Under-Education in Africa: From Colonialism to Neoliberalism is a collection of essays on diverse aspects of educational systems that were written over a period of four and a half decades, written from the point of view of an activist educator. With the focus on Tanzania, they cover education in the German colonial era, the days of Ujamaa socialism and the present neo-liberal times. Themes include the social function of education, the impact of external dependency on education, practical versus academic education, democracy and violence in schools, the role of computers in education, the effect of privatization on higher education, misrepresentation of educational history, good and bad teaching styles, book reading, the teaching of statistics to doctors and student activism in education. Two essays provide a comparative view of the situation in Tanzania and the USA. Linking the state of the educational system with society as a whole, they explore the possibility of progressive transformation on both fronts. They are based on the author's experience as a long-term educator, his original research, relevant books, newspaper reports and discussions with colleagues and students.
