This course book follows an approach that supports the new 2007 syllabus (to be first examined in 2009) while including the wider aims of the IB through connections to TOK, international-mindedness and the IB learner profile. It has been written by a former chief examiner for IB Diploma Programme Biology and has been extensively reviewed by teachers, consultants and the IB. With features and activities that encourage active learning and critical thinking, students will find this book stimulating and engaging.
