Included in this volume are the reports on foreign language research and development produced by the three working committees of the fifteenth annual Northeast Conference on the Teaching of Foreign Languages. Discussions of (1) the Indiana and Washington State programs, (2) "Artes Latinae," a complete project of programed learning materials for the first level of Latin, and (3) the two patterns of bilingual education employed in Dade County, Florida public schools comprise the report on innovative foreign language programs developed by the committee headed by Oliver Andrews, Jr. The group chaired by Seymour O. Simches compares the foreign language classroom, student, teacher, and instruction in 1898 and 1968. In the report on the achievement of liberated expression, the committee headed by Mills F. Edgerton, Jr. discusses (1) relevant psycholinguistic considerations, (2) desiderata and existing materials, and (3) reasons why the "semantic component" must be treated explicitly in formal foreign language instruction.
