Students' mathematical communication skills are still not optimal, this can be seen when students have difficulty in expressing their mathematical ideas in the form of writing or pictures. Students can understand the meaning of the problem given, but have difficulty communicating it again in the form of a mathematical model. This study aims to determine the mathematical communication skills of class VIII students in solving mathematical problems based on visual and auditory learning styles. The subjects of this study were eighth grade students of SMP Negeri 25 Semarang, each with one student with a visual learning style and one student with an auditory learning style. Data collection techniques used questionnaires to classify students based on learning styles, written tests, and interviews to determine students' mathematical communication skills. The validity test of the data used is triangulation technique by comparing the results of the written test and the results of the interview. The results of the study concluded that both students with a visual learning style and students with an auditory learning style have met the indicators of expressing everyday events into language or mathematical symbols and can explain ideas, situations, and mathematical relationships with real objects, pictures, graphs, and algebra . However, students with an auditory learning style have a higher level of accuracy than students with a visual learning style in writing mathematical symbols in the process of solving problems in solid-sided geometric material.

Mathematics learning experiences a paradigm shift in its development. It is followed by various mathematics learning approaches including ethnomathematical approach. Ethnomathematical approach integrates the characters and cultural literacy in mathematics learning. Therefore, it is able to instil the mathematics concepts through the cultural practice which is implemented in the learning process. One of it is conducted through the exploration of regency local wisdom that has a role in developing ethnomathematical. This study implements the concepts of regency local wisdom which is able to be adopted in ethnomathematical learning. This study is qualitative research in which the researcher observes the local wisdom of Bojonegoro regency, East Java, Indonesia. The data obtained is related with the rational stories behind the culture. Based on observation results, Bojonegoro local wisdom such as Oklik, Tengul dance, and Khayangan Api story can be integrated in mathematics learning. Understanding the local wisdom stories can potentially bring out the values of it and connect culture with mathematics. Those stories can be implemented in mathematics learning by providing HOTS (higher order thinking skill) questions which are relevant to the learning materials.

The purpose of this study is to describe a research-based learning model to foster students' creative thinking skills and independence. A Systematic Literature Review (SLR) is used as a method of analyzing of various articles and literature obtained by searching for data sources. The results of the analysis from these various sources are translated detailed review. Creative thinking skills in mathematics are needed to create (formulate), complete, and complete a model or problem-solving plan. The ability to think creatively needs to be developed as the main provision to face life. The importance of independent learning in schema thinking helps build components of a schema that are connected in a network of creative thinking abilities. To develop these two goals, namely the ability to think creatively mathematically and independent learning, it is necessary to pursue a learning activity that further explores the ability of students to solve problems creatively, and in the process helps to develop independent learning. The learning model that leads to these benefits is Research-Based Learning.
