No lecturer goes into a series of lectures without some form of plan. So here are my thoughts on the subject. Its early day on the slides, but I hope they will help new lecturers plan out a leson.
So often you take over a lesson and there is no plan, or its outdated, or it just does not work. My advise start affresh and make a new plan, Your could even copy my format, its worked for me for several years on different semesters.
