Mathematical literacy relates to how people apply knowledge in real-life situations. Based on the results of PISA from 2000 to 2018, the mathematical literacy of Indonesian students is still low. The use of inappropriate teaching media is one cause of this issue, thus there is a need for technology-integrated innovation to help improve mathematical literacy. The research is experimental with a one-group pretest-posttest design. The implementation is carried out systematically by administering a pretest, then treatment, followed by a posttest. The pretest results had an average of 41.44 and the posttest results were 75.49, indicating an increase in average test scores. The pre-analysis test indicates the research instruments are feasible to use, while the paired sample t-test results show 0.000 < 0.05, indicating the VR Tour website media with an ethnomathematics approach has a significant effect on mathematical literacy. Further data analysis from the n-gain test shows 0.30 < 0.5870 < 0.70, which has medium criteria, thus indicating an increase in mathematical literacy before and after the VR Tour website media with an ethnomathematics approach. The conclusion is that the VR Tour website media with an ethnomathematics approach is effective in improving mathematical literacy.

Students' low problem-solving ability remains a problem in education. This study examines the effect of using PBL and STEM-based e-modules on mathematical problem-solving abilities in elementary to high school students focused on mathematics. The aim is to determine whether the e-modules used affect students' mathematical problem-solving abilities. The method used in this study is a system literature review (SLR) by reviewing articles from Google Scholar and Knowledge Maps sources from 2020 to 2025. The review process includes three stages: planning, implementation, and reporting. The results show that E-modules that integrate the PBL model, the STEM approach, or a combination of both are effective in improving students' ability to solve mathematical problems. These findings indicate that an innovative, student-centered learning model facilitated by e-modules is a potential strategy to address the challenges of problem-solving abilities in mathematics education.

This current research scrutinized the implementation of collaborative writing on Padlet to enhance students' coherence in writing paragraph and their engagement in the learning process. This current research employed a quasi-experimental one-group pretest-posttest design and a descriptive qualitative approach to examine students' learning processes and interactions. Twenty-five first-year college students at one of the private universities in Indonesia who joined a writing paragraphs course. Quantitative data were gathered via paragraph-writing assessments and analyzed using paired-samples t-tests, whilst qualitative data were collected through observations, questionnaires, and student reflections. According to the study, students' paragraph coherence greatly improved, with mean scores rising from 68.40 to 81.24 (p < 0.05). Additionally, throughout the six-week intervention, engagement data showed a significant shift toward more content-focused peer criticism, as well as increased participation in posting, commenting, and editing activities. The results show that lines written in groups on Padlet are easier to understand and that students are more interested in writing in English as a second language. However, since this study employed a one-group design without a control group, the findings should be interpreted cautiously. Future studies are needed to further the effectiveness of Padlet-based collaborative writing in improving students’ coherence and engagement through more rigorous experimental designs.

This study aimed to develop and evaluate the effectiveness of AVooks (Audio-Visual Books) based on the flipped classroom model in enhancing the learning independence and self-efficacy of university students with physical disabilities in the Multimedia Mathematics Learning course. AVooks is an accessibility-oriented learning medium that integrates text, audio narration, visual tutorials, and interactive navigation within a Learning Management System (LMS), enabling students to learn independently according to their individual learning pace and physical conditions. This study employed a Research and Development (R&D) approach using the ADDIE model. The participants were two university students with physical disabilities characterized by upper- and lower-limb deformities who were able to walk independently without using wheelchairs or other mobility aids. Data were collected using validated learning independence and self-efficacy questionnaires administered over seven learning sessions and analyzed using descriptive analysis, Achievement Percentage, and Normalized Gain (N-Gain). Expert validation indicated that AVooks was highly feasible for implementation, with an average score of 3.56. The results showed that the Achievement Percentage of learning independence increased from 45.00% to 91.60%, with an N-Gain score of 0.85 (high category). Likewise, the Achievement Percentage of self-efficacy increased from 41.60% to 93.40%, with an N-Gain score of 0.89 (high category). These findings indicate that integrating AVooks with the flipped classroom model provides an accessible and adaptive learning environment that effectively promotes learning independence and strengthens students' confidence in completing academic tasks. This study contributes to the advancement of inclusive higher education by demonstrating the potential of accessibility-oriented digital learning media to support university students with physical disabilities.
