Reflective abstraction is a process of reflection on previously learned concepts and applied to new situations. This study aims to describe the reflective abstraction of junior high school students in solving mathematical problems in terms of mathematical ability. The source of the data in this study were three male students of class VIII SMPN 20 Surabaya who had different mathematical abilities.The results of this study indicate that students with high mathematical abilities, at the recognition level, are able to remember and identify previous activities related to the problem at hand. At the representation level, students with high mathematical abilities are able to correctly translate information into mathematical models. At the level of structural abstraction, students with high mathematical abilities are able to solve problems correctly, try new ways, and overcome difficulties when solving problems. At the level of structural awareness, students with high mathematical abilities are able to provide arguments from the results of their answers and are able to solve further problems. Students with moderate mathematical abilities, at the introductory level are able to remember previous activities related to the problem at hand. At the representation level, students are able to correctly translate information into mathematical models. At the level of structural abstraction is able to solve the problem correctly. And at the level of structural awareness, students are able to solve new problems. Meanwhile, students with low mathematical abilities are unable to solve problems. Students with low mathematical abilities still have to be guided in the process of solving problems.

One of the important skills to be mastered by students is critical thinking skills. One way to bring up students' critical thinking skills is by confronting them with a problem. The context of the problem that is closest and can be recognized well by students is the context of daily life or is called contextual problem. This research is a qualitative descriptive study. The subjects of this study were three students of 8th grade at SMP Negeri 1 Kedunggalar with each student having high, medium and low mathematical abilities. The method of collecting data in this study is through tests of mathematical abilities, tasks of solving contextual mathematical problems, and interviews. The results showed that junior high school students had high, medium, and low math skills in clarification skills, namely students wrote down the information they knew about questions such as the size of tiles, the size of the library floor, and discounts. Students formulate the main problem, namely finding the cheapest price from a choice of two ceramics, with the concept used, namely the area of a square and a rectangle. In the assessment skills, students assess the information previously mentioned as sufficient to solve the problem and mention the relevance of the information to the completion step, namely the size of the tile area and the area of the library to determine the number of tiles needed. In inference skills, students with high and moderate mathematical abilities show a relationship of ideas related to the steps used, namely finding the number of ceramics, the total price, and the price after the discount. In strategy skills, students evaluate the steps used by reviewing the results of the completion that has been done. Meanwhile students with low mathematical abilities did not describe the relationship from the information known to the problem and could not evaluate the results of the solution.

Mathematics and culture are two things that are closely related to the activities of daily human life. Because Mathematics is a form of culture that is integrated in all people's lives. This means that, in culture we can find various kinds of mathematical concepts called ethnomathematics. Shibori is a technique of manipulating cloth originating from Japan, to create patterns through a dyeing method that has been around since the 8th century. The patterns created in Shibori generally depict an asymmetrical shape. In the Shibori motif there are several mathematical elements, one of which is the Frieze Group pattern. The Frieze Group is a subgroup of a symmetry group that is constructed by translation in one direction. The Frieze pattern has 7 (seven) types of patterns consisting of isometric combinations and can be classified as cyclic or dihedral groups. This study is an ethnographic study, with exploration and documentation of Shibori. The data analysis technique chosen is interview, observation and documentation. The research subjects were Shibori fabric craftsmen in Tulungagung district, East Java. The purpose of this research is to further examine the cultural patterns of Shibori Traditional cloth into Frieze patterns, as a way to understand mathematics through culture. The results of the research conducted have shown that there are mathematical concepts (geometry) in the Shibori motif, namely the Frieze pattern F1, F2, F3, F5, F6, F7. Keywords: Group Frizes; Ethnomathematics; Shibori

The differences in algebraic thinking when solving problems are determined by the characteristics of students. One of the distinguishing characteristics is cognitive style. The study aimed to describe the algebraic thinking profile of students who had reflective cognitive styles in solving mathematics problems. This study used descriptive qualitative research with a case study research design, focusing on 8th grade junior high school students with reflective cognitive style. Data were collected using tests and interviews. This study used three types of tests namely Matching Familiar Figure Test (MFFT) to determine students’ cognitive style, Mathematics Ability Test (AMT) to measure students' mathematical abilities, and Problem-Solving Test (PST) to obtain data related to students’ algebraic thinking profile in solving mathematics problems. Data were analyzed in three stages covering data reduction, data presentation, and conclusion drawing. The results showed that the algebraic thinking of students with reflective cognitive style in solving problems met the three aspects of algebraic thinking indicators namely performing activities to generalize the pattern and determine the next term of the given pattern, representing and comparing data in tabular form, and understanding the meaning of variables and use variables in the form of letters or symbols as a representation of something unknown value in algebraic form. Students with a reflective cognitive style in solving problems could understand the problems given well, be careful and thorough in writing the steps of completion, and straightforward and coherent in answering questions so that the answers given tend to be correct. Thus, the results of this study are expected to be one of the references for teachers or other researchers in developing mathematics learning by considering the cognitive style the students, especially reflective cognitive style.

This study aims to describe students' analogical thinking abilities in solving mathematical problems. The subjects of this study were one fieldindependent cognitive-style student and one junior high school student from class VII.. The instruments used are analogical thinking ability test, and interview . The results of this study show that students in the coding stage did not write down the information in the questions on their answer sheets, however, they were able to explain during interviews. In the conclusion stage, students use methods that they consider easy and have used these methods before. In the mapping stage, students can identify the relationship between the source problem and the target problem during the interview, which can be seen from the similarity of the information known and asked. In the application stage students get conclusions from the solution to the source problem and target problem.
