The study of conceptual change traces its heritage to the notions of paradigm (networks of shared beliefs, concepts, practices) and paradigm shift made famous by Thomas Kuhn in his book, The Structure of Scientific Revolutions . Kuhn’s work was quickly linked to developmental psychology (how knowledge develops) and to science education (teaching big, new ideas). This book is the first comprehensive review of the conceptual change movement and of the impressive research it has spawned on how knowledge develops and can be taught in different content areas. Because of its interdisciplinary focus chapter authors were instructed to write in a manner comprehensible to researchers and students from different fields.
