In a few minutes, the students will be making their own pop-ups. Many of these will not work immediately. If something doesn’t work right away, what should you do?
Help students develop the idea that they can figure out what’s wrong with something that doesn’t work. Most things that are faulty have only one thing wrong with them. It doesn’t make sense to start over again, because, most of it actually does work! Also, if they start over, they might make the same mistake again. A much better procedure is to troubleshoot: find the part that doesn’t work, and then fix only that part. Ask students to provide examples of troubleshooting from their experience
