Mathematical representation is essential as the gateway to mastering mathematical literacy. This literature study aims to determine the growth of students' mathematical representation abilities in the last three years. This literature study presents a literature review on the development of mathematical representations, including media, strategies, and measurement instruments to serve as the basis for future mathematical representations. The literature study method used is the SLR (Systematic Literature Review), utilizing a review procedure that refers to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework in the period 2020 to 2022 because the growth in literature studies on mathematical representations is very significant and latest. Data were collected by reviewing 24 Scopus-indexed articles and proceedings from the Scopus database. The study's results reveal that from the 24 selected literature, it can be interpreted if the mathematical representation ability can be improved and fulfills the indicators of mathematical representation itself by providing innovation in media, strategies, and instruments in learning mathematics. The innovations provided can be in the form of technology integration (Geogebra), no longer conventional strategies (RME strategy), and instrument indicators of the representation itself. Thus the ability of students' mathematical representations is no longer included in the low category in solving mathematical problems.

This study aims to evaluate the effectiveness of FlipaClip as a learning media, and to compare the problem-solving abilities of students who learn using FlipaClip and PowerPoint. This study employed the ADDIE development paradigm (Analysis, Design, Development, Implementation, and Evaluate) as a framework for research and development (R&D). The findings demonstrated the validity and viability of learning media that use a contextual approach to linear program content. With extremely valid criteria, the material validation findings came out at 84.38%. The validation results from media experts were 94.79%, which is considered highly valid. Although the student response received an assessment percentage of 83.64%, the response also met the FlipaClip-based learning media's "very interesting" requirements, indicating that it is practical to use. Moreover, the research shows that FlipaClip-based learning media on program material can improve the mathematical problem-solving ability of class XI students. Quantitatively, the difference is shown by the interpretation of N-Gain obtained in the experimental class, which is quite an effective category with a percentage of 70.22%. The average mathematical problem-solving ability of grade XI students who are given FlipaClip-based learning media is higher than the average student who is not given the media, as indicated by the results of the independent sample t-test, namely the Sig. (2- tailed) value of 0.000 <0.05.

Mathematical representation ability is an essential skill for students to understand mathematical concepts. Many studies have been conducted regarding this ability, but it is necessary to map existing research to provide a clearer picture of future research topics. This study aims to provide a bibliometric review of trends using mathematical representation skills in mathematics teaching research. The method in this study is bibliometric analysis, which aims to analyze and classify bibliographic material by presenting representative summaries of the literature in the Scopus database. The search was carried out using the keyword "mathematical representation" and selecting "article title" in the search menu in the Scopus.com database. Perish or Publish (PoP) software analyzes the author's name, number of document citations, document title, year of publication, document source, publisher, and document type. The results showed 99 publications and 357 citations related to mathematical representations, where the number of publications and citations fluctuated. The application of learning models and approaches, computer media, and analysis of mathematical representations is a research trend related to this variable. Therefore, paying attention to mathematical representations in learning mathematics and using effective strategies to improve students' mathematical representation abilities is essential. The findings of this study indicate the need to develop syntax and learning media based on mathematical representations to strengthen students' mathematical abilities.

Computational Thinking (CT) is essential for 21st-century problem-solving but remains underdeveloped in abstract mathematics courses like linear algebra. This study addresses the gap by integrating APOS theory, Realistic Mathematics Education (RME), and digital tools into a strategic learning model to enhance CT and conceptual understanding. A Design-Based Research (DBR) approach was employed to develop, implement, and evaluate the model with 73 first-year university students enrolled in a linear algebra course at Institut Bakti Nusantara. Participants were grouped by class section into experimental (APOS–RME–digital integration) and comparison (conventional digital instruction) groups. Data were collected through pre-post CT assessments, classroom observations, surveys, and learning analytics. Students in the experimental group showed significantly higher gains across five CT components—abstraction, decomposition, algorithmic design, evaluation, and generalization—compared to the control group, with medium to large effect sizes. Improved conceptual understanding of vectors and linear transformations was also observed. Learners reported high usability and perceived instructional value, particularly in contextual and interactive tasks. Implementation challenges related to digital access and skills were mitigated through structured onboarding and offline resources. The findings demonstrate that a well-integrated APOS–RME digital model can systematically develop CT and mathematical understanding. High engagement and usability support its practical viability in higher education settings. This model offers a scalable, theory-informed framework for digital mathematics instruction. Future research should explore long-term impacts, equity strategies, and cross-institutional adoption to further enhance its applicability and sustainability.
