There are few published estimates of vocabulary sizes amongst students in tertiary education. Research does not offer estimates of the vocabulary size tertiary students might be expected to possess, though estimates exist for K-12 education, some EFL contexts, and the general population. Such research is important. For reading comprehension during…

This study explored words in materials science research articles using New Academic Word List (NAWL) and New General Service List (NGSL) created by Browne at al. (2013) as reference lists. The objectives of this research were to explore the frequency and coverage of the NAWL and the NGSL in materials science research articles and identify…

In this commentary, we begin with the discussion on a brief history of academic wordlists. Adopting a comparative perspective, then, the merits and demerits of the Academic Word List (AWL) (Coxhead, 2000) and its competing counterpart the Academic Vocabulary List (AVL) (Gardner & Davies, 2014) are presented. We also explore whether the AWL can…

This true longitudinal study explored the lexical development of L2 university English major students in Thailand using two learner corpora. This study analyzed the natural learners' English language writing assignments from two writing courses and tracked their lexical development over a relatively long period (three years with five batches of…

When learning high- and mid-frequency words, approximately 5,000 words might be inadequate for learners to survive in a career as a tourist guide. This paper aims to construct technical word lists for Thai tourist guides to serve as supplementary learning materials. Different word lists need different criteria for their construction. Three main…

Research into vocabulary knowledge often differentiates between breadth (how many words a person knows) and depth (how well the words are known). Both theoretical categories are essential for understanding language learners' lexical development, but how the different aspects of vocabulary knowledge interconnect has not received the same attention…

Academic vocabulary networks were examined in 3 elementary grades textbook programs (first through fifth grade) in 3 domains--science, mathematics, and social studies. Within each program, a given network consisted of a focal domain-specific academic word and the collection of words from all grades that overlapped in meaning with the focal word.…

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…

Several researchers have claimed that low-achieving students, especially second language students, need explicit academic vocabulary instruction to "catch up" with their age peers (e.g., Nagy & Townsend, 2012). Two possible paths to vocabulary growth -- free reading and explicit vocabulary instruction -- were compared in terms of…

Since written assignments often constitute the main form of assessment in tertiary education, academic writing skills are of paramount importance to university students. The role of academic writing in turn emphasises two aspects vital for successful written production at universities: genre awareness as students are assessed on the production of…

Some researchers have argued that low-achieving students may never acquire sufficient levels of academic vocabulary to be successful in school without some form of explicit vocabulary instruction (e.g. Snow, Lawrence, & White, 2009). In this paper, I summarize the available data on the efficiency, in words learned per minute of instruction, of…

The availability of corpora has greatly strengthened the possibilities of identifying high-frequency lexical items in a more systematic and objective manner than has typically been used for vocabulary instruction. This article adopts a corpus-based approach to accommodate the vocabulary instructional needs of students enrolled in university…

This study explored the effects of three types of lexical tools (MOOCs, E-dictionaries, and lexical concordancers) and three types of lexical applications (technology-mediated communication-based applications (TMCA), Anki as an e-flashcard application, and WordUp as a dedicated lexical application) on learning academic core words among a sample of…

The current corpus-based study investigated the lexical profile of psychology research articles based on General Service List (GSL) (West, 1953) and Academic Word List (AWL) (Coxhead, 2000). To this end, a corpus of 8,500 psychology research articles with around 74 million words was analyzed. The results showed that the AWL accounted for 13.12% of…

Individuals with lower proficiency in a second language tend to produce more disfluent speech patterns in the second language. Speech disfluencies refer to interruptions in the forward flow of speech and are distinct from the colloquial use of "fluency," to characterize knowledge of a language. Prior research indicates that some speech…
