WILL E-READERS REPLACE THE CONVENTIONAL PAPER BOOK？
Kindles, Nooks and other e-readers are threatening the future of printed books. But reading itself may get a boost from the devices. For example, a study found that the kids felt better about reading after a course in which they used Amazon Kindles. The research is in the _International Journal of Applied Science and Technology._
For two months, 199 middle-school students in a reading improvement class in Texas had 15 to 25 minutes every day when they were free to read on the Kindle. In general, the students felt the device improved their reading ability. And they tended to enjoy using an e-reader.
They noted the ease of carrying multiple books in one device, and the feeling that reading was suddenly a high-tech 21st-century activity rather than a boring waste of time. And some low-level readers who might otherwise be embarrassed to be seen with a simple book liked keeping their peers in the dark about what title they were reading. In the old days, one had to use a fake book-cover to achieve that level of secrecy.
