Developed by Sandra Dillon, Director of the Multisensory Language Training Institute of New Mexico, Sounds In Syllables (SIS) is the most powerful Orton-Gillingham approach to teaching reading (decoding, fluency, and comprehension), spelling, writing, and the foundations of syntax and grammar. In developing SIS, Ms.Dillon incorporated teaching methods she learned directly from Patricia and Charles Lindamood, Beth Slingerland, and Aylett Royal Cox, author of Alphabetic Phonics. These methods integrate evidence-based practice from neurology, cognitive sciences, psychology, speech-language pathology, and linguistics to produce the most durable remediation for students with even the most severe learning disabilities.
Academic Therapists learn the precise articulation of the sounds of English and sound-symbol relationships. They learn to "cement" learning by using multisensory methods that trigger positive changes in the way students process learning. Research on these strategies demonstrates that multisensory approaches delivered through the repetitive, simultaneous, methods of SIS actually strengthen weak neural pathways and build new ones. This is why SIS students retain the reading and language skills they learn in order to achieve academic success long after they have completed their work with ASDEC therapists.
