    22. Instructor note: Slides up to this point can be delivered in a room other than the computer lab. This may be a good idea in order to develop rapport, establish a flow for the day, and ease people into computer use. Some participants will have little prior experience with computers. Starting in a more familiar setting (instead of in front of a computer) may help to ease them into feeling comfortable in front of the screen.
