Educators often create whole lessons that are really aimed at just one or two kids in the class. A teacher knows that a child needs to 'crack', something before they can progress to higher knowledge and rather than single the few children out, a whole class exercise will do the job. And the reality is that the consolidation and sense of mastery for the rest of the class will be no bad thing, extension activities and giving out 'expert', roles will ensure that everyone gets something out of the activity.
We have been guilty of making apps with just those one or two members of the class in mind. Writing apps designed for dyslexia support but useful for all, and now pocket playground, a fun play toy designed for children with social communication difficulties.
Aiming for the 'edges', the non-typical, the neuro-diverse is not a sensible marketing strategy, but hopefully it is a good educational one.
