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…

The author has worked as a language teacher, teacher educator, and second language acquisition (SLA) researcher for over forty years. During this time grammar has figured largely in his thinking, in part because it has traditionally been so central to language pedagogy and in part because he became fascinated with how the human mind grapples with…

Various positions regarding the Second Language Acquisition (SLA)-Language Pedagogy (LP) nexus have been advanced. Taking these as a starting point, this article will examine the nature of the SLA/LP relationship both more generally and more concretely. First, it will place the debates evident in the different positions regarding the relationship…

Examines the role of form-focused instruction (FFI) in developing implicit knowledge by reviewing 11 studies that have examined the effect of FFI on learners' free production. Suggests that FFI can contribute to the acquisition of implicit knowledge and points to two variables that appear to influence its success--the choice the th target…

Reviews research that addresses how grammar can best be taught in terms of four theoretically motivated instructional options: (1) structured input; (2) explicit instruction; (3) production practice; (4) negative feedback. (Author/JL)

The study of how learners acquire a second language (SLA) has helped to shape thinking about how to teach the grammar of a second language. There remain, however, a number of controversial issues. This paper considers eight key questions relating to grammar pedagogy in the light of findings from SLA. As such, this article complements…

A number of theories of second language L2 acquisition acknowledge a role for explicit L2 knowledge. However, the testing of these theories remains problematic because of the lack of a widely accepted means for measuring L2 explicit knowledge. This article seeks to address this lacuna by examining L2 explicit knowledge from two perspectives.…

Examines whether communication occurring in a second-language classroom setting sufficiently ensures development of full target language competence. The ability of 2 English-as-a-Second-Language students to "request" in English was followed over 15-21 months. Results indicated that the classroom did not provide the conditions necessary…

Discusses the L1=L2 hypothesis which states that, all other things except knowledge of language being equal, first language acquisition is the same as second language acquisition. Reviews the evidence for and against the hypothesis, looks at current research and considers the general distinction between formal and informal learning. (SED)

An exploration of second language acquisition research's traditionally separate focus on learners or learning, covering the development-as-sequence model, the development-as-growth model, learning style, cognitive orientation, and affective orientation, argues that a "whole" approach to language teaching must consider both the structural nature of…

This article examines four sets of factors that may potentially affect the incidental vocabulary acquisition from oral input of second-language (L2) learners. These include the intrinsic properties of L2 words; the nature of the input; the role of interaction; and individual learner factors. (Contains 85 references.) (MDM)

A problem facing investigations of implicit and explicit learning is the lack of valid measures of second language implicit and explicit knowledge. This paper attempts to establish operational definitions of these two constructs and reports a psychometric study of a battery of tests designed to provide relatively independent measures of them.…

Responds to a previous article that attacks variabilists' accounts of second-language acquisition (SLA) by addressing the following issues: (1) the context dependency of theory in SLA research; (2) the competency performance distinction; (3) the problem of data in SLA research; and (4) explanations of SLA. (Author/VWL)

This article examines the concept of simplification in second language (SL) learning, reviewing research on the simplified input that both naturalistic and classroom SL learners receive. Research indicates that simplified input, particularly if derived from naturally occurring interactions, does aid comprehension but has not been shown to…

This article examines a variety of options for conducting investigations of the effects of interventionist form-focused instruction (FFI). Constructs related to three key areas of form-focussed instruction are presented; (1) the type of instruction, (2) the target of the instruction, and (3) the definition and measurement of "language…
