Computational Thinking Quiz

What is computational thinking?

• A) A way to communicate directly with computers

• B) A process that includes logically ordering and analyzing data to create solutions

• C) A method for improving computer performance

• D) A programming language for solving mathematical problems

How does computational thinking differ from programming?

• A) Programming is about fixing computers, while computational thinking is about using them.

• B) Programming tells a computer what to do and how to do it, while computational thinking helps you work out what to tell the computer to do.

• C) Computational thinking is a type of programming language, while programming is the process of writing code.

• D) Programming helps in creating algorithms, while computational thinking is about following instructions.

Which of the following is NOT one of the four elements to computational thinking?

• A) Decomposition

• B) Pattern recognition

• C) Data analysis

• D) Algorithm design

What does problem decomposition involve?

• Combining complex problems into a larger one

• Breaking a large, complex problem into smaller, simpler ones

• Solving problems without breaking them down

• Identifying similarities among problems

What is pattern recognition in problem-solving?

• Creating a sequence of steps to solve a problem

• Breaking down problems into smaller parts

• Identifying similarities among problems

• Focusing on the less important aspects of a problem

What is abstraction in problem-solving?

• Writing an algorithm in pseudocode

• Drawing a flowchart

• Differentiating between important and less important aspects of a problem

• Combining solutions to create a larger solution

What is an algorithm?

• A flowchart that represents data flow

• A diagram that visualizes a problem

• A sequence of steps designed to solve a particular problem

• A method to identify patterns in data

How can an algorithm be expressed?

• In a detailed report

• As a series of images

• In a stylised form of English called pseudocode

• Through a series of mathematical equations

What is the purpose of a flowchart in problem-solving?

• To create a sequence of steps in pseudocode

• To represent an algorithm and demonstrate the flow of data in a solution

• To break down a problem into smaller parts

• To identify the less important aspects of a problem

What is the purpose of the Start/Stop symbol in a flowchart?

• To show data being inputted or outputted

• To indicate a decision point that can be yes or no

• To mark the beginning and end points in the sequence

• To represent a jump from one point in the sequence to another
