In equal parts a fascinating history of assessment and a concrete call for action. Professor Wassermann empowers readers to reflect on their own approach to evaluation and confront biases, preconceptions and challenges, taking the reader beyond already well-trodden themes of basic weaknesses in the methods and our “love affair” with numbers. Key distinctions are made between enabling or disabling feedback, complemented by a wealth of examples and specific feedback. Wassermann suggests approaches that can be adopted even when teachers are faced with pressure to conform to traditional measures from administration, parents and even students themselves.
