The adjustment of syntactic and phraseological complexity is a key consideration in text adaptation. However, research on this topic in the context of Chinese as a second language (CSL) remains limited. Using 700 CSL reading texts graded following the newly issued Chinese Proficiency Grading Standards for International Chinese Language Education,…

This study aimed to examine incidental learning of multiword expressions (MWEs) from bilingual captioned videos among language minority students. The participants consisted of 403 language minority university students enrolled in the Preparatory Year Programme (PYP) in the Southern part of China. The study evaluated participants' vocabulary…

Narrow reading has the potential to reduce vocabulary load and to provide rich opportunities for developing collocation knowledge, but these benefits rely on narrow reading increasing lexical repetition within a text. Hence, interest in narrow reading has been limited by the relatively small lexical effect of narrowing reading by topic (Nation,…

We investigated whether the accuracy of grammatical morphemes in second language (L2) learners' writing is associated with usage-based distributional factors. Specifically, we examined whether the accuracy of L2 English inflectional morphemes is associated with the availability (i.e., token frequency) and contingency (i.e., token frequency…

One of the important components in second language (L2) development is to produce clause-level units of form-meaning pairings or argument structure constructions. Based on the usage-based constructionist approach that language development entails an ability to use more diverse, more complex, and less frequent constructions, this study tested…

This study investigates whether re-thinking the separation of lexis and grammar in language testing could lead to more valid inferences about proficiency across modes. As argued by Römer, typical scoring rubrics ignore important information about proficiency encoded at the lexis-grammar interface, in particular how the co-selection of lexical and…

Focus on form (FonF) studies have predominantly addressed its effectiveness in improving learners' syntactic, lexical, orthographic, and phonological knowledge. Extending the scope of this line of research to formulaic FonF practices, this study investigates the relative effectiveness of incidental FonF targeting formulaic versus nonformulaic…

This longitudinal study investigates the effect of mode of reading on the incidental learning of collocations and factors that affect learning. One hundred Vietnamese pre-intermediate learners of English as a foreign language (EFL) were assigned to either an experimental group or a control group (no treatment). In 9 weeks, the experimental group…

This dissertation explored whether unnecessary linguistic complexity (LC) in mathematics and biology assessment items changes the direction and significance of differential item functioning (DIF) between subgroups emergent bilinguals (EBs) and English proficient students (EPs). Due to inconsistencies in measuring LC in items, Study One adapted a…

Learner corpus studies using syntactic complexity as a construct for characterizing learner proficiency have found that higher proficiency permits learners to produce more complex syntactic structures. However, the majority of previous studies have focused on writing, almost exclusively with adult second language (L2) learners. Given the…

While fluency in second language speaking can be a challenging construct to measure, it is important to identify the discourse features that contribute to it. This small-scale classroom research project examined the effect of formulaic language sequences on fluency as measured by computer-based speaking tasks of young English learners. Thirty-six…

Languages differ in their preferences for particular intensifying constructions. While intensifying adjectival compounds (IACs) (e.g. "ijskoud, ice-cold") are productively used to express intensification in Dutch and English, in French this construction is hardly productive. Consequently, French-speaking learners may encounter…

The present study explores the incidental learning of formulaic sequences (FS) from audio-visual input and factors affecting the learning of FS. A pretest-posttest, within-participant design was adopted. English-as-a-foreign-language learners (L1 = Dutch; n = 42) watched a one-hour English-language documentary without subtitles. Learning gains…

Formulaic sequences comprise a large body of language and their mastery is supposed to be a key determiner of language proficiency. However, despite their significance in language learning, they are seldom taught in any principled manner in language classrooms and their correct and appropriate use remains a particular challenge to language…

This study investigated Vietnamese EFL learners' knowledge of verb-noun and adjective-noun collocations at the first three 1,000 word frequency levels, and the extent to which five factors (node word frequency, collocation frequency, mutual information score, congruency, and part of speech) predicted receptive knowledge of collocation. Knowledge…
