Asynchronous Learning

Asynchronous learning is a general term used to describe forms of education, instruction, and learning that do not occur in the same place or at the same time. The term is most commonly applied to various forms of digital and online learning in which students learn from instruction (prerecorded video lessons, game-based learning tasks that students complete on their own), that is not being delivered in person or in real time. It mays also encompass a wide variety of instructional interactions, including email exchanges between teachers, online discussion boards, and course-management systems that organise instructional materials and correspondence, among many other possible variations.
It should be noted that the term asynchronous learning is typically applied to teacher-student or peer-to-peer learning interactions that are happening in different locations or at different times, rather than to online learning experiences that do not involve an instructor, colleague, or peer.
