Have you ever taken a task that is largely visual or hands-on and tried to explain it to students verbally? Fixing a thermostat, assembling a doll house, finding a section of the library, registering for a 30-day trial on Study.com — ever try to reduce that to words in a way that none of your students can misunderstand the instructions? Better yet, have you ever given that challenge as an assignment for your students to tackle? This is one of those contexts where a picture really is worth a thousand words.
Do you teach online at all? If so, you’ve got a discussion board set up (or at least, you should). We always want the students to be active and engaged on the discussion board, but when they do, things can get unwieldy pretty fast. Ever had that student who just refuses to hit “Reply” and instead always starts a new thread? That’s irksome. On the flip side, sometimes you get an original post, and then a reply, and then a reply to the reply, and then a reply to that reply. You end up having about 18 nested layers, with the last few being only a few pixels wide. Not cool.
