This document discusses principles for designing effective asynchronous online discussions in the Brightspace learning management system. It outlines three key principles: 1) Discussion as social engagement to build an online learning community, 2) Discussion as knowledge construction through social interaction and negotiating meaning, and 3) Discussion as enhancing cognitive processes by guiding learners to apply knowledge. Specific strategies are provided under each principle, such as using icebreaker discussions to build social engagement. The document also provides an example discussion design from a Calculus course to illustrate how discussions can be constrained through note starters and conditional release of posts.
