For C. Roland Christensen, there is a magnificence in all teaching. Christensen's discussion methods of teaching involve everyone, especially the instructor who guides the class. You want to go beyond transferring knowledge to seeking to transform students in that knowledge. Make the students receptive to instruction by allowing them to feel welcome.
Every student teaches and every teacher learns.
If you genuinely believe that we have a lot to learn from our students, they will feel welcomed. Among those rules would be to stick to the topics at hand and to be courteous. There is a purpose for the class, and in a discussion, you have to create a community of learners. The smart teaching fellows I've observed have prepared ahead for how to handle being challenged. Walk to the blackboard and pause to think for a moment.
