Learning mathematics with a daily life orientation creates a real and optimal learning experience for students, especially in the cultural sphere, which also supports students' mathematical communication skills. This research aims to analyze the mathematical communication skills of junior high school students through ethnomathematics-based Realistic Mathematics Learning, especially at Tikus Temple, Mojokerto Regency. This research is descriptive quantitative research with an ethnographic approach. The subjects used were one class of SMP 48 Surabaya students. Quantitative data was obtained based on students' post-test results. The research results showed that the students' mathematical communication ability test data was normally distributed with a significance value based on the Kolomogorov-Smirnov test of 1,116. Twenty students achieved completion of KKM 65. The results of the One-Sample Statistics test show that the average student calculated value is 72,16 with a standard deviation of 14,593 and a standard error of 2,664. The One-Sample Test results also show a sig. (2-tailed) value of 0,012, meaning that the average value of students' mathematical communication test results is more than or not equal to 70. The minimum completion proportion test results show that the value of tcount ttable so that students' average mathematical communication ability is not equal to 65 and more than 70%.

Penerapan kurikulum Merdeka, seorang guru dituntut mengarahkan proses pembelajaran menjadi lebih inovatif, kreatif, menyenangkan, dan memerdekakan siswa untuk belajar melalui pengembangan LKPD berbasis MEA. 26 calon guru matematika terlibat dalam penelitian ini untuk mengidentifikasi kompetensi calon guru matematika dalam mengembangkan LKPD ditinjau dari perspektif MEA. Penelitian deskriptif kuantitatif ini melibatkan calon guru yang menempuh Pendidikan di Universitas PGRI Adi Buana Surabaya dan Universitas Wijaya Kusuma Surabaya. Data dikumpulkan melalui dokumentasi dari calon guru ketika menempuh mata kuliah Program Pengalaman Lapangan. Data dianalisis menggunakan prosentase kompetensi calon guru berdasarkan perspektif MEA. Hasil analisis data berdasarkan indikator perspektif MEA diperoleh 76,92% calon guru belum kompeten mengembangkan LKPD dan sisanya kompeten. Akan tetapi, ada kelemahan dari LKPD yang dikembangkan oleh calon guru matematika yaitu belum memenuhi prinsip self assessment yang seharusnya ada pada LKPD dan pemberian Latihan mandiri perlu mendapatkan perhatian lebih lanjut. Implikasinya perlu ada pembekalan bagi pengampu mata kuliah yang mengajarkan pengembangan LKPD untuk memperhatikan sasaran pembuatan LKPD yang memperhatikan latar belakang siswa secara keseluruhan sehingga dapat mengakomodir situasi di kurikulum Merdeka. Para pengampu mata kuliah juga perlu mengikuti perkembangan masa yang ada agar para calon guru tidak mengalami kebingungan dalam mengonstruk pengetahuan melalui petunjuk di LKPD.

Technology and education go hand in hand with the needs of Generation Z, who demand ease in learning. Various kinds of information in digital form will be easily accessible with increasingly sophisticated technological developments, especially in learning. The use of digital books in the form of flipbooks, which are used to train creative thinking and can be used as a means of teaching mathematics calculations for prospective Early Childhood Education teacher students, still needs to be found. So, this research aims to develop a digital book product called FLOC (Flipbook Competence) as a teaching aid for prospective Early Childhood Education teacher students to train in collaborative and creative thinking. This research is development research with a method that refers to the development stages of the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). This research produces a product in the form of a flipbook application based on FLIPHTML5, which can be accessed via computer or Android devices. The results of product trials show that FLOC (Flipbook Competence) can attract and motivate prospective PAUD teacher students to teach the concept of Numbers. The implication is that FLOC (Flipbook Competence) is also considered to have ease of use and good visualization and to attract students' interest in learning.

