Lethlet's Best Bits
Here I share insights in teaching physics.
People often find the concepts of physics difficult and teaching them more so. Physics is a linked collection of abstract models best explained with mathematics - so it is hardly surprising.
Surface learning - 'what happens' we can do experientially.
But deeper understanding requires an abstract model and it's one heck of a leap for students.
Let me explain with a question
What is a kilogram?
Is it a lump of iron we use to compare weights?
Is it a number we use to work out something's weight or its momentum etc?
Is it a measure of the mass something possesses?
OK, what is mass?
.... if we keep going we'll end up at the Higgs.
No way would you teach a bunch of years 7s about mass using Einstein or Higgs.
Often however we do try to take our students from concrete thinking into the weird abstract world of physics in one huge leap. It's really not fair.
They need a half-way point between 'real' and 'surreal'.
This is where my models come in. They are based on familiar physical things, but the fundamental concepts are sound.
