Skills and strategies used by teachers experienced in the art of teaching science seem so obvious to them that they go unnoticed and unreported, but they are not so obvious to science teachers at the start of their careers. The authors have made them explicit in a book packed with practical ideas and advice. The use of exposition, demonstration, practical work, investigation, simulation, discussion and independent learning are examined in detail through a wide variety of richly illustrated examples, together with reasons science teachers have for choosing one strategy rather than another. The examples are all real ones taken from recent classrooms, made more vivid by a large collection of photographs and sketches. The authors are all tutors at the University of London's Institute of Education with many year's experience of science teacher education.
