<span lang="EN-GB">Penelitian ini bertujuan untuk mengetahui bagaimana penerapan dan pengaruh adanya matakuliah matematika islam terhadap sikap matematis mahasiswa. Matematika islam sebagai salah satu upaya penguatan literasi matematika. Penelitian dilakukan terhadap beberapa mahasiswa semester lima yang menempuh matakuliah matematika islam sebagai matakuliah pilihan. Analisis data menggunakan penelitian kuasi eksperimen dengan dua kelompok eksperimen. Data diperoleh dengan lakukan observasi dan pemberian angket kepada mahasiswa. Hasil penelitian menunjukkan bahwa ada pengaruh yang signifikan matakuliah matematika islam terhadap sikap matematis mahasiswa. Hal ini ditunjukkan dengan adanya perbedaan sikap matematis antara mahasiswa yang menempuh dengan yang tidak menempuh matakuliah matematika islam.</span>
Mathematics is a discipline that can improve thinking skills. However, in reality, the mathematics thinking skills of elementary school students are still low. This is because the mathematics learning used is not optimal and still uses conventional learning. In the process of mathematics learning, there is an integration of character values with mathematics material. Character building through mathematics learning has not been done relatively. The current mathematical concept can be related to cultural activities called ethnomathematics. Through ethnomathematics, mathematics learning becomes more realistic. The purpose of this research is to build students’ character and improve student’s mathematic learning achievement through developing student worksheets with a mathematical approach based on ethnomathematics. The methods of the research were research and development by using steps including preliminary study, design, development, and dissemination. The result of the research is student's worksheets fulfill valid, practical, and effective criteria. The result of the validity of teaching media shows that the average number is 96 % with very good criteria. The effectiveness test shows that there is a distinction of student’s achievement before and after the treatment and the student’s achievement on average is increased. Based on the analysis of student's answers on student worksheets, four characters are built through the learning process with a realistic mathematic approach based on ethnomathematics, such as creativity, independence, curiosity, and nationality.
Keywords: character building, realistic mathematics learning, ethnomathematics.
Pelaksanaan program pemberdayaan masyarakat bertema penguatan pembelajaran matematika geometri di SD/MI Berbasis MBNK (Matematika Berwawasan Nasionalisme dan Kemandirian mencakup empat kegiatan, yaitu: Pertama, Pengenalan dan sosialisasi aplikasi geometri MBNK, Kedua, Pembahasan materi geometrid an soal-soal geometri MBNK, Ketiga, Pengembangan LKS Geometri MBNK, dan Keempat, Pelatihan penggunaan aplikasi geogebra . Metode yang digunakan dalam kegiatan pengabdian masyarakat ini adalah: ceramah, demonstrasi, praktik langsung, tanya jawab, dan penugasan. Program berlangsung selama empat kali tatap muka secara bertahap dan berkelanjutan. Peserta yang mengikuti program sebanyak 40 guru SD dan MI di Kabupaten Pekalongan. Program pemberdayaan peningkatan kapasitas guru ini berdampak positif kepada guru SD/MI di Kabupaten Pekalongan. Sebelum diadakan kegiatan workshop, guru merasa kewalahan dan jenuh dalam pembelajaran daring selama masa pandemi. Guru belum mahir dalam menggunakan aplikasi dalam pembelajaran matematika. Setelah diadakan kegiatan dan diadakan evaluasi, guru menjadi lebih bersemangat dalam pembelajaran daring. Kemampuan guru dalam menggunakan aplikasi pemebalajran matematika salah satunya geogebra menjadi meningkat.
