It also means that sooner or later most kids will encounter a learning situation for which they are not optimally wired. Most of us can probably name someone who had a tough time during the school years but went on to become an incredibly successful adult. We have an intuitive understanding that those kids who are not especially adapted to excelling in school can, nevertheless, become highly accomplished adults in their chosen niches. We also know that as adults we're allowed, if not encouraged, to practice our brain's specialties. Yet we expect school-aged kids to be rather good at everything.
Some kids are.
Most kids aren't. This expectation can have traumatic effects on students. It is critical, therefore, in an effort to preserve and protect these kids' minds, that we adopt a developmental perspective when evaluating a student's strengths and weaknesses. In the adult world it's the strength of your strengths not the weakness of your weaknesses that really counts. Helping kids get better and better at what they are good at makes a lot of sense.
