Shuffling Answers vs Random Stacks vs Drag Sequence
I'm puzzled and by trial and error cannot figure out the following.
When using the Drop and Drag question type, what's the difference between:
1. Setting Shuffle to Answers
2. Using Stack Random under DROP TARGET Options and
3. Adjusting the Drag Item Sequence (invoked by the ellipse after the Reveal drag items one at a time check box)?
I'm attempting to show one letter (object) at a item and have them randomly appear. I've placed all the alphabet character (objects) on top of each other, so they'll appear one at a time at the same location (that is working) but I have the impression that the letters are not appearing randomly and are appearing as I originally stacked them.
