The Head of History at Cromwell Community College in Cambridgeshire has devised a Big Idea that has successfully raised the attainment levels of lower ability pupils at Key Stage 3.

Hannah Dalton challenges the pupils' thinking and sparks a debate by putting forward an incorrect or overly simplistic view on the subject they're discussing. Using character cards to help the Year 7 students identify with real people from the past, they work in small groups and set out to attack their teacher's argument.

In this programme, the staff at Cromwell Community College share their top tips for helping children grasp important concepts, teaching them to explore at a deeper level, and enabling pupils to articulate their ideas - all of which are transferable to all aspects of the curriculum.
