This chapter discusses methods for supporting the instructor in the development of strong learner-learner interactions. In this chapter, we present a brief overview of the importance of social learning theories and existing research that support learner-learner interaction as an important aspect of learning. Next, we discuss the multiple factors, and their complex interaction on the instructor’s ability to support learner-learner interaction. Additionally, we report and discuss findings from a qualitative study examining the use of an ecological assessment tool to evaluate an online course’s ability to support learner-learner interaction. The chapter concludes with suggestions for improved approaches to faculty development to support learner-learner interaction.
