"August 1, 2011, 5:51 pm By Rachel Wiseman College students with very poor vision have had to struggle to see a blackboard and take notes-basic tasks that can hold some back. Now a team of four students from Arizona State University has designed a system, called Note-Taker, that couples a tablet PC and a video camera, and could be a major advance over the small eyeglass-mounted telescopes that many students have had to rely on. It recently won second place in Microsoft's Imagine Cup technology competition. (...) The result was Note-Taker, which connects a tablet PC (a laptop with a screen you can write on) to a high-resolution video camera. Screen commands get the camera to pan and zoom. The video footage, along with audio, can be played in real time on the tablet and are also saved for later reference. Alongside the video is a space for typed or handwritten notes, which students can jot down using a stylus. That should be helpful in math and science courses, says Mr. Hayden, where students need to copy down graphs, charts, and symbols not readily available on a keyboard. (...) But no tool can replace institutional support, says Chris S. Danielsen, director of public relations for the [NFB]. "The university is always going to have to make sure that whatever technology it uses is accessible to blind and low-vision students," he says. (Arizona State U. has gotten in hot water in the past in just this area.) (...) This entry was posted in Gadgets."

Although the First Amendment may appear unconditional on its face, the right to speak and write freely has never been absolute. Intellectual property rights often prevail over an author's "creative license." The main benefit of copyright, for example, is the right to exclude others from making copies of a work (or any part of it) without permission. By protecting an author's expression, copyright guarantees that authors and other creators, derive financial benefits from their work. If you intend to use someone's copyrighted work, unless the use is considered a "fair use" (which is technically a defense to copyright infringement), you must obtain that person's written permission. Under federal law, only the copyright owner or someone acting with the owner's authority, such as a publisher, can grant that permission. Without written permission, you expose yourself to legal risks. While not every unauthorized use of a copyrighted work is an infringement, whenever you include another person's words, illustrations, photographs, charts or graphs in a work you publish, you must be sensitive to the risk of infringing someone's copyright. What follows are some common copyright permission myths.

When you want a quick graph of a function, you can just type in http://graphsketch.com/[function], like http://graphsketch.com/sin(x). You can even separate multiple equations with commas, like http://graphsketch.com/sin(x),x^2.

Fascinating cross-curricular project from Jennifer Tan's diigo bookmarks (she joined the educators group tonight.) Mathematics students determine whether Poe's story is mathematically sound using graphing calculators and computers.

Excellent example of cross curricular projects
