MDRC+PBL Literature Review

The concept of project-based learning (PBL) has garnered wide support among a number of K-12 education policy advocates and funders. This working paper builds on and updates a seminal literature review of PBL published in 2000. Focused primarily on articles and studies that have emerged in the 17 years since then, the working paper discusses the principles that underlie PBL, how PBL has been used in K-12 settings, the challenges teachers have confronted in implementing it, how school and district factors influence its adoption, and what is known about its effectiveness in improving students’ learning outcomes.
