Abstract:
The social interactions that occur between individuals in mathematics are called sociomatematics. Sociomatematic norms are rules derived from mathematical values that are brought into a social context. Sociomatematic norms are seen as being able to improve students' understanding. The main focus of this research are, (1) Analyzing social content in Elementary School Mathematics Learning courses; (2) Describing the social interaction process on the research subject; and (3) Describe the relationship between social interactions and mathematics learning outcomes. This type of research is quantitative with a descriptive approach. The research subjects were 100 PGSD students. The data collection technique used a survey method and the analysis of the results of the student mathematics examination. Data analysis used simple linear regression analysis. From the research, the results obtained: (1) Mathematical content in the lecture process has been raised by the lecturer. The lecture system in the form of group discussions can improve students' communication skills, courage and cooperation. (2) An overview of student social interactions can be modeled. The social interaction model shows that social interaction can take the form of associative and dissociative. (3) There is a relationship between social interaction and mathematics learning outcomes. This relationship is quite strong, and social interactions have an effect on student mathematics learning outcomes.

Abstract:
The purpose of this study was to analyze the renewal of the integrated curriculum during the Covid-19 pandemic. The Covid-19 outbreak has had a major impact on various sectors, one of which is education. The world of education also feels the impact. As a teacher, it is necessary to create learning that can support the state of the world of education which is currently being carried out during the Covid-19 pandemic. From the renewal of the curriculum, the Cooperative Make a Match is applied, assisted by learning videos, which can improve students' understanding of mathematical concepts. Learning Make A Match is a learning model that can help students be more confident in solving a problem and with the help of learning videos of students in understanding learning material from far away without having to meet face to face with teachers in accordance with the rules of education during the Covid pandemic. -19. Based on the results of the treatment research analysis using the Make A Match cooperative learning model assisted by video learning in the experimental class is better than the conventional learning model in the control class.

Abstract:
Kemampuan representasi matematika merupakan salah satu tujuan umum dari pembelajaran matematika di sekolah. Dengan representasi, masalah yang semula terlihat sulit dan rumit dapat dilihat dengan lebih mudah dan sederhana, sehingga masalah yang disajikan dapat dipecahkan dengan lebih mudah. Tapi kenyataannya kemampuan representasi di Indonesia masih tergolong rendah. Oleh karena itu Peneliti tertarik untuk mengetahui kemampuan representasi matematis siswa kelas VI SD Negeri 93 Palembang. Penelitian ini bertujuan untuk mengetahui kemampuan representasi siswa SD pada materi skala. Pendekatan penelitian ini menggunakan tipe penelitian deskriptif kualitatif. Populasi dalam penelitian ini adalah seluruh siswa kelas VI SD Negeri 93 Palembang dengan sampel penelitian adalah sebanyak 21 siswa. Teknik pengumpulan data dalam penelitian ini berupa tes dan wawancara. Selanjutnya data yang didapatkan dianalisis untuk menentukan kemampuan representasi siswa dalam menyelesaikan soal materi skala. Hasil penelitian ini menunjukkan bahwa kemampuan representasi matematis visual dan simbolik siswa dalam menyelesaikan soal matematika materi skala dapat dikategorikan baik dengan persentase 85,71%, sedangkan kemampuan representasi matematis verbal dapat dikategorikan sangat baik dengan persentase 59,52%.

