There are many facets to online teaching; in fact, online instructors have to be more skilled than face-to-face ones so that they can effectively handle a set of students who are connected to them only through a computer interface. The teaching methods they adopt are also more complex and demanding than classroom techniques. Online teaching is an amalgamation of both synchronous methods like online lectures, and asynchronous ones like emails, discussion forums and bulletin boards. Though video and audio conferencing are gaining popularity, Bizbrim advocates against their use, since these techniques require a higher bandwidth and seldom work properly on all systems.
