Educators and the education policy community will be familiar with his work on topics including homework, extra-curricular activities, remediation in higher education, and the impact of part-time jobs on academic achievement. His new book, Age of Opportunity, mines his own research and that of others from the fields of psychology, sociology, history, education, medicine, law, criminology, public health, and neuroscience to provide “lessons from the new science of adolescence.” His purpose, as he puts it, is to help people “parent more intelligently” and “teach more effectively.”
