A Multimodal Framework for Computer Mediated Learning: The Reshaping of Curriculum Knowledge and Learning

Margaret:

Um, particles are coming up and falling back in.

Teacher:

Okay. Particles are coming up and falling back in.

Points upwards∕points downwards

But what we said before was, that the reason why they were falling
back in was because it was colder up here.

Points pan Hd and then downwards∕Points at pan lid

Okay. So if we look at the particles up here what, urn. If we look at the
arrangement of the particles could we predict this to be a solid, a liquid
or a gas?

If you look at how the particles are arranged up here?

Students:

A gas

Teacher:

Now, how are gas particles arranged? Are they really spread out, or
are they kinda close together, or really close together?

Students:

Really spread out

Teacher:

So are they really spread out here?

Points at the particles on pan lid and circles them

S2:

I think it’s a liquid

Teacher:

Why ? Look at the particles

Points at the particles on the pan lid

S3:

Yeah, I do .Condensation.

Teacher:

Go on

S3:

Condensation is a liquid, ‘cos then there’s water.
