I have had several people ask about what written expression is and as a parent what can they do about it. Well here goes.  Written expression is an expressive language problem. This is when the individual has difficulty expressing themselves through writing.  Many times these people are very articulate when the speak verbally and they can sound great (fluent) when they read. All too often they do not comprehend much of what they read. Unfortunately, they cannot seem to get their thoughts down on paper. (Some students have told me that it is just blank in their heads and they just don't know how to get started.  Procrastination seems to take hold here and many times never leaves, even into adulthood.) Therapies where multi-sensory approaches are are used are very effective for this population.
