What Does Evidence-based Intervention Look Like?
Evidence-based reading refers to approaches that have been supported by independent research studies. The most well known approach to reading intervention for dyslexic students is called Orton-Gillingham (OG). There are several programs that follow an OG approach but it is important to make sure that the program your child will be using his truly hitting all components of OG instruction.
It is also important to note that different "OG Programs" are better suited for different age groups or learning profiles. Orton-Gillingham can begin at a pre-K level but of course the instructional techniques and scope of the program would be quite different. The most important aspects of good OG intervention are:
It’s systematic and sequential – It builds on itself from the basic concepts to more complex concepts and follows a logical order frequently revisiting previously taught concepts.
It’s explicit – Every concept, sound pattern, and strategy is taught directly through specific procedures and it is not assumed that a child knows or will pick up on these concepts on their own.
It’s diagnostic – Every child learns things at a different pace and needs more or less practice than another child to master specific concepts. This instruction meets each child in his or her own place by working with the strengths of the child to overcome the weaknesses. This requires a great deal of data collection in every session.
