In second language (L2) research, the lexical unit is often defined as a base word plus inflectional and derivational forms through Level 6 of Bauer and Nation's framework (WF6). WF6 use has been justified by the assumption that once a form is known, recognition of other WF6 members requires little extra effort. A more lenient view holds that an…

To date, attempts at empirically validating a construct of academic vocabulary in the form of a frequency list in languages other than English remain conspicuously absent in peer-reviewed journals. This study aims to close this gap by using Russian as a case study to develop an academic vocabulary list and prove its viability through a variety of…

This study explores the lexical profile of essays written by 48 advanced learners of second language (L2) Russian who participated in the Russian Overseas Flagship, an intensive year-long study abroad program designed to help students reach Interagency Language Roundtable (ILR) Level 3 proficiency in all skills. Using the lexical frequency profile…

The awarding organizations that create and administer high-stakes assessments for beginner-to-low-intermediate 16-year-old learners of French, German, and Spanish in England provide optional topic-driven word lists as guides for teachers and textbook writers. Given that these lists are developed by the awarding organizations, they exert a powerful…

Linguistic complexity serves as an important measure of second language (L2) writing development. Complexity indices, however, rarely feature in the studies of learner languages other than English. Additionally, L2 writing studies have been criticized for the lack of consistency in defining proficiency. The current study addresses these gaps by…

This study examined how mode of input affects the learning of pronunciation and form-meaning connection of second language (L2) words. Seventy-five Japanese learners of English were randomly assigned to 1 of 3 conditions (reading while listening, reading only, listening only), studied 40 low-frequency words while viewing their corresponding…

Two studies examined the role of input distribution in English construction learning, by child learners from a Mandarin first-language background, and the extent to which phonological short-term memory and awareness predicted such learning. In the first study, 4th-grade students of Mandarin Chinese (N = 121) learned the English object-cleft…

This study examined the effectiveness of Zipfian frequency at facilitating the acquisition of English prenominal past participles. Chinese middle school students (N = 103) were randomly assigned to a sequenced Zipfian frequency (SZF) group, a random Zipfian frequency (RZF) group, a balanced frequency (BF) group, and a control group. A mixed…

The aspect hypothesis (Andersen & Shirai, 1994) proposes that language learners are initially influenced by the inherent semantic aspect in the acquisition of tense and aspect (TA) morphology. Perfective past emerges earlier with accomplishments and achievements and progressive with activities. Although this hypothesis has been extensively…

Examined the development of the word knowledge of two groups of advanced learners of French as a second language by means of a slightly revised version of a particular test format. Studied the type of distractor most suited to the participants, distinguished the role of three types of associations, and linked qualitative aspects of word knowledge…

A review of the difficulties Spanish-Americans and Mexican-Americans encounter in learning English, caused by a lack of knowledge of common idioms and figures of speech in current usage, leads to a discussion of two pilot studies in which the frequency of occurrence of idiomatic and figurative constructions in the reading materials presented to…
