Animated PowerPoint as a tool to teach anatomy.

Anatomy is a visual science. For centuries, anatomic information has been conveyed through drawings that have been presented to students through every available medium. The projection of animated images from a computer is a medium that offers great promise in effecting improved communication of anatomic information. Using Microsoft PowerPoint software, we have developed animated presentations for all of our lectures in Gross and Developmental Anatomy. As a starting point, we scan pen-and-ink drawings to create a digital image. The image may be edited and manipulated in an image processing program. Next, the image is imported into a PowerPoint slide where it is labeled and otherwise enhanced (arteries overlaid with red color, veins in blue, etc.) and the enhancements are animated, as we describe here step by step. For the lecture, the file is loaded on a server that is accessible through a network from a computer in the lecture hall. The output is directed to a video projector and the PowerPoint presentation is projected in the "Slide Show" mode. We use a wireless mouse that allows us to control the presentation from anywhere in the room. Before the lecture, students are provided with the same unlabeled drawings as handouts, and during the lecture the students are actively engaged in labeling the drawings and making related notes. After the lecture, the file is saved in HTML format and posted on our course web site where students can access the slides. Evaluation by the students at the end of the course demonstrated that this style of presentation was very favorably received.
