The few UX things can make for a really frustrating experience. You don’t want to push away your users in their first testing.

1. Change the word “gaps” to “blanks” for English audiences. It fits the common phrase “fill in the blanks” better. And maybe call it that too.

2. Don’t make the blocks move around for the drag and drop. It makes for a frustratingly slow process to find where the word you were about to grab moved to.

3. Don’t just correct a wrong answer, show what the user chose. I had too many moments where I was convinced the answer was what I had selected. Even using the red/green doesn’t quite make sense if you’ve replaced an incorrect answer with a now correct answer.

3. Consider doing the check after all words have been dropped in so they can read the sentence as a whole. And thus give them the chance to change their word choice.
