PowerPoint
PowerPoint is an extremely powerful instructional tool that can be used for much more than presenting bulleted text outlines in class (though it can do that, too!). PowerPoint permits instructors to easily load any object (e.g., photos and drawings, text, graphs and charts, audio and video clips) into slides for presentation.
