Abstract: In one general aspect, a computer-implemented method can include scheduling a respective available open enrollment period for each of a plurality of cohort sessions for an online course, determining that a first cohort session included in the plurality of cohort sessions for the online course is open for enrollment, enrolling, based on determining the first cohort session is open for enrollment, a learner in the first cohort session, automatically tracking a progress for the enrolled learner, determining, based on automatically tracking the progress for the learner, that the learner is falling behind a predetermined schedule of course completion for the online course, and, based on determining that the learner is falling behind the predetermined schedule, automatically determining that a second cohort session included in the plurality of cohort sessions for the online course is open for enrollment, and enrolling the learner in the second cohort session.

Abstract: A method includes presenting an online education course on a first communication device. The online education course presentation includes a hierarchical schema of items grouped in one or more hierarchy levels and presented as web pages or item views on the first communication device. The method further includes integrating a navigation system with a current item view of the online education course presentation, the navigation system including at least one UI element that provides visual information about the current item view and its location in the hierarchical schema of the online education course, and at least one UI element that leads to a different item view from the current item view of the online education course presentation.
