Hi Ann, You are correct about the environment being everything. It is often helpful if instructors will step outside of themselves for a time and try and see the classroom or lab through the eyes of their students. As humans we get used to our surroundings very easily and with time we accept the environment in which we work, be it good, bad or somewhere in between. By constantly looking at the classroom, making sure supplies are sufficient, and that the appropriate technology is available the instructor is then free to focus on the learning needs of students.
