Teaching with Discussions. One of the most challenging teaching methods, leading discussions can also be one of the most rewarding. Using discussions as a primary teaching method allows you to stimulate critical thinking. As you establish a rapport with your students, you can demonstrate that you appreciate their contributions at the same time that you challenge them to think more deeply and to articulate their ideas more clearly. Frequent questions, whether asked by you or by the students, provide a means of measuring learning and exploring in-depth the key concepts of the course. Be planful in how you start maintain, and finish the class discussion.
