No talking without raising your hand.
It’s a common classroom rule. But do teachers expect it to be followed always, every time, under all conditions? Really?
What about the times when that one student who never participates calls out an answer? Do we risk not hearing from her after insisting on reminding her to raise her hand?
Or during that magical moment when a class discussion gets going beautifully and you can step back and watch students discuss and debate? Do we stifle the discussion by stopping each student and pointing to the “no calling out” reminder on the board?
Teachers need to be firm in enforcing their expectations. But we also need to be flexible when the situation calls for it. How do we do both? Strike a balance!
