My Take
This is one of my favorite tools to use and it is especially helpful with reviews. It implements the element of competition as well, which keeps students engaged, and then you can see the overall responses to see how many students got a question wrong and which alternate answer they chose. Students enjoy it as well, so it is very effective in wrapping up whole lessons, or even introducing them to see how much prior knowledge the student already had.
How I Use It
I've used it mostly with reviews of whole chapters/topics to give students the opportunity to see where they're at in terms of understanding the lesson, and it allows educators to see where certain students may be lacking as well so they know what they might need to review more.
