"the science one seems very unambitious (to me as a layperson). They emphasise learning knowledge before experimentation and there seems to little consideration in learning skills like applying the scientific method and scientific enquiry (it maybe that this is a demand of the National curricula so not specific to this school so please clarify)
I'm a science teacher and have been reading their blogs about how things work there with interest. I have a lot of thoughts about this, sorry this is long:
There's a pendulum in science education that swings between Content and Skills. (Right now in most English schools running the national curriculum, it's mostly over in the Skills end but I think it is swinging back towards Content? I teach in an IB school and the pendulum is right the way over to Skills at the expense of Content)
The reason it swings back and forth is because no one really knows how best to get the Scientific Method over. Should you start in primary school and set students challenges to find things out through experiments they designed themselves or should you give students essentially experiment "recipes" until they understand enough science in order to plan an experiment?
The advantage with prioritising skills is that students will have a greater facility with the concepts of variables and experimental control but the disadvantage is that if students don't understand the underpinning science, there might be too much going on to be able to learn anything at all.
It's like, telephone numbers are only a certain number of digits long because you can only remember so much new stuff at once. If your teacher expects you to understand the names of some chemicals, the signs of a chemical reaction, the equipment, the procedure AND what a fair test is plus how to make observations, you're going to come unstuck.
You might be able to do the task but at the expense of making long-term memories.
Plus, as humans, we think concretely until about Y8-9 and then abstract thought starts to take over. There's no set timetable or anything, and it's not related to how smart you are, it just happens when it happens.
Concepts like accuracy vs. precision, variable control, hypotheses (et al) are quite abstract. Expecting everyone under Y10 to be able to understand and have fluency in this area is a big ask. It can mean that students think they are no good at science and write themselves off, when all it was that they just needed to level up cognitively.
Michaela's approach appears to be to concentrate on building a content base for understanding scientific concepts and THEN when they understand the science, I guess they will teach them enquiry (maybe at A level?)
This seems to be a lot more brain-friendly and I think they might have the right idea.
BUT as a science teacher, I believe in gently scaffolding the scientific method from the start. There are sets of lessons you can do to bridge the gap from concrete to abstract which have some great evidence to suggest that they work to a high degree.
I think teachers need to be clear what they expect to get out of a practical: do they want to teach a skill or do they want to teach a fact. They can't do both. And a lot of teachers (myself included), try to get a two-for-one out of experiments and it rarely pays off.
Michaela might be on to something and I am watching with interest. I think it's interesting that they go into topics in so much depth and have fewer of them per year. It makes their curriculum look sparse but some of the stuff even the youngest students are expected to retain is at A level standard.
