From site: Mathtrain.TV is a free educational “kids teaching kids” project from Mr. Marcos & his students at Lincoln Middle School in Santa Monica, CA. Mathtrain.TV was created by middle school mathematics teacher, Eric Marcos. It is part of the Mathtrain.com Project and was created to host our student-created math video lessons all in one place. It is Web 2.0 friendly with its ability for users to generate “ratings” and “comments”. Our middle school students use a tablet pc and screen-capturing software, Camtasia Studio, to create the math tutorials. The site is powered by PHPmotion, a free video-sharing software.
Students at Lincoln Middle School create math video lessons (screencasts or mathcasts) which are used for classroom instruction and posted onto sites such as Mathtrain.TV, Mathtrain.com, iTunes, YouTube, TeacherTube and Google Video. Our students work hard at creating the content and construct the best explanations they can in our unscripted format. The videos are offered free, “as is” (under a Creative Commons agreement) and we take no responsibility for any inaccuracies or errors which may exist in the content or site. All videos are reviewed (and sometimes further edited) by a credentialed math teacher. In an effort to make our videos available to many different learners, we are in the process of closed captioning (CC) our videos. At the moment, there may be two versions of the same video lesson on this site; one with and one without captioning. On other videos, we may “burn” the captions right onto the video itself. As technology progresses, we hope to offer our viewers the ability to toogle on and off between closed captioning and even alternative language subtitles. On Google Video, viewers have the ability to turn captioning on or off via the “CC” button. For more information about how to caption your own videos, go here: www.dcmp.org/ciy.