Solving mathematics word problem is an example of problem solving which is helpful to everyday life, but not all students can easily solve it. Most students have difficulty and errors in solving it. Researchers often find in journal information that students struggle to complete a story. In some cases, it is a matter of mathematically shaped stories in the matter of cartesian coordinates. More than a few students are uneasy to solve mathematics word problem. In fact, many students have not known the concept of cartesian coordinates. The purpose of this study is to describe the type of error and the factors that cause students to make a mistake in solving mathematics word problem especially cartesian coordinates with the correct step of understanding the problem, formulating a plan, carrying out a plan, and examining the answer. It is a qualitative study carried out at public junior high school 2 Sukodono. The data of this study consist of data on written tests and interviews with the group A of VIII-A SMPN 2 Sukodono students. The method of data collection of this research is tests and interviews. The method of data analysis in this study id data reduction, test results analysis, display data, and withdrawal or verification. The subject of this study the three students who the most errors. Studies show made that the flaw of subjects 1, subject 2, and subject 3 lie in the understanding of the problem, formulating a plan, carrying out a plan, and examining answer. According to Polya, the three students had problem at the stage of solving mathematics word problem therefore, the three subjects could not continue the work at the next phase of formulalting a plan, carrying out a plan, and examining answer. The cause of the students’ mistakes is that the students did not understand the concept of the matter’s coordinates. Students didm’t understand the problem well, so they didn’t understand the proper problem settlement planning. In short, the results achieved by the student are inadequate.

This study aims to determine the effect of a realistic mathematical approach on students' mathematical communication skills, especially in algebraic material. This research was conducted at SMP Negeri 21 Surabaya, with a sample of 72 students in VII class and divided into two classes, namely the experimental class, which applied a realistic mathematical approach, and the control class, which applied the scientific approach. After learning, students are given a test of students mathematical communication tests and analyzed using a t-test to determine if there are differences in the results of students' mathematical communication tests between the two classes. The study's results revealed differences in students’ mathematical communication tests between the experimental and control classes. Furthermore, based on the average results of the mathematics communication test, the students showed that the experimental class was higher than the control class. So the realistic mathematics approach has a better effect on students' mathematical communication than the scientific approach.

Teori graf merupakan bagian dari mata kuliah matematika diskrit yang mencakup konsep teori graf. Tujuan mengajarkan teori graf di jenjang pendidikan tinggi untuk memahami konsep Graf melibatkan kemampuan memecahkan masalah yang kompleks dan mengajarkan berpikir kritis bagi mahasiswa. Salah satu topik yang sering menjadi fokus dalam pembelajaran ini yaitu Graf Euler. Pemahaman tentang Graf Euler melibatkan keterampilan kritis dalam pemikiran dan konstruksi bukti matematis. Penelitian ini dilakukan dengan menggunakan perspektif Toulmin, yang merupakan teori tentang konstruksi bukti matematis. Teori ini menggambarkan bahwa konstruksi bukti matematis terdiri dari klaim, data, penjelasan, kualifikasi, dan rebuttal. Subjek dalam penelitian ini yaitu mahasiswa aktif Program Studi Pendidikan Matematika Universitas PGRI Adi Buana Surabaya angkatan 2022 yang aktif mengampu mata kuliah matematika diskrit. Tujuan dari penelitian ini untuk mengeksplorasi konstruksi bukti matematis yang dilakukan oleh mahasiswa dalam menyelesaikan soal Euler. Berdasarkan hasil analisis dalam penelitian ini subjek mampu menyelesaikan soal dengan memenuhi perspektif Toulmin, kedua subjek sudah mampu menjelaskan dari apa yang sudah dikerjakan berdasarkan hasil wawancara, yang artinya subjek sudah mampu mengeksplor konstruksi bukti matematis soal Graf Euler berdasarkan kerangka perspektif Toulmin. Rekomendasi dari hasil penelitian ini, untuk perpekstif Toulmin bisa diterapkan pada penerapan soal Graf Hamilton.
