Computational Thinking Assessment #2

What chronological order does computational thinking occur?

• Abstraction, decomposition algorithm, pattern recognition

• Pattern recognition, decomposition, algorithm, evaluating solutions, abstraction

• Decomposition, pattern recognition, abstraction, algorithm

• Pattern recognition, algorithm, evaluating solutions, abstraction, decomposition

Abstraction is useful because it:

• Is a logical sequence of steps

• Filters out all of the irrelevant details or information, in order to concentrate on what is important

• Breaks down complex problems down into smaller, more manageable parts or tasks

• Looks for the similarities in the details or information given

Choose all that apply. Abstraction:

• Is a problem solving tool

• Adds important information

• Focuses on what is important

• Simplifies a situation

• Removes unimportant information

During the abstraction phase, you remove:

• General characteristics

• General and specific characteristics

• Specific characteristics

• None of these

Examples of specific characteristics are:

• This book was exciting

• Games are extremely relaxing

• My dog is friendly

• Those cars are multicoloured

Houses have walls, ceilings, doors and people live in them. They can be multiple levels. How many of these characteristics do architects need to know when drawing plans for a house?

• 2

• 3

• 4

• 5

You were given the following information to draw a cat unique to you:

black fur, eyes, small ears, a tail, fur, short legs, green eyes, striped fur, long tail

How many of the stated characteristics do you need to know?

• 2

• 4

• 6

• 8

When manufacturing vehicles, which of the following characteristics are vital information?

• the potential owners

• the amount of wheels

• the amount of people it seats

• who sells them

An example of general characteristics are:

• this book was exciting

• games are extremely relaxing

• those cars are multicoloured

• my dog is friendly

An algorithm is:

• The recipe for a cake

• Focusing on important parts and ignoring the irrelevant details

• The breaking down of a problem into smaller parts.

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