When teaching adult students i've learned that people learn completely different because some people are book driven  or people are more hands on, its all about understanding a teaching method for success in your students 

Always practice demonstrations prior to your lecture so when you deliver your students will have a better understanding of what you are teaching

Introducing yourself to your student's so they will be less nervous, as well allowing them to introduce them selves so they can be more comfortable. 

Clear communication, understanding your student's needs to better help them understand there assignments to be successful in the medical felid. 

I have learned to do not try to show my students that i am smarter than them, to help them understand that we are all learning and engaging on how to become professionals in the medical felid.
