Video feedback in the classroom: development of an easy-to-use learning environment
John De Poorter, Lut De Jaegher, Mieke De Cock, Tom Neuttiens · Physics Education · 2007
Video feedback offers great potential for use in teaching but the relative complexity of the normal set-up of a video camera, a special tripod and a monitor has limited its use in teaching. The authors have developed a computer-webcam set-up which simplifies this. Anyone with an ordinary computer and webcam can learn to control the video feedback parameters in less than one hour. Besides the normal video feedback images, a simplified method to generate video feedback fractals is presented. Fractals such as the Cantor set and Sierpinsky triangle, along with new fractals, can be obtained, giving an insight into the properties of fractals.
