mathematical literacy aspects, namely aspects of the content, context, and mathematical processes. This type of research is qualitative research with an ethnographic approach. Data collection was carried out by means of participant observation and interviews. The instruments used were observation sheets, interview guidelines, and research note sheets. The data analysis technique used triangulation. The results of this study indicate that based on ethnomatematic studies on Jonegoroan batik, several mathematical concepts can be found, namely the concept of geometric transformation,Â two-dimentional figure, and graphs of trigonometric functions. Based on these studies, the activities carried out by Jonegoroan batik craftsmen fulfill the aspects of mathematical literacy. Thus, Jonegoroan batik can be used as a medium for learning mathematics.
