At the end of the sixties of last century, the development of Realistic Mathematics Education (RME) started in the Netherlands. At the beginning of this century, the Indonesian adaptation of RME, Pendidikan Matematika Realistik Indonesia (PMRI), started. The implementation of RME / PMRI has proven to be challenging. In this research, a qualitative case study was used to investigate teachers’ perceptions and experiences in implementing RME/PMRI in their classes. Semi-structured interviews were conducted with several Dutch and Indonesian teachers who have joined the RME/PMRI training. We found similarities and differences between the two groups of teachers. Both groups of teachers understand the use of context as a starting point for students to construct mathematical understanding. The Dutch teachers considered the construction of interesting mathematical problems and the use of the guided-reinvention principle as the difficulties but motivated them to do more practice. Indonesian teachers mentioned that for them, the integration of mathematics with other subject areas for integrated thematic learning in the 2013 curriculum was their constraint but it was also a challenge for them to be more creative. These perspectives can become a reference for the development of a localized implementation of learning trajectory in classroom practices.

Over the last few decades, many studies have placed attention on math anxiety in students, but math teachers can also experience anxiety that requires the attention. Math teachers can experience the anxiety in the form of math anxiety and math teaching anxiety, which can affect the learning process of mathematics. The purpose of this study is to identify the factors that cause math anxiety and math teaching anxiety in teachers. The method used in this research is Systematic Literature Review (SLR) with a survey-based descriptive approach through analysis the articles that fulfilled the inclution criteria, namely (1) published during the last ten years (2013-2022), (2) written in Indonesian or English, (3) indexed by Scopus or Sinta, which are browsed on the Google Scholar, ERIC, and Garuda database using the keywords “teachers’ math anxiety" and “teacher’s math teaching anxiety”. The results showed that mathematics teachers who experience mathematics anxiety in the form of feelings of worry and discomfort when thinking or doing something related to mathematics, this is caused by a low level of mathematics knowledge and self-confidence, while mathematics teaching anxiety causes worry and feeling uncomfortable when going to or teaching mathematics, this is caused by several factors such as experiencing mathematics anxiety, low mastery of learning technology, low levels of self-confidence, and unsupportive learning infrastructure.

Semiotika memiliki peran untuk menunjukkan pentingnya makna tanda dalam pembelajaran matematika. Lingkaran merupakan bagian dari matematika yang pemahaman konseptualnya sangat bergantung pada interpretasi tanda, terutama dalam proses pemecahan masalah yang melibatkan proses kognitif. Tulisan ini bertujuan untuk mendeskripsikan proses kognitif siswa dalam pemecahan masalah, melalui hubungan antar komponen triadik (semiosis) Peirce, yaitu representamen (R) - object (O) - interpretant (I). Penelitian ini merupakan penelitian deskriptif kualitatif melalui tahapan pemberian pertanyaan (masalah), penentuan subjek, wawancara, analisis data, dan penarikan kesimpulan. Subjek dipilih berdasarkan prestasi belajar. Hasil penelitian ini menemukan tiga tahapan dalam proses semiotik: 1) representamen (membuat tanda), 2) objek (mengidentifikasi objek, 3) interpretan (menginterpretasi tanda). Oleh karena itu, penelitian ini penting untuk membantu meningkatkan kualitas pendidikan di Indonesia dengan memberikan informasi tentang bagaimana siswa dapat memperoleh pemahaman yang lebih baik tentang geometri.

Mathematics class can cause many problems if students do not organize diversity and habits correctly. Using a sociograph to form a mathematics study group is one way to organize assortment in the mathematics class. Sociograph is a friendship pathway that appears in a math class. In this sense, this study aims to determine the impact of forming study groups based on friendship in a mathematics class on problem-solving abilities. A quasi-experimental research design with 30 students was used. A friendship questionnaire and a problem-solving test were used as instruments. In addition, an independent t-test was used to analyze the data. The study results indicate that study groups formed through friendship pathways (sociograph) have a more significant effect than those formed through other means. As a result, the formation of heterogeneous groups based on friendship can be used as an alternative to the formation of study groups.
