On the 5/1 Teaching & Learning call we had a lively discussion about "bubbling up" feedback across tools to the student and consolidating it in a single place.
As an example, comments from Gradebook or Assignments could be added to a list and shown in a synoptic tool in Home – similar to Announcements – so that students know when an instructor has left them feedback. Additionally, grading actions could be listed in the history so that students know when their items have been scored.
The creation of a centralized grading service might facilitate the development of such a feature – but this feature could make the user experience more user-friendly.
Commentors, please feel free to provide use cases and tools for consideration.
