Return to Collaborative Online Investigation information page.

In the online collaboration we want students, and ourselves for the sample investigation, to share GeoGebra applets that advance the exploration and also provide the reasoning behind the GeoGebra constructions. Reasons could be posted via text, but this can be tedious. We have found that students often provide very short insufficient explanations in text, but they are more ready to expand on their ideas using video and audio recording. We will use the Jing software to make video recordings of the computer screen while working with GeoGebra. At the same time we can create an audio record of our reasoning. The videos will be uploaded to the Screencast.com space. Code from Screencast.com can be embedded in a wiki page and with this the video and audio will play from the wiki.

The two blocks of instructions below show the steps required to record a Jing video, upload to Screencast.com, and link the video to a wiki page.


Record a Jing Video & Upload to Screencast.com
  1. By exploring in GeoGebra decide upon the steps you wish to show and the reasoning to be presented.
  2. Start with GeoGebra in its initial form or as you saved it from an example on the wiki.
  3. Start Jing if it is not already running on your computer. You will see a yellow sun jing_sun.pngat the top centre of your computer monitor.
  4. Click on the Jing sun and then on the capture option jing_capture.jpg
  5. With your mouse and left-click, drag the cross hairs from the upper-left to lower-right of the region you wish to record - the GeoGebra window. Click the video capture option video_capture.png
  6. Jing will count down for 3 seconds and then begin recording the highlighted area of the monitor screen and anything you say into your computer microphone. It might be best to do a test recording to ensure that your voice is being picked up.finish.png
  7. Once you have completed your work in GeoGebra and the oral explanation click the Finish button to stop the recording.
  8. On the new menu panel name your video and share_video.png
    click the share/upload icon.
    You will see a popup showing the progress of uploading uploading.png
    the video to your Screencast.com space.
