In an era where data is increasingly prevalent, statistical literacy skills are essential for active citizenship and informed decision-making. For future generations, prospective teachers play a role in developing this skill. However, current instructional approaches often overlook the integration of practical applications and local wisdom, limiting students' ability to connect abstract statistical concepts with real-world experiences. The objective of this research is to design a Learning Trajectory (LT) that supports the statistical literacy skills of prospective teachers by utilizing a hybrid learning strategy that integrates local knowledge from South Sumatra as context. A total of 60 prospective teachers from a mathematics education study program participated in this study. A design research method was employed, specifically utilizing a validation study. The research unfolded in three stages: preparation for the experiment, the experimental design, and the retrospective analysis. Data collection techniques included student activity sheet assessments, classroom observations, and interviews. Data analysis involved comparing the Hypothetical Learning Trajectory (HLT) with the Actual Learning Trajectory (ALT) in the retrospective analysis stage to develop the LT. The results indicate that the designed LT guided students through five activities that support statistical literacy: reading and interpreting data tables using statistical situations with local wisdom from South Sumatra as context, interpreting graphs, analyzing and reflecting, exploring outliers, and making conclusions and presenting findings. These findings highlight the importance of integrating local wisdom contexts into statistical education, as well as the relevance and applicability of mathematical concepts for prospective teachers. This research contributes to the design of a learning trajectory based on a local wisdom context that can be applied in statistical literacy learning.

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.

Matematika sosial dan numerasi merupakan kompetensi esensial yang harus dimiliki oleh siswa agar dapat berpartisipasi secara aktif dalam kehidupan bermasyarakat. Namun, hasil observasi awal menunjukkan masih banyak guru SMP yang menghadapi kesulitan dalam mengintegrasikan pendekatan Pendidikan Matematika Realistik Indonesia (PMRI) ke dalam proses pembelajaran. Permasalahan yang dihadapi adalah rendahnya kemampuan guru dalam mengaitkan konsep matematika dengan konteks sosial dan budaya siswa, terbatasnya referensi pembelajaran berbasis numerasi kontekstual, serta belum terbentuknya komunitas belajar yang secara aktif mendukung penerapan norma matematika sosial di sekolah. Norma sosial dan numerasi yang digunakan berkonteks budaya Palembang yaitu makanan tradisional Palembang dan kain tradisional Palembang. Kegiatan dilaksanakan synchronous dan asynchronous dengan melibatkan 32 orang guru dari berbagai SMP di Kota Prabumulih. Kegiatan ini mencakup pelatihan, diskusi kelompok, dan pendampingan secara dalam mendesain konteks budaya lokal, seperti makanan tradisional dan kain songket Palembang. Hasil analisis pre-test dan post-test menunjukkan peningkatan kompetensi guru dengan nilai sebesar 0,714 serta respon peserta yang positif terhadap kegiatan. Temuan ini menunjukkan bahwa pendekatan komunitas belajar PMRI efektif dalam memperkuat norma matematika sosial dan numerasi.
