This article presents a review of research that has investigated ways of measuring implicit and explicit knowledge of a second language (L2), focusing on grammar. It begins by defining implicit and explicit knowledge in terms of a distinguishing set of criteria. Two ways of investigating implicit knowledge are discussed -- through experimental…

Studies on oral corrective feedback have been mainly directed towards cognitive factors. Practical aspects of error correction have been ignored to a large extent. The present study attempted to fill this gap by investigating teachers' practice and beliefs about oral error correction and the priorities they set for themselves and comparing the…

Recent findings in the field of pragmatics have revealed that pragmatic accuracy (knowledge) and pragmatic speed (processing ability) function as two distinct and non-parallel components of pragmatic competence. Anderson's adaptive control of thought--rational (ACT-R) model, which emphasises the development of skill through repeated practice,…

This article reports on a study which investigated the effects of correction of learners' grammatical errors on acquisition. Specifically, it compared the effects of timing of correction (immediate versus delayed correction) and manner of correction (explicit versus implicit correction). It also investigated the relative effects of correction of…
