I like to think I am a happy person

It is one of my more cherished delusions, for realz. But there are things that make me happy and I like to share with people. However, this week, I have been reminded that 'people' and 'students' can be a mutually exclusive group, for values of 'people' which mean 'people who will appreciate the happymaking of the things'.

Here are some examples.



My students said "why would anyone go to the trouble of making food look that good when all you're going to do is eat it?". My students are philistines.

My students said "What? Why is this even funny? What is this song? Why are you laughing?" My students are young and do not recognise the juxtaposition.

The perils of trying new things, and why it's important to try

I can totally see why teachers, heads of departments and school managers and governors stick to what they know. It's just so much easier than setting fire to the past and starting from scratch (or even just hacking the past back to rubble and then trashing the useless bits).

So, one of the things about the new units we're using in junior science is that they need fine-tuning as we teach, and that is hard work. It's worthwhile work, but it's not like any of this stuff has been tested before, or even like any of the teachers have worked in schools where science is taught this way. So each lesson is a learning experience.

Today, I learned that some students are idiots. Well, that's a pretty mean way to describe it, so let me say it in a more professional way. Some students are so accustomed to being given knowledge that they find the most simple of self-directed tasks daunting - even paralysing. So they cover it up with not caring. This, then, is the most nerve-wracking part, for me. I am trying something new, and expecting students to try something new, and expecting my staff to try something new.

Sometimes, I wish we could all have a group hug.

The scientific process and other monolithic entities

So many students think of the scientific process (okay, if they think of it at all) as a set of data-in/conclusion-out, cookie-cutter, pre-made experiments. They get called investigations, but the outcome always seems pre-determined. The teacher always knows what the answer should be (even if your crappy following of directions has resulted in something quite, quite different).

One of the things I am loving on at the moment? The exemplar I am making involves me in my favourite part of the investigative process - the bit where I do some mini-tests and alter my method accordingly. I'm not recording data, just playing around within the limits of my investigation to make sure that my method is going to work. I love it.

I hope to have some success soon though - all those internet tutorials made it look easy! Here are two pics of the dismal failures so far. One was using a hot iron, one a cooler iron. I think maybe I need to let the baking paper cool before I peel it back *sadfaces*

One of the things I like about being a teacher...

Is trying things first.

Next term, the Y10 class is doing a unit based around investigations and different inquiry processes. It features self-direction, individual learning outcomes and all sorts of happytiems so-hot-right-now educational features.

But the bit I am happiest about is that there is an exemplar for the first round - for very low ability students, they can use the exemplar as a template and basically plod along in the exemplar's footsteps.

Naturally, I get to make the exemplar.

Even that wouldn't ordinarily be enough to excite me, but I am making my exemplar about using plastic bags as t-shirt transfers. Yeah, I know, exciting right?

Look at this example of what someone made with plastic bag transfers:



I was inspired by three posts on Filth Wizardry - post one, post two, and post three.

And there is lots of science behind this - like why the particle structure of plastics makes them prone to melting, not catching alight. Why some plastics are softer and more melty than others. Like where plastics come from in the first place. Even though the tutorial gives basic instructions, there is still plenty of scope for investigation and coming up with a solid hypothesis. My exemplar deals with the effects of plastic type, holding the temperature and time of fuse constant. At the moment, though, I am freeform experimenting, to get the basic range of my constants settled. I will have pictures later.

So, I'm hoping that a few other students will choose other plastic recycling topics to use for their first investigation. I have some awesome tutorials on fusing plastic bags - here, with patterns if you want to make a rain hat or bag and here, with some more crafty ideas, and even a video tutorial:



But I need more! I'm going to exercise my google-fu later and come up with as many awesome plastic recycling ideas as I can. If any readers have ideas, I'd be delighted to hear them too!

But getting back to this unit of learning. Not many students are going to grasp quite what I'm on about quickly and be able to run with it. Some will, and I am really looking forward to seeing what they and their awesome imaginations come up with. But many will need a lot of support to get through it. That's where the exemplar and some supported options come in - at least for the first round of investigations. And if I get to play round with making t-shirt transfers out of the fifty million plastic bags littering my house, that's even better.
