I came to an idea about drawing functions in moodle. I prepare mathematical exercises for my students in flash and i would like to insert a swf file (flash question) inside of quizz and then another question in which students should draw the functions inside of coordinate system. Does such plugin already exists? Maybe an idea for developers?
"...question in which students should draw the functions inside of coordinate system..."
Do you mean that students should really draw the graphs (with mouse?) or give the function of graph...?
We have several ways to create graphs but if they are needed in quiz it may be possible to check the answers (notations) - checking the correctness of curve may be more difficult...
