    When looking at student success (or lack of success), it is great to see participation, but the page views is of dubious value. If a student simply clicks through pages, they get counted the same as someone who actually spent time reading the content of a page. I know we can see the time spent if we look at the login report (which I think needs to be more robust rather than only giving us the start time for the last time a page was viewed), but I would like to see something such as total time spent in course or total time each day etc. on the course analytics page along with participation and page views.
