This page has now been revised (May 2010) in the light of John Hattie's recent apparently definitive work Visible Learning; a synthesis of over 800 meta-analyses relating to achievement (London; Routledge, 2009). The first thing to change has been the title, which used to be "What works and what doesn't". Hattie points out that in education most things work, more or less. The questions are around those which work best and therefore best repay the effort invested. This site is mainly about your own individual practice as a teacher, and as such it tries to take into account your particular circumstances, such as the students you teach (assumed largely to be over school-age), your subject, your setting (school, college, university, work-based or informal adult education).
