Differentiated learning is a learning approach that adapts to the individual needs of students, both student readiness, interests, and their learning profile. Although this concept has been widely discussed, its implementation in mathematics learning still encounters many obstacles. This study aims to describe the conception of mathematics teachers towards differentiated learning and its implementation in supporting the Independent Curriculum. This research is qualitative research using questionnaires as a data collection method. The subjects of this study were 27 junior high school mathematics teachers in the city of Surakarta. Data is analyzed using qualitative analysis techniques including data reduction, data presentation, and verification/conclusions. The results showed that teachers' understanding of differentiated learning was good, both in theoretical concepts and implementation. However, teachers still face obstacles in design, limited learning time, classroom management, and limited knowledge on some aspects of differentiated learning. The study concluded that even though teachers already understand the concept of differentiated learning, they need further support to overcome existing barriers. The implications of this research point to the need for additional training and resources to support more effective implementation.

Indefinite integrals are a fundamental concept in calculus. This qualitative study aims to describe the content of school mathematics textbooks on indefinite integrals. The analysis used the concept of praxeology, which includes theory, technology, and techniques, based on the Reference Epistemological Model. The primary instrument in this research was the researcher, who used data from school mathematics textbooks, including two electronic textbooks used in Indonesia, one textbook from Singapore, and one from the Cambridge curriculum. The study results included a Reference Epistemological Model for indefinite integrals, used to compare textbook content and praxeological components. Praxeological analysis shows that the theoretical and technological components of Indonesian school mathematics textbooks are more complex than those from Singapore and the Cambridge curriculum. These differences are attributed to variations in the mathematics curricula of the three regions. Therefore, the Reference Epistemological Model can guide the development of instructional materials on indefinite integrals, taking into account the complexity differences among the textbooks. Materi integral adalah salah satu konsep fundamental dalam kalkulus. Penelitian ini merupakan penelitian kualitatif yang bertujuan untuk mendeskripsikan muatan pada buku teks matematika sekolah pada materi integral tak tentu. Analisis menggunakan konsep prakseologi yang meliputi teori, teknologi, dan teknik berdasarkan Referensi Model Epistemologi. Instrumen utama dalam penelitian ini adalah peneliti sendiri dengan menggunakan sumber data berupa buku teks matematika sekolah yaitu dua buku sekolah elektronik yang digunakan di Indonesia, satu buku teks matematika yang digunakan di Singapura, dan satu buku teks kurikulum Cambridge. Hasil penelitian berupa Referensi Model Epistemologi pada materi integral tak tentu yang digunakan untuk perbandingan buku dan organisasi prakseologi. Analisis prakseologi menunjukkan bahwa komponen teori, teknologi, dan teknik pada buku teks matematika sekolah dari Indonesia lebih kompleks dibandingkan dengan buku dari Singapura dan kurikulum Cambridge. Adanya perbedaan tersebut didasarkan pada muatan kurikulum yang berbeda diantara ketiganya. Dengan demikian, Referensi Model Epistemologi yang dihasilkan dapat dijadikan salah satu acuan dalam mengembangkan pembelajaran pada materi integral tak tentu, termasuk perbedaan kompleksitas antar kedua buku dapat menjadi referensi untuk digunakan sebagai sumber pembelajaran.

The concept of exponentials and logarithms is one of the essential concepts in mathematics as part of transcendent functions. However, students' understanding of these two concepts has yet to be fully mastered, so there are still errors in solving problems related to these two concepts. This study aims to describe the meaning and meaning process and explore the potential learning obstacles of students based on the meaning and experience of students in obtaining the meaning of exponents and logarithms in senior high school. This qualitative study uses a hermeneutic phenomenological approach with student participants and high school mathematics teachers. Data was collected using tests, documentation, and interviews with students and teachers. Data were analyzed qualitatively to identify learning obstacles and the meaning of exponentials and logarithms. The results showed the meaning of exponents and logarithms according to students, namely exponents as power numbers and logarithms as the opposite of power numbers. In addition, the results also show the existence of learning obstacles in students, both ontogenic, epistemological, and didactic. Based on the findings, these learning obstacles can be considered when developing an appropriate didactic design.

Indonesia's participation in PISA is less satisfactory, particularly in mathematics. Uncertainty and data are two of the PISA content areas being evaluated. Therefore the aim of this study is to analyze students' abilities to solve mathematical problems such as PISA on uncertainty and data content to map student readiness for PISA. This study is kind of qualitative study used a case study design. The sample in this study was 84 students of grade IX junior high school who were selected with a simple random sampling technique. The data collection method employs both test and non-test instruments. The data analysis technique used in this study consist of data reduction, data presentation, and conclusion and verification. The results showed that 689 students scored out of 1344, representing 51.41%. These results show that students' ability to solve math problems such as PISA on uncertainty and data content is in the moderate category. While each material, namely statistics and opportunities, is in the high and low categories. This condition is based on learning that has yet to lead students to contextual problems. With these results, it is hoped that there will be efforts to improve the learning process by involving problems such as PISA as habituation.

Artificial intelligence (AI) is increasingly being integrated into education, offering new opportunities for enhancing learning, especially in challenging subjects like mathematics. However, there is limited research on how students perceive and accept AI in mathematics education, particularly in the context of Indonesian higher education. This study aims to explore mathematics education students’ acceptance and perceptions of AI tools in enhancing their learning experience. Using a sequential explanatory mixed-methods design, the study employed a Technology Acceptance Model (TAM) questionnaire for quantitative data and in-depth semi-structured interviews to gather qualitative insights. The participants were 389 mathematic students from several universities in Surakarta municipality, Indonesia based on non-probability sampling technique through sampling quota. The results show that students generally perceive AI as useful and easy to use, with high scores for Perceived Usefulness (PU) and Perceived Ease of Use (PEU). AI was appreciated for its ability to provide personalized learning, immediate feedback, and flexibility. However, students' Behavioral Intention to Use (BIU) AI was lower, indicating hesitation toward integrating AI regularly into their learning routines. The findings highlight that while AI has the potential to enhance learning, students still value traditional face-to-face interactions with instructors and are concerned about over-reliance on technology. The study contributes to theoretical framework that AI tools should complement, not replace, traditional teaching methods. Practically, the integration of AI in education should be gradual, with adequate support for both students and instructors. Future research should explore long-term adoption and investigate the role of educational policies in supporting AI integration.

Mathematical abstraction as part of mathematical thinking process is an important and fundamental process in mathematics and its learning. Pre-service mathematics teachers' experiences and sentiments towards mathematical abstraction can contribute to the way they teach in the future. This study involved 67 Pre-service Mathematics Teachers at one of the Universities in Central Java Province who aimed to analyze their sentiments towards mathematical abstraction problems. The data collection technique used a questionnaire to reveal the Pre-service Mathematics Teacher's response to abstraction problems. Sentiment analysis is used to analyze the responses given which are categorized into positive, negative, or neutral. The technique used in the research is Naïve Bayes Classifier Multinomial. The classification results show 62.9% negative sentiment, 24.2% neutral sentiment, and 12.9% positive sentiment. In addition, the model evaluation results show an accuracy value of 66.7% which indicates the reliability of the model in classifying the sentiments expressed by Pre-service Mathematics Teachers towards mathematical abstraction problems. Pre-service Mathematics Teacher sentiment towards mathematical abstraction problems is dominated by negative sentiment. This shows that the process of mathematical abstraction is still considered a complicated and confusing process.
