I  know that in science, organizations like AAAS have worked hard to develop these progressions for many topics and created resources (Benchmarks, ATLAS, etc.).  But for some topics these need to be developed by the teacher.  And even with the AAAS resources, developing these learning progressions into a course that helps students connect everything together is the job of the teacher.  Collaborating on these tasks with other teachers is extremely worthwhile - I just wish this was valued by more school districts and administrators by allowing more time for these things during the school day.  Many seem to think that "courses" are already planned out.  I even had one superintendent that told me "Any minute not spent with students is a waste of time for teachers" - she was obviously lacking in knowledge about what professional teachers do with their time.

I have often focussed on putting feedback on writing, similar to the last question, but have failed to include the preceding sentence - I agree that both are important.

I would really love to do this, but I think this is much easier in a face-to-face class.  I have ideas about how to do this online using Google Docs, similar to how we are doing it now in class.  Anyone have any thoughts about how to do this?

I would have liked to see more specific discussion about the creation of selected-response format questions. I know "concept inventory" type questions that were developed using student misconceptions from previous written assessments are extremely valuable at assessing student learning, especially when compared with traditional questions from a textbook publisher.
