In the late 1970s and early 1980s, Stephen Krashen developed Monitor Theory--a group of hypotheses explaining second language acquisition with implications for language teaching. As the L2 scholarly community began considering what requirements theories should meet, Monitor Theory was widely criticized and dismissed, along with its teaching…

From one of the leading figures in the field of second language acquisition and second language teaching, "While We're on the Topic..." offers an up-to-date overview of six principles underlying contemporary communicative language teaching. In a conversational style, Bill VanPatten addresses principles related to the nature of…

In this article, we challenge the notion that aptitude--operationalized as grammatical sensitivity as measured by the Words in Sentences section of the Modern Language Aptitude Test--is central to adult second language (L2) acquisition. We present the findings of a study on the acquisition of two properties of Japanese, head-final word order and…

This article reports the findings of a study in which we investigated the possible effects of word order on the acquisition of case marking. In linguistic typology (e.g. Greenberg, 1963) a very strong correlation has been shown between dominant SOV (subject object verb) word order and case marking. No such correlation exists for SVO (subject verb…

In this paper we report the findings of an experiment to test whether training via processing instruction transfers to output tasks. Two groups of Turkish L1-English L2 learners participated: one that received processing instruction on passive structures and a control group that did not receive any instruction on passives. A pre-test/multiple…

In the present study, we examine the roles of 1) explicit information about language provided to learners prior to treatment and 2) aptitude (specifically grammatical sensitivity) within Processing Instruction. Forty-two learners of Spanish in their third-semester of study were divided into two groups: those who received explicit information (EI)…

In this study, we examine explicit information and aptitude within processing instruction. Forty-six learners of German in their third semester of study were divided into two groups: those who received explicit information prior to treatment (+EI) and those who did not (-EI). Participants also took the grammatical sensitivity portion of the Modern…

Research on Processing Instruction (PI) has yielded consistently positive results across a variety of measures. In addition, in comparison to other instructional interventions, PI tends to yield superior results. The one difference is comparative research with Meaning-based Output Instruction (MOI) in which in a number of studies, MOI is seen to…

Responds to comments made regarding an earlier article written by the author on processing instruction in second language learning. (Author/VWL)

Reviews processing (PI) instruction, outlines a model of input processing, describes the nature of PI, and discusses research on it to date. (Author/VWL)

Reviews five major findings of language research about the effect of explicit instruction and relates them to second-language teaching and learning, covering such areas as the route of acquisition, psycholinguistic readiness, error correction, classroom versus nonclassroom learning, and access to comprehensible and meaningful input. (37…

In response to a published study of second-language input processing and processing instruction, a relatively new concept in language teaching, misinterpretations of theoretical and conceptual issues are pointed out and methodological concerns about the study are discussed. (MSE)

Attempts to determine whether or not explicit information given to second-language learners receiving processing instruction is responsible for the beneficial effects of instruction. Results indicate that these beneficial effects derived from the structured input activities and not from the explicit explanation provided to learners. (22…
