That is a common problem. In addition to other things might I suggest giving out a handout in the beginning of the class with a list of most common mistakes. Or a website perhaps. That might alleviate the problem a little.

You have a tough problem. Maarten Sneep in his reply did mention some solutions. Paper and Pencil might be better. If you still want to try out alternate means, simple macros might help in a limited way.

One thing you can do is not show the preamble. You can have a personal script which calls the preamble, concatnates the user input, adds \end{document} and typesets it. This prevents typing anything in the worng place.

I ahve not used LyX so I am not sure how well it deals with personal macros. It is possible to write simple macros for doing separate tasks. If you can outline what needs to be done, the list can contibute in a conrete manner. One might be able to create applescript's which ask for user input. Suppose you want to typeset addition of numbers, a script will ask for the numbers and write the code for that.

The more automation you want, the tougher it will get.

Sure. First some background stuff. In my undergrad years, I used to work in IT Department. I havent seen a single software which need not need suport. Things I thought obvious were not shared by users.

Coming to LaTeX. I recently, worte a package to typset Actuarial Symbols (annuities, etc.). A much simpler problem than yours. I did not get it right in the first attempt. Only after testing them in different ways and used by other users, I was able to squash what I hope were the last bugs.

With your problem, your first solution will probably not be adequate. After seeing how your students respond, you will learn what is and is not effective. You will then have to modify the code. If things go well after a semester you will have something good and useful (or perhaps go back to pencil and paper). Donald Norman in Design of Everyday Things mentions that a new product in the market typically needs around 6 revision to get the design right.
