Computer Science KS4


The computer science course is designed to enable learners to:

  • Understand and apply the fundamental concepts of computer science, including abstraction, decomposition, logic, algorithms, and data representation.
  • Analyse problems in computational terms through practical experience of solving such problems, including designing, writing and debugging programs.
  • Think creatively, innovatively, analytically, logically and critically,
  • Understand the components that make up digital systems, and how they communicate with one another and with other systems.
  • Understand the impacts of digital technology to the individual and to wider society.
  • Apply mathematical skills relevant to computer science.
