In this unit you will consider how constructive feedback can be used to enhance learning in an online course. In a discussion based online course model, peer and instructor feedback are equally important. As you participate in online discussions, commenting to your classmates on their posts provides you with an opportunity to enhance your own learning by thinking about the content in terms of what others say about it, or don’t say about it. Responding to your classmates and commenting on their posts provides them with constructive feedback on their own learning and understanding of the material. Teaching and learning occur at the same time as you develop comments that others can use to enhance their own learning. In this tutorial, you will explore the affects of good feedback and its importance in e-Learning.
