The Buck Institute for Education (dba PBLWorks), a national provider of professional development for high-quality Project Based Learning (PBL), today announces that it has received $2.5 million from the One8 Foundation. The One8 Foundation is supporting the development of supplemental Open Educational Resource (OER) Project Based Learning units for mathematics in grades 6–8. The project will focus on building and testing the PBL units in collaboration with teachers and students in Massachusetts. Once fully developed, these supplemental PBL mathematics units will be open educational resources available to teachers throughout the United States.
