Laptops make it easier for students to edit their copy and make changes without getting writer's cramp, he said. As a result, students are writing and revising their work more frequently, which leads to better results. And it's important, Silvernail said, that those skills translated when the test was taken with pen and paper, too.

In 2003, there was a study that showed that all this writing online was actually making kids <a href="http://www.techdirt.com/articles/20030520/1943254_F.shtml">more comfortable</a> with writing in general. In 2004, a study showed (like this one) that with a little instruction kids easily <a href="http://www.techdirt.com/blog/wireless/articles/20041223/1427218.shtml">understood the difference</a> between texting and writing. In 2005, a study actually found that kids were <a href="http://www.techdirt.com/articles/20051031/1836235.shtml">better writers</a> than in the past "using far more complex sentence structures, a wider vocabulary and a more accurate use of capital letters, punctuation and spelling" even if they sometimes let a txtism into their writing. And, in 2006, a study showed that students showed <a href="http://www.techdirt.com/articles/20060731/1938242.shtml">no ill effects</a> from widespread text and IM messaging.
