Statistical literacy has emerged as a central competence in mathematics education, particularly for prospective teachers who must be able to interpret, analyze, and critically evaluate data in a world increasingly shaped by information and statistics. However, previous research shows that many prospective teachers continue to struggle with developing statistical literacy, especially in connecting abstract concepts to meaningful contexts. This gap highlights the need for instructional designs that not only strengthen statistical reasoning but also draw on culturally embedded practices to enhance relevance and engagement. Addressing this challenge, the present study develops a Local Instructional Theory (LIT) that supports prospective teachers’ statistical literacy through the integration of local cultural contexts in South Sumatra, designed within the framework of Realistic Mathematics Education (RME) as adapted in Indonesia, namely Pendidikan Matematika Realistik Indonesia (PMRI). Employing a design research methodology, the study was conducted in three phases: a preliminary investigation, a design experiment (pilot and teaching experiment), and a retrospective analysis. The resulting LIT was structured around three context-based learning trajectories, each targeting a key dimension of statistical literacy: data visualization, data interpretation, and critical evaluation. Instructional activities were grounded in authentic cultural contexts—such as Pempek demand during Ramadan, the Bekarang Iwak fishing tradition, and coffee productivity in Pagar Alam—which were used to bridge statistical concepts with learners lived experiences. Findings from the teaching experiments indicate that prospective teachers demonstrated notable shifts from procedural to conceptual reasoning and from descriptive analysis to reflective critique. Participants also showed improved ability to select appropriate graphical representations, interpret contextual data, and critically assess the credibility and sufficiency of statistical information. These outcomes underscore the potential of culturally relevant instructional design to foster holistic statistical literacy. The study contributes both theoretically and practically by offering a validated model for integrating cultural contexts into mathematics education, thereby enriching prospective teachers’ curriculum and providing a replicable approach for diverse educational settings.

The aim of the research is to describe the results of designing number pattern questions used to measure the mathematical thinking abilities of students with a kinesthetic learning style. The research subjects consisted of 5 class VIII students with a kinesthetic learning style. The type of research is design research with 5 stages, namely: Preliminary Design, Focus Group Discussion (FGD), Trial, Interview, and Retrospective Analysis. The data collection techniques are learning style questionnaires, tests and interviews. The data analysis used in the research is qualitative. Based on the results of the FGD, number pattern questions can be used to measure mathematical thinking abilities, because each question leads students to bring up specializing, generalizing, conjecturing and convincing aspects. Based on the test results, it is known that students can write specializing, generalizing, conjecturing, and convincing forms. Specializing is seen when students write the form of adding numbers for each term. Generalizing is seen when students find patterns by listing them one by one or using tables, conjecturing when they find the general formula, and convincing is seen when they find other ways to prove the answer. Based on the results of the interview, students' answers were obtained through the activity of managing and simulating questions using body parts.

This research is motivated by the persistent low level of students’ numeracy skills in Indonesian secondary education. Several pedagogical approaches that may enhance students’ numeracy include the use of digital worksheets, integration of Computational Thinking (CT), and incorporation of Palembang local wisdom as contextual learning elements. This research aims to describe students’ numeracy skills through the use of CT-based digital worksheets with Palembang local wisdom context, an approach not previously explored in existing studies. This research employed a descriptive method using a qualitative approach. The research participants were 34 tenth-grade students at MAN 2 Palembang, while the research sample consisted of three students representing high, moderate, and low numeracy skills. Data collection techniques included pretest, posttest, and interviews. The results indicate clear variation across ability levels, with distinct differences in numeracy indicators interpreting analysis results to predict and make decisions. High-skill students demonstrated mastery of all numeracy indicators. In contrast, moderate- and low-skill students showed partial or minimal indicator achievement, particularly in interpreting results and constructing conclusions. The study implies that CT-based digital worksheets embedded with Palembang local wisdom contexts can support students’ numeracy skill.
