- To understand the purpose of computer parts
Pupils should be taught to:
- Design, write and debug programs that accomplish specific goals, including controlling or simulating physical systems; solve problems by decomposing them into smaller parts
- Use logical reasoning to explain how some simple algorithms work and to detect and correct errors in algorithms and programs
For pupils needing extra support: Use pictures such as those in the ‘Hello Ruby’ book to allow simpler identification of the parts of a computer.
Pupils working at greater depth: Should be encouraged to make links with the unplugged activity and the ‘real’ transition that takes place.
