Class begins with a greeting. I introduce myself and provide a brief biography. I then ask each of the student to introduce themselves. I like to know where they're from and what program they are taking. After the introductions are over everyone is a bit more at ease. I then begin to explain the expectations in the class. this falls into 2 catagories. The first being expected professional behavior. The second being what is expected of their technical skill to pass the class. Setting the expectations on day one establishes the appropriate tone for the remainder of the class.
