My new Y7 curriculum based on ideas from my first paper (in JBE). Six lessons on "Cells in Systems" led us to co-enacting this model with a nice "What if?" to trigger predictions & generate rich feedback for me.

Teaching without slides – just diagrams and dialogue – we co-constructed these models this week:
Year 7: Allen's rule
Year 10: Lung ventilation
IB1: Positive feedback drivers of climate change
IB2: Viral evolution
I explain how to teach this way in #DifferenceMaker #EnactingSystemsTheory

A short week, as I've been ill, but we enjoyed constructing new ideas:
Year 7: Natural selection
Year 11: Plant Vascular tissue
IB1: Eutrophication
IB2: Muscles intro

No slides needed; just diagrams and dialogue to co-construct meaning. Learn more in #DifferenceMaker #EnactingSystemsTheory

Here's the model I coenacted with IB2, as it didn't fit in the last post.

"We take as given the idea of distinction and the idea of
indication, and that we cannot make an indication without
drawing a distinction. We take, therefore, the form of distinction for the form."

George Spencer-Brown (1969)

Today I taught mammalian thermoregulation with a stock and flow model.
This one is great for making two distinctions that students find difficult:
1. Heat gain & heat loss
2. Mammals work to regulate *internal* body temperature

Continuing with creating stock and flow models in Year 7, today we co-enacted the meaning of these diagrams.
We then dropped balls from 1m to see how high they bounce and infer how much energy is lost to the thermal store.

This year I'm focusing on developing new stock and flow models in Year 7. We're currently studying the energy stores model.
Yesterday we built this model and explored its consequences together through "What if?" questions.
