The chat tool enables participants to have text-based, real-time synchronous discussions. Chat enhances social presence in a topic, particularly for students who are external. If between student and teacher, chat enables active teaching and feedback.
Chats are especially useful when the group chatting is not able to meet face-to-face, such as:
regular meetings of students participating in online topics so they can share experiences with others in the same topic but in a different location
a student temporarily unable to attend in person chatting with their teacher to catch up with work
students on work experience discussing their experiences with each other and their teacher
a question and answer session with an invited speaker in a different location
sessions to help students prepare for tests or exams where the teacher, or other students, pose sample questions.
