This week Bob Lochel wrote about 3 Phrases from Math Class we Need to Expunge, which reminded me of the google doc I started and then forgot about. I wrote about it on here before this blog had a following (does it have one now?). So I tweeted and Bob blogged and now I’m blogging again. With enough repetition perhaps people will remember to add to this document the next time they think of a trick students memorized without learning. Or a vocabulary word students really don’t understand the definition of.
What tricks do you hate when students shout out?
What words do your students use without understanding?
What notation do you wish students started using earlier?
Please contribute your pet peeves or pet projects. What would you really like to tell all textbook authors/teachers/tutors?
