In many ways, videoconferencing presentations are similar to presentations done in person. However, the technology provides unique opportunities for engaging participants and presents a few difficulties that should be considered when planning a videoconference presentation.
Wear solid colors
Cameras can have trouble transmitting patterns such as checks and stripes. So solid colored clothing is a good idea otherwise students may be distracted by unexpected video effects.
Create an engaging background
Backgrounds should be engaging but not distracting. Avoid using anything with a large amount of text or anything with moving parts that can distract and avoid blank, neutral-colored walls that can bore students. Large maps, book shelves, plants and lab equipment work well as long as they don't distract.
Consider your appearance on camera
Use animated facial expressions and hand gestures that will engage students in conversation. Overly enthusiastic is better than blank expressions; however, be aware that rapid hand movements may not transmit well on camera. Set the angle of the camera so that it is close enough for students to make eye contact, but not so close that you are a large talking head on a screen. Keep an eye on the monitor so you can make sure the students can see you, any gestures you may make and demonstrations clearly.
Speak slowly and clearly
Try speaking slightly slower than you would normally speak, particularly if there is a difference in language between you and the students. Enunciate your words and project your voice toward the camera. Consider creating some kind of visual aid or glossary that can be passed out to students for technical terms. Periodically check to make sure the audio equipment is working properly.
Use additional equipment effectively
Don't be afraid to incorporate additional technology and equipment into the presentation such as document cameras, lab equipment and computer programs. These can greatly enhance the information being presented, particularly if it is showcasing items that students may not be able to see otherwise or using equipment that isn't widely available. However, remember it is the human interaction that makes the videoconferencing experience unique, so punctuate all demonstrations and equipment use with face-to-face activities. Make sure all necessary equipment is nearby and fully set-up before the presentation.
Tailor presentations for the particular size of the group
Make sure the presentation is tailored to the size of the class (or audience). Demonstrations and short lectures work well for most group sizes; debates and group activities work best with small to medium-sized classes. If more than one class is involved, consider ways to engage classrooms with one another. Also keep the size of the classroom and presentation space in mind. If you are speaking to a large group in a lecture hall, make sure visuals are large enough for everyone to see and demonstrations don't require too many steps or detailed actions.
