Overheard: think-pair-share flashcard shaking

Astronomy 210, Fall Semester 2010
Cuesta College, San Luis Obispo, CA

(Overheard at the end of a think-pair-share flashcard cycle, when students were apparently unanimously voting for the correct answer, but did not seem very confident in their responses.)

Instructor: (Looking at nearly unanimous student flashcard results.) "Wait: remember, even if you think you have the correct answer--if you're just guessing, or if you aren't comfortable being asked to explain your answer, choose '(E) I'm lost, and don't know how to answer this.'"

Students: (No one changes their flashcard answers.)

Instructor: "Okay. If you're really confident of your answers, then shake your flashcards... (Beat.) Like a Polaroid(TM) picture."

Students: (Only a third of the class shakes their flashcards.)
