Is Online Learning Activities a Bad Method for Students?

Where are students more actively involved and able to understand the lessons from the teacher? Is it at school in person or online? Since the pandemic occurred all over the world, especially in Indonesia starting in March 2020, lockdowns have been implemented in various countries. Therefore, all activities from studying to working are done at home online. Then the question in this discussion is online learning efficient for students? I think a lot of people wonder about this. Learning online during a pandemic is indeed the solution at that time.
