I believe that, we must provide an environment that is interactive and collaborative and that promotes problem-solving and critical thinking skill, encourage students to ask questions and freely give their views on the material which we are covering. We should not make the things hard for to be a good teacher. Highlights to remember life-long should be emphasized and facilitate learning, not memorizing. Using current teaching tools available, be supportive and contribute their advancement and encourage for further learning and practical skills. A team-work with clinical tutors, students and other faculty as equal partners in line of teaching and improving the experiences.
