Updating sequence of online courses for new learners while maintaining previous sequences of online courses for previous learners

Abstract:

A method can present a new sequence of online courses within a specialization for a group of new learners while maintaining a previous sequence of online courses within the specialization for a group of previous learners. The method can include maintaining a base class, associating a first learner with the base class, receiving a request to update a previous sequence of courses, generating a child class, associating a second learner with the child class, responding to a request for a sequence associated with the first learner, and responding to a request for a sequence associated with the second learner.
