In preparing a Lesson Plan, a mathematics teacher should pay attention to pedagogical principles, including general and mathematical pedagogy. Teacher knowledge related to these two pedagogies is called Pedagogical Content Knowledge (PCK). This study aims to analyze the PCK of a mathematics teacher at a junior high school in Kebumen when preparing lesson plans and carrying out learning activities on Ratio Topics. This study used a qualitative research method with a case study design. The teacher’s PCK analyzed in this study was divided into two parts: general pedagogical knowledge and mathematical pedagogical knowledge. The results showed teachers' general pedagogical knowledge when learning was more complete than when compiling lesson plans. Likewise, in mathematical pedagogy, the teacher's mathematical pedagogy knowledge when carrying out education is better than when compiling lesson plans. This also indicates a mismatch between the lesson plans compiled by the teacher and the learning activities he carried out. Therefore, in compiling lesson plans, teachers are advised to pour all pedagogical content knowledge that they have so that the lesson plans are by the learning activities carried out by the teacher so that the entire learning process can be carried out more optimally.

Textbooks are one of the learning media that need to be evaluated objectively because textbooks are a form of curriculum implementation that teachers usually use in the classroom. Many developed countries pay more attention to this study such as Japan, America, Holland, so textbook studies have been widely recognized as a field of scientific research. According to the Theory of Didactical Situations, the content of the material being taught must allow students to think. to make an objective analysis of the book, Researchers used Praxeology in this study. Praxeology, initiated by Chevallard, helps researchers see the reasons behind human action in textbooks and math. Based on the praxiological analysis, the result is that the design of the textbook does not provide techniques that facilitate students to acquire theory independently. In addition, the situations and actions students should go through need to be properly accommodated. This guides researchers to create alternative designs to provide meaningful learning experiences on broad flat material referring to the Theory of Didactic Situations.

Perubahan pelaksanaan UN (Ujian Nasional) menjadi AKM (Asesmen Kompetensi Minimum) didasarkan pada hasil evaluasi capaian PISA siswa di Indonesia yang masih rendah. Rendahnya capaian siswa pada asesmen internasional tersebut berdasarkan berbagai penelitian di Indonesia salah satunya disebabkan oleh faktor guru atau calon guru. Guru merupakan ujung tombak yang paling mempengaruhi keberhasilan siswa dalam belajar. Oleh sebab itu, pada penelitian dilakukan analisis capaian mahasiswa dalam menyelesaikan masalah numerasi berdasarkan level numerasi dan faktor yang mempengaruhi capaian tersebut. Penelitian ini menggunakan metode penelitian deskriptif kuantitatif yang ditujukan untuk mendeskripsikan data-data kuantitatif terkait kemampuan numerasi mahasiswa dalam menyelesaikan masalah matematika berdasarkan level numerasi (knowing, applying, reasoning). Ada 10 masalah numerasi berbasis online yang diberikan, yaitu 4 soal pada level knowing, 4 soal pada level applying, dan 2 soal pada level reasoning dengan subjek penelitian sebanyak 29 mahasiswa. Berdasarkan hasil analisis penelitian diperoleh bahwa 74% mahasiswa mampu menyelesaikan masalah level knowing atau capaiannya kategori tinggi, 49% mampu menyelesaikan masalah level applying atau capaiannya kategori sedang, dan 30% mahasiswa mampu menyelesaikan masalah level reasoning atau capaiannya kategori rendah. Faktor yang paling mempengaruhi kurangnya capaian mahasiswa pada level reasoning adalah belum terbiasanya mahasiswa memberikan alasan dalam menyelesaikan masalah matematika mulai dari tingkat sekolah dasar hingga menengah atas/sederajat.

Pemahaman konteks matematika merupakan kemampuan yang penting dikuasai siswa dalam rangka memaknai matematika. Namun data lapangan menunjukan pemahaman konteks yang dimiliki siswa masih tergolong rendah. Tujuan dari penelitian ini adalah menganalisis pemanfaatan konteks yang dilakukan oleh guru dalam pembelajaran matematika serta mengetahui faktor – faktor apa saja yang menjadi penghambat sekaligus pendukung pemanfaatan konteks dalam pembelajaran matematika. Penelitian ini menggunakan pendekatan kualitatif dengan metode penelitian fenomenologi. Partisipan penelitian ini adalah guru matematika sekolah SLTA sebanyak 8 orang yang sudah mengajar setidaknya 2 tahun. Hasil penelitian ini menunjukan bahwa pemanfaatan konteks yang dilakukan oleh guru dalam pembelajaran matematika masih mengalami keterbatasan baik dari segi metode penyampaian maupun dari segi jenis konteks yang digunakan. Adapun faktor – faktor yang menjadi penghambat sekaligus pendukung pemanfaatan konteks dalam pembelajaran matematika yaitu kemampuan guru, jenis dan tingkat kesulitan materi, kemampuan dan motivasi siswa, serta ketersediaan media. Understanding the context of mathematics is an important ability for students to master in order to interpret mathematics. However, field data shows that students' understanding of the context is still relatively low. The purpose of this study is to analyze the use of context by teachers in learning mathematics and to find out what factors inhibit and support the use of context in learning mathematics. This study uses a qualitative approach with phenomenological research methods. The participants of this study were 8 high school mathematics teachers who had taught for at least 2 years. The results of this study indicate that the use of context by teachers in learning mathematics is still experiencing limitations both in terms of the method of delivery and in terms of the type of context used. The factors that inhibit and support the use of context in learning mathematics are the ability of the teacher, the type and level of difficulty of the material, the ability and motivation of students, and the availability of media.

Islamic contexts help stimulate students' mathematical abilities and develop their religious thinking. Therefore, this research aims to describe students' thinking process in solving mathematical literacy problems adapted from PISA questions using Islamic contexts. This research is qualitative-descriptive in nature with the purposive sampling technique used to select the three best teams competing on the National Mathematics Olympiad organized by the Mathematics Education Study Program of UIN Syarif Hidayatullah Jakarta in 2018. Each school level (Islamic elementary school (MI), Islamic junior high school (MTs), and Islamic senior high school (MA)) was represented by a team of 3 students. Data were collected through tests of mathematical literacy in Islamic contexts that matched PISA contexts and through interviews. Then, the data collected were analysed using triangulation techniques. The results showed that the students' thinking process in solving mathematical literacy problems in Islamic contexts was in accordance with Bayer’s thinking process theory. In general, the students already engaged in a thought process starting from information processing to decision-making. In fact, some MTs students had reached the thinking level of analysing relationships, synthesising problems or arguments, and conducting evaluations using several criteria suitable for the MA level. So it can be concluded that he Islamic contexts used in mathematical literacy questions tend to draw students' attention to the problems and help them solve those problems.

The study aims to analyze the ability of mathematical connections in a sequence and series of materials conducted when learning offline after previously applied online learning. This type of research is qualitative with data collection techniques, namely mathematical connection ability tests and interviews. The subjects of the study consisted of 4 class XI SMK students in Bandung Regency who had previously studied sequence and series online. Analysis carried out on mathematical connection ability seen from indicators of connection ability is understanding the equivalent representation of the same concept or procedure, looking for connections with procedures to other procedures in equivalent representations, using mathematics in everyday life and using connections between mathematical topics, and between mathematical topics and other topics. The results of the analysis conducted show that the achievement of mathematical connection ability for each indicator is still not achieved, so students' mathematical connection ability is still relatively low.Â
