Year 11 - Computing

Project design

Python programming project

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 create a structured design for a programming project.

Key Notes

  • Structured design is the process of planning a program in detail before you start to write any code.
  • This design stage is essential for developers to understand the program's requirements and how it will function.
  • Tools like flowcharts provide a visual representation of a program's logic.
  • Pseudocode offers a text-based, step-by-step description of a program's operation.
  • Designing a program this way helps to prevent mistakes, saves time and makes final code easier to write and understand.

Vocabulary To Learn

  • flowchart: a diagram that uses symbols to document the logic of an algorithm
  • pseudocode: a way of expressing an algorithm that is independent of a specific programming language

Common Mistakes To Avoid

  • Pseudocode can be executed by a computer.

3 Quick Questions (With Answers)

1. Describe the system or process from this lesson in clear steps.

Structured design is the process of planning a program in detail before you start to write any code. This design stage is essential for developers to understand the program's requirements and how it will function.

2. Define this computing term and give one practical example. 'flowchart'

a diagram that uses symbols to document the logic of an algorithm. Add one real device or system example to prove understanding.

3. Correct this common computing misconception.

Mistake: Pseudocode can be executed by a computer. Correction: Pseudocode cannot be executed by a computer. Pseudocode must be translated into a real programming language such as Python, Java or C# for it to be executed by a computer.
