This version of the presentation includes notes for the instructor. The presentation has been designed so that each slide is self-explanatory and its function clear. Review the presentation first, as you would your own lecture material. Then, when it comes time to give the presentation, simply read out the slides to your audience, adding your own observations, anecdotes and humour as you go. For extra guidance, instructional notes have been provided for each slide. The presentation has been designed for general use, with no particular course in mind. You may feel that some slides are not relevant to your particular case. Simply omit or modify those slides to suit your requirements, or insert slides of your own in the slide-show.
