3 come to mind at the moment:
1. Old school veterans who absolutely have to preface anything they say w/ "You know, I've been teaching for 15, 20, 25+ years, and... [insert comment here]"
-You're a wily vet and I respect that. But do you really have to say it every time?
-[Or maybe I'm just jealous cus my 2.5 pales in comparison to theirs.]
2. Presenters w/ text-heavy or animation-heavy powerpoint slides.
-Today's professional development crew presented slide after slide that looked a lil' something like:
-Quick message for you: Just b/c you're using powerpoint does not make your presentation more effective and professional. Your audience is silenced not b/c we are enthused over your amazing new methods but rather b/c we are bored to death.
-I heart this comedian for speaking some truth.
3. The phrase "research-based."
-Not only that, said powerpoint users appended the word "research-based" to virtually every sentence. "And, you know, all of this is research-based!" Congratulations on whatever research article you read, but we educators don't get automatic edu-turned-ons just cus you're droppin' that word.
... Sorry, but had to get that out...
