I have been a bit puzzled by the claims that a particular program and a particular type of program get students over the finish line much more quickly than Orton-Gillingham does, and it took me a minute (or more) to figure out why that might be true or why people think it is true. Well, it comes down to mastery practice vs distributed practice. OG does NOT require mastery before teaching new material!
The Orton Gillingham approach, or technique as Ms. Gillingham (1960) referred to it as, has an expectation that "... we introduce new letters, not more than one or two a day...", although she did include exceptions. The daily lesson included practice of the letters taught so far. One could infer that the practice section of the lesson plan could be voluminous. Neither in the 1960 version nor the one edited 37 years later was there any mention of mastering one element before moving to a new one.
Somewhere along the way, it must have occurred to someone that the length of a lesson could become overwhelmingly long once students progressed through a great number of sound/symbol combinations and that practice should be limited. My early training was influenced by Language Tool Kit written by Paula D. Rome and Jean S. Osman and Arlene Sonday's Workshop Manual: The Orton-Gillingham Approach to teaching Reading, Writing, Spelling and the many Fellows who provided training at the NY(C) Branch of the Orton Society/IDA - unfortunately disbanded by a former president. Nowhere can I find any reference to mastery practice before moving on. The lesson plan that I adopted includes 12 days of practice in the first 4 parts of the lesson plan before teaching new material EVERY lesson! Some lesson plans include even less practice than that. Twelve days of targeted practice seems to meet the needs of most students.
Orton-Gillingham is getting a bad rap because some training program(s) are telling their trainees that students must attain mastery of each new concept before moving on to teaching anything new. No wonder it is taking students so long to reach proficiency in more complex material and students being taught with other programs are sailing ahead. Mastery practice is not an Orton-Gillingham thing! A particular program that requires it has notoriously been earmarked by slow progress and this is why. Mastery practice is not supported by research, so stick to the science. NO mastery is required before moving on to a new concept, just include practice while they learn new material. If a problem crops up, put the problem pattern back in the practice. If students don't need all 12 practices, drop the element.
While we are at it - Orton-Gillingham does not require sand, shaving cream or manipulatives - if you think these items are the kinesthetic element of OG, you have been sold a story. It is handwriting that is the necessary kinesthetic element (Orton preferred cursive). Anna was influenced by Grace Fernald and did recommend tracing letters, and Orton thought saying the letters out loud during spelling was helpful. I have never included either of those practices in my lessons, and students have performed well without them. Teach letter formation in kindergarten or preschool, if possible, before they learn bad habits.
STOP promulgating bad practices and blaming it on the Orton-Gillingham approach/technique.
