Pupils should be taught to:
- Understand computer networks including the internet; how they can provide multiple services, such as the world-wide web, and the opportunities they offer for communication and collaboration
Pupils needing extra support: Work in partners and observe the more able partner. Then switch after the more able partner has completed, enabling the less able partner to understand what is required of them.
Pupils working at greater depth: Should experiment with the possibilities of the style of presentation and use Excel to help them to calculate exactly how many bits there are in each version of the image.
