Todd ponders the challenges of building meaningful online communities that last beyond a single class semester or year. He acknowledges the constraints of learning management systems but believes communities could form more frequently if teachers and students embraced the idea of ongoing learning networks rather than seeing their class as an isolated event. Todd suggests role modeling active engagement, relating content to the present, recognizing weekly student contributions, allowing outside content, and following a 30/30/30 rule for discussion to help form communities within the constraints of the current class semester.
