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…

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…

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 main goal of this research is to systemize, build, and test prototype software to demonstrate Indirect Spaced Repetition (ISR) as a viable concept for Second Language Vocabulary Acquisition (SLVA). ISR is designed around well-founded spaced repetition and SLVA principles. Most importantly, it is based on Nation's (2001) recommendation to…

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…

Mnemonic strategies are not often utilised by Japanese students to learn and consolidate vocabulary, despite research showing that they are particularly effective. As part of an informal action research process, a structured lesson plan was devised that would introduce mnemonic strategies indirectly, that is, not by applying them directly to…

This study investigated the recall of words learned through two deliberate learning techniques, word cards and list learning. While the literature points to word cards as being more effective, Japanese learners of English are seen to prefer list learning, which may indicate unique learning styles stemming from a non-alphabetic L1. To test the…

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…

This article introduces three important challenges and possible solutions when using spoken dialogue to measure the use of specific multiword expressions. The first challenge is deciding whether to count precise and accurate use of target expressions only or whether to extend the count to include variation. The second challenge requires addressing…
