What will the world economy look like 30 years from now? And how should we be preparing British schoolchildren today to find employment in it? Robert Peston travels to four cutting edge schools that claim to provide the way forwards for secondary education.

Should the focus be on languages and cultural knowhow for an increasingly globalised world? Should we be striving to create more of the engineers and programmers that so many employers are crying out for? Or - with the unstoppable march of the robots gobbling up ever more human jobs - should we be preparing kids with the social skills to be future entrepreneurs, employing their own personal fleets of automatons? Or is a traditional academic education the answer.

Robert Peston tries to get answers to perhaps the most important question all parents must ask from economists, scientists and teachers - and argues that what matters may not be the detail of the curriculum but the way children are taught to learn.
