Mathematical representation is how a person communicates the mathematical ideas in question to others. This ability has an important role in learning mathematics, especially as a foundation to align problem solving. This study aims to describe the mathematical representational ability of junior high school students in solving open-ended problems. The study subjects were students of grade XI junior high school. This research is qualitative descriptive research. Taking subjects using purposive sampling, which is based on their thinking style. Data collection uses tests, questionnaires, and interviews. The results showed that the ability of mathematical representations of: (1) groups of students of concrete sequential thinking styles able to create and communicate mathematical ideas in the form of images, have not been able to make mathematical models perfectly and are sufficiently able to use written words or text; (2) groups of students of abstract sequential thinking styles are less able to create and communicate mathematical ideas in the form of drawings but able to create mathematical models of ideas or ideas and are sufficiently able to use written words or text; (3) groups of students of abstract random thinking styles are less able to create and communicate mathematical ideas in the form of drawings and create mathematical models of ideas or ideas, but are sufficiently able to use written words or text; (4) Groups of students of concrete random thinking styles are quite capable of creating and communicating mathematical ideas in the form of drawings, unable to create mathematical models of ideas or ideas, less able to use written words or text

The study aims to find out pseudo-thinking in solving mathematical problems. The methods used in this study are qualitative descriptive. The research subject is junior high school students using the purposive sampling technique, the students are grouped into three ranks i.e. low, medium and high rankings which each ranked 3 students as respondents. The total number of respondents was 9 students. Data collection techniques using tests, interviews, and documentation. From the results of the study gained that: 1) students who are ranked low in solving mathematical problems are experiencing pseudo-analytic or pseudo-false, 2) students who are in the moderate level also experience pseudo-analytic or pseudo-incorrect, 3) students who are in high ranking experience pseudo-analytic and pseudo-4) students who experience pseudo-thinking choose procedures using their own reasoning and convince it as a correct understanding , so there is no attempt to re-examine what he has done

This research aims to find out the description of Mathematic Combinatory Thiking Ability of the Students. This is a descriptive qualitative research. The subject of the research was the students of Grade XI.MIA-5 SMAN 5 Purwokerto. The technique of the data collection in this research was by test, interview and documentation. The result of the students’ mathematic combinatory thinking ability was grouped in 3, namely the high, middle, and low. Each group was taken 3 as the respodents. The result of the research showed that mathematic combinatory thinking ability of the high could understand the problem faced and started to find the possibility of answering the correct answer, find all possible answers correctly, and able to solve more than one combinatory problem in one single mechanism. The students’ mathematic combinatory thinking ability of the middle could understand the problem faced and started to find the possibility of answering the correct answer, find all possible answers correctly. Then, the students’ mathematic combinatory thinking ability of the low could only understand the problem faced and started to find the possibility of answering the correct answer.

Mathematical literacy is an individual's ability to use mathematical knowledge to solve everyday problems. This study aims to describe the mathematical literacy ability of junior high school students viewed from intrapersonal intelligence. This research is a qualitative descriptive study with the subject of SMP Negeri 2 Jatinegara students. The purposive sampling technique was employed in the sampling process. Intrapersonal intelligence questionnaires, mathematical literacy tests, and interviews were used to collect data. The questionnaire was used to classify high, medium, and low intrapersonal intelligence students. Tests and interviews were used to describe mathematical literacy skills. The results showed that students with high intrapersonal intelligence had mastered 4 indicators of mathematical literacy: identifying aspects of the problem, turning the problem into an appropriate mathematical image, applying mathematical models to find solutions to problems, and interpreting mathematical solutions/results. Students with medium intrapersonal intelligence had mastered 3 indicators of mathematical literacy: identifying aspects of the problem, turning the problem into an appropriate mathematical image, and interpreting the solution/mathematical result. Students with low intrapersonal intelligence had mastered one indicator of mathematical literacy ability: identifying aspects of the problem

Design thinking can help students think outside the box and develop creativity. This study aims to describe students' design thinking skills based on the level of creativity in class X Merdeka 8 SMA Negeri 1 Purwokerto. The subjects involved in this study were 36 students. The type of research used is qualitative descriptive. The data collection techniques used are written tests, interviews, and documentation. Based on the results of the creativity level test, students are grouped into five levels, namely very creative, creative, quite creative, less creative and not creative. Each level of creativity is chosen by one student using purposive sampling techniques. The results of this study show that students with a very creative and creative level are able to meet the five indicators of design thinking, namely emphatize, define, ideate, prototype, and test. Students with a creative level are able to meet 4 indicators, namely emphatize, define, ideate and prototype. While students with non-creative levels are only able to meet the indicators of emphatize, define, and ideate
