The key is trust. Trust comes from the instructor's credentials and professional experience. Conveying this to the students is important for them to entrust their education to the instructor, but trust comes to understanding. The instructor should also learn about the student's goals, experiences and more to build a relational bridge to support the weight of academic rigor, and possible admonishment. It's the old adage, "People will not care how much you know until they know how much you care".
