What does it mean that all classes will use “distance learning?”

Distance learning includes two primary techniques, 1) Video conferencing or synchronous learning, often using Blackboard Collaborate or a similar platform, where all participants gather at the same time but from their chosen location and 2) Asynchronous learning, which involves participants sharing learning materials on their own schedule and from places of their choosing, though often with expectations and specific deadlines for sharing materials.
The SUNY Poly faculty are currently redesigning courses for the remainder of the semester to be delivered via distance education, using an appropriate combination of synchronous and asynchronous techniques.
