Engage students by using interactive discussions, real-life examples, humor, multimedia, and active learning techniques to make lectures dynamic and relatable.
Prepare thoroughly about the topic - don't insult your students by being offhand and sounding like you couldn't be bothered.
Sense of humour - the most effective way of making a point. You don't have to cheapen the whole experience by making it stand up comedy but should lighten the class by making appropriate funny stories, anecdotes. Humour is easily the most effective way to make your point.
Consider them as equals. Don't talk down to them. Don't be patronising.
Admit when you don't know the answers(s). Ask the student to find out and don't stop there. Give them an opportunity to share the knowledge at the next session.
Cherish the "troublesome" students. They are often the brightest.
The students best enjoy professor lecture is when he/she is fully comprehended of the lecture and has wide knowledge about the contents of the lecture. I do like the professor be serious with the students and not joking or talking out the content of the lecture. There should be borders between the professor and the students, then there will be respect and honor and appreciation.
I generally agree with the points of Dr Sundus F Hantoosh - having been in such a lecture myself. The professor (new at my university, had only been there for a few weeks at that stage) - I thought it was a successful lecture at that time because I had also been there for a few weeks at university myself - and I think to myself why was it successful. The most important point was that he made it not too hard/technical so that both myself and other people in the lecture (who may have been in the field for many years) could all understand and appreciate what he was saying.
He also had very good slides/graphics. It is so important to have that. How important and helpful this is is discussed more here:
