This study investigated the relative contributions of English morphological and vocabulary knowledge to second language (L2) reading comprehension among 100 adult Japanese English as a foreign language (EFL) learners. The study also investigated the extent to which the roles of morphological and vocabulary knowledge in L2 reading comprehension…

Graded readers are a great asset to learners acquiring the vocabulary of another language. Homonyms, on the other hand, are a recognized source of trouble for students with that same goal. Publishers of graded readers control the presentation of old and new words, but does this control extend to homonyms? Are only the word forms controlled for--in…

This study examines how the perceptions that twelve teachers of Japanese as a second language (L2) had of extensive reading (ER) changed following 10 months of online English ER. Interviews provided much of the study data, supported by pre-project and post-project questionnaires. The participants' pre-project and post-project vocabulary sizes and…

We are encouraged by Cobb's (2022) description of changes to the Morpholex profiling tool (https://www.lextutor.ca/cgi-bin/morpho/lex/) resulting in more accurate word classifications. This addresses one point in our recent commentary on Morpholex and on Laufer and Cobb's (2020) study using Morpholex (McLean & Stoeckel, 2021). However, Cobb…

Using a mixed method explanatory sequential design, this study investigates intensive English program (IEP) instructors' perceptions of the impact of COVID-19 emergency remote teaching on reading instruction. Forty-four IEP instructors completed an online survey, and seven of them participated in follow-up interviews. Both quantitative and…

In the late 1980s Batia Laufer worked with teachers who believed that to understand a text it was enough to understand 80% of the text's word tokens. In response, Laufer set out to calculate the minimal text coverage, i.e., percentage of running words in a text the reader should understand to comprehend it reasonably well. In 1992, she explored…

In response to McLean (2021), Laufer (2021) makes three claims which are either not supported by research or are based on studies with important limitations. First is that a vocabulary size, instead of a level, can be used to match learners with lexically appropriate materials despite test creators and research not supporting this. Second is that…

This study explored the lexical coverage of corpus-based vocabulary lists (general, academic, and content-specific) across several million tokens gathered from digital science resources (DSR) for middle school (6-8 grade) students in the United States. The goal was to estimate the extent to which a combination of well-known word lists, mostly…

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…

Studies of lexical coverage are valuable because they reveal the importance of vocabulary knowledge to comprehension. Lexical profiling research is also extremely useful because it indicates the vocabulary knowledge necessary to understand different text types such as novels, newspapers, academic lectures, television programs, and movies.…

The study investigated the effect of marginal glossing and frequency of occurrence on the incidental learning of six aspects of vocabulary knowledge through reading in the second language (L2) Chinese. Participants were 30 intermediate L2 Chinese learners in an American public university. The MACOVA tests indicated that the treatment group who…

This study explored the contribution of second language (L2) discipline-specific vocabulary to Chinese chemistry major undergraduates' reading of textbooks. Participants included 82 second-year undergraduates majoring in chemistry. Their discipline-specific vocabulary knowledge and chemistry textbook reading ability were measured. Their L2…

Despite empirical evidence from research showing that the use of text-picture combination is beneficial for second language (L2) learning, little is known about the effectiveness of reading comic books for incidental vocabulary acquisition. This study investigated the effects of engaging with comic books on incidental learning of L2 Italian…

This mixed-methods case study examines how an online extensive reading project impacted the 11 participants' motivation, habits, and linguistic abilities regarding L2 English reading. The participants engaged in extensive reading for one year on Xreading (an online extensive reading website). They were all female Japanese nationals aged between 30…

Second language (L2) learners comprehend more when they are prepared for novel vocabulary that they encounter in a text. Input-based incremental (IBI) vocabulary instruction (Barcroft, 2012) provides L2 instructors and learners with a means of achieving this goal by (a) presenting optimal input to learners at the right time during a…
