9.2 CS Computational Think 1

What do we mean by COMPUTATIONAL THINKING?

• Understanding a complex problem and developing possible solutions.

• Breaking a task into smaller tasks.

• Selecting a computer to use.

• Focusing on what is important, ignoring what is unnecessary.

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

Why do we need to think computationally?

• To help us program
• To help us solve complex problems more easily
• To help us to think like a computer

Breaking down a complex problem or system into smaller or more manageable parts.

• decomposition
• pattern recognition
• abstraction
• algorithms

Which of the following is NOT computational thinking?

• decomposition
• coding
• pattern recognition
• algorithms

What is a complex problem?
A problem that, at first, is...

• not easy to solve
• is not easy to understand
• is not easy to understand or solve
• cannot be solved

When is a computer most likely to be used when using computational thinking?

• during decomposition
• at the end, when programming a computer
• when writing algorithms
• when working on abstraction

Why do we decompose a complex problem?

• To make it easier to solve

• To make it more difficult to solve

• To change the problem we have

Which of these is an example of decomposition?

• Watching a mechanic repair a car

• Finding out how a car works by looking in detail at the different parts that make up the car

• Looking at different car models for similarities between them

How often do we decompose problems?

• We never decompose them, computers do this for us

• Occasionally, but we don't really need to

• Every day, often without thinking about it
