Within diverse and otherwise heterogeneous classrooms the children need to receive various approaches to instruction and varieties of instructional grouping. Thus, the focus is on appropriate academic stimulation for every child, with consideration of different learning styles. It is clear that there is no one way, no silver bullet, in teaching children. They deserve the best of differentiated instruction. A good image to portray optimal teaching was used by Mortimer Adler at an inservice gathering for teachers.
All children have different capacities for learning.
Some are pints, some are quarts, and some are gallons. We should not fill the pints with skim milk, the quarts with whole milk, and the gallons with cream. Everyone must receive cream. The best curriculum for all children is one that includes all six of Bloom's educational objectives, all the time, and preferably beginning with evaluation because it requires all the others. The best curriculum for all children is the curriculum for the gifted.
