For all its political appeal, President Nixon's proposed busing moratorium raises troubling questions for the nation's educators. Since 1954 they have been guided by the U.S. Supreme Court's historic ruling that "separate educational facilities are inherently unequal." Last month, amid the latest uproar over busing, Nixon proposed that Congress prohibit new busing and concentrate $2.5 billion on improving inferior schools. Apart from constitutional dilemmas, the Nixon stand immediately reopened two hard questions:
> Can substantial school integration be achieved without more busing?
> Can racially separate schools be made equal at any price?
