Computer Science

Specification EDEXCEL

Why study Computer Science?

Computer Science is relevant to the modern and changing world of computing. The new specification will allow you to:

  • Focus on programming, building on GCSE Computing and emphasise the importance of computational thinking as a discipline.
  • Have an expanded maths focus, much of which will be embedded within the course.
  • Put computational thinking at its core, helping you to develop skills to solve problems, design systems and understand human and machine intelligence.
  • Allow you to apply the academic principles learned in the classroom to real world systems in an exciting and engaging manner.
  • Give you a clear progression into higher education, as the course was designed after consultation with members of BCS, CAS and top universities.

What will I study?

Computer Science is a practical subject where students can apply the academic principles learned in the classroom to real-world systems. It’s an intensely creative subject that combines invention and excitement, and can look at the natural world through a digital prism. The aims of this qualification are to enable learners to develop:

  • An understanding and ability to apply the fundamental principles and concepts of computer science, including: abstraction, decomposition, logic, algorithms and data representation.
  • The ability to analyse problems in computational terms through practical experience of solving such problems, including writing programs to do so
  • The capacity to think creatively, innovatively, analytically, logically and critically
  • The capacity to see relationships between different aspects of computer science
  • Mathematical skills.

 

The key features of this specification encourage:

Emphasis on problem solving using computers

Emphasis on computer programming and algorithms

Emphasis on the mathematical skills used to express computational laws and processes, e.g. Boolean algebra/logic and comparison of the complexity of algorithms

Less emphasis on ICT.
