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 have the opportunity to apply the skills and knowledge they have developed in previous programming units by approaching a practical project. They will apply software design, product design and testing principles to take their project from initial design to working prototype.
Lesson Summary
You will learn to define and explain key software design principles.
Key Notes
- Software design principles are guidelines that help developers write clean, efficient and maintainable code.
- Good design makes code easier to read, test and change.
Vocabulary To Learn
- modularity: breaking software into independent, self-contained units or modules
- abstraction: focusing on the important parts of a problem and ignoring irrelevant detail
- readability: how easily someone can understand your code
- maintainability: making software easy to change, fix or update later on
Common Mistakes To Avoid
- If you are developing code for a project on your own, you don't need to worry about software design principles.
3 Quick Questions (With Answers)
1. Describe the system or process from this lesson in clear steps.
Software design principles are guidelines that help developers write clean, efficient and maintainable code. Good design makes code easier to read, test and change.
2. Define this computing term and give one practical example. 'modularity'
breaking software into independent, self-contained units or modules. Add one real device or system example to prove understanding.
3. Correct this common computing misconception.
Mistake: If you are developing code for a project on your own, you don't need to worry about software design principles. Correction: Even if your code isn't used by others, it is a good idea to follow software design principles in case you have to revisit or develop your code later on.
