1. Computational thinking

Question 1

Definition of Computational Thinking

Answer 1

A way of thinking to understand and solve a complex problem, and present the solutions in such a way that a computer carries them out

Question 2

Definition of Algorithms

Answer 2

A step-by-step set of instructions that represents the solution to a problem

Question 3

The 4 key computational thinking skills

Answer 3

Decomposition, Pattern Recognition, Abstraction and Algorithm design

Question 4

Definition of Decomposition

Answer 4

Break big, difficult problems down into a series of smaller, easier problems.

Question 5

Definition of Pattern Recognition

Answer 5

Spot similarities between the smaller problems/different complex problems to find shortcuts or make useful predictions.

Question 6

Definition of Abstraction

Answer 6

Ignore irrelevant detail and generalise our solution to solve other similar problems in future.

Question 7

Definition of Algorithm design

Answer 7

Convert our solution into a sequence of precise, step-by-step instructions that a computer or other people can use to solve the same problem.

Question 8

Give an example of abstraction

Answer 8

To draw a cat, you ignore its name and its favourite food.

Question 9

Give an example of decomposition

Answer 9

Revise for your exam by dividing subjects into different topics.

Question 10

Give an example of pattern recognition

Answer 10

You can draw a cat by recognising that all cats have eyes, fur and a tail.
