Pattern generalisation and abstraction
•
Ignoring - the characteristics that we don't need in order
to concentrate on those that we do.
If we have other animals that have the same
characteristics, we can simplify them with an
abstraction.
Abstraction
•
If you are learning to drive a car, you
concentrate on the function of the
steering wheel, accelerator, brakes
and so on
•
If you are learning to be a mechanic, you
will concentrate on how these
things actually work
Thinking abstractly
•
Abstraction typically involves:
•
devising a model that represents the reality – for example, think of a
simple queue, or something as complex as a climate change model
•
removing details that are not relevant to the problem
Activity
What details about a queue are irrelevant to figuring out
how many tills are needed in a new store?
Another queueing problem
•
Suppose you are trying to find a solution to the problem
of bottlenecks at toll booths on a motorway
•
What factors would be relevant, and what
would be irrelevant?

In computational thinking, recognizing patterns and abstraction play crucial roles. Generalization and abstraction involve focusing on essential characteristics, simplifying concepts for easier understanding. This process helps in problem-solving and decision-making by filtering out irrelevant details. Explore the concept of abstraction in various scenarios like driving a car or analyzing queueing problems, emphasizing the importance of devising models that represent reality. Enhance your understanding of abstraction's role in addressing bottlenecks and optimizing solutions in real-world situations.
