  1. 1. Tips on using my ppt. 1. You can freely download, edit, modify and put your name etc. 2. Don’t be concerned about number of slides. Half the slides are blanks except for the title. 3. First show the blank slides (eg. Aetiology ) > Ask students what they already know about ethology of today's topic. > Then show next slide which enumerates aetiologies. 4. At the end rerun the show – show blank> ask questions > show next slide. 5. This will be an ACTIVE LEARNING SESSION x three revisions. 6. Good for self study also. 7. See notes for bibliography.
