Implementation of Montessori Pedagogy as Holistic Educational Approach in Day Care Centres in Mtwara Region: A Systematic Literature Review

Abstract

This systematic literature review synthesized existing empirical evidence on the implementation of Montessori pedagogy as a holistic educational approach in day care centers, with particular attention to the Tanzanian context and the Mtwara Region. Guided by an integrated theoretical framework combining Bronfenbrenner's Ecological Systems Theory and Maslow's Hierarchy of Needs, the review analyzed empirical studies published between 2015 and 2025. Studies were sourced from Scopus, ERIC, JSTOR, Web of Science, PubMed, Research Gate, and Google Scholar. A total of 42 peer-reviewed studies met the inclusion criteria, including 4 empirical studies conducted in Tanzania. The synthesis examined three dimensions: influence of Montessori teaching methods on holistic child development, contribution of Montessori learning materials to holistic development, and influence of teachers' competence on Montessori pedagogy implementation. Findings indicate that Montessori teaching methods significantly enhance children's executive function, social-emotional regulation, and intrinsic motivation compared to conventional approaches. Montessori learning materials, when accessible, complete, and properly maintained, support fine motor development, sustained attention, and peer collaboration. Teacher competence, particularly formal Montessori training and ability to facilitate self-directed learning, is a critical determinant of implementation fidelity. Critically, the review identified a substantial research gap: no studies have systematically examined how Montessori pedagogy is implemented in Tanzanian day care centers, particularly in rural regions such as Mtwara. Most existing Tanzanian research focuses on primary school preschool units, excludes children aged 2-5 years, employs descriptive surveys without child outcome measures, and relies on teacher self-reports without observation. The review concludes that while the benefits of Montessori pedagogy for holistic child development are well-established internationally, the influence of socioeconomic context, cultural adaptation, and teacher training in low-resource Tanzanian day care settings remains unexplored. This review demonstrates an urgent need for mixed-methods, context-specific research in Tanzanian day care centers.
