Hi Louis,
The hybrid, synchronous class where some are present in the same room and others are 'skyped' into the class was a technique used in some of my graduate courses. It is an effective way to include those who are out of proximity, when needed.
Additionally, the convenience of asynchronous intereaction seems to be an important part of the growing popularity of online classes. Do you think the 'anytime' feature may play a significant part to increase the migration of students from the traditional to the online classrooms? Thank you for your contributions.
