Lottery-based identification strategies offer potential for generating the next generation of evidence on U.S. early education programs. The authors' collaborative network of five research teams applying this design in early education settings and methods experts has identified six challenges that need to be carefully considered in this next…

To address inequality, philanthropists support "no excuses" schools in majority-Black low-income communities. While the model has raised achievement, its practices are problematic from a social justice lens. Montessori is a highly contrasting model, and over 25% of public Montessori students are Black. Here we examine whether Montessori…

In this study, we asked whether Montessori schools, which tend to have high student engagement, are associated with lower average rates of chronic absenteeism and/or smaller racial disparities therein relative to non-Montessori schools. We use multilevel modeling to answer this question, following an approach proposed in Author et al., (in press)…

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…

Common methods of measuring discipline disproportionality can produce contradictory results and obscure base-rate information. In this paper, we show how using multilevel modeling to analyze discipline disparities resolves ambiguities inherent in traditional measures of disparities: relative rate ratios and risk differences. One previous study…

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…

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…

The institutional environment of US school systems has changed considerably over a quarter century as standards and test-based accountability became central ideas in both policy texts and discourses about improving education. We explore how US school systems are managing in this changed environment by focusing on school system leaders'…
