Can she be telling the truth?
As a college instructor, I use Camtasia to create lecture videos, complete with embedded quizzes, and post them on Screencast. Students are required to watch the majority of the videos and answer most of the questions correctly to receive points. Recently, Screencast reported one particular student viewed only 34% of a lecture but answered 100% of the questions correctly. She explained the discrepancy was due to her viewing part of the lecture on one computer and then viewing the rest on another computer. Students often watch the lectures in chunks, which are recorded on Screencast, so that's usually not an issue. Is it possible that she could watch the entire video, maybe over a few sessions, and it wasn't recorded on Screencast? Obviously, I'm on the lookout for academic dishonesty (students passing answers along to other students) but don't want to accuse someone unfairly. Thanks!

Yes - generally, because Screencast doesn't ask users to "Log in" but rather just give a name, it just tracks progress with what we call 'session data'. So, if a student picks up viewing on another computer, it looks like a whole other person to us.
Leveraging quizzes and viewing data are a great way to encourage engagement and get feedback about students' understanding, but we would not consider them a secure way to guarantee grade assessment.
