# Examples of Active Learning

[ Music ] >> A parallel beam of light
is sent through an aquarium. If it [inaudible] shown in the diagram is held
in the water, where does it focus the beam? Ten seconds left. Okay. We're close to 70%, let's
see if we can get to 100%. So go ahead, talk to your neighbor. >> So that part doesn't matter. It's just [inaudible] a glass of water. >> Right. You've [inaudible] aquarium tank, but it's like you've got these
parallel beams coming in. Yeah, you've got the parallel beam
coming in going air, glass, air. And so each of those changes is going to have
a much higher magnitude, which means the ratio of the angle is going to be much higher. So you're going to have more dramatic angle
shifts going air, glass, air than you're going to have going water, glass, water. [ Inaudible ] >> It's going to be like that, right. Whereas if you have the same
thing, and this is water. [ Inaudible ] >> Twenty more seconds. [ Inaudible ] Somehow through a small miracle, we
went from 69% correct to 100% correct. Wow, we're still missing four responses, so let's let those last four
people respond, 62, still at 100%. This is amazing, 63. How is that. Wow, I'm impressed. Those of you who had it right, very
effectively taught [inaudible]. And in the process, everybody really learns. But imagine that we were pouring in a liquid that has the exact index
of your fraction of water. What would happen? So imagine it's not an aquarium filled
with water but some kind of, I don't know, I think Clarissa [inaudible] that's
something that's pretty close to glass. And you put that dense in there. What would happen to this parallel? >> Well I start this as an individual question. You have 30 seconds. Are they one, two, three, four, zero
or more than four ways of defining. I have 56 already. Everybody seems very convinced. The discussion tables. [ Inaudible ] Good. So in fact there are two
ways to define this configuration. Again, we want to think about the four
forces that are potentially happening here. >> What about this? So what would you predict would happen if
you suture both eyes shut for the same two and half months during [inaudible],
both of them are now shut. And then you're going to do the
same experiment that you did before. [ Inaudible ] Do we have predictions? I think we have most people in on their votes. Okay. So you guys said C. Does anybody
else want to offer an alternative opinion? We had two people who voted for A and B. Anybody
have a different idea about what might happen? No different ideas? Nobody wants to say why they
maybe voted for B or A? Okay. Well whoever voted
for A was actually correct. Now do you want to vote, now do you want
to say why you thought A might be true? Or did you vote by accident? Press A by accident. Come on. Who voted A? Nobody wants to admit to it? Alright, well the answer is
A. Why would the answer be A? Can anybody think of a reason? [ Music ]

The teachers posed a question and the students then discussed the process and came up with the solution on their own. I liked the way they electronically submitted their responses and then discussed why the answer was correct.

Great examples of student interaction. I loved the struggle the last teacher had in getting students to speak. I've dealt with it – its awkward – and she handled it gracefully. I like the whiteboards separating the tables – provides a little privacy and ease of visual representation.
