"Perhaps the most difficult aspect of project-based learning for me was figuring out how I was going to assess it. I'm sure some teachers love assessing and marking student work, but honestly, I'm uncomfortable with most grading and scoring. I appreciate feedback and I don't mind giving feedback, but I hate reducing it to a letter, number, or score. To me, it undervalues the learning."
"Once the students had selected a topic from our over-arching theme of civil/human rights, and I had a rubric, it was time for the real work to begin. We started our project-based learning by making a list on the board of things we know about the topic followed by a list of things we "need to know." Basically, we completed the K and W of our KWL chart (PDF)."
"As I design a lesson or assessment, I ask myself if what I've designed, or what the students must master, correlates to the important skills of:
Collaboration
Communication
Critical Thinking
Creativity
My lessons and tests must incorporate one or more of of the four Cs to, in my opinion, be worthy of spending precious instructional time in the classroom.
On another note, the other short rubric I keep in my head is related to differentiating my lessons. Looking at teacher and education author Dr. Carol Tomlinson's list of ways to differentiate in the classroom, you'll notice that this aligns nicely with the four Cs above. Tomlinson explains that the four elements that lend themselves naturally to differentiation are:
Process
Environment
Content
