In response to calls for an assessment tool that provides a separate performance dimension from the linguistic quality-oriented measures of complexity, accuracy, and fluency (CAF) and guided by systemic functional linguistic (SFL) theories, this study introduces a set of fine-grained objective measures of communication/content/function…

Measuring lexical diversity in texts that have different lengths is problematic because length has a significant effect on the number of types a text contains, thus hampering any comparison. Treffers-Daller et al. (2018) recommended a simple solution, namely counting the number of types in a section of a given length that was extracted from the…

A large data set of L1 psycholinguistic norms (Balota "et al." 2007) was used to assess spoken L2 English lexical proficiency in cross-sectional and longitudinal learner corpora. Behavioral norms included lexical decision and word naming latencies (i.e. reaction times) and accuracies for 40,481 English words. A frequency measure was…

This article is a conceptual and methodological exploration of a new construct, task interactional difficulty, and of a possible approach to assessing task demands in general. After arguing for the use of 'task difficulty' instead of 'task complexity', the notion of task interactional difficulty is analyzed, first by reviewing previous SLA…

This research creates an empirically derived, pedagogically useful list of formulaic sequences for academic speech and writing, comparable with the Academic Word List (Coxhead 2000), called the Academic Formulas List (AFL). The AFL includes formulaic sequences identified as (i) frequent recurrent patterns in corpora of written and spoken language,…

Two hypotheses were tested: Similarity between first language (L1) and second language (L2) orthographic processing facilitates L2-decoding efficiency; and L2-decoding efficiency contributes to word-meaning inference to different degrees among L2 learners with diverse L1 orthographic backgrounds. The participants were college-level English as a…

This longitudinal mixed-methods study compared the oral fluency of well-educated adult immigrants from Mandarin and Slavic language backgrounds (16 per group) enrolled in introductory English as a second language (ESL) classes. Speech samples were collected over a 2-year period, together with estimates of weekly English use. We also conducted…

Discusses prominent base units of discourse analysis designed for dealing with structural characteristics of second-language discourse, and offers arguments in favor of selecting the utterance as a valuable base unit. (95 references) (GLR)

Using methods from conversation analysis, this microethnographic longitudinal case study traces the development of interactional competence which results from adult learners' socialization into literacy events in a modified Sustained Silent Reading (mSSR) program. The investigation focuses on two learners who participated in the mSSR program in an…

Alternative assessment procedures have made consistent inroads into second and foreign language assessment practices over the last decade. The original impetus for alternative assessment methods has been predicated more on the ideological appeal this approach offers than on firm empirical evidence that alternative assessment approaches actually…

Discusses problems involved in scientific explanation in general and their relevance to theories of second-language acquisition (SLA) in particular. The property theory/transition theory distinction and the deductive-nomological model are examined. The use of Lipton's (1991) "best explanation" concept in evaluating SLA theoretical frameworks is…

This paper is a response to Paul Meara's (2005) critique of the Lexical Frequency Profile (LFP). Using simulated data, he challenges the claim that LFP is a sensitive and reliable tool for assessing vocabulary use in L2 speakers. In my response to his paper, I discuss the nature of lexical competence, in light of which LFP results should be…
