This survey at Carleton University in Canada came to me today. It is actually pretty interesting, and confirms my personal perceptions. I don't know how long it is going to be there, and I am not sure if anyone else has posted this, at least not that I could see, but it is worth posting.
The graphs were revealing, particularly about how close some of these things are, and how different people see them. Taking the comments of the students on board, this means that, hopefully, there will be some advances made in meeting there complaints. On the other hand, the instructors comments about the gradebook echo a lot of other comments made here. I know it is a hugely complex thing, but over time, hopefully, better designs will improve the response times, navigation and bulk handling issues.
