Flashcards
Decomposition
Decomposition
Breaking down a complex problem into smaller, more manageable parts.
Pattern Recognition
Pattern Recognition
Identifying common characteristics among different problems or within a single complex problem to simplify problem-solving.
Brushing Teeth (Decomposed)
Brushing Teeth (Decomposed)
Breaking down a task into smaller parts such as applying toothpaste, wetting the brush, and brushing each section of your teeth.
Study Notes
Computational Thinking: Decomposition and Pattern Recognition
- Computational thinking is a problem-solving process that involves four key strands: abstraction, decomposition, data modelling, pattern recognition, and algorithmic thinking.
- Decomposition involves breaking down a complex problem or system into smaller parts that are more manageable and easier to understand.
- Decomposition is important because it makes a problem easier to solve by allowing it to be examined in more detail.
- Patterns are similarities or characteristics that some of the problems share, and pattern recognition is important in finding these similarities.
- Pattern recognition is one of the four cornerstones of Computer Science.
- Finding patterns makes problem-solving simpler and quicker.
- If we don't look for patterns, it can slow us down and lead to solving problems incorrectly.
- Brushing our teeth is an example of a task that can be decomposed into smaller parts, such as which toothbrush to use or how long to brush for.
- Solving a crime is an example of a complex problem that can be decomposed into smaller problems, such as what crime was committed or if there were any witnesses.
- When we decompose a complex problem, we often find patterns among the smaller problems we create.
- Knowing how to describe one cat allows us to describe others simply by following a pattern, such as having eyes, tails, and fur.
- Finding patterns is extremely important because the more patterns we can find, the easier and quicker our overall task of problem-solving will be.
