Here is how it works. The instructor sets the criteria and can communicate the particular warning to the student(s). In addition, the instructor has control over the message each time a warning is created, and also has the choice to use the default message or to modify it to more accurately communicate the seriousness of the situation. By keeping track of online students' at-risk academic behavior, faculty can plan successful interventions that will scale down attrition rates and improve retention.
