Abstract

Education in the present has become a necessity, the need for knowledge gained through the learning process both in school and learning from the environment of residence. Mathematical skills are important for everyday life, when students work in activities that are based on everyday life situations; they see ways of applying the mathematical skills they are learning to the real world. Thelearning strategy REACT is one of the learning strategies that use the environment as a source of learning. Besides the teaching learning process with active student learning methods (CBSA) the teacher must be more active in preparing lesson material, planning the process to be carried out such as RPP, preparing evaluation such as LKS and follow-up. From the results of the study the development of learning tools for student activities reached 91.25% and the success rate of students reached 70%. Thus the development of a square and rectangular learning device using theREACTstrategy has a good effect on student activity and student learning outcomes

Abstract

Kehidupan masyarakat di pesisir pantai sangat kaya dengan konsep-konsep matematika. Sebagai budaya, aktivitas bertukar barang berisi ide matematika karena matematika pada dasarnya merupakan fenomena budaya dan sebagai aktivitas manusia serta setiap budaya mengembangkan bentuk matematika mereka sendiri sesuai dengan tuntutan dan kebutuhan lingkungan dan tujuan masyarakat. Pendekatan etnomatematika merupakan suatu proses pembelajaran yang mengintegrasikan budaya dan aktifitas masyarakat atau interaksi sosial dalam membangun konsep matematika. Pemahaman konsep nilai tempat bilangan tiga angka berawal dari ide bertukar sepuluh satuan menjadi satu puluhan dan sepuluh puluhan menjadi satu ratusan. Penelitian ini bertujuan untuk mensuport pemahaman siswa dalam memahami konsep nilai tempat lewat salah satu konteks tradisi/interaksi social yang berlangsung dalam masyarakat yaitu aktifitas bertukar kulibia. Penelitian ini difokuskan pada desain lintasan belajar (Hypothetical Learning Trajectory) siswa yang berkembang dari level informal menuju ke level formal.  Metode penelitian desain (design research) digunakan untuk menjawab tujuan penelitian. Penelitian ini menggambarkan bagaimana aktifitas bertukar kulibia dapat membantu siswa kelas 2B SD Negeri 2 Desa Latuhalat mamahami nilai tempat tiga angka. Penggunaan aktifitas bertukar kulibia dan diskusi siswa menunjukan pemahaman siswa terhadap konsep nilai tempat berkembang dari level informal ke level formal

Abstract

Pembuktian teorema atau lemma dalam mata kuliah Analisis Real masih sulit dipahami oleh mahasiswa Pendidikan Matematika FKIP Unpatti dikarenakan masih banyak mahasiswa yang belum mengerti materi dasar pendukungnya yaitu metode-metode dalam pembuktian matematika dengan baik. Padahal materi tersebut sudah pernah dipelajari pada mata kuliah-mata kuliah dasar. Dengan demikian dalam penulisan ini dibahas tentang desain lembar kerja mahasiswa (LKM) dengan menggunakan metode penemuan terbimbing yang dapat digunakan untuk membantu mahasiwsa program studi pendidikan matematika FKIP Unpatti untuk mempelajari materi sistem pembuktian

Abstract

This study aims to describe the perceptions of prospective students in the first year in validating mathematical proof. This student's perception is discussed based on the answers given to the proof of a theorem. This research is a qualitative research. The subjects in this study were three students from the second semester mathematics education study program at a university in East Java. Research subjects were chosen deliberately with the following considerations: prospective teacher students who use examples in making mathematical proof and good communication skills make research can facilitate students' perceptions in writing mathematical proof. The results showed that students had perceptions about who gave several examples so that the proof was called valid, one example of denying it could prove it was invalid and using formal proof that proved it could be proven valid

Abstract

Topik matematika dasar merupakan fokus utama saat mempersiapkan mahasiswa baru masuk sebelum masuk perkuliahan di jenjang perguruan tinggi. Oleh karena itu, mahasiswa harus dapat memahami konsep dari beberapa topik matematika dasar ini dengan baik. Tujuan penelitian ini adalah untuk mendeskrpsikan kesalahan-kesalahan dalam memahami topik-topik matematika dasar, yaitu topik himpunan, relasi, fungsi, matriks, vektor, limit, turunan dan integral. Penelitian ini menggunakan metode penelitian deskriptif kualitif dengan subjek penelitian adalah mahasiswa baru tahun akademik 2020/2021 pada Program Studi Pendidikan Matematika FKIP Unpatti. Instrumen dalam penelitian ini berupa soal tes yang terdiri dari 7 soal tentang topik-topik matematika dasar. Hasil penelitian menunjukkan bahwa mahasiswa melakukan beberapa kesalahan di antaranya kesalahan faktual, kesalahan prosedural, kesalahan konseptual dan kecerobohan

Abstract

Permutations and combinations are one of the materials in discrete mathematics courses that have many benefits in everyday life and are closely related to the context of real life. However, students need to improve in solving permutation and combination problems. This study aims to describe the errors made by students in solving permutation and combination problems. The research subjects comprised 25 first-semester students of the 2021/2022 academic year of the Mathematics Education Study Program, FKIP Unpatti. The research method used is descriptive qualitative. The research instrument consisted of 6 test questions related to permutations and combinations. The results showed that most students made mistakes because they needed help understanding the statement (58%). In addition, students also made mistakes in remembering value parameters (13%), paying attention to order (10%), recognizing objects (8%), using formulas (7%), and errors in performing arithmetic operations (4%). The implications of this research are expected to be able to contribute to lecture activities in the first year
