Hi Anna: No ones personality is exactly alike. I think it's a mistake to emulate someone else in an artificial way. Many times, we revert back to how it was when we were in school. I believe being honest and sincere, natural in our delivery, calm and relaxed, and conveying a care and comforting demeanor will most always be received well. Also, teachers should demonstrate courtesy and esteem for their students as a basic foundation. We may need some on course correction for students, but that, done in private, and expressing a genuine concern for the success of the student will achieve better results and may contribute improved trust and mutual respect.
