COMPUTER SCIENCE  
INTRODUCTION

Computer science is an extraordinarily creative enterprise. It has changed the way we live, has propelled our economy forward through innovation and will continue to do so for the foreseeable future.

Still, it might not be clear what “computer science” is. Perhaps a better term for what we study is “computational thinking”. Computational thinking primarily emphasizes that we are interested in problem solving with computers. This problem solving can be viewed from many angles: logic, algorithms, abstraction, and computability. Study a subject that introduces trending new tools, platforms, requirements and API’s - that’s the beauty of technology. Just smile and face them as new challenges.

CONTENT
UNIT: 1

In this unit we will introduce learners to the Central Processing Unit, computer memory and storage, wired and wireless networks, network topologies, system security and system software.  It is expected that learners will become familiar with the impact of Computer Science in a global context through the study of the ethical, legal, cultural and environmental concerns associated with Computer Science. It is expected that learners will draw on this underpinning content when completing the Programming Project component.

UNIT: 2 This unit incorporates and builds on the knowledge and understanding gained in Component 01, encouraging learners to apply this knowledge and understanding using computational thinking. Learners will be introduced to algorithms and programming, learning about programming techniques, how to produce robust programs, computational logic, translators and facilities of computing languages and data representation. Learners will become familiar with Computing related maths.
UNIT: 3 OCR will issue three assessment tasks. The tasks will provide opportunities for the learners to demonstrate their practical ability in the skills outlined in the specification. Learners will be encouraged to be innovative and creative in how they approach solving the tasks.  A total of 20 hours will be allocated to complete the tasks under teacher supervision and the learner must use a suitable high level programming language. In this unit learners must think computationally to solve a task and while doing so create a report detailing the creation of their solution, explaining what they did and why they did it.
ADDITIONAL INFORMATION

Learners take components: 01, 02 and 03 or 01, 02 and 04 to be awarded the OCR GCSE (9-1) in Computer Science.
