Lack of plain English usage
In general across the E-learning process, the common problems would be usage of English. As the process of E-learning is completely online based, different listeners and presenters are accommodated on a single online platform, there would be lot of cultural and language problems while gathering together on a single lesson.
If the English used by presenter is tough and not able to understand by a set of listeners, the overall flow of the E-Learning process is affected a lot in most of the cases. If the listeners come up with some queries across the session, those queries may not be understand by other listeners and even presenters in some cases and thus the objective of E-Learning process is completely affected.
