their creativity and imagination. Adults can either add "philosophical questions" to "classic" stories and fairy tales themselves, or use special children's books for discussing philosophy with children. Michael Siegmund recommends stories in which animals are the main characters and child-friendly questions are asked. Possible topics may include poverty and wealth, friendship and family, happiness, freedom, environmental pollution, justice, and more. Diversity in the United Kingdom There is particular diversity in the UK, owing to the large number of competing and collaborating freelance trainers each emphasising different strands of the pedagogy. Roger Sutcliffe's practice includes the use of news stories; Steve Williams has emphasised the importance of dialogues that model argument as well as raising philosophical issues; Will Ord emphasises the use of striking photos, often containing contrasts that suggest opposing concepts; Jason Buckley advocates a more physical, game-based approach and "Philosophy in Role", in which children philosophise within a story as characters confronted with a variety of problems. SAPERE is the UK's leading provider of P4C training. Registered in 1994, the charity has trained over 27,000 teachers and other individuals in the use of P4C. SAPERE's mission is to advance the educational, personal, and social development of young people, especially those facing disadvantage, through the promotion of P4C. The organisation's work gained national prominence in 2015 when Durham University School of Education published results of a randomised control trial of P4C with over 3,000 primary school students. The study was sponsored by the Education Endowment Foundation. The limited study found that P4C advanced attainment for all students and had a particularly strong impact on children from disadvantaged backgrounds. A larger later study showed little attainment advancement in the classroom context. Co-founded by Peter Worley and Emma Worley, The Philosophy Foundation's specialist philosophy teachers (all philosophy graduates) specifically use philosophical material, including thought-experiments and stories or activities that lead to questions from the philosophical canon. They make use of carefully structured questioning strategies and also the introduction of thinking skills in order to develop good thinking habits from a young age. The questioning strategies are used to introduce dialectic along Platonic lines and in order to maintain philosophical focus. Uniquely they have a methodology that introduces writing and meta-analysis with older primary and secondary students.
