Jim Green, Consett Academy
Look in any computing textbooks aimed at Key Stages 3 and 4 and you will probably find an illustration of a computer in terms of a simple Input / Process / Output model. This is very helpful for abstracting away much of the technical detail of a particular device, and is a useful starting point for children to consider what a computer does. All computers ‘compute’ but for curious children this simple model simply begs new questions. What is a computation? How might it be represented? Computer scientists have developed models that tackle these questions. Finite-state machines are one way to represent the steps involved in a particular process.
