For Lesson Content Groups, there is a group chat function which allows the Instructor to have scheduled chats once or twice a week to interact with the students on the lesson just like a virtual classroom. The exact timing of the group chat is stated on the every lesson page itself.
For questions on quizzes, the student should message the Instructor since the group chat is to describe questions on the lesson itself.
Below is a page showing the Group Chat function which is the last tab on the Lesson Content Group page.
When the scheduled time is reached, the student can click on it to join in the chat.
Below screen is an example of the chat room from Jon’s perspective. The Instructor is joined by students Jon and Jessica. There are two window : the top window displays User List i.e. those who are present in the room and the second window shows the chat itself.
