Students are given one of the 26 different character cards ranging from Kaiser Wilhelm to Gavrilo Princip to lesser known players such as Leopold Lojka. Once students have got to know their character they then get into teams of fellow countrymen and attempt to find evidence to answer the question as to why the war began. There are 31 pieces of evidence for them to sift through, all greatly detailed and colour-coded for differentiation. This is one of the lessons I'm proudest of and it always leads to powerful debate and empowers students with extremely high levels of subject knowledge from which to begin extended written responses to one of the biggest questions in History. I hope you enjoy it as much as my students do.
