Instructor image is everything. Being judged by your students from the first day of class sets the tone for the remainder of the the time together. Its important to present yourself in a respectful, organized, humbled manner so that students feel comfortable, trust in your knowledge and welcomed. Instructors shouldnt assume students know the classroom rules, the matierial or that their age respresents maturity. Its important that we prepare ourselves as instructors before entering each class lecture/lab so that we can show our students how prepared/organized we are and knowledgeable enough to be the right fit for their learning experience.
