Setting a comfort level for a new class, introduce the instructor and share his/her background of their work. I would get a quick name of each student and what they expect this class could do for their career. Make your students feel desired and eager to learn, give them the first day course syllabus and what is expected from them. I don't want my students to feel that pressure, make their learning enjoyable, with real world examples the instructor may have experienced, and shop safety is an important one for my class. No horse play with tools and equipment will not be tolerated.
