In Chicago, pupils learnt the story of making clothes which combined economics, story-writing and dance. They were introduced to modern dance as they acted out the roles of the different occupations involved.
A storyline they devised then brought in the economics of production - a mistake in the design process meant that the clothes were only available in large sizes, and sales plummeted.
Another lesson involved the dramatisation of biological terms: drama teachers helped to act out the structure of a cell and a biological classification of plants and animals.
At the same time, pupils learnt to conquer their nervousness when speaking in public.
