Monday, my chemistry students started their semester final: a three-week, single-partner, no-outside-communication, all-hands-on-deck lab practical. I handed them a stack of papers and told them that I expected to see polished write-ups in three weeks.
Okay, so I don’t give them nothing. They can use virtually anything printed, including their lab notebooks, the textbook, the Internet… Other than people.
But I didn’t tell them exactly how to accomplish the experiments or how to write them up. This is throwing a lot of them for a loop. It’s making them think a little too hard. I had two pairs, who, after pouring a chemical in a beaker and watching it sink to the bottom of a beaker, discuss how to get a chemical to dissolve. After about 5-6 minutes of contemplating various heating implements, acids, and catalysts, I was afraid they were going to actually hurt themselves: I handed them a glass stir rod.
But the thing is, as I struggle to not talk or nudge kids in particular directions (which makes me think about how much/little I do during the rest of the year), they’re realizing how much they rely on being told what to do. They’re finally thinking about what to do rather than what I say. And to do this, they have to ask questions of themselves (and their partners).
I’m starting to think about how to give more goals, give fewer questions. It’s kind of a riff off of Dan Meyer talking about removing questions from textbook problems to make things more interesting/compelling/think-y. [Hmmm… curriculua as a state function? Many paths to get to the end?]
