is it possible that that a student can uses an interactive graphic animation in a Quize question?
Say, in a case when a student must to measure two sides of a rectangle with a ruler;
student should then with mouse or with the cursor keys move and/or rotate ( 90 grade ) the ruler to the sides of the rectangule so she/he can it measures?
After that student should write in two text fields the width and height of the rectangle.
This could only be done by developing a new question-type plugin.
It woudl be possible to create such a plugin, but I don't know of one that already exists.
https://moodle.org/plugins/view.php?plugin=qtype_ddmarker is the closest one I can think of.
I examined the drag and drop into text question:
but this is not quite the same as what I thought, although it could be used in my case too;
then the teacher could draw rulers; one in horizontal and one in vertical position; the student could then drag ( but not drop! ) the horizontal ruler to the horizontal side of rectangle to measure it's dimension, and write down the value in an approppriate text field..
There's a lot you can do with Moodle and the SWF Activity Module ( https://moodle.org/plugins/view.php?plugin=mod_swf ).
Here's a 3D world globe example: http://blog.matbury.com/2008/11/13/papervision3d/ and a 3D cubes example: http://blog.matbury.com/2009/04/07/interactive-3d-fun/ Both are interactive.
Perhaps, rather than a ruler, something more like a tape measure would be more flexible and easier to implement and use. Learners can click on the starting point of where they want to measure, then drag the mouse to the end point and see the length in cm and/or mm. This would mean that learners could measure any shape at any angle.
You could also make answers acceptable within a certain range, e.g. > 4.8cm & < 5.2cm, so that it's less frustrating for learners. Or you can make the tape measure "snap" to predetermined units, e.g. 0.5cm.
I hope this helps!
