multiple means of representation

Foundational literacy is central to participation and subsequent learning, yet the instructional routes through which beginning readers encounter print are not equally accessible to all learners. In Tanzania, renewed attention to systematic phonics and early-grade reading has increased the relevance of decodable texts: texts designed to give learners opportunities to apply previously taught grapheme–phoneme correspondences. Their instructional value, however, cannot be assessed only in terms of the linguistic structure of the text. Classroom activities, teacher directions, response requirements, assessment procedures, and available formats can either widen or restrict access. This scoping review maps literature and policy- and curriculum-related evidence concerning decodable or phonics-oriented early reading in Tanzanian primary education and examines the extent to which the evidence engages with accessibility, learner variability, and Universal Design for Learning (UDL). The review follows PRISMA-ScR and considers literature published between 2014 and 2026. The synthesis indicates a plausible pedagogical alignment between controlled text and the development of decoding, while also revealing a major gap in directly tested evidence on inclusive adaptations of decodable materials in Tanzania. Across the mapped literature, accessibility is more often treated as an implementation concern than as a design principle embedded in reading materials from the outset. The review therefore advances the concept of inclusive decodable-text pedagogy, in which systematic phonics is retained while unnecessary sensory, motor, speech, and communication barriers are reduced through multiple means of representation, action and expression, and engagement. Implications are developed for curriculum design, teacher education, classroom practice, formative assessment, and future research. The central conclusion is that decodability and accessibility should be treated as complementary properties: a text may be linguistically decodable yet still be instructionally inaccessible if participation depends on a single route that is unrelated to the intended literacy skill.

Introduction Universal Design for Learning (UDL) has emerged as a prominent framework for promoting inclusive education by addressing learner variability through flexible curriculum design, instruction, and assessment. Although interest in UDL has expanded globally, evidence regarding its implementation in primary mathematics education remains fragmented across diverse educational contexts. This systematic review synthesized empirical evidence on UDL implementation in primary mathematics education and developed an evidence-informed integrative framework to guide research and practice. Methods The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020) guidelines. Searches conducted in Scopus and Web of Science identified 168 records, from which 14 studies met the inclusion criteria. Methodological quality was assessed using the Mixed Methods Appraisal Tool (MMAT, Version 2018), and data were synthesized through thematic analysis. Results Three substantive themes emerged: instructional practices supporting UDL implementation, educational outcomes associated with UDL implementation, and contextual challenges and enabling factors. The findings revealed that effective UDL implementation was characterized by differentiated instruction, multiple means of representation, engagement, and action and expression, supported by accessible learning resources and digital technologies. These practices were associated with improved mathematics achievement, conceptual understanding, learner engagement, participation, and accessibility. However, successful implementation depended on sustained teacher professional development, institutional support, and equitable access to instructional resources. Discussion The review informed the development of an evidence-informed integrative framework that contextualizes UDL implementation within primary mathematics education. By linking enabling conditions, instructional practices, contextual influences, and learner outcomes, the framework extends existing UDL applications and offers a comprehensive model for advancing inclusive mathematics education. The findings underscore the importance of systemic support structures in ensuring effective and sustainable UDL implementation.
