What did they learn?

The final task that the students had to do was to think of three reasons why they think that one person could change the world and three reasons why they think someone couldn't and then to decide for themselves.
Some coped with it well and others found it extremely difficult to think from another point of view and give both sides to an argument. With more time it would have been great to have a socratic discussion but with only one period it's difficult to find the time.

It's something more to think about and something that I would like to try again with another group of students.
