Re: Timed Notebooks for Student Take-home examinations
I'm probably misunderstanding something, so correct me if I'm wrong: the package would reside on the student's computer and it would generate a notebook for the student to complete. At the time the student "requests" the notebook from your package, you write an encoded string to the notebook itself that basically assigns it a timestamp. Then the student would upload/send you that notebook and you would decode that string? (encoded string + time of upload = time spent) Is that the idea? A student could simply request a notebook from the package twice, say the second request 3 hours later. He would complete the assignment, open the notebook in any text editor and overwrite the encoded string with the new timestamp. I believe the best way to have this sort of thing is by having a system (say a website) where you can keep track of when a file is downloaded and uploaded and *you* keep track of the timestamps. This obviously deviates from your idea of creating a Mathematica package for that, but that's what schools seem to use. Like Chris mentioned, a web Mathematica application seems more appropriate. To prevent/diminish sharing of answers between students, you'd setup a web Mathematica application that required user authentication. Then, you'd be generate problems with different "initial values" for each student (or groups of students, whatever). Igor W.
