Abstract

AbstrakMahasiswa calon guru yang memiliki kemampuan berpikir kritis matematis diharapkan dapat memecahkan permasalahan yang berkaitan dengan konsep matematika ataupun konsep didaktiknya. Fokus keterampilan berpikir kritis matematis pada mahasiswa calon guru adalah kemampuan untuk mengidentifikasi permasalahan, mencari strategi, melakukan refleksi kembali, dan menganalisis permasalahan matematika. Penelitian ini bertujuan untuk mendesain soal berbasis masalah yang valid dalam meningkatkan kemampuan berpikir kritis matematis mahasiswa calon guru dalam berbagai materi pendidikan menengah. Penelitian ini mengambil jenis penelitian pengembangan, terdiri dari studi literatur, observasi, dan pengembangan soal. Kesimpulan dari penelitian ini hasil validasi expert menunjukan nilai validitas muka 80,35% dan nilai validitas isi 86,85%. Hal ini berarti soal-soal berbasis masalah untuk meningkatkan keterampilan berpikir kritis matematis dapat digunakan sebagai bahan pembelajaran dalam mata kuliah Kapita Selekta Matematika Pendidikan Dasar 1 untuk mahasiswa calon guru. AbstractProspective teacher students who can think critically mathematically are expected to be able to solve problems related to mathematical concepts or didactic concepts. The focus of mathematical critical thinking abilities on prospective teacher-students is the ability to identify problems, find strategies, reflect, and analyze mathematical problems. This study aims to design a valid and practical problem-based activity question to improve students' mathematical critical thinking abilities of prospective teachers in various secondary education materials. This research takes the type of Research and Development, consisting of a study of literature, observation, and development of questions. The conclusion from this study the results of expert validation showed an advance validity value of 80.35% and a value of content validity of 86.85%. This means that problem-based activity questions to improve mathematical critical thinking abilities can be used as learning material in the Kapita Selekta Mathematics Basic Education 1 course for prospective teacher students.

Abstract

AbstractThe teke (gecko) and biklusu (lizard) motifs in lotis woven fabrics represent symbolic and spiritual values in Amanuban culture while also containing mathematical structures. However, these mathematical aspects are rarely explored, and local weaving traditions are seldom integrated into formal mathematics learning. This gap has led to limited use of cultural resources in supporting students’ understanding of geometry. Therefore, this study identifies the types of frieze patterns in three variants of these motifs and explores their potential for integration into mathematics education. A descriptive qualitative approach was employed, utilizing direct observation, documentation, and interviews with weavers and cultural elders. The primary data consisted of visual representations of the three motifs, which were analyzed through isometric transformations including translation, vertical and horizontal reflection, 180° rotation, and glide reflection. The classification was based on the seven types of frieze patterns as defined by the one-dimensional isometry group theory. The findings reveal that two motifs correspond to the F6 frieze pattern type, while one aligns with the F7 type, demonstrating varying degrees of geometric symmetry complexity. The teke and biklusu motifs can serve as effective contextual tools for mathematics instruction across educational levels, from pattern recognition in primary school to advanced discussions of isometry group theory in higher education. This approach aligns with the goals of the Merdeka Curriculum by linking mathematics learning to meaningful local contexts.
