Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
In this unit pupils will discover the computational thinking techniques; decomposition, abstraction and algorithmic thinking. They will reflect on differences between algorithms and computer programs and explore how algorithms can be represented. Pupils will explore the impact of algorithmic bias.
Lesson Summary
You will learn to create and represent an algorithm in a flowchart.
Key Notes
- Algorithms can be represented by flowcharts.
- Flowcharts use symbols to visually represent logic and data.
- Developing an algorithm's logic before coding makes problem solving easier.
Vocabulary To Learn
- flowchart: a visual representation of an algorithm or program
- symbol: a sign, shape or object that is used to represent something else
- standardise: to make one thing the same as others of that type
Common Mistakes To Avoid
- A flowchart should always be created before writing a computer program.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Algorithms can be represented by flowcharts. Flowcharts use symbols to visually represent logic and data.
2. Define this computing term and give one practical example. 'flowchart'
a visual representation of an algorithm or program. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: A flowchart should always be created before writing a computer program. Correction: For simple programs, a flowchart may not be needed and could add to development time. Sometimes the program code itself might be clear enough without a flowchart.
