Abstract

The aim of this research is to compare the mathematical critical thinking abilities of students whoreceive a scientific approach with students who receive conventional learning. This study uses experimentalmethods. The subjects were MTSN 2 Medan students who were randomly selected from two classes in classVIII. These two classes were chosen randomly to be used as the experimental class and control class. Theexperimental class received learning with a scientific approach, while the control class received conventionallearning. The mathematical critical thinking ability test is the instrument used. The results of data analysis showthat scientific learning methods improve students' mathematical critical thinking abilities.

Abstract

This study examines ethnomathematics exploration in the architecture of Nurul Anwar Mosque as a way for students of MTs. Mambaul Ulum Banjarejo to learn geometry. The architectural elements of this mosque reflect various mathematical concepts, such as plane shapes (rectangle, rhombus, circle) and solid shapes (half sphere, cylinder, cuboid), and geometric transformations (rotation, reflection). This study uses a qualitative descriptive approach that uses ethnomathematics exploration. Data were collected through observation, interviews, documentation, and geometric measurements. The results of the study indicate that geometric elements of the mosque can be integrated into mathematics learning to improve students' understanding of geometric concepts contextually and applicatively. This approach not only makes learning more relevant and interesting, but also preserves local cultural values. In culture-based education, using ethnomathematics can strengthen students' identity in Islamic education and instill an appreciation for cultural heritage and can improve understanding of mathematics learning.
