Making Projects Click. In 2012, the Buck Institute for Education (BIE) received a generous grant from the William and Flora Hewlett Foundation to help provide more deeper learning opportunities for teachers and students. With this funding, BIE conducted a beta pilot of PBLU. Building on that experience, BIE created PBLU 2.0 and relaunched in April 2014. This version of PBLU includes exciting new projects from partner organizations and sponsored classes by BIE.
