Extensive reading (ER) has been found to have an assortment of positive effects on various aspects of second/foreign language learning. However, few studies have investigated its impacts on learners of Chinese as a Foreign Language (CFL), especially early beginning learners. To address this gap, this study reports an intervention of extensive…

Morphological knowledge is a complex construct integral to vocabulary breadth and reading comprehension. To understand its complexity, researchers examine its dimensionality. First, this study contributes to this broad topic by investigating whether morphological awareness and affix knowledge, related concepts with a long history of investigation…

The current study investigates whether vocabulary breadth, vocabulary depth, and vocabulary fluency contribute differentially to L2 reading and listening comprehension. One hundred and thirty-eight EFL learners first took three vocabulary knowledge tests that measured vocabulary fluency, vocabulary breadth, and vocabulary depth. Subsequently, they…

Ensuring classroom reading materials align with learners' lexical knowledge is crucial, often requiring teachers to infer vocabulary knowledge from vocabulary test performance. However, the best approach to match learners with lexically appropriate texts based on vocabulary test scores remains unclear. This study compared two methods:…

Few studies aimed to disentangle different aspects of vocabulary depth (VD) knowledge and examine their contribution to second-language (L2) reading comprehension. To fill this gap, this study distinguished between two VD aspects, that is, semantic network knowledge and polysemous knowledge; and tested how they, together with vocabulary size (VS),…

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…

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…

Metacognitive knowledge is essential to vocabulary learning and reading. However, there have been few longitudinal studies investigating how the breadth of vocabulary knowledge mediates the relationship between metacognitive knowledge and reading over time in a foreign language context. This study involved 361 primary school students, who were…

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…

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…

This bibliometric study analyzed the research topic structure of the "Reading in a Foreign Language" ("RFL") journal in the past two decades. Using two well recognized bibliometric approaches, namely, the keyword co-occurrence analysis and hierarchical cluster analysis, the study examined author keywords and their co-occurrence…

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…

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…

The incidental or implicit learning of vocabulary has long been a topic of interest in various disciplines. In studies on foreign language acquisition, reading is often the activity that researchers use to generate their findings. "Reading in a Foreign Language" has maintained its position at the forefront of this research, consistently…

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…
