Idealization plays a fundamental role in scientific inquiry. This article examines the case for maintaining the claim that the second language acquisition (SLA) of grammatical structures such as negation manifests identifiable stages of acquisition. It proposes that, while research has demonstrated the need for de-idealization, there is no need to…

This article reports a meta-analysis of studies that investigated the relative effectiveness of comprehension-based instruction (CBI) and production-based instruction (PBI). The meta-analysis only included studies that featured a direct comparison of CBI and PBI in order to ensure methodological and statistical robustness. A total of 35 research…

The present meta-analysis examined the overall average correlation (weighted for sample size and corrected for measurement error) between passage-level second language (L2) reading comprehension and 10 key reading component variables investigated in the research domain. Four high-evidence correlates (with 18 or more accumulated effect sizes: L2…

Argues that facts of phonological and morphological interference can be satisfactorily accounted for only by a theory that treats local, morphologically dependent alternations in the morphological component of the grammar and global automatic alternations in the phonology with phonotactically motivated repair mechanisms and not with what are…

Reviews research findings on second-language (L2) interaction from the perspective of syntactic development. The article argues that better understanding of the role of negotiated interaction in L2 syntactic development requires examining the specific grammatical structures in interaction guided by the criteria of relevance, availability,…

Reviews research that has been emerging from the availability of corpora on the grammar of spoken English. Presents arguments for the view that spoken and written language utilize the same basic grammatical repertoire, however different their implementations of it are. (Author/VWL)

An examination of second-language acquisition research assumptions argues that second language data are important to understanding the nature of language. Exploration of theoretical underpinnings and empirical evidence relating to language universals indicates that research must consider how disparate facts of language are conceptually related…

Examines the changes in how researchers perceive the relationship between theories of language and theories of language acquisition. It is determined that a theory of grammar is a necessary component in native language acquisition and may also be required for second-language acquisition. (Author/CB)

Discusses the theory that the second-language processing of subordinate clauses and of anaphora is affected by the basic word order of a learners native language. This phenomenon, believed to be a prediction of universal grammar, is explored. (54 references) (Author/VWL)

Discusses the current approaches to interlanguage syntax, focusing on the goal of finding consistency and pattern in syntactic variation. Some themes contributing to descriptive approaches include: the transition from morphosyntax acquisition studies to those of more complex syntax, the emergence of syntax from discourse, explicitness, and the…

Provides an historical sketch of form-focused instruction research, defines what is meant by form-focused instruction, and discusses the main research methods that have been used to investigate form-focused instruction in terms of a broad distinction between confirmatory and interpretive research.
