I took a training today that had a small segment on Active Thinking - I think that's what it's called. It's when you have students justify their thinking (in writing) on test questions, typically multiple choice. Here's an example: Which one below is living? a) rock doesn't move or breathe b) frog breathes, eats and grows c) water moves but doesn't eat or grow The orange would be what the student would write. Now, I don't think this is very practical to do on every test item but maybe you could tell the students to pick one problem to do active thinking on or you could specify which one. Even better, you could give students a small slip of paper with one multiple choice problem and use it as a formative assessment. On a quick side note, I do often have my students justify their thinking verbally but have never tried it this way. This could be a great test-taking strategy where hopefully if they do it often enough, they will begin to naturally justify their thinking in their heads. What do you think about this strategy?
