Zobel and Hamilton (2002) argue that too often students are being asked to do a task that a lot of other students have already done. Maximising variation in assignments limits the scope for copying. Some suggestions are to:
– vary assignments each year
– have multiple assessment tasks
– relate assessment to individual life circumstances and experiences
– ask for explanatory information where there is only small scope for variation
– view draft material
– set assessment tasks that use material that cannot be easily copied.
