Most schools have the same philosophy or culture whether they readily admit it or not. This culture is the mindset of “one and done”. This transaction of turn in the assignment, teachers stamps a grade, points go into a gradebook, and the transaction complete.
Schools need to shift away from this to a culture of revision. By shifting the culture we can start to move away from the goals being on assigments to learning.
Issues to making this shift
1. Time
2.Student Case Load
3. Adjusting rubrics
Time is always a monster. We must look at how we use our class time, what the goals for year are for the class, and then begin to structure how we teach and deliver. We start in small doses and gradually shift the flow over time. Student case load is another problem. When tackling 150+ kids it is tough to manage. Schools need to look at how to structure teams and teachers so caseloads are 100 or less. Rubrics need to change how they are used. They should be used as formative instead of always being summative.
I agree with your points, Aaron. To add… rubrics should be changing in PBL classrooms anyway, because teachers should not be trying to retrofit their textbooks into “projects” (a hurdle many have difficulty with). Also, formative assessments are often relevant to components of a project/product, but in a perfect world the summative assessment should apply to the whole, not pieces, of the product.
