Basic Android Setup

1. Instructor Notes
To the instructor:
This slide set has been prepared with both the highlights from the student text as
well as notes from the text. The students will not be able to see the notes unless
you provide them with the slide set. You can choose whether or not to provide that
option.
The notes are best seen by directing the main presentation to the LCD projector
and keeping the Notes view open on the instructor’s PC. You will find that pausing
the presentation to do some kind of activity at least once every 20 minutes is
critical to keeping PowerPoint from become tedious. Since different people have
different presentation styles, it would be impossible to provide a clear timing
structure. You should allow ample time for each slide, including stopping for
activities.
In case you have not done this before, the instructor notes are found by pointing at
Slide Show on the Menu Bar. Click on the Set Up Slide Show option and select the
Multiple Monitors  Show Presenter View.
Note: Presenter View also has a blackout button. Don’t be afraid to use it to
interrupt the tedium of staring at an LCD presentation when doing activities.
