“…Hasil evaluasi proses aktivitas kritis siswa sekolah dasar dalam memecahkan masalah berada dalam kategori rendah (Amir, 2015). Aktivitas berpikir kritis siswa sekolah dasar kelas awal masih menunjukkan adanya kelemahan dalam berargumen secara logis (Altintas & Ozdemir, 2012;Rogers & Kosko, 2019). Performa keterampilan berpikir kritis siswa sekolah dasar dalam menyelesaikan tugas matematis masih menunjukkan adanya kelemahan dalam hal memformulasikan masalah (Maricic& Spijunovic 2015).…”

Penelitian ini bertujuan untuk meningkatkan performa (aktivitas dan keterampilan) berpikir kritis siswa sekolah dasar dalam pembelajaran matematika melalui penerapan model group investigation (GI). Metode penelitian menggunakan penelitian tindakan kelas dengan model Kemmis dan Taggart. Subjek penelitian yaitu siswa kelas IV SDN Jenggot berjumlah 18 siswa pada semester ganjil tahun ajaran 2021-2022. Teknik pengumpulan data adalah observasi aktivitas kritis dan tes berpikir kritis. Analisis data berpatokan pada indikator keberhasilan dengan minimal nilai aktivitas kritis dan keterampilan berpikir kritis minimal 70% tuntas. Hasil penelitian adalah aktivitas kritis pada akhir siklus mengalami peningkatan 23,06%, sedangkan keterampilan berpikir kritis pada akhir siklus mengalami peningkatan 13,25%. Oleh karenanya, penerapan model GI dapat meningkatkan performa berpikir kritis siswa sekolah dasar.

“…Hal ini relevan dengan hasil penelitian Wijaya et al (2016) yang menyatakan bahwa KKM siswa perempuan cukup baik dari pada laki-laki. Potensi KKM terkait dengan dukungan keterlibatan siswa dalam berargumentasi matematis sehingga mereka dapat menjelaskan dan menyelesaikan masalahnya (Kosko et al, 2014;Rogers & Kosko, 2018). Namun demikian dalam kemampuan komunikasi secara lisan, siswa laki-laki cenderung tidak bertele-tele, menjawab dengan tegas, percaya diri, lebih banyak menggunakan imajinasi, dan kritis dibandingkan siswa perempuan, meskipun ada beberapa bagian yang kurang tepat dijawab.…”

The emphasis of mathematics learning, especially students' communication skills, needs to be considered from gender equality in solving mathematical problems. This study aims to describe: 1) the potential mathematical communication skills of students based on gender; 2) gender equality in communicating mathematical problem solving; and 3) the suitability of the form of the model or the applied form to develop students' mathematical communication skills based on gender at school. This research is a descriptive qualitative research conducted on all junior high school students in Langsa with a purposive sampling technique of 283 students. The data were collected through mathematical communication skills and questionnaire tests which were analyzed descriptively using the concept of Miles and Huberman. The results showed that: 1) mathematical communication skills of female students were better than male students in solving mathematical problems; 2) mathematical communication skills of male students are better in suburban schools and female students are better in downtown schools; and 3) learning implementation plans are still limited in emphasizing mathematical communication skills and learning tends to be cooperative and individual. It is recommended that learning plans refer to developing mathematical communication skills that pay attention to students' gender equality in order to optimize mathematical problem solving.

“…Previous research specifically states that sociomathematics norms are related to mathematical argumentation, namely how students carry out the process of interaction and negotiation to understand mathematical concepts (Moutsios-rentzos et al, 2019;Rogers & Kosko, 2019;Schwaighofer et al, 2017). Other than sociomathematic norms are closely related to negotiations on what is called problem-solving procedures, such as what is acceptable, regarding the formulation of effective procedures (Putri et al, 2015;Widodo et al, 2019Widodo et al, , 2020Widodo & Purnami, 2018).…”

This study aims to describe the sociomatematical norms that are owned by students when learning mathematics in class. The subjects of this study were students of class VII-A Jakarta 113 Junior High School. The research method used is descriptive qualitative method. This research uses sociomatematical norms questionnaire and interview. Based on the results of the study, there were 9 students who had very good sociomatematical norms categories with a total percentage of indicators of 81% and there were 14 students who had good sociomatematical norms categories with a total percentage of indicators of 72%. The results showed that very good sociomatematical norms owned by students would affect the high results obtained by students in mathematics learning and good sociomatematical norms would affect the moderate and low results obtained by students in learning mathematics.
