Statistical literacy is an essential skill for prospective teachers, as it equips them to become effective educators in an increasingly complex and multicultural society. However, many prospective teachers currently exhibit insufficient proficiency in this area. To address this issue, it is imperative to develop educational programs that prioritize statistical literacy to prepare students to be informed global citizens. This study explores the integration of South Sumatra's local wisdom into statistical literacy education, providing a culturally relevant context for enhancing these skills. The research employs a descriptive qualitative approach consisting of four key stages: problem identification, inductive theorizing, hypothesis testing through observational data, and the processes of replication and refinement. Data collection methods included interviews and observations, which were analyzed qualitatively using triangulation techniques. The findings suggest that incorporating South Sumatra's local wisdom into statistical literacy education is feasible, provided the context meets specific criteria, such as it is rooted in the local wisdom of South Sumatra, it is meaningful and relevant to students, it holds significance for the student's learning experience, it actively engages students in classroom activities, it fosters students' abilities to articulate opinions on civic statistics and their social implications, and it involves statistical scenarios that can be effectively integrated into educational activities. This exploratory study contributes to the theoretical development of statistical literacy education by integrating local wisdom, specifically from South Sumatra, and by introducing these cultural elements to both national and international audiences.

Computational Thinking (CT) has emerged as a fundamental skill in mathematical problem-solving, fostering logical reasoning and structured approaches to tackling complex problems. Despite its significance, the integration of CT in mathematics education, particularly in secondary school curricula, remains insufficiently explored, leading to a gap in understanding students' proficiency in CT skills. This study aims to investigate the CT abilities of seventh-grade students in solving social arithmetic problems based on four key CT indicators: decomposition, pattern recognition, abstraction, and algorithmic thinking. Data were collected through a set of problem-solving tasks designed to assess each indicator comprehensively. The findings reveal that 25% of students demonstrate high CT proficiency (score >78.12), 52% exhibit medium proficiency (score between 17.78 and 78.12), and 23% fall into the low category (score <17.78). The mean scores for each CT indicator are as follows: decomposition (53), pattern recognition (46), abstraction (40), and algorithmic thinking (53), with abstraction emerging as the weakest area. These results indicate that the majority of students possess only a moderate level of CT competence, particularly struggling with abstraction, which involves identifying critical information and disregarding extraneous details. The study underscores the necessity of developing instructional strategies that enhance students' CT skills, particularly in pattern recognition and abstraction, to foster deeper mathematical understanding and problem-solving capabilities. The findings contribute

Mathematical literacy stands as a critical skill imperative for navigating the complexities of the 21st century. Enhancing students' mathematical literacy necessitates comprehensive engagement across the educational landscape. This aligns with the Guru Penggerak (GP) initiative, established by the government to serve as educational leaders, propelling the entire educational system forward. Nonetheless, the current GP program needs more specific provisions addressing mathematical literacy, and the existing learning environments for mathematical literacy remain constrained. Consequently, there is a pressing need to develop a dedicated mathematical literacy learning environment within the GP framework. This study endeavors to create a mathematically literate learning environment that is both valid and practical, potentially impacting the GP program significantly. Employing a design research approach, the study progresses through three key stages: preliminary, prototyping, and assessment. Seven teachers participated as subjects, using data collection methodologies including walkthroughs, observations, questionnaires, and interviews, which were analyzed descriptively. Findings indicate the development of a model for a mathematical literacy learning environment termed D-C-C with the LEPscO framework, which is deemed valid due to its alignment with the PISA framework, Indonesian educational curriculum, and unambiguous language. Moreover, the model proves practical for implementation within the GP program, exhibiting potential effects such as enhanced teacher satisfaction, learning, organizational support, and utilization of new knowledge, alongside improved student outcomes reflecting heightened mathematical literacy proficiency. This research contributes to educational discourse by introducing the LEPscO Framework, encompassing a Digital-Class-Community learning environment, structured learning processes encompassing training, classroom implementation, knowledge sharing, and community development, and targeted learning outcomes focusing on teachers' comprehension and reinforcement of mathematical literacy in education.

Mathematical thinking involves how individuals present, understand, and critically examine mathematical truths, considering how their relation to representation or imagination. However, students often exhibit low mathematical thinking skills. Previous research shows that digital worksheets based on creative problem-solving can foster these skills, yet the relationship between mathematical thinking and learning styles remains unexplored. This study aims to develop innovative digital worksheets based on creative problem solving, categorized as valid, practical, and effective in enhancing students' mathematical thinking with audio-visual learning styles. The study employs a development method comprising two main stages: a preliminary study (analysis and design) and a formative study (evaluation and revision). Data collection instruments include tests, observations, validation sheets, questionnaires, and interviews. The analysis integrates both quantitative and qualitative approaches. The study involved 15 audio-visual learners from 24 eighth-grade students at SMP Srijaya Negara Palembang. The results indicate that students excel in specializing and identifying problems based on given information. Their generalizing skills, including finding patterns and relationships are strong. However, their conjecturing and convincing skills require improvement, particularly in making connections and reasoning. The digital worksheets were deemed 93% valid and practical, significantly enhancing students' mathematical thinking, particularly for those with an audio-visual learning style. While students demonstrated excellent skills in specialization and good skills in generalization, there is still a need for improvement in conjecturing and convincing due to errors in mathematical reasoning.
