Deals with several related problems of language contact, approximative systems, and language learning situations. Proposes the recognition of "fixed approximative languages" in relation to learning situations. (Author)

An attempt to refute the opinion that true bilingualism is acquired only in early childhood. The discussion arises from experience with bilingual adults. The results of the study lead to recommendations on the production of materials for the teaching of foreign languages. (Author/AMH)

Proposed a model of first and second language learning within a communicative approach. (AM)

Tests to discover the nature of the second language learner's language are discussed. Such tests are based on the assumptions that the development of the system of the foreign language in the learner follows certain regular patterns, and that the learner's grammar is essentially systematic at any stage of his learning. (RM)

Supports and expands upon S. P. Corder's theory that all the utterances of a language learner are well-formed and appropriate. (PMP)

This article describes a series of experiments concerning the relationship between cognitive processes and learning a second language. Similarities and differences between first language acquisition and second language learning by children and adults are discussed. (CFM)

Earlier version of this paper was read at the Second International Congress of Applied Linguistics, Cambridge University, Cambridge, England, in September 1969. (VM)

Explores the problem of implicit and explicit knowledge in a second language. The theoretical characterizations of Bialystok and Krashen are shown to be unsatisfactory in addressing these two problems. Some characteristics of explicit knowledge that any improved theory should be able to explain are considered. (SED)

Presents data which indicate that the language learning capability of adolescents and adults who are acquiring a second language differs from that of children who are acquiring their native language. Discusses consequences for second-language teaching methodology. (EKN)

A description of a study which tried to establish the sequence of language development in a language other than English (Farsi) and to measure the syntactic complexity of the first language against that of the second. Results indicate a direction toward the construction of better course materials and tests. (AMH)

The development of German proficiency by a three-year-old Australian boy living in Germany was monitored for a five-month period. His command of German negation is reported. The study is seen as bearing on issues in first and second language acquisition, such as competence and interference. (JB)

Language learning and language teaching are discussed in terms of H.E. Palmer's theory that language can be divided into primary matter (units learned by heart integrally) and secondary matter (units built up or derived by the pupil from primary matter). Excerpts from the "Nuffield German Teaching Materials" are used to illustrate how…
