The International Baccalaureate (IB) is a respected qualification gaining increasing currency around the world, and which has been adopted by a wide variety of schools, both public and private. In the UK, growing dissatisfaction with the A-level system has led to an intense debate about alternative qualifications, and in many schools IB courses have been introduced alongside conventional A-level courses.This practical introduction to the IB takes a balanced look at the pros and cons and features a wealth of advice from those actually involved in teaching and implementing it in schools. Providing comparative material on how IB courses differ from A-levels and a subject-by-subject account of best practice in teaching the IB, this book offers a rich source of practical advice for teachers, school leaders or managers involved in teaching or implementing the IB programmes.
