Computational Thinking Review

What is computational thinking?

• It allows you to break down a large / complex problem into smaller manageable parts.

• It is thinking like a robot

• It is being able to bake a cake.

• It is creating a coding solution to a problem.

What chronological order does computational thinking occur?

• Abstraction, decomposition algorithm, pattern recognition

• Decomposition, pattern recognition, abstraction, algorithm, evaluating solutions

• Pattern recognition, decomposition, evaluating solutions abstraction, algorithm

• Patterns, shapes, numbers, puzzles

What is abstraction?

• A painting
• A programming language
• This means focusing on the important details and ignoring the irrelevant information
• Abstraction is the breaking down of a big problem into smaller parts.

What does decomposition mean?

• focuses on the important information only, ignoring irrelevant detail
• Step by step instructions on solving a problem.
• Thinking like a computer
• This is the breaking down of a complex problem into smaller parts

What is an algorithm?

• The recipe for a cake

• The breaking down of a problem into smaller parts.

• Focusing on important parts and ignoring the irrelevant details

• an unambiguous, finite, logical sequence of step by step instructions used to solve a problem or accomplish a task

What are the two main ways that we represent an algorithm?

• By drawing pictures 
• Using flowcharts and pseudo code
• Using python and small basic
• Using Scratch and python

What is a flowchart?

• A pictorial representation of an algorithm using symbols

• Using 'fake code' to plan an algorithm

• Using a programming language to show an algorithm

• Uisng different types of charts to show an algorithm

What does the following symbol represent in a flowchart?

• An input

• Start

• End

• A process

What does the following flowchart symbol represent?

• A process
• An output
• A decision (choice)
• End

What does the following flowchart symbol represent?

• Input / Output
• Start of flowchart
• A process
• End
