Document cameras are an easy to use, versatile and portable video making solution that supports learning. A recent study by Fiorella and Mayer (2016) demonstrated that videos where the instructor writes and draws in real time are more effective than static images. They also found that video learning is more effective when the instructor’s hand was visible.
I use an Ipevo Ziggi HD Plus (https://www.ipevo.com/prods/Ziggi-HD_Plus_USB_Document_Camera) camera.
The document camera plugs into the computer via a USB and the output from the camera is displayed on the computer screen. Screen capture software is then used to record a video. There is also a built in microphone to record the video audio, or you can use the built in microphone on your computer. The camera is awesome but the Ipevo Presenter software is not the best. So I use either Screencast-omatic or Camtasia for capturing the video.
Here is just a few of the uses I have found for my Ipevo Ziggi:
- Draft feedback- make a video as you annotate student’s drafts
- Solving maths problems, balancing equations.
- Map triangulation in geography
- Demonstrating how to draw a graph
- Demonstrating how to read a seismograph
- Science démonstrations- microscopy, optics, microbiolgy
- Stop motion videos
- Science and maths content videos.

When I am making content videos, I like to use A3 paper and write on it with Sharpies. I mark the boundary of the camera field of vision with a pencil. Try to avoid writing too many words. Pictures are very effective, especially if you draw them yourself.
Note: ELMO also have some great Document Cameras…. CR Kennedy are the Australian distributors and work closely with a lot of schools – https://crkphotoimaging.com.au/categories/_brands/elmo
