Grades 9-12 Tips from Ellen Addressing Change Classrooms that address reform mathematics look very different from classrooms of not too long ago. As teachers address the changes in how they teach, they do not have the same models on which to rely. Nothing can be taken for granted.
Problem sets no longer provide the type of practice that is needed.
Old tests and exams become outmoded. Tutors and parents may not be equipped to serve as resources. Instruction has to be resequenced, with some old favorite topics and activities giving way to new. The things that we were good at, that were comfortable, may no longer have a place in the reform classroom. Change becomes more difficult when there is little to model after.
