These days, when many young people have out-of-school access to computing and the web, where they are contributing to writing websites, mashing videos, setting up websites to sell stuff and even creating mobile phone apps in their spare time, it’s verging on insult to set them work that is not authentic. Tell them to pretend that their friend has asked them for advice on setting up a travel agency (I have actually seen that in an examination paper; the only sensible answer is “Do some proper research on the ins and outs of setting up a travel agency.”), and they know they are not getting the real deal.
