When students encounter a difficult topic or section, their first instinct would be to ask help from the instructor. Because of this, communication methods are important for conducting online education. Typically, teachers would give students their e-mail address for any questions or clarifications. But with the many innovations of today’s online learning sites and web pages, there are other ways to communicate. Then some online course platforms have their own chat apps. Students and teachers can freely talk to each other in real-time for better communication.
