That's what aids are for. Or in some cases, the teacher divides the classroom up according to learning levels. There he/she can spend the time where most aptly needed. It can be done, and it is where the teacher earns their money.
If the class is going to be divided according to learning levels, doesn't that sort of defeat the purpose? If a student requires an aide, doesn't that say something about the nature of this whole thing?
We simply cannot make everyone equal no matter how hard we try. Unfortunately, what we CAN do is drag down the majority to the level of the minority, and that's what appears to be happening in schools. I frankly don't care how hard a life the teacher has trying to ride herd over academic anarchy, but I do care about the result on the kids, and if a teacher is spending huge amounts of time on one or two kids, the rest HAVE to suffer in their education.
Totally disagree. When I was student teaching, my teacher taught me the diagnostic prescriptive method, where classes are divided, in her case, into three distinct levels of learning. She was aptly able to manage all levels, but it required a little extra effort. No one suffered. She spent much of her time with those with learning disabilities and expected the smarter students to work independently. She was available at all times for any problems that came up. She taught ALL her classes this way and was very successful. She proved and measured her success with outake and intake assessments. Again, every student got their academic needs met in her classroom.
