I generally prepare presentations to use as a guide. I prefer student interaction and engagement about the content. I use real live experience and case studies to cover the required content. I have had many years business experience in multinationals and SMME's in different parts of the world. I have lectured part time at universities and colleges. Due to my methodology, my students always loved my classes.
I do not simply repeat the content of the textbook. That is for you to read!
