WHY COMPUTER SCIENCE?
The Computer Science syllabus allows students to develop their understanding of the main principles of problem-solving using computers.
Students can apply this understanding to develop computer-based solutions to problems using algorithms and a high-level programming language.
Students will also develop a range of technical skills, as well as being able to effectively test and evaluate computing solutions. Studying the course will enable students to appreciate current and emerging computing technologies, the benefits of their use and recognise the potential risks.
SYLLABUS CONTENT:
The aims are to:
• understand and apply the fundamental principles and 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.
ASSESSMENT:
OCR’s Computer Science qualification consists of two compulsory components that are externally assessed. Both papers have identical weighting and mark allocations:
01: Computer Systems – written paper, 1hour 30 minutes, 50% of total GCSE, 80 marks.
The question paper will consist of short and medium answer questions. There will also be one 8-mark extended response question. This question will enable students to demonstrate the ability to construct and develop a sustained line of reasoning.
02: Computational thinking, algorithms and programming –written paper, 1hour 30 minutes, 50% of total GCSE, 80 marks.
The question paper will consist of short and medium answer questions.
Practical Programming - you will be given the opportunity to undertake programming tasks, either to a specification or to solve a problem (or problems), during the course of study.
