Sue Dove describes a short but action-packed activity sequence that was designed explicitly to show the OFSTED inspector the impact of the department's professional thinking and long-term planning. An integrated approach to thinking and writing at Key Stage 3 and much training of pupils to adopt a disciplined and creative approach to historical debate, bears fruit at GCSE, especially in tricky topics. Sue Dove outlines her department's rationale for a Year 10 activity sequence on the League of Nations that left the OFSTED inspector (and the pupils) suitably impressed.
