This commentary discusses some theoretical and methodological issues related to research on the spacing effect in second language acquisition research (SLA). There has been a growing interest in SLA in how the temporal distribution of input might impact language development. SLA research in this area has frequently drawn upon the rich field of…

Classrooms the world over are full of people who, for different reasons, are learning additional languages and/or are studying through languages that are not their first. Gaining insight into such contexts is complicated for researchers and practitioners alike by the myriad of contextual variables that come with different implementations and make…

Lorenzo "et al". (2010) attribute some quite astounding average FL language score differences between Content and Language Integrated Learning (CLIL) and non-CLIL groups in Andalusia, Spain, precisely favoring the CLIL initiative. However, there are a number of methodological research questions that jeopardize any verifiable conclusions…

Great diversity exists in the way English is being used in the world today. It is now not uncommon to hear a Korean and a Brazilian do business in English, or a Syrian and a Norwegian debating politics in an English-speaking chat room. As opportunities to use English increase and evolve, researchers are left with the difficult challenge of…

Within the growing body of work that is sometimes labeled CA-for-SLA, there is a need for more research with longitudinal data. Hellermann and Cole (2009) provide a valuable contribution in this area. However, in doing so, they also make use of an exogenous theory of learning, situated learning theory (Lave and Wenger 1991), and its associated…

This article proposes that a complex issue such as bilingualism gives rise to a need for complex research. Complexity theories, both in the psycholinguistic and educational fields, may inspire new empirical studies on bilingualism that will likely provide data otherwise unattainable through classic pre-test/post-test methods. The article also…

In his recent Forum article on ideology in applied linguistics, Alan Waters (2009) takes up arms against what he perceives as a damaging critical tendency. Ideas about language teaching, he claims, are promoted (e.g. learner centredness) or proscribed (e.g. artificial texts) "on the basis of ideological belief rather than pedagogical value". By…

It is a good practice to try to understand matters at hand by first stepping back and adopting an historical perspective, which I will begin this review by doing. Next, I will take up the challenges that each of the authors in the articles in this volume has presented for the study of complexity, accuracy, and fluency (CAF) in second language…

In accord with the general program of researching factors relating to ultimate attainment and maturational constraints in adult language acquisition, this commentary highlights the importance of input differences in amount, type, and setting between naturalistic and classroom learners of an L2. It is suggested that these variables are often…

Authenticity has been a part of the intellectual resources of language teaching since the 1890s but its precise meaning and implications are contested. This commentary argues for a view of authenticity which recognizes the limits of the concept as a guide for pedagogic practice and acknowledges the fact that texts are processes rather than…

This article critically scrutinizes a number of issues involved in the definition and operationalization of complexity, accuracy, and fluency (CAF) constructs. It argues for maintaining clearer distinctions between CAF, on the one hand, and notions such as linguistic development and communicative adequacy, on the other. Adequacy, in particular,…

In Waters (2009), it was contended that, because of its ideological orientation, a good deal of applied linguistics for language teaching (ALLT) fails to "mediate relevantly" between academic and practitioner perspectives. James Simpson's rejoinder to my article (Simpson 2009) attempts to refute its claims. However, in my view, it fails to do so,…

Owing to analyses of large spoken corpora the linguistic knowledge of conversation has grown in recent years exponentially. Up until now little of this knowledge has trickled down to the EFL classroom. One of the reasons, this paper argues, is the failure in the relevant literature to spell out clearly how teaching conversational grammar affects…

This article is a response to Sheen and O'Neill's (2005) critique of our paper entitled "Teachers' stated beliefs about incidental focus on form and their classroom practice" (Basturkmen et al., 2004). In addition, it seeks to clarify a number of common misunderstandings about focus on form (e.g. that "form" refers exclusively to grammar and that…

Responds to a previous article criticizing the variation models of second-language acquisition (SLA), and argues that the variation models can and do explain (SLA) and that any adequate model of SLA should take interlanguage into account. (Author/VWL)
