First thing I ve learned as an instructor is that one has to know and learn thyself. Passion in teaching will only surface if this is really a true calling. An instrcutor may have all the knowledge and credentials in the field but being able to disseminate the information to the students is another story. Second thing, know thy students. Make it a game by memorizing students first names during the first week. Call their first name. This is the only way that students will know that they are valued in the classroom because they are known not only by the instructor but also by the students.
