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…

Background: Vocabulary knowledge (VK) and morphological awareness (MA) are crucial linguistic variables for reading comprehension. However, the extent to which MA subskills are intertwined with different facets of VK in their contributions to reading comprehensions, and how MA influences the reading abilities of English as a foreign language (EFL)…

The current study investigated 29 first-year Japanese university students' usage of an online vocabulary notebook that automatically searched eight different word and phrase lists to provide students with reference information about their self-selected vocabulary. Over the course of a 14-week period, participants read English books and articles…

This study revisits the roles of different aspects of phonological vocabulary knowledge in second language (L2) listening. Japanese learners of English (n = 114) completed the TOEIC Listening test and three phonological vocabulary tests assessing (a) ability to recognize the meanings of aural forms (meaning recognition), (b) ability to recall the…

This study investigated the effects of two types of classroom instructions on EFL learners' oral proficiency by implementing teachers' judgment. Two intact classes of EFL university students studied a compulsory subject of their department under two different types of classroom instruction. The first group of students was trained with explicit…

This research sought to investigate EFL nursing students' use of vocabulary learning strategies to learn medical terminology and further assess strategies used in relation to learning outcomes measured by two types of vocabulary knowledge: meaning recall (passive recall) and meaning recognition (passive recognition). The participants, 138 EFL…

While writing has evolved away from the conventional method of using pens and paper in favor of digital tools (Li et al., 2019), English teachers continue to face difficulties in teaching writing. This study shows how mind-mapping and the program, Writeabout, can be merged for online writing classes in English for Specific Purposes (ESP)…

The type of processing-resource allocation (TOPRA) model predicts that the semantic processing of new second language (L2) words can impede the learning of their forms while structural processing can promote it. Using this framework, the present study examined the effects of processing type (semantic, structural, control), exposure frequency (one…

The purpose of this paper is to (a) establish whether meaning recall and meaning recognition item formats test psychometrically distinct constructs of vocabulary knowledge which measure separate skills, and, if so, (b) determine whether each construct possesses unique properties predictive of L2 reading proficiency. Factor analyses and…

This study compared the multidimensional effects of written and oral vocabulary exercises on EFL learners' retention of single-word items (SWI) and multi-word items (MWI). Two teaching experiments (times) were conducted with 54 college students, who studied four themed-based texts, two at a time. A total of 60 unfamiliar vocabulary items, 30 in…

The present study aims to examine how listening comprehension processes (top-down and bottom-up) differ by second language proficiency. To investigate such differences, experiments (listening tasks) followed by questionnaires and semi-structured interviews were conducted. Participants included 18 lower intermediate learners, 19 upper intermediate…

Language learners are underserved if there are unlearned meanings of a word that they think they have already learned. For example, "circle" as a noun is well known, whereas its use as a verb is not. For artificial-intelligence-based support systems for learning vocabulary, assessing each learner's knowledge of such atypical but common…

This study examined the impact of the manipulated task complexity (Robinson 2001a, 2001b, 2007, 2011; Robinson & Gilabert, 2007) on second language (L2) speech comprehensibility. I examined whether manipulated task complexity (a) impacts L2 speech comprehensibility, (b) aligns with L2 speakers' perception of task difficulty (cognitive…

The road to second language competence is a long and arduous one, and much of its effort involves learning to recognize and use vocabulary. Fortunately, anytime-anywhere learning with smart phones and smart apps offer a means to lessen the burden and make vocabulary learning more efficient. Accordingly, this study investigated 134 students across…

In recent years, there has been increasing debate and research regarding which modality of vocabulary knowledge has the strongest correlation to reading, with particular focus on distinctions between testing L2 form and L2 meaning, and between recall of answers from memory and recognition of answers from fixed options. However, relatively little…
