Abstract

AbstractThis research is motivated by the low ability of students' mathematical representation. Therefore, the researcher wanted to know what difficulties the students experienced when working on questions about representation with cube and block material. This research approach is qualitative with a descriptive method. This research was conducted at SMP Negeri 2 Dawuan with the research subjects of 3 students of class VIII. The research instrument used was a test of mathematical representation ability and student interviews. The results show that the three subjects studied have not achieved the mathematical representation ability indicator. The factors are 1) lack of understanding of the contents of the questions, 2) unable to represent the meaning of the story problems, 3) lack of accuracy in calculating, 4) not being able to represent the questions in picture form. Efforts in overcoming these difficulties are 1) repeating the material that has been delivered outside of class hours, 2) practicing a lot of varied questions, namely from easy questions to more difficult questions, the level of completion, 3) studying the material after and before being taught in order to minimize that difficulty. Occurs, 4) discussing with friends who better understand the material if there is a material that has not been understood, 5) the teacher pays more attention to the student's representation ability during learning.Keywords: Mathematical Ability, Representation Ability, Cubes and BlocksAbstrakPenelitian ini dilatarbelakangi oleh masih rendahnya kemampuan representasi matematis siswa. Maka dari itu peneliti ingin mengetahui kesulitan apa yang dialami siswa saat mengerjakan soal tentang kemampuan representasi dengan materi kubus dan balok. Pendekatan penelitian ini adalah kualitatif dengan metode deskriptif. Penelitian ini dilaksanakan di SMP Negeri 2 Dawuan dengan subjek penelitian sebanyak 3 siswa kelas VIII. Instrumen penelitian yang digunakan adalah tes soal kemampuan representasi matematis dan wawancara siswa. Hasil menunjukkan bahwa dari ketiga subjek yang diteliti belum bisa mencapai indikator kemampuan representasi matematis. Faktor-faktornya adalah 1) kurangnya memahami isi dari soal, 2) belum bisa merepresentasikan makna dari soal cerita, 3) kurangnya ketelitian dalam melakukan perhitungan, 4) belum bisa merepresentasikan soal dalam bentuk gambar. Upaya dalam mengatasi kesulitan tersebut adalah 1) mengulang kembali materi yang telah disampaikan diluar jam pelajaran, 2) banyak berlatih soal yang bervariasi yaitu dari soal yang mudah ke soal yang lebih sulit tingkat penyelesaiannya, 3) mempelajari materi sesudah dan sebelum diajarkan agar meminimalisir kesulitan itu terjadi, 4) berdiskusi dengan teman yang lebih paham materi tersebut apabila terdapat materi yang belum dipahami, 5) guru lebih memperhatikan kemampuan representasi siswa pada saat pembelajaran. Kata Kunci: Kemampuan Matematis, Kemampuan Representasi, Kubus dan Balok

Abstract

Penelitian ini mengungkapkan bahwa mahasiswa tingkat tiga program studi Pendidikan Matematika memiliki permasalahan pada saat persiapan pelaksanaan program PPL. Pada observasi awal masih banyak mahasiswa yang tidak memiliki kepercayaan diri ketika diberikan peluang untuk mengajar di tingkat Sekolah Menangah Atas. Meskipun berbagai upaya dilakukan seorang dosen guna meningkatkan kepercayaan diri mahasiswa pada perkuliahan pembelajaran mikro. Dengan demikian, penelitian ini memiliki rumusan masalah yakni menganalisa self confidence dan keterampilan bertanya mahasiswa pada perkuliahan pembelajaran mikro. Adapun metode penelitian ini menggunakan deskriptif kualitatif karena relevan dilihat dari proses awal penelitian hingga penarikan kesimpulan. Berdasarkan hasil penelitian diperoleh kesimpulan bahwa : 1) kemampuan mahasiswa dalam mengajukan pertanyaan tingkat dasar tergolong pada kategori sangat baik hal ini dibuktikan hampir keseluruhan mahasiswa mampu melakukan keterampilan ini, sedangkan kerampilan bertanya lanjut masih 70% mahasiswa  melakukannya sisanya belum melakukan.   2) terdapat hubungan yang kuat antara self confidence dengan keterampilan bertanya pada perkuliahan pembelajaran mikro.  Kata Kunci. Pembelajaran mikro, keterampilan bertanya, self confidence.

Abstract

Understanding mathematical and mathematical concepts is one of my fundamental abilities. Therefore, it is necessary to teach mathematics by emphasizing concept understanding so that students are trained to solve problems with the concepts they understand appropriately. This study aims to analyze the knowledge of mathematical concepts of students at junior high school level grade VIII on linear function material. This research is qualitative research with a descriptive method. The research subjects were VIII grade students, as many as 33 students. Data collection through two description questions was then analyzed according to the ability of high, medium, and low student categories. Furthermore, direct interviews were conducted to obtain more in-depth information about students' understanding of mathematical concepts. The results showed that 39.39% of students had high-category mathematical concept understanding ability (ST), 6.06% of students in the medium category (SS), and 54.55% of students in the low category (SR). ST fulfills all indicators with the correct answer, and SS fulfills all indicators, but the answers produced could be more precise. SR cannot apply concepts, so it only fulfills some indicators, which results in errors in solving problems.

Abstract

Mathematical reasoning and mathematical communication are two fundamental dimensions of learning mathematics in higher education that are often investigated separately. This article aims to reconceptualize their relationship through an epistemic–discursive perspective, viewing reasoning and communication as mutually constitutive practices in undergraduate students’ mathematical activity. The study employs a systematic literature review of articles published in internationally reputable journals over the last decade that address mathematical reasoning, communication, argumentation, and discourse in higher education contexts. The synthesis was conducted using thematic synthesis enriched by theoretical analysis. The findings indicate that mathematical reasoning cannot be fully understood without considering the communicative dimension and the discursive norms that mediate it, while mathematical communication functions as a medium of thinking and meaning-making rather than merely a means of expression. Based on these findings, the article proposes an integrative conceptual framework that positions mathematical argumentation and epistemic norms as central mediators between students’ reasoning and communication. This study contributes theoretically by offering a reconceptualization of reasoning and communication that is relevant for research and teaching in undergraduate mathematics education.

Abstract

Mathematical conceptual understanding is a fundamental goal of mathematics education, particularly in higher education where students are required to engage with abstract concepts, formal structures, and relationships among mathematical ideas. However, research consistently indicates that instructional practices tend to prioritise procedural success over the development of deep conceptual understanding. This article aims to systematically synthesise research on undergraduate students’ mathematical conceptual understanding by adopting an epistemic–discursive perspective. A systematic literature review was conducted on Scopus-indexed journal articles published between 2014 and 2024 that focus on higher education mathematics. The findings indicate that mathematical conceptual understanding is constructed through the interaction of mathematical representations, discourse and communication, mathematical reasoning, and epistemic norms embedded in learning environments. The review also reveals that conceptual understanding should not be viewed solely as an individual cognitive attribute, but rather as a practice that develops through students’ participation in formal mathematical activity. Based on this synthesis, the article proposes an integrative conceptual framework that positions mathematical conceptual understanding as an epistemic–discursive practice. This framework is expected to contribute to theoretical advancement and inform future research and instructional design in undergraduate mathematics education.
