Struktur Aljabar mempelajari gabungan satu atau lebih himpunan dengan satu atau lebih operasi biner yang memenuhi kumpulan aksioma. Calon guru semester lima yang menjadi subjek dalam penelitian ini harus memiliki definisi dan aksioma untuk melakukan proses analisis pendahuluan terhadap teorema-teorema untuk dibuktikan. Kesulitan mahasiswa dalam menyusun bukti pada materi Struktur Aljabar adalah menelaah pembuktian, dan melihat hubungan antara definisi dan teorema yang ada. Solusi yang diberikan berdasarkan karakteristik masalah dalam struktur aljabar adalah dengan menggunakan strategi flow proof dalam penyusunan analisis pendahuluan. Dengan menggunakan desain Quasy Experiment type One group pretest-postest design, hasil penelitian menunjukkan bahwa terdapat pengaruh strategi flow proof terhadap kemampuan analisis pendahuluan mahasiswa calon guru.

The Indonesian government makes efforts to improve students' higher-order thinking skills by implementing a Minimum Competency Assessment or Assessment Kompetensi Minimum (AKM) as a substitute for the National Examination. With the implementation of the AKM, it is necessary to find out how students can solve these questions. This research analyzed students' higher-order thinking skills in solving AKM-type math problems. The research method used is descriptive qualitative research consisting of 3 stages: the preparation stage, the implementation stage, and the data analysis stage. The research was conducted in the odd semester of the 2020/2021 academic year with the research subjects of eleven 8th grade students of SMP IT Raudhatul Ulum Sakatiga, South Sumatra, and SMPN 11 Banjarbaru, South Kalimantan. Data collection techniques used are tests, documentation, observation, and interviews. The data were analyzed qualitatively. The results showed that students with high abilities could solve several questions that required analytical power but were still weak in solving questions that required evaluation. Other students still need to improve their analytical and evaluation skills.

This study aimed to develop an interactive e-module based on the RME approach, focusing on parallel lines and angles. The e-module was designed using a development studies approach with two main stages: preliminary and formative evaluation. These included self-evaluation, expert review, one-to-one trials, small group trials, and field tests. Data were collected through validation sheets, student response questionnaires, pretests, and posttests. The e-module was deemed valid and practical, with average validation scores from experts and students of 4.4 and 4.89, respectively. Furthermore, the effectiveness of the e-module was measured using T-Test and N-Gain analysis, which showed a significant improvement of 38% in students' mathematical reasoning skills. The findings demonstrate that the RME-based interactive e-module is an effective teaching tool for enhancing mathematical reasoning skills, particularly on parallel lines and angles. This e-module provides an alternative solution for teachers to facilitate interactive, context-based, and independent learning, aligning with the demands of 21st-century education. Future research could explore integrating virtual laboratories or GeoGebra software into the e-module and applying it to other mathematical topics, such as angles in polygons

This research explores the contributions of Girard Desargues, a pivotal but often overlooked mathematician in geometry. The study aims to provide insights, inspire interest, and evaluate the understanding of prospective mathematics teachers regarding Desargues' contributions, particularly his work on projective geometry. Employing a qualitative approach, the research integrates a literature review and a case study. Literature data were sourced from academic journals and books, while the case study involved interviews with students from five mathematics education classes. Open-ended interviews assessed students' familiarity with Desargues and their ability to comprehend and apply his theorem. Data were analyzed through meta-analysis and thematic analysis. The findings categorize student responses into three levels: Medium of Desargues and Desargues Theorem, Intermediate Knowledge of Desargues and Desargues Theorem, and Low of Desargues and Desargues Theorem. The results underscore varying levels of awareness among future mathematics educators and suggest that integrating historical mathematical insights into education may support a deeper understanding of concepts.

Reasoning and proof is the ability to arrange patterns, make conjectures, test conjectures, and carry out logical proof, which can be seen as negative or positive for students when solving proof problems requiring reasoning skills. Prospective mathematics teachers in the Mathematics Education Study Program of FKIP Universitas Sriwijaya became the subject of this study. As the research instrument, the questionnaire was designed to explore students' opinions and responses to problems with significant logical difficulty. Sentiment analysis was used to analyze the opinions of prospective mathematics teachers on reasoning and proof questions by grouping positive and negative opinions. The technique used in this study uses the Naïve Bayes algorithm. The classification results in this study were 58.2% positive and 41.86.7% negative, with a total of 70 data. The final result achieved an accuracy value of 53.33%, signifying the reliability of the Naïve Bayes algorithm in understanding and classifying the complex spectrum of sentiments expressed by students. The implications of these findings go beyond sentiment analysis, providing valuable insights for educators, curriculum developers, and policymakers in designing learning strategies and educational policies that can improve mathematics students' reasoning and proof abilities.
