What is the difference between synchronous and asynchronous interaction, and what are some of the advantages and disadvantages of each?
Doris Cheung 11/3/97 Synchronous is “a term that refers to communication in which interaction between the sender and the receiver is not delayed” (Willis, p. 302). In other words, the interaction occurs in real time. Types of synchronous interaction include two-way audio, two-way video, computer document conferencing, and “chat” rooms. Asynchronous refers to “communication in which interaction between the sender and the receiver does not take place simultaneously” (Willis, p. 291). This delay in communication may be a matter of hours, days, or even weeks. Examples of asynchronous interaction include voice mail, correspondence by mail, fax, computer e-mail, and electronic bulletin boards. Some advantages of synchronous interaction are: • It allows real-time contact/discussion between the students and the instructor (Guide #11). • It can be used to promote social interaction among the students (Berge, 1995). • It can provide a feeling of “connectedness” for the learner (Willis, 1994). •
