Computational thinking

Question 1

Computational Thinking is:

Answer 1

a way of thinking to solve problems and express the solutions in such a way that a computer carry them out

Question 2

algorithm is

Answer 2

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

Question 3

4 key computational thinking skills:

Answer 3

• Decomposition
• Pattern Recognition
• Abstraction
• Algorithm design

Question 4

Decomposition is

Answer 4

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

Question 5

pattern recognition is

Answer 5

You may spot similarities between the smaller problems.
These may help you find shortcuts or make useful predictions.

Question 6

abstraction is

Answer 6

To help us solve difficult problems, we ignore irrelevant detail.
By doing so, we can generalise our solution to solve other similar problems in future.
Another word for this is generalisation.

Question 7

Algorithm design is

Answer 7

when we 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.
