DESCRIPTION
Introduction to the concept of abstraction, fundamental to Computer Science
TRANSCRIPT
What are these paintings about?
What are these photos of?
How did you do that?
Cats: You ignored, you removed the unnecessary detail.
Dogs: You identified the patterns, the things that all the photos had in common.
We call these two processes ‘Abstraction’
Working in your groups
Make a puzzle, using images from the internet – that require abstraction to solve.
Make the puzzle like the group of pictures that you’ve just seen, but make it harder to work out what the subject is.
