This study investigated the role of parental support and selected family variables in the first (L1) and second language (L2) vocabulary development of Japanese heritage language (JHL) high school students in the United States. Eighty-two JHL students ages 15-18 from eight hoshuukoo (i.e., supplementary academic schools for Japanese-speaking…

This study explored the pedagogical benefits of flipped online kanji (i.e., Chinese characters used in Japanese) instruction integrated into college-level introductory and intermediate Japanese language courses. Using a quasi-experimental mixed design, the investigation looked at the effects of two instructional approaches: (1) a flip approach in…

Research into dual-modality theory has long rested on the assumption that presenting input in two modalities leads to better learning outcomes. However, this may not always hold true. This study explored the possible advantages of using dual modality in repeated reading--a pedagogy often used to enhance reading development--for two literacy…

This study investigates the role of motivation and learner variables in bilingual vocabulary development among first language (L1) Japanese students attending hoshuukoo (i.e., supplementary academic schools for Japanese-speaking children) in the United States. One hundred sixteen high school students ages 15-18 from eight hoshuukoo completed…

This study examines bilingual vocabulary knowledge in relation to arrival age among first language (L1) Japanese students attending "hoshuukoo" (i.e., supplementary academic schools for Japanese-speaking children) in the United States. It also examines the relationship between L1 Japanese and English as a second language (L2), as…

This study investigates whether "socialness" increases the memorability of newly acquired knowledge of a second language (L2). Three groups of beginning learners of Japanese learned 10 novel Japanese words through a Q & A session. Group 1 did the session with a human interactant and learned the novel words from him. Group 2 did the session alone…

Presents a case study of vocabulary learning in Japanese for five students under different instructional conditions. Examines whether output activities facilitated the retention of words more effectively than input-dominant activities, which require students to comprehend questions involving target words but do not encourage them to use the words…

Examination of the effects of transferred vocabulary knowledge on college students' (N=24) acquisition of Japanese linguistic knowledge, verbal processing skills, and reading comprehension indicated that vocabulary knowledge was most highly correlated with reading comprehension. This initial advantage magnified its effects over time as task…
