I would like to add that besides the regular ways of teaching,like a lecture,ppt or just oral presentation there should be ways to grab our students attention,I need to bring in all the diff ways I can in order to capture my students attention,as it becomes boring and students tend to just seem to have ADD!i teach the same subject sometimes 6 hrs/day,if anyone has some new ideas to share please do let me know,for example, if it is an Anatomy and physiology class, and have to cover 3 chapters in 5 hrs!what are the different ways to make this long class interesting as well as giving them all the course objectives to be covered in that time frame.
