Alexia, I'm so sorry but still running into glitches on this on after doing more testing on this. Here is what I discovered:
I want to allow students 2 attempts to get the correct answer - so in essence they should only be able to click the Try Again button 1 time which takes them to attempt 2. If I set the TryAgain value to 2 for the number of attempts, it then let's them click Try Again 2 times (which now allows 3 attempts). So I ended up setting the value on Step 3 to Equal/Greater than 1.
In addition, we are also telling the system to show the Incorrect Layer after the Variable reaches the set value, which in my example, is 1. But, when testing this, if I select the correct answers on the second attempt, it still displays the Incorrect layer because I clicked Try Again 1 time, as set in the #3 condition. Shouldn't it first look at whether the answers are correct before being overridden by the variable?
I'm very perplexed on this one. It would be great if there was some way we could add a RESET button in a future release for Drag and Drop activities which allows users to set the draggable items back to their original position, if so desired.
