Write Touch Screen Board, New School Facilities

In the United States the school board is being replaced to make it more interactive, giant, with a touch screen computer, which allows students and teachers to share tasks, surf the web and edit video using their fingers as pens, says Wired News. Chalk dust makes nails pain when used to teach.

Students use the board to demonstrate solutions to math problems, the children draw on the board with their fingertips and explain to classmates how they came up with their answers.

"It's really motivating," said Eliza Bang, the class teacher. "As a platform for encouraging group work, that's normal."

Teachers can display a slide-show or even a video. It is now possible to open a web page with information that is useful only in seconds.

Interactive whiteboards can be found in more than 150,000 classrooms in the U.S., and technology is also growing internationally, with presence in 75 countries

And there is so much ability to "naughty students" to show something that is censored on the big screen during a lesson!
