Nanotechnology and Closed Captioned videos: Improving opportunities for teaching science to ESL students
One of the critical issues in science education is teaching science to ESL students. As noted earlier, since nanotechnology is interdisciplinary in nature, it is not easily understood without a visual component. Nanotechnology requires a curriculum that deals with basic as well as applied sciences delivered through interactive learning environments (Uddin and Chowdhury, 2001).
Closed Captioned Video provides audio, visual and textual support for introducing related scientific concepts, teaching vocabulary in context, showing examples and non-examples, and viewing real-world applications of nanotechnology. The current disadvantage is the lack of video materials suitable for K-12 usage.
With the implementation of Federal Communications Commission legislation, the Telecommunications Act of 1996 in the United States requiring closed-captions for television and video programming, educators in America have the means to make Closed Captioned Videos available for K-12 classrooms.
