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…

Vocabulary knowledge is of paramount importance when learning a second language. It requires effective and practical classroom vocabulary learning methods for long-term acquisition. Specific learning aspects helping the learner remember vocabulary such as spaced repetition and retrieval practice have shown efficacy but are often disconnected from…

Gamification in second language acquisition research is a popular topic, but there are few empirical comparative studies in the literature. This quasi-experimental mixed-approach study enrolled 77 Japanese university EFL learners to enable a comparison between two digital vocabulary flashcard learning software conditions carefully designed by the…

Extensive Reading (ER) emerges as a promising approach for acquiring a foreign language, allowing for a large amount of language exposure. However, the influence of supplementary activities within ER programs has yet to be thoroughly investigated, despite previous studies suggesting their potential effectiveness. This research investigated the…

Research has shown that learning a known-and-unknown word combination leads to greater learning than learning an unknown word alone (Kasahara, 2010, 2011). These studies found that attaching a known adjective to an unknown noun can help learners remember the unknown noun. Kasahara (2015) found that a known verb can serve as an effective cue to…

The current study examined the extent to which first language (L1) utterance fluency measures can predict second language (L2) fluency and how L2 proficiency moderates the relationship between L1 and L2 fluency. A total of 104 Japanese-speaking learners of English completed different argumentative speech tasks in their L1 and L2. Their speaking…

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…

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…

The present study investigates the use of generative strategies and their effect on second language (L2) vocabulary retention and learner confidence in vocabulary knowledge over time. Generative strategies (or generation) are one in a group of learning methods known as desirable difficulties -- strategies that improve long-term learning by adding…

This longitudinal study investigated development of second language (L2) reading comprehension ability and predictive contributions of five L2 reading components (word recognition speed, listening comprehension, vocabulary breadth, grammar knowledge and first language [L1] reading comprehension) using latent growth curve modelling. The…

While previous research has provided insights into vocabulary learning through extensive reading, the differential effects of word frequency and word class on active form and passive meaning word recognition remain less understood. By evaluating learners' post-test performance in active form recognition and passive meaning recognition, this study…

The purpose of this study is to determine whether a vocabulary size test is a valid and reliable measure of longitudinal growth in vocabulary size (VS), and to investigate the relationship between growth in VS and use of vocabulary learning strategies (VLS). Kasahara's (2006) revised version of Mochizuki's (1998) Vocabulary Size Test (VST) was…

Research suggests that second language (L2) readers often lack strategic competence in dealing with unknown lexica. This mixed methods study of Japanese readers of English used eye tracking and other methods to empirically examine the use and efficacy of vocabulary coping strategies, including dictionary use, inferring meaning from context, and…

This article presents a work-in-progress focused on developing an experiment to investigate the effectiveness of different types of deliberate paired-associate computer-assisted language learning (CALL). First, the rationale for Japanese EFL learners' current need for doubling their efforts with this technique is explained. Next, an overview of…

This exploratory study represents an attempt to investigate the factors that may affect the reading comprehension abilities of English as an additional language (EAL) learners. For this study, we examined a participant group of 31 (25 EAL and 6 first language English) learners studying at an international school in Japan. We assessed the…
