Knowledge of derivational affixes makes an important contribution to second language learners' success when reading. Yet while the effects of some learner variables (L2 proficiency, L1 background) have been investigated, there has been little research addressing the effects of varying characteristics of affixes on their acquisition. The goal of…

The New General Service List (NGSL; Browne, Culligan, & Phillips, 2013b) was published on an interim basis in 2013 as a modern replacement for West's (1953) original General Service List (GSL). This study compared GSL and NGSL coverage of a 6-year, 114-million word section of the Corpus of Contemporary American English (COCA), and used COCA…

Vocabulary learning is unarguably one of the sub-goals in every language classroom. The learning and teaching of vocabulary have been transformed by the development of general word lists, providing compilations of the most prevalent vocabulary items used in everyday contexts. These lists have made an invaluable contribution to the field of applied…

Japanese loanwords are mainly derived from English. These loanwords provide a considerable first-language (L1) resource that may assist in second-language (L2) vocabulary learning and instruction. However, given the huge number of loanwords, it is often difficult to determine whether an English word has a loanword equivalent and whether the…

VocQGen is an automated tool designed to generate multiple-choice cloze (MCC) questions for vocabulary assessment in second language learning contexts. It leverages several natural language processing (NLP) tools and OpenAI's GPT-4 model to produce MCC items quickly from user-specified word lists. To evaluate its effectiveness, we used the first…

This study outlines the steps taken to create an academic multi-word unit list derived from corpus data. It gives details on the procedure used and the rationale behind why certain approaches were utilised. It also compares existing resources and makes some suggestions for practical use of the resulting resource.

The selection of an appropriate word counting unit (WCU) for the purpose of second/foreign language vocabulary acquisition (SLVA) in the last decade has become a very important and relevant topic in academic circles. However, few studies address on-the-ground teaching practices and perspectives. This mixed-approach study, conducted through an…

The choice of word counting units (i.e. word family, flemma, or lemma) is of great importance in vocabulary list and test creation, as there are assumptions underpinning the use of each. Flemma-based counting assumes that if a learner can understand the meaning of a word in one part of speech (POS), they can also understand its meaning when the…

This study examines the application of an IRT analysis of words on lists including the General Service List (GSL), New General Service List (NGSL), Academic Word List (AWL), New Academic Word List (NAWL), and TOEIC Service List (TSL). By comparing line graphs, density distribution graphs, and boxplots for the average difficulty of each word list…

This article examines how English as a foreign language learners might be better matched to reading texts using automatic readability analysis. Specifically, I examine how the lexical decoding component of readability might be validated. In Japan, readability has been mostly determined by publishers or by professional reading organizations who…

By comparing the vocabularies included in the Japan Association of College English Teachers (JACET) wordlists (1993, 2003, and 2016 editions) and recently released New General Service Lists (Brezina & Gablasova, 2013; Browne, 2013), we tried to identify the construct of "the vocabulary for Japanese learners" with which JACET…
