I see a huge difference in my ESL students who use electronic dictionaries versus traditional dictionaries. The electronic ones are fast, but they don’t see as many words. They don’t see variations on a root word.
With a paper dictionary, students browse. Sometimes, instead of reading their novel during silent reading, they want to read the dictionary.
E-books and computers have a place in education and daily living, but they cannot replace paper books.— Carol
Democratic Group's Proposal: Give Each Student a Kindle
If I had to bet, I would bet this teacher is right. I do lots of reading on screen (which produces eye strain, a problem Kindle technology is intended to solve), I do some reading on an iTouch, and I expect to do lots of reading on my factory-refurbished Kindle.
But I don't expect to see books disappear -- especially not textbooks.
