YOU might say it all started with spell-check. In the 1980s, with the introduction of word processing programs like WordPerfect, it became apparent that computerized proofreaders could come to the rescue of struggling spellers and bad typists. Thirty years later, an ever-growing array of assistive technology is available to help students read, write term papers and take tests. From pens that can remember to text that can talk, such technologies are now being held up as important tools for students with learning disabilities like dyslexia, dysgraphia (trouble writing) and attention deficit hyperactivity disorder.
“These technologies help level a playing field for individuals who would not be able to demonstrate their capabilities as learners,” says Brant Parker, director of learning and innovation technology for the Calgary Board of Education in Canada. In his district, at least 90 public schools are using Dragon Dictate, a voice-recognition program that does the typing for you.
Take the case of Michael Riccioli, who noticed that his teenage son was not comprehending a novel assigned in class. Mr. Riccioli transformed the book into an MP3 file using software called GhostReader, which scans texts and reads them aloud. His son listened to the file on his iPod while reading along. “All went well with his test on the book,” Mr. Riccioli says.
