Education is changing rapidly. Many universities start to provide their courses on-line, free for everyone to take. To keep up with these developments, I made a short do-it-yourself (DIY) video lecture — appropriately discussing online education — which combines 4 techniques: 1) an ordinary lecture with slides, as always; 2) my talking head from the webcam; 3) written notes on the slides, “Khan Academy-style”; 4) a screencast, capturing live actions on the screen.
In case you like to do this too: The video was made using recordMyDesktop, CamDesk, Xournal, and edited with OpenShot, all running on Ubuntu. I used a webcam to record myself, and a pen tablet (Wacom Bamboo) to annotate the slides. As can be seen, the result is not great: The number of frames per second is low (default is 15 frames per second in recordMyDesktop), the audio quality is low (I need a better microphone), and audio and video are slightly off (not sure why this happened). On Windows a combination of CamStudio, Powerpoint, and Movie Maker might do better.
Many thanks to the following people that advised me or otherwise supported me in making the test online lecture: Wanno Drijfhout & Marije de Heus (Course Managing Big Data), Theo Huibers & Eelco Eerenberg (Thaesis), Tonnie Tibben (Twente iTunes U), Alfred de Vries (SmartXP lab), Peter de Boer & Roy Juninck (FB lecture halls and digital whiteboards). Additional advise and comments are very much appreciated.
One thought on “DIY online lecture”
Here are the results done by our students for the course Managing Big Data: 1) Wanno Drijfhout, presenting Traitor; and 2) Marije de Heus, presenting Readability of the web
