The document compares face-to-face and online learning. Face-to-face learning allows for immediate feedback and real-time human interaction, while online learning provides persistent access to materials and more flexibility. However, face-to-face can be rigidly scheduled and discussions may be forgotten, while online lacks immediacy and discussions may become chaotic. Blended learning combines the benefits of both approaches by retaining immediacy and dialogue from face-to-face, while allowing for the persistence, flexibility and rich media of online learning.
