Currently when we do our reviews we either get Green or Red feedback as well as occasionally a little pop up box for clarification. When I get a Red it’s obvious and I stop and review what I screwed up. However, when you get Green it can actually one of two things: 1) You got it 100% right. 2) Eh. Close enough. Maybe it was just a typo, maybe you made it singular when it was supposed to be plural, etc. (Are there any more cases?) Case 1 is obviously great. However, you only find out about case 2 if you’re going slow enough to read the little pop up box.
I am suggesting adding the color Yellow (or Green with Yellow stripes or something) to the mix whenever you trigger case 2. Treat it as a “win,” but give visual feedback that it wasn’t quite right beyond the text. It’s up to us to stop making typos or slightly wrong answers, but I think this would help dramatically in awareness that one was made in the first place.