Abstract:
ABSTRAK Penelitian ini bertujuan untuk mendiskripsikan model pembelajaran pencapaian konsep untuk materi segitiga kelas VII dan membandingkan keefektifan model pembelajaran ini dengan model pembelajaran konvensional. Populasi dan sampel yang digunakan adalah siswa kelas VII SMPN 36 Kebonsari, disini peneliti mengembangkan perangkat pembelajaran berupa LKS, soal quis, dan soal THB. Perangkat pembelajaran sebelum digunakan dalam eksperimen telah divalidasi dan telah diuji coba lapangan sehingga memenuhi syarat valid, sensitif, dan reliabel.Rancangan penelitian menggunakan pretes-postes dan menggunakan 2 kelas yaitu kelas eksperimen dan kelas kontrol.Sedangkan metode analisa data yang digunakan adalah analisis kovarian. Hasil analisis data diperoleh model regresi linier kelas eksperimen adalah Y = 52,29 + 0,37X dan model regresi linier untuk kelas kontrol adalah Y = 50,06 + 0,300X . Karena dari uji kesejajaran diperoleh hasil bahwa kedua model regresi linier adalah sejajar sehingga keduanya dapat dibandingkan. Dari sini terlihat bahwa hasil belajar siswa dengan model pembelajaran pencapaian konsep lebih baik daripada hasil belajar siswa dengan model pembelajaran pencapaian konsep. Kata kunci: anakova, model pembelajaran pencapaian konsep, ABSTRACT This study aims to describe the conceptual achievement learning model for the seventh-grade triangle material and to compare the effectiveness of this learning model with conventional learning models. The population and sample used were students of class VII SMPN 36 Kebonsari, here the researcher developed learning tools in the form of worksheets, quiz questions, and THB questions. The learning device before being used in the experiment has been validated and has been tested in the field so that it meets the valid, sensitive, and reliable requirements. The research design used a pretest-posttest and used 2 classes, namely the experimental class and the control class. While the data analysis method used was covariance analysis. The results of data analysis obtained that the experimental class linear regression model is Y = 52.29 + 0.37X and the linear regression model for the control class is Y = 50.06 + 0.300X. Because from the parallelism test, the results show that the two linear regression models are parallel so that they can be compared. From this, it can be seen that the student learning outcomes with the concept achievement learning model are better than the student learning outcomes with the concept achievement learning model. Keywords: ANCOVA, concept achievement learning model,

Abstract:
Matematika berfungsi mengembangkan kemampuan menghitung, mengukur, menurunkan dan menggunakan rumus matematika yang diperlukan dalam kehidupan sehari-hari melalui materi pengukuran dan geometri, aljabar, dan trigonometri. Matematika juga berfungsi mengembangkan kemampuan mengkomunikasikan gagasan dengan bahasa melalui model matematika yang dapat berupa kalimat dan persamaan matematika, diagram, grafik atau tabel. Metode pembelajaran kerja kelompok adalah metode pembelajaran yang dalam menyelesaikan masalah pelajaran dengan cara berkelompok Rumusan masalah dalam penelitian ini adalah: Adakah peningkatan kemampuan memahami persamaan kuadrat dengan metode kerja kelompok siswa semester 5 kelas 9K MTsN 2 Kota Kediri Tahun Pelajaran 2019/2020?. Pendekatan yang digunakan dalam penelitian ini adalah pendekatan kuantitatif, dengan jenis penelitian tindakan. Peneliti terlibat langsung dalam penelitian mulai dari awal sampai penelitian berakhir. Peneliti berusaha melihat, mengamati, merasakan, menghayati, merefleksi dan mengevaluasi kegiatan pembelajaran yang berlangsung. Tahap-tahap pelaksanaan penelitian tindakan terdiri dari perencanaan (planning), pelaksanaan (acting), observasi (obseving), dan refleksi (relecting). Untuk mendapatkan hasil penelitian yang akurat maka data yang telah terkumpul dianalisis secara statistik yaitu mengunakan rumus mean atau rata-rata. Dari hasil penelitian didapatkan bahwa nilai rata-rata prestasi belajar dengan pembelajaran kerja kelompok yang dihasilkan pada siklus I sebasar 67 dan pada siklus II diperoleh nilai rata-rata 78. Ketuntasan belajar pada siklus I baru mencapai 40%, pada siklus II mencapai 81,08%. Mengacu pada hipotesis tindakan yang diajukan dalam penelitian tindakan kelas ini maka dapat disimpulkan bahwa : Ada peningkatan kemampuan memahami persamaan kuadrat dengan metode kerja kelompok siswa semester 5 kelas 9K MTsN 2 Kota Kediri Tahun Pelajaran 2019/2020 Kata kunci: Memahami Persamaan Kuadrat, Metode kerja Kelompok
