Abstract Learning mathematics in three-dimensional material often experiences difficulties, one of the factors causing this is the low level of student independence in learning. One of the alternatives provided to solve this problem is by determining innovative learning strategies. One of the innovative learning methods that will be used as an alternative to overcome this problem is the SAVI learning model based on discovery strategies, which is defined as a teaching technique that involves all students' senses in searching for and discovering a mathematical concept. This learning activity focuses students on the process of discovering a mathematical concept. The aim of this research is to analyze the results of the process that has an impact on the formation of students' independent character in learning three-dimensional mathematics material using the SAVI model approach based on discovery strategy. The research subjects were taken from 6 students who had different abilities (heterogeneous), namely by grouping the upper (high ability), middle (medium group), and lower (lower group). Data collection techniques are obtained by observation, interviews, documentation. The instruments used were observation sheets and interview guidelines, documentation. Meanwhile, data processing techniques use gain and triangulation tests. The results of observations of independence in this study showed that the average increase in the character of independence from meetings I to V in the selected subjects was 78.40, meaning an increase in the formation of good criteria.

Abstract

This study aims to analyze students' mathematical literacy skills in relation to their learning styles (visual, auditory, and kinesthetic) and their school learning environment. A mixed-methods approach was employed, using mathematical literacy tests, student response analysis, and in-depth interviews. The results show that visual learners excel in numerical representation and written communication but struggle with formal symbolism without visual support. Auditory learners understand procedures well through verbal explanations but have difficulty constructing arguments and alternative strategies. Kinesthetic learners perform well on contextual problems through practical activities but are weak in visual representation and formal reasoning. A non-varied and unresponsive learning environment hampers the development of mathematical literacy. These findings emphasize that a mismatch between learning styles and instructional approaches negatively affects literacy achievement, particularly in reasoning, argumentation, and representation. Therefore, fostering a learning environment that accommodates diverse learning styles is essential for enhancing students’ overall mathematical literacy.

Abstract

The increasing urgency to address climate change has positioned Sustainable Development Goal 13 (Climate Action) as a priority for governments and businesses worldwide. Technological innovations such as Artificial Intelligence (AI), the Internet of Things (IoT), and Blockchain have emerged as transformative tools for reducing environmental impacts, improving energy efficiency, and promoting ethical and sustainable business practices. However, the extent to which these technologies contribute to climate action remains underexplored. This study aims to investigate the role of AI, IoT, and Blockchain in helping businesses achieve SDG 13 by optimizing resources, reducing waste, and enhancing supply chain transparency. A mixed-methods approach was adopted, combining qualitative and quantitative techniques. Semi-structured interviews were conducted with key stakeholders from businesses implementing these technologies, while a survey of 150 businesses was administered to capture broader adoption patterns. The data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to test the proposed hypotheses. The findings reveal that AI and IoT have significant positive effects on energy management and sustainability outcomes, while Blockchain plays a supportive role by improving transparency and ethical practices, though its adoption remains limited. The combined integration of these technologies yields the most substantial impact. This study concludes that businesses should adopt a holistic strategy to fully leverage technological innovations for advancing SDG 13 and combating climate change.

Abstract

Creative thinking is a key objective in geometry learning, yet prior studies have focused more on instructional interventions than on students’ initial profiles. This study aims to map students’ creative thinking in geometry and examine its variation across cognitive styles. A descriptive survey with comparative analysis was conducted involving 62 undergraduate students at UIN Siber Syekh Nurjati Cirebon. Creative thinking was measured using the Creative Thinking in Geometry Test (CTGT), covering fluency, flexibility, originality, and elaboration, while cognitive styles were classified into Field Independent (FI) and Field Dependent (FD). Data were analyzed using descriptive statistics and independent samples t-tests. The results indicate uneven performance across the dimensions, with fluency the highest and originality the lowest. Most students demonstrated moderate levels of creative thinking. FI students performed significantly better in fluency, flexibility, and originality than FD students, while no significant difference was found in elaboration. These findings suggest that cognitive style influences students’ engagement with geometry tasks and highlight the importance of identifying students’ initial profiles to inform instructional design.
