Montessori education is the oldest and most widely implemented alternative education in the world and includes a full system of lessons and hands-on materials for children from birth to 18 years, presented individually, and embedded in a philosophical framework regarding children's development and its optimal conditions. The objectives of this…

Although Montessori is the most common unconventional education model, no multi-state study has compared standardized test proficiency of Montessori schools with districts. Here we report on this for the 10 states/regions with the most public Montessori schools (n = 195). In 3rd grade, Montessori schools were less proficient in math but more…

Montessori education was developed over 100 years ago, and persists as a marginal 'niche reform' of the standard model. Here I discuss two unresolved dichotomies in early childhood education -- the tension between work and play, and between structure and freedom. I explain how Montessori collapses and thereby resolves the dichotomies, and does so…

The math curriculum of the Montessori system of education for children ages 3-12 is distinctive, incorporating multiple manipulatives and educational practices which have theoretical and empirical support in research. However, studies investigating the math achievement and learning of Montessori students and alumni have not consistently found…

School liking shows clear associations with academic success, yet we know little about how it changes over levels of schooling, what predicts liking school at each level, or how attending alternative schools like Montessori might impact liking. To better understand school liking across time and education settings, we surveyed adults about how much…

Montessori pedagogy is a century-old, whole-school system increasingly used in the public sector. In the United States, public Montessori schools are typically Title I schools that mostly serve children of color. The present secondary, exploratory data analysis examined outcomes of 134 children who entered a lottery for admission to public…

Part II of this two-part article continues the discussion of what Maria Montessori viewed to be the important components of her educational system. Because she developed the system over her lifetime, we prioritized later accounts when contradictory accounts were found. Whereas Part I focused on the environment, Part II examines the second and…

Maria Montessori developed a form of education in the first half of the last century that came to be called by her surname, and research indicates it often has positive outcomes. In the years since its development, tens of thousands of schools worldwide have called their programs "Montessori," yet implementations vary widely, leading to…

School reform is an important national and international concern. The Montessori alternative school system is unique in that it is well-aligned with the science of healthy development and learning, has strong social-emotional "and" academic outcomes, is virtually unchanged in over a century, can be applied across all the school years,…

Quality preschool programs that develop the whole child through age-appropriate socioemotional and cognitive skill-building hold promise for significantly improving child outcomes. However, preschool programs tend to either be teacher-led and didactic, or else to lack academic content. One preschool model that involves both child-directed, freely…

In the United States, children are often given the opportunity to engage in pretend activities; many believe this kind of play benefits children's development (Haight & Miller, 1993; Haight, Masiello, Dickson, Huckeby, & Black, 1994; Parmar, Harkness, & Super, 2004; Roopnarine, 2010). Recent research has shown, though, that when…

Montessori classrooms vary in the degree to which they adhere to Maria Montessori's model, including in the provision of materials. Specifically, some classrooms use only Montessori materials, whereas others supplement the Montessori materials with commercially available materials like puzzles and games. A prior study suggested such…

Although Montessori education is often considered a form of playful learning, Maria Montessori herself spoke negatively about a major component of playful learning--pretend play, or fantasy--for young children. In this essay, the author discusses this apparent contradiction: how and why Montessori education includes elements of playful learning…

Research on the outcomes of Montessori education is scarce and results are inconsistent. One possible reason for the inconsistency is variations in Montessori implementation fidelity. To test whether outcomes vary according to implementation fidelity, we examined preschool children enrolled in high fidelity classic Montessori programs, lower…
