The importance of multiple mathematical representations for students in learning is that one of them can help students learn and build a concept to overcome a problem in solving story problems. The purpose of this study was to determine the profile of multi-representation abilities in solving story problems for students with auditory learning styles. This type of research is descriptive qualitative research. The subjects in this study were four students with auditory learning styles from class XI IPA 1 SMA Negeri 1 Bangsri. Data collection methods used are learning style questionnaire tests, mathematical representation tests, and interviews. The results of this study indicate that students with auditory learning styles based on mathematical representation abilities are able to solve all the questions given. In solving story problems, the subject always writes down what is known and asked first, then answers the problem. Subjects use visual representations in the form of illustrations and tables to make it easier to answer. Next, the subject writes down what is known and asked using verbal and symbolic representations according to what is written on the problem. Auditory subjects solve these problems by involving symbolic representations (mathematical expressions) by substituting them into mathematical formulas. To explain the important part of the problem and write a conclusion at the end of the subject's answer, use a verbal representation in the form of words, sentences, or written text.

This study aims to determine the representational abilities of class VIII junior high school students in solving word problems on opportunity material in terms of student learning styles. This research is a qualitative descriptive study. This research was conducted in class VIII B and VIII E of SMP Miftahul Ulum Boarding School Jogoloyo Demak which were selected based on the results of a questionnaire test. The subjects of this study were selected based on a learning style questionnaire of 60 grade VIII students, 6 students were selected consisting of 2 subjects with a visual learning style, 2 subjects with an auditory learning style, and 2 subjects with a kinesthetic learning style. . The instruments used in this study were a learning style questionnaire test to determine research subjects, math word problems to bring out students' representation abilities, and interview guidelines. The validity of the data uses technical triangulation, namely checking data that has been obtained from the same source using different techniques. The results of the research based on tests and interviews obtained 1) subjects with a visual learning style gave rise to visual representation indicators, and representations of mathematical equations or expressions. 2) subjects with learning styles bring up indicators of visual representation, and representation of equations or mathematical expressions. 3) subjects with kinesthetic learning styles only bring up visual representation indicators.

This study uses the systematic literature review (SLR) method to identify knowledge trends in beliefs about the nature of mathematics, learning mathematics and identify new development opportunities for further research. The Scopus database was used, and 41 documents were found as the primary source for further analysis. The results show that mathematical beliefs have become a current research trend. The number of publications increased significantly starting in 1989, accompanied by many citations. Based on these primary documents, it is known that the development of mathematical beliefs research topics. The foundation of this topic begins with studying the topic of knowledge, activities, and learning mathematics. Then it is developed into other, more varied studies, including teacher’s beliefs transition; mathematical beliefs comparison; mathematics teacher’s belief, teaching, and learning; mathematical beliefs and problem-solving; inquiry-based learning (IBL); affective factors; technology utilization; common misconceptions; and development of mathematics teacher’s beliefs instrument. This research investigates the core of scientific work to provide information to researchers and institutions as material for consideration of research to be carried out.

This research is motivated by low numeracy literacy skills which are a crucial problem in educational development, especially at SMA Negeri 2 Semarang. This research aims to find out whether the Problem Based Learning (PBL) model is effective in improving high school students' mathematical numeracy literacy skills. This research uses the classroom action research (PTK) method by applying the Kurt Lewin model which includes planning, implementation, observation and reflection stages. The subjects of this research were 36 class X.8 students. Data was collected through a numeracy literacy skills test at the pre-cycle, cycle I and cycle II stages. The results of the research show that the actions taken succeeded in achieving success indicators with more than 75% of students achieving completeness, namely 79.4% or 80%. The implications of this research show that the PBL model can have a positive impact on student learning outcomes in improving mathematical numeracy literacy skills in high school.
