- W932340488 abstract "FROM HER FIRST ENCOUNTER with stereoscopic 3D technology designed for classroom instruction, Megan Timme sensed it could be transformative. was so engaged,' says Timme, principal at Hamilton Park Pacesetter Magnet School in Dallas, an elementary magnet school focused on fine arts and leadership. When I thought about all the possibilities of what could be done with it, l knew it would be fantastic.' Last spring, when she began pilot-testing 3D content in her third-, fourth- and fifth-grade classrooms, Timme wasn't disappointed. Students donning special 3D glasses were immediately absorbed in the immersive experience and caught up in the images that seemed to soar from the projector. They learned how to calculate the volume of unusual shapes through objects that could be moved around and viewed from all angles. They hopped aboard an asteroid (virtually speaking, anyway) for a tour of the solar system. They witnessed the life cycle of a plant, from seed through reproduction. They dissected a frog and went inside the human body to see how antibiotics work. Timme observed benefits for all types of students. Those who tended to be disruptive of inattentive during traditional instruction were so enamored they uttered nary a peep. Those with limited English proficiency suddenly had a visual that helped them grasp concepts where mere words had failed. Gifted kids were making so many new connections and asking such provocative questions that the lessons often mined territory far beyond what Timme and her teachers had anticipated. Now she has begun to consider what else the technology could have in store for her students. Imagine what could be done for lower grades in math instruction, she says. be able to show the kids in 3D what's actually happening when you're subtracting, I think would be a very powerful piece. [ILLUSTRATION OMITTED] Many of Timme's colleagues are likewise starting to imagine the possibilities. Now that 3D-ready projectors have hit the education market--it's estimated that 1 million will be sold this year--a technology familiar to movie theaters and becoming more so in living rooms is finding a new home in the classroom. What's not as familiar is how the 3D effect is produced. DLP chip technology that enables 2D projectors to play 3D content was developed by Texas Instruments (TI). It uses millions of microscopic digital mirrors that are manipulated at rapid speeds to produce two simultaneous images on a screen, one for the left eye and one for the right. Presenting each eye with a slightly different image is what creates the illusion of depth. 3D effect is generated by viewing the screen through special active-shutter glasses that open and close filters in front of each eye in sync with the images. It is the same technology used to create a third dimension in movie theaters. To be sure, this is nothing like your parents' 3D. [ILLUSTRATION OMITTED] The image quality is now much crisper, and the separation between what the left eye sees and what the right eye sees is much better, says John Reder, education market development manager for TI's DLP division. And the content providers have gotten smarter in the effects they produce. Reder credits Avatar, the blockbuster 2009 film directed by James Cameron, with demonstrating what the technology was capable of and accelerating the movement toward 3D in cinema. Once TI saw kids flocking to 3D movies, the company began to target the education market. Another factor influencing the move was TI's discovery that it could add DLP to existing 2D machines at little of no extra cost. Knowing that districts wouldn't have to pay a premium for 3D-ready projectors enabled the company to pursue what might be called a Field of Dreams strategy--if we build it, they will come. TI figured if it provided the schools with the technology, then the content providers would quickly follow suit with the content to exploit it. …" @default.
