 Connecticut Longitudinal Study

Started in 1983 at the Yale University School of Medicine, the Connecticut Longitudinal Study identified 445 children entering kindergarten in various Connecticut public schools and tracked their progress for more than 20 years. Ninety percent of the study's original participants are still involved in ongoing research to study reading disabilities in adults. The initial results of this study were published in the  December 1999 edition of the Pediatrics journal of the American Academy of Pediatrics

  In 2003, Dr. Sally Shaywitz, the study's director, published her groundbreaking book Overcoming Dyslexia: A New and Complete Science-Based Program for Reading Problems at Any Level in which she provides a very readable, yet detailed summary of dyslexia: its history, its neurological origins, and how to successful diagnosis and address the disorder. While the book focuses primarily on the phonological reading aspect of dyslexia, it is by far the most important writing to date on this pervasive disorder.  

While the Overcoming Dyslexia provides a great amount of information, the following points should be of great interest to the average person:

  1. Approximately 1 out of 5 people have dyslexia to some degree, and thus may impact their ability to become quick, accurate, fluent readers. 

  2. Dyslexia can be SEEN in brain scan images using functional MRIs.

  3. Only 1/3 of children with reading disabilities are identified as such by public schools.

  4. Traditional special education interventions that do not include the essential elements needed to teach a dyslexic to read, fail to close the gap between a dyslexic and their peers. This gap is commonly referred to as the Matthew Effect.

  5. Very few cases of dyslexia-like reading disorders can be traced to inadequate introduction to reading skills at an early age.

    and finally:

  6. Research-based programs that implement the following essential elements have been shown to provide substantial and long-term growth in a student's ability to achieve reading success:

  • Focus on reading fluency , not just mastery

  • Focus on phonemic awareness 

  • Small Group Instruction

  • Consistency & Repetition

  • For school age children, integration with school services.

 

 

 

 

 

 

 
   
   
   
 
     


A fluent reader uses primarily the back-left part of the brain when reading. In the picture above, the red areas indicate brain activity in fluent readers
An impaired reader  uses primarily the front-right part of the brain. In the picture above, the red areas indicate brain activity in dyslexic readers
