Creating effective presentations

I’m working on a presentation on creating presentations.   What other advice would you offer? Note: Open the speaker notes to view the image credits.

Poverty

  Whenever John (not his real name) entered my class, we had to open the windows. He smelled really bad, most of the time. He also wasn’t in class very often, and I never knew when he would be school, and when he wouldn’t be in school. There seemed to be no rhyme or reason […]

Host your own services

I think I need to understand his definition of simple better, because I do not see […]
