内容概要

　　This book is organized as follows. Chapter 1 introduces the research background and purposes of this study. Chapter 2 recognizes the theoretical foundations for this study. Chapter 3 explores the e-learning context.Chapter 4 discusses peer interaction in the e-learning context， and suggests that effective peer interaction should be built on the considerations of knowledge relevance， social proximity and technical access between participants. Chapter 5 proposes a three-dimensional CA model for peer recommendation. Chapter 6 describes a CA-supported peer recommendation mechanism， which is based on mining learners activity contexts in e-learning spaces. Chapter 7 presents a prototype case study （PeerFinder）， which implements CA in a weblog system. Further discussion is provided in Chapter 8.
