Learning

The A-level specification in computer science contains both theory and practical elements. The theory elements will enable students to develop an understanding of:

  • The characteristics of contemporary processors
  • Input, output and storage devices
  • Software and software development
  • Exchanging data
  • Data types, data structures and algorithms
  • Legal, moral, cultural and ethical issues
  • Elements of computational thinking
  • Problem solving and programming
  • Algorithms to solve problems and standard algorithms. 

Students will choose a computing problem to work through according to the guidance in the specification.

  • Analysis of the problem
  • Design of the solution
  • Developing the solution
  • Evaluation
