The nine papers presented here treat the implications for language teaching arising from the fundamental notion that personal growth, cultural development and international communication are three interwoven elements of human progress. The papers are organized as follows: (1) an introductory chapter on language learning for cultural development and international communication, focusing on instructional objectives in the context of general educational goals; (2) language contact in a multicultural context, emphasizing the relationship between diglossia and bilingualism, interference and language attitudes; (3) contrastive psycho-sociolinguistics and language teaching, including a discussion of error analysis and pedagogical implications; (4) psychological and socio-educational aspects of bilingual and multicultural education; (5) language varieties, language levels, language for special purposes and individual differences; (6) curriculum organization and interdisciplinary information; (7) language teaching strategies, particularly formal grammar-translation and reading approaches, various functional approaches, and an integrated approach; (8) language teaching tactics, techniques, procedures and aids; and (9) the expansion of research in second-language teaching. Each section contains a bibliography. (AMH)
