The modestly sophisticated kind of homework system you're describing is the sort of thing that is probably best left to a dedicated (on-line) system -- whether a proprietary one such as WebAssign or a free local-sever-based one such as WeBWorK. A huge amount of effort, instructor feedback, and field testing has gone into development of such systems, and it seems a wasteful task to reinvent what has already been done (unless, of course, you want to develop and disseminate such a new system yourself).

Both generate unique homework exercises for each student by drawing random samples from real-world data sets. I have already used them successfully in an intermediate undergraduate theory course in financial economics. But something came up yesterday when I was putting the finishing touches on a prototype for multiple-choice quizzes, and I suppose it should have occurred to me before I even started. I included radio buttons for the answer choices to each question, knowing that free CDFs cannot export, but thinking that the answers chosen could be dynamically updated in a table, and students could then use the table to enter their answers into a web form for submission. No problem with this as long as the quiz is completed all at once. But students are not be able to come back to complete a quiz that they had started earlier because free CDFs cannot sa > ve the interface state and do not allow importing (which, presumably, could be used to create a file to do the same thing). All this being said, I was wondering if someone on the list might confirm, and perhaps suggest a workaround if one exists. A volume license for Player Pro is not an option at my institution. > > I think CDFs are neat, but the inability to save states, severely limits their usefulness for homework, and I am now wondering whether I might just as well use Mathematica to create a workflow to generate a unique PDF for each student instead of a CDF. Even if a student does not print a PDF, they can always annotate them, and in that way, save their work. > > I guess this is a shout-out to Wolfram to consider expanding the capabilities of free CDFs for these purposes. > > Regards, > > Gregory --- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
