Best Evidence Encyclopedia (BEE) (Center for Research and Reform in Education, CRRE)
The Best Evidence Encyclopedia (BEE) is a free website created by the Johns Hopkins University School of Education’s Center for Research and Reform in Education (CRRE). It is intended to give educators and researchers fair and useful information about the strength of the evidence supporting a variety of programs available for students in grades K-12.
The BEE mostly consists of systematic meta-analyses of research on effective programs in reading, mathematics, writing, science, early childhood education, and other topics. It also contains articles on review methods and on issues such as special education policy and evidence-based reform. All articles are written by CRRE staff, students, associates, and collaborators, past and present. The articles are technical reports written in the process leading to publication. Almost all entries have been published, or will be. However, we provide the technical reports online to make our reviews available before publication, and we keep them online to enable readers to access the information easily and at no cost.
