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)

A critical examination of grammaticality judgment tasks in second-language acquisition research focuses on the theoretical assumptions underlying such tasks and describes an investigation indicating that grammaticality judgment tasks elicit a particular kind of performance that needs to be better understood before being used as a basis for…

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…

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…

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…

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.…

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 reviews previous studies of the effects of implicit and explicit corrective feedback on SLA, pointing out a number of methodological problems. It then reports on a new study of the effects of these two types of corrective feedback on the acquisition of past tense -ed. In an experimental design (two experimental groups and a control…
