Vocabulary knowledge plays an important role in language learning and language proficiency, but it is difficult to know how much of a role it plays without appropriate vocabulary measures. In this article, we first discuss learner vocabulary in our research on Korean as a second/foreign language. Unable to find appropriate measures for receptive…

This paper represents a summary and discussion of the three studies presented at the morning session of the Fall 2022 JALT Vocabulary SIG. The papers, which were written by Ali Al-Hoorie, Masaki Eguchi, Derek Canning, Stuart McLean, Christopher Nicklin, and Joseph Vitta, represent a range of topics and study designs that are common in recent…

Despite the substantial expansion in vocabulary research since the 1980s, we still know very little about how vocabulary develops over time and what factors influence this development. This methodological overview discusses key issues and considerations in vocabulary breadth growth assessment to help advance research in this area. The report…

Local item dependency (LID) occurs when test-takers' responses to one test item are affected by their responses to another. It can be problematic if it causes inflated reliability estimates or distorted person and item measures. The cued-recall reading comprehension test in Hu and Nation's (2000) well-known and influential coverage--comprehension…

The Vocabulary Size Test (VST) measures English learners' decontextualised receptive vocabulary knowledge of written English and has nine bilingual versions with multiple-choice options written in other languages. This study used the English-Japanese version of the VST to investigate the extent to which loanword items were answered correctly by…

The present study investigates the use of generative strategies and their effect on second language (L2) vocabulary retention and learner confidence in vocabulary knowledge over time. Generative strategies (or generation) are one in a group of learning methods known as desirable difficulties -- strategies that improve long-term learning by adding…

In an upcoming coverage-comprehension study, we plan to assess learners' meaning-recall knowledge of words as they occur in the study's reading passage. As several meaning-recall test formats exist, the purpose of this small-scale study (N = 10) was to determine which of three formats was most similar to a criterion interview regarding mean score…

In recent years, there has been increasing debate and research regarding which modality of vocabulary knowledge has the strongest correlation to reading, with particular focus on distinctions between testing L2 form and L2 meaning, and between recall of answers from memory and recognition of answers from fixed options. However, relatively little…

As vocabulary plays an important part in L2 learning at the beginner level, investigation into vocabulary learning constitutes an essential part of second language acquisition research (Koda, 1989; Laufer, 1992; Meara, 1992). Assuming the case of Japanese, English education can provide a meaningful example. In addition, noting that precise…

Semantic variables enable L2 researchers and materials creators to quantify and control the effects of meaning on cognition. However, in recent years, many variables have been normed and published. Parsing the methods employed in norming this myriad of variables and which disparate theories informed their creation can be an opaque and arduous…

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…

Laufer (1988) introduced the concept of synform errors, where second language (L2) learners confuse a word for a different but similar looking or sounding L2 word. Stubbe and Cochrane (2016) reported that of 1,187 commonly repeated errors on a Japanese to English non-contextual translation test, 461 were synform errors (39%). This study introduces…

A fundamental skill required for vocabulary development is word recognition ability. According to Perfetti (1985), word recognition ability relies on low-level cognitive processing skill to be automatic and efficient in order for cognitive resources to be allocated to high-level processes such as inferencing and schemata activation needed for…

The purposes of this study were to: (1) build an appropriate model for predicting primary schoolchildren's English vocabulary knowledge; (2) examine whether the developed model applies to new data; and (3) discuss how to apply the model to L2 vocabulary instruction. More specifically, the study asked third- and fourth-grade public primary school…

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…
