This video clip from the ABC’s MediaWatch program (Episode 32, 10 September 2012 ) shows how Dr Taneer Ahmed has been caught out plagiarizing other people’s work and pretending it’s his own – a foolish move in the digital age when it’s so easy to track copying. This is a good clip to show senior students.
