Lesson details

Key learning points

  1. When approaching a programming project there will be a set of requirements that the program must solve or meet.
  2. When approaching a programming project it is useful to follow the software development life cycle.
  3. When designing a program it is useful to develop pseudocode before creating the actual program code.

Keywords

  • Pseudocode - a way of expressing an algorithm that is independent of a specific programming language

  • Software development cycle - defines the main stages of software development

Common misconception

Pseudocode is the same as a programming language and must follow a particular syntax.

Pseudocode is independent of a specific programming language and does not need to follow any particular rules. All that is required is that a programmer can read the pseudocode and understand how to implement it.


To help you plan your year 10 computer science lesson on: Programming project: selection I, download all teaching resources for free and adapt to suit your pupils' needs...

This is the first lesson of two project lessons which can be used to give pupils the opportunity to apply their understanding of the programming concept selection. It would be advisible if pupils have covered selection before attempting this project.
