Abstract

Mathematics plays an important role in various areas of daily life and helps develop logical, critical, and systematic thinking patterns, and problem-solving abilities. However, the mathematics learning process often experiences obstacles both from internal factors such as students' negative attitudes, low interest in learning, and weak motivation, as well as external factors such as lack of teacher focus and minimal family support. Ethnomathematics, namely mathematics integrated with local culture, has emerged as an effective method to help students understand mathematical concepts more easily and interestingly. This research was conducted on the process of making Sidikalang coffee at UD (trading business) Kopi Keke, Dairi, North Sumatra, which combines ethnomathematics with mathematics learning. Through qualitative methods with an ethnographic approach, this research identifies mathematical concepts contained in the six stages of coffee making, namely drying, pounding, roasting, grinding, packaging, and marketing. The research results show that this process includes the concepts of social arithmetic, calculation, time comparison, plane geometry, space geometry, and measurement so that it can support mathematics learning that is easy for students to understand.

Abstract

Penelitian ini bertujuan untuk mengetahui perbedaan kemampuan berpikir kritis matematis siswa melalui model pembelajaran Discovery Learning dan model pembelajaran Problem Based Learning di MTS AL-Mushlihin. Penelitian ini merupakan penelitian eksperimen dengan jenis quasi eksperiment (eksperimen semu) dan menggunakan pendekatan kuantitatif. Penelitian ini melibatkan dua kelas yaitu kelas eksperimen I yaitu dengan menggunakan model discovery learning dan kelas eksperimen II dengan menggunakan model problem based learning. Hasil temuan ini menunjukkan bahwa: Terdapat perbedaan kemampuan berpikir kritis siswa yang diajar menggunakan model pembelajaran discovery learning dan model pembelajaran problem based learning pada materi Bangun Ruang Sisi Datar dengan t-hitung = 2,59 > t-tabel = 2,009. Hal ini menunjukkan model pembelajaran discovery. ABSTRACT This research aims to determine the differences in students' mathematical critical thinking abilities through the Discovery Learning learning model and the Problem Based Learning learning model at MTS AL-Mushlihin. This research is experimental research with a quasi-experimental type (pseudo-experiment) and uses a quantitative approach. This research involved two classes, namely experimental class I using the discovery learning model and experimental class II using the problem based learning model. The results of these findings indicate that: There is a difference in the critical thinking abilities of students who are taught using the discovery learning model and the problem based learning model in the Flat-Side Building material with t-hitung = 2.59 > t-tabel= 2.009. This shows the discovery learning model.

Abstract

Penelitian ini bertujuan untuk meneliti efek atau pengaruh dari penerapan model pembelajaran kooperatif tipe CIRC (Cooperative Integrated Reading and Composition) terhadap kemampuan siswa dalam menyelesaikan soal cerita yang memerlukan ketrampilan berpikir tingkat tinggi (Higher Order Thingking Skills atau HOTS). Metode yang digunakan dalam penelitian ini adalah quasi-experiment dengan desain Pre-test Post-test control group. Validasi instrumen dilakukan melalui uji validitas, reliabilitas, daya beda dan taraf kesukaran soal. Analisis data menggunakan uji t untuk menguji perbedaan rata-rata hasil pre-test dan post-test antara kedua kelompok. Hasil penelitian menunjukkan adanya perbedaan signifikan dalam kemampuan menyelesaikan soal cerita tipe HOTS antara kelas eksperimen dan kelas kontol. Nilai rata-rata post-test kelas eksperimen (83,78) lebih tinggi dibandingkan kelas kontrol (74,81). Temuan ini menunjukkan bahwa pembelajaran kooperatif tipe CIRC efektif dalam meningkatkan kemampuan menyelesaikan soal cerita tipe HOTS ABSTRACT This research aims to examine the effect or influence of implementing the CIRC (Cooperative Integrated Reading and Composition) cooperative learning model on students' ability to solve story problems that require higher order thinking skills (HOTS). The method used in this research was a quasi-experiment with a Pre-test Post-test control group design. Instrument validation is carried out through tests of validity, reliability, distinguishability and level of difficulty of the questions. Data analysis used the t test to test the difference in average pre-test and post-test results between the two groups. The research results showed that there was a significant difference in the ability to solve HOTS type story problems between the experimental class and the control class. The average post-test score for the experimental class (83.78) was higher than the control class (74.81). These findings indicate that CIRC type cooperative learning is effective in improving the ability to solve HOTS type story problems.
