Hmm, you seem to have changed your position now on the question of ability, so I guess we are in agreement on that.
Obviously, if kids start with different ability levels, then no matter what teachers do, the gap will remain, regardless of how much more money we spend on education
George, you’re going to have to be more clear on what you mean by ability. Are you referencing a particular norm in learning and behavior? Given a standard, say teachers with the same ability and classrooms with the same equipment to educate a student the outcome may be changed by the capacity of the student to learn. But it’s not that simple. There are just too many variables. Many of which I outlined in earler posts. Of course therre will always be anomolies that wil lead to differences in learning which may create the “gap” you mention, whatever that is, but the aim of education is universal. All students can learn to the BEST of their ability. that is the true aim of education, not just for the elite or the inherentely intelligent. It gives the student the opportunity to learn how to learn and become a useful and productive citizen.
