The Square root rule

I’ve been doing a lot of research and reading about dyslexia and came across an absolutely amazing book that has just changed my whole understanding of dyslexia. Its called The Dyslexic Advantage: Unlocking the Hidden Potential of the Dyslexic Brain

There are some many insightful chapters about the nature of the dyslexic brain including one that explains how difficult it is for dyslexics to undertake procedural learning i.e. learning how to do something, and learning it to the point where it is automatic, so you know how to do it instinctively.

The authors, Brock Eide and Fernette Eide, have coined something that they refer to as the square root rule based on lots of research.

The rule essentially gives the following guide: it takes the square root longer to learn something if you are dyslexic than if you aren’t. So if its takes 10 hours for a person without learning difficulties to learn something, it would effectively take a dyslexic 100 hours to learn the same task. Sobering!

I practically shouted “Aha” loud. You see now I understand even more deeply why spelling patterns are a challenge, why times tables are a challenge and indeed why concepts come quickly to my daughter and then seem to disappear just as fast. Indeed, now I fully understand what is meant when they say repetition is the most critical of the learning strategies.

I understand also that my daughter is not pretending and also, that the concepts will eventually stick. We just need to keep at it.
