·         improved legibility and clarity of lecture material
·         reduction of time required for lecture presentation

·         greater focus and attention from the students when relieved of the burden of trying to copy a blackboard presentation
·         opportunity to incorporate computer-based presentations for large lecture sections and distance education through closed-circuit video linkages

TIPS FOR USING THESE POWERPOINTS:

--After downloading the files to your hard drive, open the file and select the menu items: Slide Show / View Show.

--You can move through the presentation with mouse clicks. Notice that the navigation pop-up menu at the bottom left corner allows you to jump around in the presentation or stop the slide show.

--The green left-arrow is an action button that automatically takes you to the Table of Contents page, where you can move directly to select topics in the presentation using the hyperlinks list.

--As you go through the presentation, you will see several slides that bring up discussion points one-at-a-time with each mouse click. Each discussion point that shows up in this way is formatted as a bulleted list item. If you do not want to use this feature, it can be disabled by making the menu selection: Slide Show / Setup Show and then clicking the “Show Without Animation” box in the “Setup Slideshow” dialog box.

--To omit a given slide from your presentation (without deleting it), select the menu items: Slide Show / Hide Slide.

--To view the presentation as a web page, select the menu items: File / Web Page Preview. This is the most platform independent way to distribute the presentation.
