Jack and I decided to keep his paper in his Acrobat format since much of the concern of the paper is formatting PowerPoint slides. The paper begins on the next page.
Building a PowerPoint™ Presentation
The purpose of this document is to illustrate how one can build a Power Point slide to be used to illustrate one idea, here the concept of net ionic equations. The directions are based on the version of Power Point (Version 8.0) in Microsoft Office 98 for the Macintosh. To do this one must also have the Saunders Interactive General Chemistry CD-ROM mounted in the CD drive. Adobe Acrobat versions of the PowerPoint slides used in some sections of General Chemistry 111 at SUNY-Oneonta are found at http://www.oneonta.edu/-kotzjc/genchem.html. Users of Saunders textbooks can download the PowerPoint slides for all of general chemistry from the website for the Saunders general chemistry books: http://www.saunderscollege.com.
After setting the animation, the slide is shown as follows:
1. The slide appears on screen with the title and the movie frame.
2. The movie plays when clicked with the mouse. (We always do the same reaction "live" in a dish on an overhead projector at the same time and ask the students to make observations.) We also try to get the students to write the overall, balanced equation.
3. Next a mouse click brings the first equation on the screen. The students are asked to write out the species as they would actually occur in solution, that is, write the equation with HCl and MgC1 2 broken into their ions. Another mouse click brings the second equation onto the screen.
4. We then look for the spectator ions, and mouse clicks cause the yellow rectangles to appear to highlight those ions.
5. Finally, the last sentence is brought onto the screen with a mouse click.
6. Other reactions are demonstrated in the lecture and students are asked to write net ionic equations on a worksheet provided in the lecture.
RECORDING SOUND: As a final point, note that one can add voice-overs to slides. Go to the "Insert" menu, then to "Movies and sounds," and then to "Record sound." After the sound is recorded, a "speaker" icon appears on screen. Clicking on this plays the recorded sound. This is useful when you want to students to look through the slides by themselves but you want to fill in details and add context.
