Several students tiold me I'm "hard but eay". I push the envelope, I state my expectations from the first class.
When students "don't get concepts" from quiz or homework, I invite discussion/feedback from students. What are they doing or not doing? Why are they not understanding key concepts I lecture (PWR PT). Feedback provides students opportunity to see what I can do to improve their focus on class material presented.
HARD: I make them adhere to school policies, wearing the uniform (scrubs), being on time, taking responsibility.
EASY Even though sometime difficult concepts, I break it down in steps. It make it fun (laughter with learning. I trweat them with respect.
I allow myself and students to ask with my answers/responses to them via email after class and I always respond to their questions, try to give tips of improving their comprehension of subject matter.
