This carefully planned course gives students a real, in-depth understanding of how computer technology works. It offers an insight into what goes on ‘behind the scenes’, including computer programming, which many students find absorbing.
Through this qualification students will:
- Develop their understanding of current and emerging technologies and how they work
- Look at the use of algorithms in computer programs
- Become independent and discerning users of IT
- Acquire and apply creative and technical skills, knowledge and understanding of IT in a range of contexts
- Develop computer programs to solve problems
- Evaluate the effectiveness of computer programs/ solutions and the impact of computer technology in society.
Here’s a summary of the course details and the Assessment Objectives for GCSE Computing:
Unit 451: Computer systems and programming
This unit covers the body of knowledge about computer systems on which the examination will be based
1 hour 30 minutes
80 marks 40%
Unit A452: Practical investigation
An investigative computing task, chosen from a list provided by OCR, Controlled assessment which assesses the following: research, technical understanding, analysis of problem, historical perspective, use of technical writing skills, recommendations/evaluation.
OCR-set scenario with a choice of research tasks
45 marks 30%
Unit A453: Programming project
Students will need to:
- understand standard programming techniques
- be able to design a coded solution to a problem
including the ability to:
- develop suitable algorithms
- design suitable input and output formats
- identify suitable variables and structures
- identify test procedures
- create a coded solution fully annotating the developed code to explain its function
- test their solution:
- to show functionality
- to show how it matches the design criteria
- identifying successes and any limitations
Controlled assessment programming task. Design, develop and test a solution to a problem within the OCR-set scenario.
45 marks 30%
Students are expected to demonstrate the following:
- AO1 Recall, select and communicate their knowledge and understanding of computer technology
- AO2 Apply knowledge, understanding and skills to solve problems by using computer programs
- AO3 Analyse and evaluate, make reasoned judgements and present conclusions.
