Duplicate Drag Item for Freeform Drag and Drop
How can two items appear the same to a learner so that either one can be dropped on either of two targets? The situation is three targets, four sets of three drag items per set. But in one set of the three drag items, two of the items appear identical to the learner, because either one is correct for either of two of the targets, but not the third target. In short: Two of the targets need the same thing so two of the drag items look identical.
If I take the fifty percent change the leaner gets it wrong, they will have dragged the items correctly, but get an incorrect response.
