Instructions which encourage live participation and interaction through online classes are called:
Synchronous instructions
In online and e-learning environments, instruction is broadly of two types depending on whether teacher and learner interact at the same time or at different times.
Synchronous instructions take place in real time, where teacher and students are online simultaneously and communicate live. Live online classes, video conferencing, webinars and chat sessions that encourage immediate participation and two-way interaction are synchronous, because everyone is present at the same moment and responses happen instantly.
Asynchronous instructions are the opposite: recorded lectures, emails, discussion forums and self-paced modules where interaction is delayed and learners access material at their own convenience, so there is no live participation. Traditional instructions refer to conventional face-to-face classroom teaching, not online classes. Theoretical instructions is not a recognised category of online instruction at all. Since the question specifies live participation and interaction through online classes, the correct type is synchronous.
Correct answer: Synchronous instructions
