KS3 Computer Science

Computer Science is a very fast changing discipline. Our intention is to prepare pupils to know today’s technology and today’s programming styles, but in particular to learn for tomorrow’s technology. Computing reaches all sectors of society and as Bristol has a vibrant creative sector, it is important that this is reflected in students’ learning.

As our Computer Scientists move through the curriculum they will focus on the following threads that run through each year and each unit:

  • Online safety
  • Programming structures
  • Problem solving
  • Computational thinking

Interactive Multimedia Project 

This is a project designed to develop a range of skills; planning, researching, designing, creating and  evaluating. It will be based around a scenario and will involve how to use the Internet effectively to  find information, including how to spot bias. The finished product will be an online brochure  comprising text, graphics and video.
