In our older model for the Essential Elements of PBL, one was “Reflection and Revision.” It had a nifty alliteration, but we changed it for reasons you can read about here, so now in our new model for the Essential Project Design Elements, Reflection is on its own and we also have “Critique and Revision.” I got into a great discussion about this on a recent hangout with two of our National Faculty members, Angela Marzilli and Kevin Armstrong. We were joined by BIE staff member Stanley Richards, who manages our work with Lucas Education Research to study the effectiveness of a project-based AP curriculum.
