Checked in here a couple of months ago about our little problem, and no solutions yet, so thought I'd try again with some additional information.
We're adapting existing face to face accounting courses that currently require participants to fill in blank sections of tables with the correct information on quizzes and assignments. Also, they need room for comments below the tables, so that people can explain their work. Easy to do on paper, but in moodle it's been impossible so far. For our last delivery, we ended up with 14 assignments and the exam that had to be downloaded in Word, then uploaded when completed. Not ideal, the course was not well received.
We came across iassign, which looks promising, but only works for older versions of moodle.
Is there a new version of iassign, or some other math- and accounting-friendly tool, that anyone out there knows about?
