This is the VOA Special English Education Report, from http://voaspecialenglish.com | http://facebook.com/voalearningenglishDyslexia is a problem that interferes with the ability to recognize words and connect sounds with letters when people read. People with this learning disorder may also have problems when they write. Dyslexia is not related to eyesight or intelligence. The problem involves areas of the brain that process language. Brain scientists are studying whether they can predict which young children may struggle with reading, in order to provide early help. John Gabrieli at the Massachusetts Institute of Technology is leading a study of five-year-olds in about twenty schools in the Boston area. He says,"We partner with schools that have kindergartens. And in this study what we do is, for all the children whose parents permit them to participate, we give them a brief set of paper-and-pencil tests to look at which children appear to be at some risk for struggling to read." So far, fifty of the kindergarteners have been examined in a machine that shows brain activity. The goal is to study five hundred children using fMRI, or functional magnetic resonance imaging. The scanner uses a high-energy magnetic field and radio waves to "look" inside the body. Written tests are not always able to identify dyslexia or other problems. Professor Gabrieli says children can differ a lot in their abilities from day to day. He says brain scans may offer a more scientific way to identify problems. And with reading problems, he says, early identification is important. "All the literature is that for intervention, behavioral programs, educational programs that help children overcome reading difficulties, the younger the child, the more effective they are."Reading problems are not usually identified until a child is in the third or fourth grade. The longer the wait before children are recognized aspoor readers, he says, the less these interventions can help. And, as Professor Gabrieli points out, poor reading can make education a struggle. "Reading is -- everything. Even math and science have textbooks." During the brain imaging, the children are given tasks related to reading. They work with letters and sounds of language. The brain scans measure the extent to which certain parts of the brain become active while the children do the work. The neuroscientists say they are pleased with the early results, but still have a lot more work to do on the study. For VOA Special English, I'm Mario Ritter.
