Languaging--that is, using language to mediate thinking, orally or in writing--facilitates second language (L2) learning. As languaging requires the deliberate, analytical action of L2 learners, learners with higher language aptitude are likely to benefit more from languaging than those with lower aptitude. Thus, this study investigated the extent…

This study examined the relationship between lexical coverage (i.e., the percentage of known word tokens in a text) and second language (L2) reading comprehension. Several studies have suggested that adequate comprehension occurs between 95% and 98% coverage, but no study has investigated beginning-level learners reading under the conditions of…

This study investigated incidental learning of single-word items and collocations through listening to teacher talk. Although there are several studies that have investigated incidental vocabulary learning through listening, no intervention studies have explicitly investigated the extent to which listening to teachers in a classroom context might…

This study examined the contributions of morphological awareness (MA) to second language (L2) word meaning inferencing in English-speaking adult learners of Chinese (N = 50). Three research questions were posed: Are L2 learners sensitive to the morphological structure of unknown multi-character words? Does first language (L1) MA contribute to L2…

This study launched an investigation into the extent to which textual enhancement in captions can promote learner attention to and subsequent development in second language (L2) grammar. Using eye-tracking, it also intended to extend research on the relationship between attention and L2 learning. A pretest-posttest experimental design was…

This study examined how well second language (L2) recall and recognition vocabulary tests correlated with a reading test, how well each vocabulary test discriminated between reading proficiency levels, and how accurate each test was in predicting reading proficiency when compared with corpus studies. A total of 116 college-level learners of…

This study investigated the relationship between vocabulary learning strategies and vocabulary breadth and depth knowledge. One hundred and fifty first-year university students in China took the Vocabulary Levels Test, a meaning recall task, and the Depth of Vocabulary Knowledge Test. The first two tests were used to elicit two types of vocabulary…

Elicited imitation requires listeners to listen and repeat sentences as accurately as possible. In second language acquisition (SLA) research it has been used for a variety of purposes. Recently, versions of the same elicited imitation test (EIT) have been created in 6 languages with the purpose of measuring second language proficiency (Ortega…

This study investigated whether second language (L2) speakers' morphosyntactic pattern learning was predicted by their statistical learning and working memory abilities. Across three experiments, Thai English as a Foreign Language (EFL) university students (N = 140) were exposed to either the transitive construction in Esperanto (e.g., "tauro…

One of the central considerations in the validity argument for the TOEFL iBT is the relationship between the language on the exam and the language required for university courses. Corpus linguistics has recently been shown to be an effective way to explore this relationship, which can also be considered as an aspect of authenticity. Applying…

Examining speech samples from 75 American university students learning 1 of 3 languages (Mandarin, Russian, and Spanish), this article reports on a study of second language (L2) learners' oral fluency development and its relationship with their gains in holistic proficiency ratings during a semester abroad. In study abroad research, there is a…

This study investigates relations between second language (L2) lexical input and output in terms of word information properties (i.e., lexical salience; Ellis, 2006a). The data for this study come from a longitudinal corpus of naturalistic spoken data between L2 learners and first language (L1) interlocutors collected over a year's time. The…

This cross-sectional study used assessments developed by the Center for Applied Linguistics to examine the oral proficiency of 218 K-8 English-proficient students in 4 Spanish immersion programs. Following a comprehensive review of assessment results for English-proficient immersion learners, the article reports findings from statistical analyses.…

The current study investigated task effects on listener perception of second language (L2) comprehensibility (ease of understanding). Sixty university-level adult speakers of English from 4 first language (L1) backgrounds (Chinese, Romance, Hindi, Farsi), with 15 speakers per group, were recorded performing 2 tasks (IELTS long-turn speaking task…

This study suggests that Intermediate High and Advanced speakers produce aspectually valid constructions in Oral Proficiency Interviews (OPIs) in large part because they are doing more than assigning aspect to lexical categories (Lexical aspect hypothesis), but because they are assigning lexicalized meaning to discrete verbs, for example…
