48 This Task Force [or its successor] might consider developing principles and preferred guidelines to support the creation of instructional materials and the implementation of a state-supported program of teacher training. Examples: A. A balance should exist between the negative and positive aspects of this joint history and teacher training should emphasize this balance. B. The "Contributionist" model should avoid perpetuating messages of grateful servitude or delighted productivity by enslaved Africans. C. Both the brutalities of master dominance and the bravery of slave endurance should be treated with candid sensitivity. D. In the classroom, wherever most effective, instruction should be mataerials/media centered and not teacher focused. E This program of education enhancement has to be considered as a multi-stage endeavor requiring several years of activity by those involved. The existence of this Task Force might be seen as Stage One.
