The study identified research trends in higher-order thinking skills in Mathematics Education in Indonesia, from Design to Data Analysis. The data came from content analysis of math education articles. As of April 2022, mathematics education articles in the Science and Technology Index (SINTA) are used solely. The Indonesian Ministry of Research, Technology, and Higher Education founded SINTA (http://sinta2.ristekdikti.go.id) to evaluate science and technology. This research shows that qualitative methods, such as theme analysis or grounded theory, can provide insight into student learning, while quantitative methods, such as regression or multivariate analysis, provide statistical analysis of HOTS factors. Recommendations include improving teaching, research, and policymaking on choosing the correct analysis method and institutional support. Diversification and data analysis are essential to improve HOTS research and support Indonesian education development.

This study aims to examine the relationship between information literacy, optimized learning spaces, and TPACK Skills on the mathematical digital literacy skills of prospective mathematics teachers. The method is non-experimental research with a causal correlation design and a quantitative approach using the Structural Equation Modeling (SEM) analysis method. The population in this study were undergraduate mathematics teacher candidates. The sample was obtained from as many as 216 respondents using purposive sampling from public and private universities in Riau, West Sumatra, Bengkulu, Banten, Jakarta, West Java, Yogyakarta, and East Java. The instrument used is a Likert scale on a scale of 1-5, which consists of 24 indicators representing 4 variables. Based on the results of the assumption test, validity test, and model fit test, it can be concluded that the SEM model in this study is suitable and feasible and can describe the theory and findings in the field. Based on the inner model test, it can be concluded that information literacy (LT), Optimize Learning Spaces (LS), and TPACK Skills (TK) have significant effects on mathematical digital literacy (DL) in terms of estimates and P <0.05. The results of this research indicate that the increasing need for the application of learning technology, especially in mathematics learning, requires increasing the competence of teachers and students in integrating technology in mathematics learning and digital mathematics literacy needs to be the focus of further research.

This research represents a significant step in exploring the potential of Augmented Reality (AR) in the context of geometry learning. By utilizing the Scopus database, this research explores AR-related trends and content in geometry learning. The literature review method was used, with a bibliometric analysis approach and systematic literature review, which included four stages: identification, screening, eligibility, and inclusion, resulting in 31 final data. This is not just a description of the data but rather an attempt to present a deeper understanding of the role and potential of AR in enhancing geometry learning. In the ever-evolving world of education, a better understanding of the role of technology such as AR can open the door to more innovative and effective learning approaches. Research shows that AR technology can improve students' understanding of geometry concepts, increase learning motivation, and improve teachers' teaching skills. With AR applications, learning geometry becomes more interactive, visual, and engaging for students at various levels of education. In addition, the use of AR technology can also help create a more in-depth learning experience and motivate students to be more active in the learning process.

Indonesian students perform inadequately in the International Mathematics and Science Study (TIMSS). Before utilising National Examination (UN) questions as measures of learning accomplishment, evaluating them within the context of a theoretical framework for mathematics education is imperative. They analyse student mathematical proficiency using TIMSS and National Examination questions and apply pedagogic anthropological theory, particularly praxeology. This study employed content analysis as a qualitative research method. An algebraic analysis was conducted using the praxeological technique. This entails evaluating concerns, approaches, and technological and theoretical alternatives (logo block). The results indicate that the TIMSS questions require careful consideration and analytical thinking. In contrast, National Examination questions restrict students' cognitive capacities to acquire knowledge on specific topics. The placement of national test question types will be determined based on analytical data. Indonesian students must enhance their arithmetic scores, which consistently remain low. To promote the growth of a highly skilled labour market, the government must comprehend the intricacies involved. Teachers should customise their classes to align with the individual learning objectives of each student.

Maths is one of the most challenging courses for many pupils. Maths is often the most complex subject for many students. Newman's Error Analysis analyses eighth-graders math problems. Assessing higher-order cognitive ability is the primary purpose. This qualitative study was conducted in a Majalengka, West Java, junior high. Five randomly selected kids with different math skills participated. Following up with interviews and testing Bloom's taxonomy's latest HOTS signal questions were the critical data collection approaches. These questions test analytical (C4), evaluative (C5), and creative (C6) skills. Students had to model, sketch, confirm geometric calculations, and calculate dimensions using available components. Newman's Error Analysis was applied to analyse typical misunderstandings and errors. This exercise showed students' geometric reasoning and problem-solving weaknesses. The findings suggest customised teaching methods to improve students' geometric knowledge and performance. Reducing data, presenting facts, and concluding helped us comprehend pupils' cognitive processes and geometric challenges.

Students' mathematical reasoning abilities can develop depending on the teacher's involvement in the classroom. The problem that often occurs in the class is that the teacher's actions have not been neatly arranged to encourage students' mathematical reasoning in learning mathematics. This article aims to observe the actions taken by a group of mathematics teachers in encouraging students' mathematical reasoning abilities. This type of research is qualitative research with data collected from learning recordings in the classroom. The research subjects were three junior high school, mathematics teachers. The teacher observed how students reasoned during 12 sessions as they studied and completed homework. The results of observing students' mathematical reasoning activities, such as building reasonable arguments and drawing correct conclusions, were concluded to enable teachers to test their students' mathematical reasoning. The findings of this study indicate that teachers can foster students' mathematical reasoning by applying the following strategies: (a) providing appropriate learning interventions; (b) assigning open tasks without solution methods, and (c) fostering a learning community that values reasoning and the construction of shared ideas.

Prospective mathematics teachers must have the characteristics of mathematical science, namely systematic, logical, and critical. This study aims to reveal the analysis of learning obstacles experienced by prospective mathematics teachers in number theory lectures with sub-material of division relations, FPB and KPK. This research uses a qualitative approach method in descriptive form. This research was conducted by collecting data through questionnaires and interviews and validated using the triangulation method. The study was limited to the analysis of ontogenic learning obstacles according to Brosseasu. The results of this study were that 4 out of 6 research subjects experienced the occurrence of ontogenic learning obstacles with details of 37.5% of prospective teacher students experiencing psychological ontogenic obstacles and instrumental ontogenic obstacles, then 25% experiencing didactic ontogenic obstacles. This indicates that students' readiness to take part in number theory courses is still weak. Students are weak in terms of psychological readiness, weak in readiness for complete mastery of related material previously studied and weak in terms of following the thought process needed in this course.

This study aims to analyze the pedagogical competence of mathematics teachers and students' numeracy level in solving numeracy problems. The research was conducted in one junior high school in Bandung using a qualitative approach and case study design. The subjects of this research were 16 students in grade VIII and one math teacher at a junior high school in Bandung. Data were collected through observation, numeracy tests, and interviews. The numeracy test results showed that four students had a low numeracy level, six were medium, and six were high, with an average numeracy score of 70.625, which was in the medium category based on the indicator scale. Observations and interviews revealed that teachers have good pedagogical competence. Teachers can design learning according to the curriculum, use methods that actively involve students, and provide constructive feedback. However, test results show variations in students' numeracy levels that require adaptive learning strategies significantly to help students with low numeracy. This research emphasizes the importance of problem-based and differentiated learning approaches to improve students' overall numeracy ability. In addition, further evaluation of other factors, such as motivation and learning environment, which may affect students' numeracy ability, is needed.
