Transforming teaching and learning with PBL across a district is a complex and often-underestimated task. PBL is not a simple addition to a teacher’s “toolbox” – for many teachers, it will be a revolutionary change in practice. As a school district leader, you’ll need to help principals, teachers, parents, and your community understand what PBL is and why it's a good idea for 21st-century education. You’ll need to consider changes in everything from teacher professional development and evaluation, to grading and assessment, to organizational culture and the use of technology. BIE provides resources to help: videos that showcase powerful examples, research on PBL’s effectiveness, and books and online tools that guide teachers in planning and conducting effective projects.
