The third characteristic is negotiation. This characteristic is a vital part of any type of learner-centered environment. If students are expected to take responsibility for their own education in these classrooms, then they must also be given some power to negotiate the terms that govern the atmosphere. The final characteristic listed by Burke is conversation. Conversation goes beyond simple communication in that there is active engagement between student and student or teacher and student.
Conversation makes construction, occupation, and negotiation possible.
I think that these characteristics are not only important characteristics of good teaching, but they are also important characteristics of the learner-centered environment.
