Diagram of the updated model of how engineers learn
2019-04-13
In How engineers learn, there is a diagram "Execute, verify results, Cycle in which the model is modified."
I drew it because I might be able to draw it better now that I have an iPad.

First, I think, "I'd like an A."
For example, "I want to create software with a certain function X" or "I want to eat fried eggs.
Think "How can I get A?"(HOW)
Think, "If I combine B and C, I might get A."

Like, "If you put a frying pan on the stove top and put an egg in it, it's going to be a fried egg."
Model M produces this
I'll actually try it.
I expected to get an A and I got a D.

We now have the observed fact that "combining B and C gives us D, not A."
It's hard to tell that this says "Do" (2025-04-16)
Consider why D instead of A (why)
Model M, which generated the hypothesis that "if you combine B and C, you get A," is wrong.
Modify model M (M')
One thing that was in the 2014 figure but not depicted here is that this correction is a "Why did this happen?" to "Isn't this what caused this?" (2025-04-16).

Using the new model M', we again ask, "How can we get A?" (how).
'Wouldn't it be nice to combine the B's and G's?' and so on.
I'll actually try it.

Q: What is model?
A model is an emulator.
The model is a reality emulator
Postscript (2025-04-16)
To add something that was not clearly stated, this "model" is a "set of hypotheses," and the certainty of the hypotheses gradually increases as one acts on the hypotheses and they turn out as expected.
A model is a set of hypotheses.
Knowledge must be validated by action.
