Abstract

This study aims to show an increase in students’ chemical representation ability through the integration of Problem-Based Learning (PBL) assisted by Nearpod on electrolysis cell material and describe student activities and their ability to complete worksheets. This study used a pre-experimental method with a one group pretest-posttest design and involved second-semester students in the basic Chemistry 2 courses. The results showed that the improvement in chemical representation ability was in the medium category (N-Gain: 0.68), learning activities were carried out very good (88.86%), and the student’s ability to complete worksheets was also classified as high (average score: 89.52). These findings indicate that integrating PBL assisted by Nearpod is an effective, innovative approach to improving students’ chemical representation ability, particularly in abstract electrolysis cell material, by encouraging active participation and conceptual understanding.

Abstract

This study aims to develop and evaluate the validity and practicality of a mathematics learning application called Dunia Geometri as an interactive learning medium for junior high school students. The research background is rooted in students’ low understanding and motivation in learning three-dimensional geometry, which is further exacerbated by the limited availability of innovative and interactive learning media. To address this issue, the Dunia Geometri application was designed to integrate 3D visualizations, instructional videos, and tiered evaluation features that support student engagement and conceptual understanding. The research employed a Research and Development (R&D) approach using the ADDIE model, limited to the stages of Analysis, Design, and Development. Data were collected using validation sheets completed by media and material experts, as well as practicality questionnaires administered to teachers and students. The results of expert validation indicated a high validity score (87.69%), categorized as very valid. Similarly, the practicality test showed high ratings from teachers (85.71%) and students (79.33%), demonstrating that the application is easy to use and effectively supports classroom learning activities. The implementation of interactive technology in the Dunia Geometri application has been shown to enhance students’ motivation and understanding of geometric concepts. These findings confirm that the application exhibits a high level of validity and practicality, making it an effective learning medium for teaching geometry at the junior high school level. Future development is recommended to incorporate gamification and augmented reality features to further enhance engagement and improve long-term learning outcomes.

Abstract

A problem in learning mathematics in the classroom is that there are no clear guidelines on when teacher assistance needs to be given, maintained, or stopped. This lack of clarity risks causing disproportionate assistance, either in the form of over-scaffolding which creates learner dependence, or under-scaffolding which inhibits concept understanding. This study aims to identify and examine in depth the threshold for providing scaffolding by teachers in mathematics learning, based on the Zone of Proximal Development (ZPD) theory. The approach used was descriptive qualitative with the subject of six students in class XI at SMK Ahmad Yani Jabung who were selected based on the category of high, medium and low academic ability. Data were obtained through observation of learning activities, in- depth interviews, and document analysis of students' work, and analyzed through the stages of data reduction, presentation, and verification using the Miles and Huberman model. The results showed that the threshold of scaffolding is contextual and dynamic, determined by three main indicators: learners' cognitive responses, the level of dependence on assistance, and verbal and nonverbal expressions. The process of providing assistance includes three stages, namely initial assessment, implementation of scaffolding, and gradual reduction of assistance. The conclusion of this study emphasizes the importance of adjusting teacher interventions according to learners' ZPD position, as well as the need for teacher training and the development of ZPD-based adaptive learning models to improve learning effectiveness and encourage learning independence.

Abstract

The importance of mathematical literacy skills in the 21st century is the main reason for conducting this research. However, students' mathematical literacy skills are not commensurate with the facts, as shown by the low PISA results in 2023, which prove that students' mathematical literacy skills are still low and cast doubt on their ability to solve mathematical problems in elementary school. The low level of students' mathematical literacy skills is due to the many mistakes made by students in solving mathematical literacy problems, necessitating a thorough analysis using Newman's method based on gender. The research method used was descriptive qualitative, with data collection techniques in the form of surveys, involving 262 students from three elementary schools in the Muara Bungo area, Jambi Province. Students were then classified according to their initial mathematical ability, which was divided into three categories: high, medium, and low. After that, six male and female students were selected for interviews. Data triangulation (Mathematical Literacy Test and Interview) ensured the validity of the data in this study. Data analysis was conducted following the steps Miles and Huberman outlined: data reduction, information presentation, and conclusion drawing. This study shows that the most common errors made by male students are reading, comprehension, and transformation, while female students more often make errors in process skills and encoding.

Abstract

Science literacy is crucial in 21st-century education but remains low among Indonesian elementary students due to ineffective teaching methods and unengaging media. This study developed and evaluated FotAR (Photosynthesis Augmented Reality), an AR-based learning media designed to enhance science literacy in elementary students. Conducted at SDN Baru 06 Pagi, East Jakarta, the research used the Borg and Gall R&D model. Data collection methods included expert assessments, the use of questionnaires, and administration of pre- and post-tests. Results showed high feasibility with scores of 97.5% from media experts and 89.5% from content experts. Student and teacher responses were also very positive, with practicality ratings of 98% and 80%, respectively. A gain score of 0.72 indicated significant improvement in learning outcomes. The findings suggest that FotAR effectively supports students' understanding of photosynthesis and improves their engagement and scientific thinking. This study concludes that AR-based learning media can be a powerful tool to enhance science literacy in elementary education.

Abstract

This study aims to examine the role of ethnomathematics integration in enhancing mathematical literacy and numeracy among elementary school students within the framework of the Merdeka Curriculum. Employing a qualitative approach through a literature review method, this article analyzes thirteen peer-reviewed research studies and scholarly publications published between 2020 and 2025 that focus on ethnomathematics, mathematical literacy, and numeracy. The findings reveal that the ethnomathematical approach—which leverages local cultural contexts as sources of mathematical learning—offers students more contextualized, meaningful, and engaging learning experiences. The application of ethnomathematics has been shown to strengthen students’ conceptual understanding, enhance numeracy competencies, and cultivate positive attitudes toward mathematics. Moreover, its integration aligns with the objectives of the Merdeka Curriculum, which emphasizes context-based learning, the inclusion of local wisdom, and differentiated instruction. The study further highlights the crucial role of teachers in designing instructional materials and strategies that meaningfully connect mathematical concepts with students’ cultural backgrounds. Accordingly, the development of ethnomathematics-based teaching resources and targeted teacher training is strongly recommended to improve the quality of elementary mathematics education in a more inclusive and transformative manner.

Abstract

This paper examines how the Sustainable Development Goals (SDGs) have been brought into university-level chemistry education worldwide. Using a blend of bibliometric and systematic review methods, we analyzed 564 publications from Scopus and Web of Science (2001–June 2025), along with a closer look at 17 influential papers. Over the past twenty years, there’s been a clear uptick in studies on this topic, largely shaped by global education policies and sustainability initiatives. The United States, Canada, China, and the UK stood out as the most active contributors. Our findings reveal that green chemistry, systems thinking, and hands-on learning are key themes. Different teaching approaches, like problem-based and authentic learning, have helped improve students’ understanding of concepts, awareness of sustainability, and ethical outlook. Still, gaps remain, especially in how these ideas play out across cultures, their long-term effects, and how fully SDGs are woven into various chemistry programs. These insights point to the important role chemistry education can play in preparing graduates who are both scientifically grounded and ethically mindful. Looking ahead, future studies might benefit from broader data, longer-term designs, and cross-disciplinary efforts to keep pushing sustainable chemistry education forward.
