In empirical applied linguistics research it is essential that the key variables are operationalized in a valid and reliable way, and that the scores are treated appropriately, allowing for a proper testing of the hypotheses under investigation. The current article addresses several theoretical and practical issues regarding the use of measurement…

Argues that the most productive future directions for theory building and research in applied linguistics derive from the extent to which the field's investigators can enrich their conceptual framework and methods with insights from "constructivist" scholarly approaches. Focus is on three arenas in which such approaches and additional scholarship…

Responds to a previous article on constructive and constructivist challenges for applied linguistics. (Author/JL)

Reviews the history of applied linguistics together with the history of the journal "Language Learning," indicating the journal's particular place in that larger history and honoring its 50th anniversary. (Author/JL)

Responds to a previous article on research in second-language learning, challenging the need for discussion on the promises and problems, and asserting the need to report definitive results. (Author/JL)

Discusses the fundamental problems within speech act theory, focusing on the extent that these problems undermine attempts to apply speech act theory in the field of language pedagogy. (96 references) (Author/OD)

In response to a previous article (Bialystok) on perspectives on the development of applied linguistics, this article begins by adding its own perspectives to what has already been offered. The article concludes by discussing the research agenda for the future. (Author/JL)

Focuses on one particular psychological dimension, extraversion-introversion. The relatively small number of linguistic studies in which extraversion is focused on as an independent variable suggests that applied linguists believe it unrelated to speech production or language learning. Argues that this suspicion is based on a misunderstanding…

Reviews research on student motivation for second-language learning from the standard applied linguistics approach. The utility of other concepts of motivation to such research conducted at the micro, classroom, and syllabus levels is discussed as well as informal, out-of-class, and long-term factors. (188 references) (Author/CB)

Argues that further progress in applied linguistics and second-language acquisition will be achieved through collaboration with researchers in other fields. Three examples of research problems are provided that would profit from collaboration with applied linguists: the definition of language proficiency, the neural basis of language functioning,…

From perspective of a psycholinguist, discusses three leading questions that have arisen from foundational, descriptive second-language-acquisiton studies: Why are certain L2 constructions learnable and others not?; In considering input requirements, is it fair to say that adult learners can take advantage of metalinguistic information about the…

A study of children's acquisition of synonymy as a sense-property during the second childhood period (as defined by Piaget) suggests that, contrary to psychologists' claims, nominal realism is a linguistic phenomenon that should be studied as such. (75 references) (Author/CB)

In this longitudinal study in which a second language was used as the sole or major medium of instruction, the experimental group performed as well as or better than the control groups with respect to language skills, academic skills and cognitive development. Pupils could also communicate effectively in their second language. (AG)

Conflicting evidence regarding listening comprehension as a separate trait in language proficiency is reviewed. Two studies conducted in Japan are presented that use the multitrait-multimethod methodology to examine the construct validity of the listening trait. (74 references) (Author/LB)

Raises three questions concerning the present state of second-language acquisition research: (1) What has it achieved for language teaching? (2) How close is a theory of second-language acquisition? (3) What is its status within the chorus of disciplines that deal with language? (Author/JL)
