Synchronous and Asynchronous
The difference between synchronous and asynchronous communication is the time in which the answer for determined issue can be given. Haefner (2000) defines Synchronous communication as a simple communication that happens at the same time, and immediate answers are provided in give-and-take discussion sessions, a synonym of synchronous is simultaneous.
Some of the pedagogical interventions that synchronous communication may have are:
It allows immediate communication with interchange of much more information. It allows also the participant’s verbal development through discussions, where they have to find immediate answers by doing brain activities in which learners need to use their background, and relate it with the information they are discussing at the moment. Besides it allows better interaction increasing students’ fluency when exposing their ideas and social skills because, even if the communication is online, students are challenged to be attentive to the conversation with others.
On the other hand Asynchronous communication according to Haefner (2000) refers to the communication that can wait because does not require reply at the moment. Learners have a flexible schedule, however it can be difficult for them to have answers immediately in case they have doubts.
Some of the pedagogical interventions that asynchronous communication may have are:
Sometimes students need guidance for doing specific tasks and using this kind of communication answers can take hours, even days (Haefner, 2000). However, it allows more flexibility to work and reflect on the work and the comments or ideas that students are going o share. It also helps to give more specific feedbacks from the tutors because they have the time to consider many different aspects of the Information that is going to be given.
