At the end of this unit
most pupils will: write a sequence of instructions that control events and understand that the order in which instructions are executed is important; explore the effects of changing variables in an ICT-based model; discuss the use of ICT outside school and make judgements about its use in their work
some pupils will not have made so much progress and will: write a solution that will raise and lower the barrier by giving instructions in a predetermined sequence; compare the use of ICT with other methods and how it is used outside school
some pupils will have progressed further and will: refine the instructions within a program so that they are carried out efficiently and economically; make judgements about their overall project and understand the areas that need to be developed after applying criteria they have identified; demonstrate a deeper understanding of how such developments have implications for society
