Sequential Spelling (SS) was developed by Don McCabe, president of the AVKO Educational Research Foundation. Don is a dyslexic and former school teacher who developed this curriculum with the specific intent of teaching spelling in a manner that would accommodate the learning needs of dyslexic students.
Rather than focusing on the phonograms, rules, and exceptions of spelling, SS teaches students to spell based on patterns. Spelling patterns are systematically introduced and then repeatedly reinforced through spiral review. To this end, great emphasis is placed on building words from their roots to expanded forms.
Sequential Spelling can be used in any educational setting whether for classroom, small group instruction or one-on-one tutoring. AVKO has placed demonstration videos on their website which further explain the program and model instruction.
