Documents 20 years of second-language acquisition research, highlighting two subthemes involving the alternate broadening and narrowing of research perspectives and predicting that the next phase of research will unite the historically distinct research foci on learning and the learner. (209 references) (CB)

Reviews the conceptual, curricular, and empirical bases of task-based language teaching and suggests future trends, concluding that the conceptual and empirical bases need to be extended both substantively and methodologically. (38 references) (CB)

Origins and problems of classroom-centered research on language learning and teaching are surveyed, tracing the development of both the concerns and the research tools used. The development of a productive controversy over objective versus subjective methods is described. (MSE)

Presents observations on designing and implementing replications of applied linguistics research, focusing on a selection of research to be replicated, evaluation of the feasibility of replication, and benefits of replication. (CB)

Clarifies and defines quantitative research as it is applied to the study of language acquisition. Trends in the use of quantitative and nonquantitative methods in applied linguistics are reported, and suggestions are made concerning useful paradigms and procedures for further research in language acquisition. (Author/CB)

Listings of over 200 graduate theses and dissertations in English as a second language (ESL) completed since 1975 were studied to determine apparent topic areas and methodologies. (Author/RM)

Considers both qualitative and quantitative research approaches on second language learning, with focus on second language classroom research. Concludes that both approaches are relevant to determining the important variables to investigate and the relationships those variables have to second language learning outcomes. (Author/CB)

Limitations of language acquisition research are: the restricted linguistic scope of studies; lack of data in cognitive processes and learning strategies, the role of individual variables, second language acquisition, and the role of social and environmental variables; and undeveloped methodology for data collection and data analysis.
