Evaluating student work on-line

I agree that teachers need to be aware of the various types of feedback that are appropriate at different times. In Chapter 9 there are the two types "formative feedback" and then "summative feedback". The rubric I have included below (see link below)would be used in a read/write course where students need to write a response to a reading. First of all, I would like to provide comments on their blogs early on to help them apply more critical thinking and learn how to write concise summaries. This work would be done and my evaluation would be more "formative". Possibly I would use an audacity file or a comment in their blog that will guide them toward our goals.

The rubric I created on Rubistar would be the "summative feedback" for a final posting. Possibly this would be used after two or three other posts have been made. I think students need a warm up, coaching, and then a copy of the rubric so they can evaluate themselves before my eval. I would also like to include peer evaluation using questions. Students sometimes focus too much on how it is written than what is written.

I looked at Edina High School's rubrics and I got some good ideas on how to have a final summative eval of all blogs. The criteria included:
-posted on time
-all of the posts were submitted
-Used correct grammar and mechanics most of the time
-Responses were thoughtful
-Commented on at least two times for each post
-Applies specific examples to support points (I added this)

I would have this rubric that is linked below as a final "summative" response to an important mid semester assignment.

I have attached a sample of a rubric I would use in a Reading/Writing Blog Post. Click here on link.
