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…

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…

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),…

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 study reports the perceptions and understanding of extensive reading (ER) of 259 ER practitioners in Japan, Thailand, Mongolia, and Vietnam. The majority of participants understood the core principles of ER, namely (a) the fluent reading of (b) a lot of (c) easy texts. However, about 25% of the participants in Thailand, Mongolia, and Vietnam…

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…

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…

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…

In this article, Charlie Taylor offers a commentary on Yang et al.'s 2021 "Reading in a Foreign Language" article, "Text Difficulty in Extensive Reading: Reading Comprehension and Reading Motivation." In their study, Yang et al. analyzed the effects of text difficulty on the reading comprehension and motivation of high school…

This study investigates the effects of the text difficulty of extensive reading materials on the reading comprehension and reading motivation of English as a foreign language (EFL) vocational high school students in Taiwan. Two experimental groups were assigned, on an individual basis, to read graded readers at either one level below ('i-1') or…
