We investigated whether learning and retaining vocabulary in a second language (L2) can be improved by leveraging a combination of memory enhancement techniques. Specifically, we tested whether combining retrieval practice, spacing, and related manipulations in a 'multidomain' pedagogical approach enhances vocabulary acquisition as compared to a…

This article explores how leading textbook authors select and instruct vocabulary in beginner and intermediate Chinese textbooks used in the United States. Leading textbook authors were approached; subsequently; four authors completed interviews with pre-designed questions. Grounded theory methodology was used to analyse the interviews, and their…

Research has shown that learning a known-and-unknown word combination leads to greater learning than learning an unknown word alone (Kasahara, 2010, 2011). These studies found that attaching a known adjective to an unknown noun can help learners remember the unknown noun. Kasahara (2015) found that a known verb can serve as an effective cue to…

This study investigates the effect of personal investment in the form of learner-generated content (LGC) on the lexical recall of beginning-level learners of Chinese. The study employed a 2 x 2 repeated-measures design with content at two levels -- teacher-generated content or TGC, and learner-generated content or LGC -- and time at two levels…

Learners entering higher education may learn specialized vocabulary of new disciplines in their second language (L2) with or without support from their first language (L1). However, these learners cannot rely on an established conceptual representation in L1 when learning L2 specialized vocabulary. The effects of learning a new concept in L1 prior…

It has been repeatedly argued among vocabulary researchers that semantically related words should not be taught simultaneously because they can interfere with each other. However, the question of what types of relatedness cause interference has rarely been examined carefully. In addition, there are disagreements among the past studies that have…

This study investigated (1) the extent of vocabulary learning through reading and listening to 10 graded readers, and (2) the relationship between vocabulary gain and the frequency and distribution of occurrence of 100 target words in the graded readers. The experimental design expanded on earlier studies that have typically examined incidental…

This study investigates whether congruency (+/- literal translation equivalent), collocate-node relationship (adjective-noun, verb-noun, phrasal-verb-noun collocations), and word length influence the learning burden of EFL learners' learning collocations at the initial stage of form-meaning mapping. Eighteen collocations were selected on the basis…

This article overviews current research on second language vocabulary learning. It concludes that a large vocabulary is necessary to function in English: 8000-9000 word families for reading, and perhaps as many as 5000-7000 families for oral discourse. In addition, a number of word knowledge aspects need to be learned about each lexical item.…
