In case you were wondering... No, the Buck is not changing its model for Project Based Learning again. We did that in 2015 and made sure to write a whole blog post about it so people wouldn’t be confused. Our professional development, materials, and publications will continue to be based on our model for Gold Standard PBL. The new High Quality Project Based Learning Framework, just released this month, is a separate thing, although we were involved in its creation and promotion—and our model is aligned with it.
