Activities are considered asynchronous when they do not require real-time interaction in order to allow students to access learning materials and complete tasks at their own pace and convenience. What characterises asynchronous activities is that they are often self-directed and allow for flexibility in scheduling. Some examples of asynchronous learning activities in blended learning include pre-Recorded lectures or online assignments and assessments. The prior requirement is that the teaching staff should prepare and provide recorded video lectures that students can access and view at their own preferred time and pace; self-paced learning modules are similarly flexible, in the sense that teachers create online learning modules, readings, quizzes, and other materials which students can complete at their own pace and time. The latter is a way of examination, where students can submit assignments, quizzes, or tests electronically without the need for simultaneous participation.
