Sixth Form

A Level Computer Science

Computer Science (OCR H446)

Computer Science is not the same as ICT! At the heart of Computer Science is the development of computational thinking, helping learners to develop the skills to solve problems, design systems and understand the power and limits of human and machine intelligence. It is a practical subject where learners can apply the academic principles learned in the classroom to real world systems. It is an intensely creative subject that combines invention and excitement, and can look at the natural world through a digital prism. It is also an academically rigorous subject where learners will develop an ability to analyse, critically evaluate and make decisions. Throughout this new course there will be an emphasis on problem solving using computers, computer programming and algorithms, and the mathematical skills such as Boolean algebra used to express computational laws and processes.

Although this is a new syllabus, we are not a new department and have been successfully delivering Computing to A level standard for well over 15 years. The new syllabus has removed much of the older “ICT” content and instead has been updated to reflect changes in computing and web technologies. No prior experience of Computing is required, although we would expect students to have achieved at least a grade B in Mathematics at GCSE level. However, a passion for computing is much more important and we would be delighted to consider any student who is fascinated by computer technology and is willing to work hard and try their very best.

The OCR H446 Computer Science A Level syllabus has been designed to be co-teachable with the stand-alone Computer Science AS Level (H046). Therefore, in line with many other departments at Birkdale, all students on this course will follow the same linear route of progression throughout the course; all Lower Sixth Computer Science students will sit the AS public examination in the summer term, and can then choose to continue Computer Science in the Upper Sixth to complete the A Level.

A Level Computer Science

Paper 1: Computer Systems (Written paper 2 ½ hrs - 40% of A Level)
This component contains the majority of the content of the qualification and is assessed in a written paper recalling knowledge and understanding.
Topics of Study include: Components of a computer and their uses; Software and software development; How data is exchanged between different systems; How data is represented and stored within different structures; Different algorithms that can be applied to these structures; The individual (moral), social (ethical) and cultural opportunities and risks of digital technology; Legislation surrounding the use of computers and ethical issues that can or may in the future arise from the use of computers.

Paper 2: Algorithms and Programming (Written paper 2 ½ hrs  - 40% of A Level)
This component relates principally to problem solving skills needed by learners to apply the knowledge and understanding gained in the first component.
Topics of Study include: Understand what is meant by computational thinking; How computers can be used to solve problems and programs can be written to solve them; The use of algorithms to describe problems and standard algorithms.

Component 3: Programming Project (Non-exam teacher assessment – 20% of A Level)
The project is a substantial piece of work which assesses a variety of different skills including the development and demonstration of computational thought processes. Learners will need to choose, in liaison with their teacher, a well-defined user driven problem. The choice of project must enable learners to: meet all assessment requirements as contained in the specification; use an appropriate programming language which is non-trivial and has a substantial coded element; solve a problem sensibly within the constraints of resources available facilitate the successful completion of a whole task from its definition to its acceptance and evaluation by that user. The project will be submitted in the form of a report that will contain the solution the chosen task.

Please note: Mathematical skills are embedded throughout the content of the three components. They will be assessed in the written papers and through the non-examined assessment where appropriate.

Student views on the course
On completion of Computer Science courses most students look back on a challenging but very rewarding achievement. They feel that the skills they learn will be good preparation for future study and vocational responsibility. Some have maintained an interest in programming and database development, and have found useful applications later on in their careers.
