Decomposition

What is decomposition?

• Adding detail to make a problem more complex

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

• When you ignore the unnecessary detail in a problem

• Recognising patterns in problems

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

• Creating a step-by-step plan to fix the car

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

• Only in the morning, when getting ready for the day

Which of these is NOT an example of decomposition?

• Thinking about how the problem could be divided into smaller parts

• Adding more parts to the problem so it becomes more complex

• Working out who could help you solve a part of the problem

• Arranging the problem so that you can prioritise it's components

I'm stuck on a question for my homework task due next week. Would I?

• Wait until the day before to finish it, I'll be older and wiser by then

• Not do the question, I can't get it

• Ask a friend who is in the same class to help me during break tomorrow

Which of these is an example of decomposition when solving a complex crime

• Analysing data to find patterns so that a criminal's habits can be tracked

• Looking at similar crimes in the area to find important information that could link the crimes

• Breaking down the complex crime into categories and locations, then deploying resources accordingly

• Creating a step-by-step plan of action for solving the complex in a well organised, efficient manor

Why do we need to think computationally? (multiple answers)

• To help us think like a computer

• To help us solve problems efficiently

• To help us solve problems slowly

• To help us solve complex problems easily

Which of these is not a computational thinking technique?

• Abstraction

• Decomposition

• Coding

• Algorithms

• Pattern Recognition
