This book contains a study of the process of educational change in developing countries. It is being disseminated in the hope that it may stimulate interest in the process of change, so that a more experimental and evaluative approach may emerge in the search for a better system of education. By looking at several different sources of information about educational innovations and by inserting them in a conceptual framework, the authors try to explain how educational change occurs in different settings, why it occurs in the ways it does, and some of the implications for managing change in developing countries. The emphasis in the book is on presenting and analyzing data collected and on some preliminary ways of drawing practical lessons from them. The data presented come from five sources: (1) case study literature published within the past five years; (2) a stratified sample of detailed project evaluation reports; (3) a questionnaire administered to 81 technical advisors and national directors of teacher education projects in the principal regions of the world; (4) 27 interviews conducted with a sample of the survey population and with a number of experienced administrators, experts, and national officials; and (5) recent theoretical literature of educational change. Findings show that, in spite of large scale investments and high expectations, few innovations make a major dent at the national level in the educational or training problem which they were designed to solve.
