Digital instruction is commonly divided into “asynchronous” and “synchronous” modes, with “synchronous” referring to real time teaching in a classroom or virtually over Zoom or other video conference tools. “Asynchronous,” on the other hand, refers to activities performed by students and instructors anytime—at home, in the library, even while commuting, doing homework, emailing, posting messages, and consuming videos and podcasts, reading, writing and so on. Since these words derived from Greek can be off-putting technical jargon, I’m proposing “online” instruction as a substitute for synchronous and “offline” for asynchronous.
