In keeping with my theme of focusing on the process of differentiation, I am going to highlight posts on project-based learning (PBL) this week. I’m kicking this off with a fairly detailed description of PBL that can be found on one of the very best education sites out there—Edutopia. Click over and read it if a) you don’t know what PBL is, b) you know what it is and want to learn more, or c) you want to find materials to share with others (e.g., colleagues, families) who may have questions about using PBL in K-12 classrooms.
