In this memorial volume for A. Ronald Walton, two normally separate domains are interrelated: the formation of language policy and the improvement of language teaching. Bernard Spolsky, Elana Shohamy, Joshua Fishman, and Kees de Bot address theoretical aspects of national language policy. John Trim relates the historical development of the Council of Europe’s international language policy. Richard Lambert, Ronald Walton, Richard Brecht, and Xueying Wang deal with structural issues in language instruction in the United States. Eleanor Jorden, Galal Walker, Myriam Met, and Gilbert Merkx discuss the special problems of providing instruction in the non-Western languages. And Michael Long, Ross Steele, Ralph Ginsberg and Laura Miller are concerned with specific pedagogical issues: task-based language teaching, the role of culture in language instruction, and what is learned during study abroad.
