1. The students in an eighth-grade class represent a wide range of levels of cognitive development, from concrete operational to formal operational though. The teacher's best strategy for adapting instruction to accommodate this degree of cognitive variation among students would be to:
make use of experiential and hands-on activities to complement and illustrate more abstract content.
group students as much as possible according to level of cognitive development.
plan to work with students one-on-one to the greatest extent possible.
target instruction at the average level of cognitive development represented by the class overall.
