A Level OCR


Unit 10: Computational thinking

Component 02


This is a free unit (full price £140)


This unit is FREE. You can order it via our online ordering system. No purchase order number is necessary.

The unit is subdivided into six topics and an end-of-unit assessment. Each topic may be spread over more than one lesson, especially if time is spent in the lessons going over homework tasks.

It is a theoretical unit covering the OCR Computer Science specification Section 2.2.1 Elements of Computational Thinking and Section 2.2.2 Computational methods.  It describes what is meant by “computational thinking” in its many forms and is designed to develop this skill with the aid of many practical examples related to problem recognition and decomposition, abstraction and algorithm design.  It covers the topics of backtracking, data mining, heuristics, performance modelling, pipelining and visualisation.


What's included?

The A Level units have been written to satisfy the specification for Component 1 and Component 2 of the OCR H046/H446 Computer Science AS/A Level. Each unit contains:

  • PowerPoint slides for each topic
  • Detailed lesson plans
  • Learning objectives and outcomes
  • Worksheets and homework activities with answers
  • End-of-unit, exam-style assessment test with answers
  • Other material and links to online resources

What people say...

I relied heavily on your teaching materials for the AS Computer Science with AQA and I'm pleased to say the students did wonderfully well. Many of them got As, the lowest was a C and the residuals were the best in the school for an AS subject.

Paul Sloane. Head of Computer Science, Lady Manners School

Our pupils really enjoy the range of relevant topics, as well as the mixture of activities in each lesson. Needless to say, but we shan’t look anywhere else when it comes to resourcing the teaching of our future KS5 courses.

Bryan Owen. Computing Teacher, King Edmund School
