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 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…

In this narrative article, I document my implementation of action logs as a tool for reflective practice and teacher development as I transitioned from working in a small "eikaiwa" (English conversation) school to working in a private international university. After providing a brief description of my contextual background and how I came…

This article focuses on the design of digital instructional game (DIG) tasks for young second language (L2) learners. The aim of the study is to identify motivational task elements based on what children respond to positively in games and incorporate into their own L2 vocabulary learning game designs. Eighty-two sixth-grade students (ages 11-12…

This study examined how secondary teachers (junior and senior high school teachers) of English as a foreign language (EFL) in Japan participated in collaborative action research and engaged in their professional development over four years. In particular, little is known as to how EFL teachers challenge their beliefs and implement innovative…

Prior research showed that interleaved practice (studying multiple skills at once) is more effective than blocked practice (studying only one skill at a time). This study aims to replicate the benefits of interleaved practice on the proceduralization of second language (L2) syntax and further examines the role of working memory (WM) in different…

The present study investigated the effects of two types of core-image-based basic verb learning approaches: the learner-centered and the teacher-centered approaches. The learner-centered approach was an activity in which participants found semantic relationships among several definitions of each basic target verb through a picture-elucidated card…

The current project longitudinally investigated the extent to which first-year Japanese university students developed their second language (L2) oral ability in relation to increased input in foreign language classrooms. Their spontaneous speech was elicited at the beginning, middle and end of one academic year, and then judged by linguistically…

Feedback, or information given to learners regarding their performance, is found to facilitate second language (L2) learning. Research also suggests that the timing of feedback (whether it is provided immediately or after a delay) may affect learning. The purpose of the present study was to identify the optimal feedback timing for L2 vocabulary…

It has been repeatedly argued among vocabulary researchers that semantically related words should not be taught simultaneously because they can interfere with each other. However, the question of what types of relatedness cause interference has rarely been examined carefully. In addition, there are disagreements among the past studies that have…

This study investigates the effects of cognacy on vocabulary learning. The research expands on earlier designs by measuring learning of English-Japanese cognates with both decontextualized and contextualized tests, scoring responses at two levels of sensitivity, and examining learning in a more ecologically valid setting. The results indicated…

This study examined the effectiveness of explicit instruction of vocabulary learning strategies (VLSs) over a 10-week semester with a group of 146 female EFL learners from two Japanese universities. A vocabulary test and questionnaires on VLSs and motivation were administered at the beginning of the course. The learners were divided into two…

Interview guides and a questionnaire were developed in order to find what factors demotivated students in Japanese high school English classrooms. Five college students who were attending two private universities and one public university shared their views about demotivation in the interviews. Forty-two students at a public university responded…

Previous research investigating the effects of contextualized and decontextualized tasks on vocabulary learning has focused on whether or not learners were able to gain knowledge of meaning and form. To date, research has generated little evidence indicating that context facilitates vocabulary learning. Decontextualized tasks tend to be equally or…

This quasi-experimental study investigated the effectiveness of two types of vocabulary instruction--image-schema-based instruction (ISBI) and translation-based instruction (TBI)--on the acquisition of second language (L2) polysemous words. Fifty-eight Japanese high school learners of English were divided into two treatment groups (ISBI and TBI)…
