  1. GCSE Computing Taster Day Session 2014 Mrs Dearing

  2. What is the course about? • This specification encourages you to acquire and apply creative and technical skills, knowledge and understanding of IT in a range of contexts. • You will look at the use of algorithms in computer programs, develop computer programs to solve problems as well as evaluating the effectiveness of solution and the impact of computer technology in society.

  3. How is the course made up? The OCR Computing course has three units. • Unit 1 is a written examination worth 40% for the overall qualification which you will take in the summer of Year 11. You will cover the theory required for the examination across the two years. • Unit 2 and Unit 3 are controlled assessment units worth 60% of the overall qualification. The controlled assessment tasks are set by the exam board

  4. Theory ContentUnit A451: Computer systems and programming • Fundamentals of computer systems • Computing hardware • Software • Representation of data in computer systems • Databases • Computer communications and networking • Programming

  5. Unit A452: Practical Investigation Controlled Assessment (30%) An investigative computing task, chosen from a list provided by OCR, which assesses the following: • Research • Technical understanding • Analysis of problem, • Historical perspective, • Use of technical writing skills, • Recommendations/evaluation

  6. Unit A453: Programming Project Controlled Assessment (30%) You will create solutions to three computing tasks from a set of options supplied by OCR • Design a coded solution to a problem • Create a coded solution annotating the code to explain its function • Test your solution • Identify successes and any limitations

  7. Open up Python IDLEStart > Python >Python IDLE

  8. Type 2+2 and press enter • Python uses the same characters you are familiar with in spreadsheets • Have a go at Task 1 on the sheet

  9. Variables • You can create variables and then use them in your program • Follow the instructions for task 2 on the sheet

  10. Accepting inputs • You can interact with your program using the input command • Have a go at Task 3 on the sheet

  11. Magic 8 Ball Task • Have a go at program 4 on the task sheet. • It shows you how to create your own magic 8 ball program. • It uses variables, while statements, else if and inputs

  12. Useful Websites • The websites below are free to join and allow you to teach yourself several different programming languages. • www.codeacademy.com • www.codeavengers.com • Check them out
