"The Wilson Reading System® is a reading and spelling program originally developed for students with language-based learning disabilities, such as dyslexia, in mind. It's designed for students in grade two through adults who have not succeeded in learning to read with traditionall methods. The system uses multi-sensory learning, activating visual, auditory and kinesthetic-tactile pathways to enhance memory and learning of written language."
"Orton–Gillingham was the first teaching approach specifically designed to help struggling readers by explicitly teaching the connections between letters and sounds. ... It also pioneered the “multisensory” approach to teaching reading, which is considered highly effective for teaching students with dyslexia."
