I want to address this last part
Teaching should concentrate on the slow students and the so called "gifted" could assist the teachers with the slower classmates. The slower students can catch and even surpass the faster students, if given enough time.
How does this sound?
This is in essence saying that we should choose to educate some students and not others. It�s asking a student to do the teacher�s job, a job we require teachers to spend a number of years training for. We need to find ways to support at risk students that don't involve sacrificing another child's learning potential in the process. It is not okay to sacrifice any child's learning potential.
