Synchronous adj : instructor’s delivery of online course content and participation by online students occurs at the same time.

With this type of online course, educators rely on technology such as video conferencing, chat rooms, webinars, and phone conferences.

Asynchronous adj : instructor’s delivery of online course content and participation by online students not occurring at the same time.

For those who opt for an asynchronous distance learning course, there are no scheduled online class meeting times and interaction between online instructors and students are normally delayed. Educators rely on discussion boards, e-mails, and prerecorded videos to communicate with their online students.
