Chapter 1 Introduction -- Chapter 2 The importance of motivation in online learning -- Chapter 3 The case studies -- Chapter 4 What do the case studies tell us about motivation? -- Chapter 5 Motivation guidelines for teachers, designers and learners -- Chapter 6 Concluding remarks.This work explores and explicates learner motivation in online learning environments. More specifically, it uses a case-study approach to examine undergraduate students’ motivation within two formal and separate online learning contexts. In doing so, it recognizes the mutually constitutive relationship of the learner and the learning environment in relation to motivation. This is distinctive from other approaches that tend to focus on designing and creating motivating environments or, alternatively, concentrate on motivation as a stable learner characteristic. In particular, this book identifies a range of factors that can support or undermine learner motivation and discusses each in detail. By unraveling the complexity of learner motivation in such environments, it provides useful guidelines for teachers, instructional designers and academic advisors tasked with building and teaching within online educational contexts.
