asynchronous and synchronous learning

In the subject e-learning, we have learned about synchronous and also asynchronous learning. What is synchronous and also asynchronous learning means? Synchronous learning refers to a group of people learning the same thing at the same time in the same place. This is the type of pedagogy practiced in most schools and undergraduate programs, but not in graduate programs. Telephone conversation and also instant messaging is the example of synchronous learning. While, asynchronous learning is a student-centered teaching method that uses online learning resources to facilitate information sharing outside the constraints of time and place among a network of people. It also emphasizes the importance of peer-to-peer interactions. E-mails, discussion boards and also text messaging is the example of asynchronous learning.
