On-Demand Lectures Create an Effective Distributed Education Experience
Preparing a Tegrity Lecture With a Tablet PC
To demonstrate how easy it is to create a Tegrity recording with a tablet PC, the following is how a typical lecture is prepared, recorded and posted onto the course management Web page. Initially, I determine the material to be covered in the lecture. Each lecture is designed not to exceed about 45 minutes, which seems to be about the longest effective attention span for a streamed lecture. Then, using the tablet's software, I handwrite basic information to be put on each PowerPoint shell background on the pressure-sensitive tablet screen. Again, using software on the tablet, the information is placed in PowerPoint where the basic lecture is named and saved.
I then set up my microphone and Web cam on a small tripod. I start the Tegrity software right from PowerPoint and begin recording the lecture. Using the navigation panel, I advance the PowerPoint shells one by one as I lecture, annotating them as the lecture is being recorded. The annotations are recorded in real time as I write on the tablet PC screen - dynamically appearing to the viewer just as they would on a chalkboard. When viewing, students see and hear me along with the annotations as I make them, just as they would in a live class. With another click at the end, the completed session is saved and uploaded to the Tegrity server. The recording also can be edited using the Tegrity editor if desired.
Finally, I open the course management software and insert a link to the Tegrity recording in the correct unit. The entire process, including the recording of the lecture, takes about an hour and a half for each 45 minute lecture. Thus, first-time lecture preparation to actual lecture time is about a 1-1 ratio. However, once they are recorded, the lectures can be reused in subsequent classes or stored as reference materials.The best part, of course, is that I now have 100% of my lectures ready for the next time I teach this class.
