摘要：The sustainability of Networked Collaborative Learning (NCL) is a key topic of discussion amongst the institutions where it has been or may potentially be introduced. Trentin’s book delineates a framework for NCL sustainability. After comparing NCL with other Technology Enhanced Learning (TEL) approaches and discussing the possible reasons for adopting it (Chapter 1), a multidimensional model for the sustainability of NCL is proposed. The model is characterized by four dimensions: pedagogical approaches (Chapter 2), e-teacher professional development (Chapter 3), instructional design models (Chapter 4) and evaluation/assessment approaches (Chapter 5). The four-dimensional model in developing NCL can be taken as a roadmap to understand the book. Each of these dimensions is examined on the basis of the author’s direct experience gained through applying NCL to his university teaching. The insightful and profound scrutiny on NCL in this book is of great significance for educators, especially teachers and will-be teachers who are puzzled at how to adapt themselves to meeting the needs of the future society and educating the 21st century students properly.
