After the modules are submitted I select some students and make comments or ask questions about their module submissions. The next day I may not remember who I corresponded with and have to go in to every module submission to find out.
In BbL there was a feature ‘Tree View’ and you could see at a glance the list of all the submissions and the names of the people who responded to them for each module. Do you remember this feature and does it exist in Brightspace? Have you figured out how to see a list of all the contributors to a module without going into each response one by one?
