Well, here is the somewhat belated blog entry, awaiting on my actually making the oobleck with my girls that Keasty set as homework. Disgusting stuff to feel, btw! Interesting how it really feels like a viscous liquid, but when you squeeze it, it seems to be a solid. My understanding is that it's really a liquid - cornstarch is a long chain polymer, and the molecules all get tangled up with each other under pressure (not really bonding), causing the solid-like properties. If I'm wrong (which I may well be!) someone let me know!! Interesting, & my girls had a bit of fun too :-)
Keasty had set another question for his students to follow up during week 3 - what happens if you put a beaker with water on scales, then stick your finger in it? Well, having tried it, it got heavier, which I'm thinking is due to the increased pressure on the water molecules by the finger transferring in part to the scales (and in part, by displacing the water) - you can feel some pressure (it's not like sticking your finger in air!), and every action has an equal and opposite reaction.
The other homework he'd set was handed back & discussed - we from Mandi's didn't really have a handle on what had been set, but got the gist of parts of it via the discussion (the group had to make pancakes, then fill in a worksheet. One e.g. was when drawing particles, students should show them in motion, not stationary).
So I learned about a couple of common misconceptions in those two activities. There was a handout for the common misconceptions of 'bit ideas' to help with assignment 2a. Where Keasty had tricked me on the water in a beaker, very little was in question in my mind with the handout which is a bit of a relief, but makes me wonder how differently I might perform on a multi-choice vs. an extended response test (hope not!). I have come to the conclusion that it is easy enough to get by quite well as a learner in science by mostly understanding an issue, but actually teaching that issue requires a far more comprehensive understanding to do it justice properly. It will require research into the best ways to teach each and every topic prior to entering the classroom, and I imagine it will take years to develop that PCK (if I ever succeed to my satisfaction). This isn't really isolated to science, but it is so diverse that I think it might be a bigger task than most subjects!
It was great to be in another lecturer's tute as something different - got to see a different approach to teaching & the greater the variety in this regard, the more ideas I get. Keasty is a very entertaining teacher, which is immediately engaging. I imagine if the content got a bit dry, Keasty's humour would overcome those moments, and I wonder whether I can ever manage to do this. I suppose I'll find my own style, but it would be good to keep the kids smiling in time to come. I liked the way he got regular feedback and was very inclusive via the 'picking on' everyone tactic. It's a little confronting, but I suspect it breaks down barriers and creates a 'safe' environment within a group in a short space of time. Another tip he shared was to deliberately withhold answers to questions posed in group discussions - even if the first student response is correct ("tell me more"). This helps everyone to get thinking. More craft knowledge to assimilate....
However, the key focus of the tute was on lesson planning. I loved the way we each got up and added to the white board one piece of information about cells. I recalled a few things, but as a group we knew a whole lot about them! This is a really great (and again inclusive) tactic that I will certainly bring into my classrooms. Although, it really only worked because we *did* know quite a bit as a group - it wouldn't be of much use unless you could expect the class to have a reasonable depth of knowledge in the topic.
I also liked the pair and group work structure. Three pairs all working towards one final set of lessons. It allowed sensible conversation (when there's more than two or three in a conversation, it always seems inefficient) but still was involving working in a team of 7. This is the most effective group work structure I've seen yet. Anyway, as to lesson planning, it was really good, and for me the biggest highlight was the excellent ideas that you can get when working in a group vs. on your own. I really think our lesson was significantly better working in groups, than it would've been if any of us had worked individually. This isn't something we're likely to have the benefit of once we're teachers :( The lesson plan structure seemed pretty good, but there will be bits that I might add for myself, when I'm on practicum. For e.g. enabling prompts, extension activities. Assessment - will I only have this in the 'what will I be doing' category? It might be useful to specifically target informal assessment ideas in a separate section. What about my own learning outcomes? I also found last year that a section on anticipated difficulties with associated mitigants helped me focus on individual problems within previous sessions, and how to manage or resolve them. A blend of last year's maths and this year's science plans might work out best for me.
So that's about it for tute 4!
Until next time....
