Online learning management systems can be used by K-12 teachers to supplement standard classroom learning. These systems allow teachers to create online classes, assignments, quizzes and forums to provide students access to course materials anytime from home. They provide benefits like keeping parents informed and engaged, aiding students who miss class or are struggling, and keeping teachers up-to-date with technology used by modern students. While initial setup may require work, these systems can save teachers time and effort in the long run by storing all course resources in a central online location.
