This study examined the trajectories of the multi-word constructions (MWCs) in 98 advanced second language (L2) learners during their first-year at an English-medium university in a non-English-speaking country, using linear mixed-effects modelling, over one academic year. In addition, this study traced the academic reading input that L2 learners…

In successful writing development, English as a foreign language (EFL) learners not only need to acquire grammatical complexity (GC) features but also know when and how to use them flexibly across communicative contexts, known as register flexibility. The present study, guided by the sociocultural theory of language learning, examines descriptive…

Language borrowing from sources is a phenomenon used by developing writers as they are learning academic language, though there is much to be learned about how younger students borrow from sources. This study explores student writing, from a sample of 166 diverse middle graders, across topics to determine patterns in borrowing from instructional…

The aims of the current project were to: (1) describe average change in the use of academic words across the school year in writing and (2) examine potential predictors of growth in academic word use in response to morphology-focused supplemental instruction. Investigators utilized written expository responses of 824 students in 5th grade before…

This study investigates the concurrent and longitudinal relationships between polysemous word knowledge and reading comprehension among bilingual students (n = 107) followed from seventh to eighth grade. Standardized tests were used to measure decoding skills, broad vocabulary knowledge, and reading comprehension. Data about students' polysemous…

This study examined how students of English as a foreign language (EFL) with different first language (L1) backgrounds use interactional metadiscourse markers in argumentative writing. Specifically, to explore unique patterns of metadiscourse features that reflect context and development, the essays written by Chinese, Japanese, and Korean EFL…
