What an excellent point to bring up... there are many school districts who are being forced by the federal government to answer that question. My personal idea of how it happens is at the point of the teacher referral. If a teacher thinks that a student has problems, they refer them for special eduation testing.
If the teacher things that they can help them, they are less likely to refer them. If a teacher thinks there are problems he/she can't handle in the classroom, they refer them for special education. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
