The instructor needs to develop stratagies to manage the behavior of the "center-stage" student. This is so that each student in the class has equal opportunity for participation, and also so that the center-stage student doesn't take over the leadership role in the classroom (by taking that role away from the instructor.)
The instructor can manage behaviors by delploying stratgies such as giving a set number of opportunities per student to participate in the class.
Delegating the center-stage student to the role of monitor/observer, whereby they take notes on the lecture and then summarize for the class in their own words from the notes they've taken.
