Abstract

In addition to the theory and implementation, the description of research trends and the direction of development of mathematical mindset research still needs to be explored. The study aims to find trends and mapping from the mathematical mindset research development. The method used is bibliometric with the help of MS Excel and VosViewer. The metadata is 995 articles indexed by Google Scholar from 2019 to 2025, obtained from Publish or Perish by entering the keyword "mathematical mindset." The results show a sharp decline in post-2020 publications, the most in 2020, as many as 272, but plummeting to 3 in early 2025. This decline occurred due to policy changes after the pandemic, reallocating funding to digital learning, and competition for research priorities. Boaler's book related to Mathematical Mindset 2022 became the publication with the most citations (2329). The VOSviewer analysis results identified four main clusters, with the mathematical mindset being in cluster three. In addition, it found the potential for a weak connection with technological terms, which could be a new research direction. The results of this study provide optimism and opportunities for mathematical mindset research to be more associated with other terms that can be connected, especially in mathematics education research.

Abstract

This research is classified as descriptive qualitative research. The type of research is a case study. The subjects in this study were three students in the Geometry of Plane and Space course. The research instrument used was a question related to the concept of similarity, along with Newman's error analysis sheet, to identify the type of error. The data analysis technique used was to identify and classify errors in students' answers related to questions on the concept of similarity. According to Newman, the answers were further analyzed to describe the types of errors that arise from each category and formulate alternative solutions that can be done to overcome the various types of errors. Based on Newman Error Analysis, the types of errors experienced by students include Comprehension Errors, Transformation Errors, and Process Skills Errors. These types of errors are related to students' lack of understanding regarding the requirements for two triangles to be said to be similar; students are less skilled when carrying out the proof process, which requires supporting information when stating a statement in the proof process, and students' lack of mastery in using the Pythagorean Theorem. Alternative solutions include emphasizing several key aspects related to the concept of similarity, both in terms of the conditions for two triangles to be considered similar and the application of the similarity theorem. It requires considerable practice in constructing mathematical proofs and utilizing the Pythagorean Theorem. Recommendations for subsequent researchers include exploring the types of errors in the concept of similarity in more varied contexts.

Abstract

This study aims to analyze the perspectives of junior high school mathematics teachers in Bogor Regency regarding the implementation of the STEM Challenge as an alternative assessment in mathematics learning. This research uses a qualitative approach with a phenomenological method. Data were collected through open-ended questionnaires, in-depth interviews, and document studies. The results of the study reveal three findings: (1) teachers assess that the STEM Challenge is quite appropriate and has the potential to assess students' abilities, especially related to 21st century skills such as critical thinking, creativity, communication, and collaboration; (2) many teachers realize that conventional assessments (written tests) have limitations as they tend to focus only on cognitive aspects; and the last, (3), although the STEM Challenge is considered a good alternative assessment, teachers also expressed Challenges and obstacles in its implementation, including limitations in infrastructure, lack of learning time, and the need for adaptation for teachers and students. This research recommends the need for policy support, teacher training, and the provision of resources so that the STEM Challenge can be effectively implemented in order to make assessments in mathematics learning more contextual and meaningful.

Abstract

Over the last ten years, many studies have discussed the effect of implementing the Realistic Mathematics Education (RME) and Contextual Teaching and Learning (CTL) approaches on students' mathematical communication ability. However, these studies show inconsistent results. This study aims to analyze the effect of implementing the RME learning approach, the effect of implementing the CTL approach, and the difference in the effect of implementing the RME learning approach compared to the CTL approach on students' mathematical communication ability. This research used a quantitative approach with a meta-analysis method. The search for research articles with publication years from 2012 to 2022 was carried out using several databases, namely DOAJ, ERIC, Google Scholar, IOP Publishing, Garuda Portal, Semantic Scholar, and national journals link. Using the PRISMA protocol, the authors obtained 15 research articles on RME and 14 research articles on CTL that met the inclusion criteria and could be used in this study. The results of this study showed that the implementation of the RME learning approach has a moderate influence (g = 0,820) on students' mathematical communication ability, and the implementation of the CTL approach has a strong influence (g = 1,017) on students' mathematical communication ability. There is no significant difference between the effect of the RME learning approach's implementation and the CTL approach's effect on students' mathematical communication ability (Q_value = 2,329, p_value = 0,127). Therefore, the RME and CTL learning approaches can be used as learning alternatives that aim to enhance students' mathematical communication ability.

Abstract

The study identified several learning obstacles (LO) experienced by students in Calculus I, particularly misconceptions related to algebraic concepts, graphical representations of functions, absolute values, inequalities, exponents, logarithms, and trigonometry. These obstacles negatively affect students’ conceptual readiness for learning Calculus. This study aims to develop an HLT-based pre-calculus module for 41 prospective mathematics teachers at a state university in Indonesia. The instruments included a diagnostic test, interview guidelines, and expert validation forms for the module. Data were collected through literature review, analysis of learning obstacles based on diagnostic test and interview results, and expert validation of the module. The pre-calculus module was developed using the 4D model (Define, Design, Develop, Disseminate), and the data were analyzed using a descriptive qualitative approach. Expert validation results indicated that the module’s content, language, and presentation achieved validity scores above 80% across all aspects. Considering the effectiveness of the HLT framework, the module is expected to support scaffolding, reduce misconceptions, and map students’ conceptual thinking trajectories. Furthermore, it is expected to serve as an independent learning resource that supports a logical transition from algebraic prerequisites to Calculus I concepts.
