This book investigates the efficacy, economic viability, and systemic impact of open and distance learning (ODL) within the context of educational development in low- and middle-income nations. Hilary Perraton, a veteran researcher in international education, synthesizes decades of empirical data to evaluate how distance education functions as a tool for social and academic advancement. The text provides a rigorous framework for assessing whether ODL serves as a sustainable solution for expanding access to schooling, teacher training, and higher education in resource-constrained environments.

Experts recognize this work as a foundational text for policy makers and practitioners navigating the complexities of educational infrastructure in developing regions. Readers frequently note the academic density of the prose, which provides a balanced, evidence-based appraisal of both the potential and the limitations of distance learning systems.
