Canvas states "Total Activity records any time spent viewing course content that exceeds two minutes. If the time between a new activity and the last completed activity is under ten minutes, all time between these two events will also be included."
I have tried to verify this, and have not had success. For example, a "refresh" of a browser window is considered "activity". Oh, really! I have also logged out, logged back in, an the clock appears to keep running continuously. Hmm, I guess Canvas considers this as activity, logging out and then logging back in.
Right now, I tried this little experiment:
Logged into Canvas, went to course 1, noted my activity time in Course 1.
Immediately switched to Course 2, noted my activity time in Course 2.
Stayed in Course 2 doing absolutely nothing. Then, 5 minutes later refreshed my browser.
Course 2 reported 5 more minutes of activity. Well, doing nothing in Canvas is not activity. Far from it. I guess refreshing the browser by Canvas is considered activity... this is all I did.
Then, I immediately switched back to course 1. Guess what, it had added 15 minutes to course 1 activity time, even though I only spent 5 minutes doing this experiment and did nothing in Course 1. For 5 minutes I was staring at Course 2, not Course 1. Even worse is that Canvas thinks I spent 20 minutes in Canvas, if I were to add up times in each course.
The point is that this continues to be a bogus calculation and cannot be accurately repeated or verified. As such, it is very misleading to those who think that they can track student's "activity" using Canvas. This is why I suggest that it be removed.
My conclusion is that there must be people who like seeing numbers, regardless of how meaningless or incorrect, than seeing the reality that "activity" in Canvas cannot be tracked.
