I created this for my introduction to agriscience to get to know my students strengths in each unit without giving them a test. The way they fill it out is the following:
Red light: I have no clue about the topic
Yellow light: I know somethings or I have heard a few things about the topic
Green light: I can take the test right now and I'm good to go.
I use this when making groups for the class according to each unit.
