OCR GCSE (J277) Computer Science - 'Technical Topics' PowerPoints & Worksheets

Animated PowerPoint presentations and follow-up worksheets designed to reinforce the mathematical and logical concepts of the OCR GCSE (J277) specification.

Fantastic for encouraging independent work. Students can use the slides provided and complete the worksheets at their own pace

R Walker, 2nd in Dept, Customer

An invaluable resource which enables all students to grasp the fundamentals of algorithms, programming, number bases and data representation.

  • 19 animated PowerPoints providing step-by-steps of important concepts. Perfect for teacher-led classroom learning (and great for visual learners!)
    Also provided in HTML5 (for web browsers/mobile devices), as well as PDF (for producing printed handouts)
  • Supporting worksheets test students’ understanding and application of concepts covered in the PowerPoints
  • Interactive practice for calculation/conversion topics
  • Use in class or for homework; to support teaching and revision.
  • Includes easy answers for self/peer or teacher marking.

What do teachers say about this resource? (10595)

Helpful and well designed to support learning. It makes effective use of animated PowerPoint presentations and follow-up worksheets that are clearly aligned with the mathematical and logical concepts of the OCR GCSE (J277) specification ... the PowerPoint presentations were clear, engaging, and easy to follow. The animations and accompanying worksheets were particularly effective in reinforcing key ideas and supporting understanding ... I particularly liked the animated PowerPoint presentations, especially the more hands-on elements such as those in Slide 2, which helped make the concepts easier to understand and more engaging. The worksheets were also useful for reinforcing learning ... This resource enhances learning by presenting mathematical and logical concepts in a clear and engaging way through animated PowerPoint presentations. The step-by-step explanations and hands-on elements help learners to visualise abstract ideas and build understanding gradually ... some nice clear examples for computing teachers and non-specialists too

L Hayes, Lecturer & Peer Reviewer

The resources provided were comprehensive, particularly the online practice worksheets covering binary and algorithms. These will be valuable for students focusing on the practical aspects of Computer Science, as they offer a hands-on approach to understanding these essential topics ... These practical worksheets provide an excellent starting point for students to grasp the fundamentals of Boolean logic and gates ... a good foundation on computer science topics
