Blended or Hybrid Learning combines face-to-face and online environments. The online component can be a learning management system such as Moodle, Canvas, Blackboard, virtual worlds such as Second Life or other SIM-like Virtual Worlds, a social network such as Facebook groups, Twitter, Discord, or any other Internet-based environment. The division of the time allotted to the face-to-face (in-person) and online environments will vary according to the needs of the organization.
Blended or Hybrid Online Learning takes place completely online with no face-to-face (in-person) activities. According to Michael Power, blended online learning is “a combination of both blended learning and online learning” (Power, 2008). Blended Online Learning or BOL was used in most countries around the world during the COVID Pandemic lockdown. No one called it BOL. They called it online or remote learning.
I think credit should go to Michael Power for coming up with the idea that you can teach online using asynchronous and synchronous environments. During the pandemic lockdown, I used Moodle as my asynchronous and ZOOM as my synchronous environment.
