    Uchihara, T, Harada, T

    TESOL Quarterly   52 ( 3 ) 564 - 587  2018  [Refereed]

     View Summary

    This study investigated the relationship between vocabulary knowledge (written and aural receptive vocabulary size and self-rating of vocabulary knowledge) and self-perceptions of four language skills (reading, listening, writing, speaking) targeting undergraduate students in English-medium instruction (EMI) courses in Japan. The students' academic performance (course grades and quiz scores) was also compared to their vocabulary knowledge. Results showed that learners with larger aural vocabulary sizes were more confident in spoken language use, and those who self-rated higher on their vocabulary knowledge were more likely to perceive themselves as proficient in productive language skills. Interestingly, learners with larger written vocabulary sizes tended to perceive themselves as less proficient in performing EMI tasks. Results also showed that none of the vocabulary measures were significantly associated with academic outcomes. Interview data suggest that EMI students' performance could be affected by the complex interplay of various factors, though not necessarily a large vocabulary size alone. Based on these findings, implications are discussed in terms of teaching and assessing vocabulary knowledge in EMI courses.

  • The production of voice onset time (VOT) by English-speaking children in a Japanese immersion program

    IRAL - International Review of Applied Linguistics in Language Teaching   45 ( 4 ) 353 - 378  2007.12  [Refereed]

    Authorship:Lead author

     View Summary

    This study analyzed the production of voice onset time (VOT) for /p, t, k/ in Japanese and English by English-speaking children (n 15) in a Japanese immersion program. The immersion children produced Japanese voiceless stops with significantly longer VOT values than the monolingual Japanese children and the immersion teachers, but they produced them with significantly shorter VOT values than their English VOT. This suggests that the immersion students are making a phonetic distinction in VOT between Japanese and English, though their VOT values are still intermediate, compared with the norms of the monolingual speakers and their immersion teachers. In other words, the immersion children implemented the VOT contrast differently from the model they were exposed to, that is, that of the Japanese English bilingual teachers. © Walter de Gruyter 2007.

    Harada, T

    Studies in Second Language Acquisition   28 ( 4 ) 601 - 632  2006.12  [Refereed]

     View Summary

    This study acoustically analyzed the production of single and geminate stops in Japanese by English-speaking children (N = 19) at three different grade levels in a Japanese immersion program. Results show that both their singletons and geminates were significantly longer than those of Japanese monolinguals and the bilinguals' immersion teachers, but all of the immersion groups have acquired the contrast between the two types of stop. This finding supports Flege's (1995) hypothesis that a phonetic category established for second language sounds by a bilingual might differ from that of a monolingual. Additionally, 52 native speakers of Japanese rated the contrast between the two stops produced by all of the bilingual children and a subset of the monolingual children. The accent ratings suggest that the contrast made by the immersion children was not native-like despite some individual differences in their performance and that there was no statistical difference in accent ratings across the grade levels. The degree of the contrast correlated fairly highly with the closure duration ratio of geminates to singletons.

  • Acoustic analysis of the production of unstressed English vowels by early and late Korean and Japanese bilinguals

    Borim Lee, Susan G. Guion, Tetsuo Harada

    Studies in Second Language Acquisition   28 ( 3 ) 487 - 513  2006.09  [Refereed]

     View Summary

    The production of unstressed vowels in English by early and late Korean- and Japanese-English bilinguals was investigated. All groups were nativelike in having a lower fundamental frequency for unstressed as opposed to stressed vowels. Both Korean groups made less of an intensity difference between unstressed and stressed vowels than the native speakers (NSs) of English as well as less of a difference in duration between the two types of vowel than the NSs. The Japanese speakers, whose native language has a phonemic length distinction, produced more nativelike durational patterns. Finally, the vowel quality (first and second formant frequencies) of unstressed vowels was different from the NS group's for the late bilinguals, for whom unstressed vowels were widely dispersed in the vowel space according to their orthographic representations, and from the early Korean bilinguals, who substituted the Korean high central vowel. The results are discussed in terms of the effect of the phonological status of first language phonetic features and age of acquisition.

  • Factors affecting stress placement for English nonwords include syllabic structure, lexical class, and stress patterns of phonologically similar words

    SG Guion, JJ Clark, T Harada, RP Wayland

    Language and Speech   46 ( 4 ) 403 - 427  2003  [Refereed]

     View Summary

    Seventeen native English speakers participated in an investigation of language users' knowledge of English main stress patterns. First, they produced 40 two-syllable nonwords of varying syllabic structure as nouns and verbs. Second, they indicated their preference for first or second syllable stress of the same words in a perception task. Finally, they indicated words they considered to be phonologically similar to the nonwords. Analyses of variance on the production and perception data indicated that both syllabic structure and lexical class (noun or verb) had an effect on main stress assignment. In logistic regression analyses on the production and perception responses, predictions of stress placement made by (1) syllable structure, (2) lexical class, and (3) stress patterns of phonologically similar words all contributed significantly and uniquely to the prediction of main stress assignment. The results indicate that phonological theories of English word stress need to allow for multiple, competing, probabilistic factors in accounts of main stress placement including syllabic structure (most notably vowel length), lexical class, and stress patterns of phonologically similar words.

     View Summary

    This is a project on the development of language skills by children in a Japanese English two-way immersion program. It consists of their speaking skills measured by the ACTFL Assessment of Performance toward Proficiency in Languages (AAPPL) and pronunciation accuracy obtained by acoustic analysis (i.e., voice onset time for [p, t, k] in both English Japanese). For the assessment of their speaking skills, many of the participants (85%) reached the level of at least I-2 or I-3 (Intermediate Mid), whereas the top 15% of them successfully reached the Intermediate High (I-5) level. For the analysis of VOT, though they did not develop their VOT values across grades, speakers of both Japanese as a foreign language (JFL) and Japanese as a heritage language (JHL) in the program produced VOT in the same way regardless of the place of articulation. In addition, the JFL learners successfully distinguished in VOT between English and Japanese.

     View Summary

    This study investigated effects of a younger starting age in a situation of minimal classroom exposure on the perception of English consonants produced by different talkers with two noise levels. The listeners were two groups of Japanese university students: early learners (n = 21) who started studying English in kindergarten or elementary school, and late learners (n = 24) who began to study in junior high school. The selected target phonemes were word-medial approximants (/l, r/). Results showed that the late learners discriminated /l/ and /r/ better than the early learners regardless of the noise conditions and talker differences (p < .05). A multiple regression analysis revealed that the late learners’ success could be accounted for by the following predictors: 1) classroom interaction with teacher and peers, 2) use of spoken English outside of classroom, and 3) overall English language proficiency. The age factor may not matter in the minimal input situation.

     View Summary

    The contribution of the current research is classfied into the following three:① the deepening of understanding of the concept of English as a lingua franca (ELF) ② detailed description and understanding of the use of ELF in actual situations and ③ heightening awareness of the use of ELF and impliacations for language pedagogy. The first has been mainly achieved by holding various workshops and publishing working papers based on them. The second has been made possible by collecting and analysing various types of data from diverse ELF users in their use of ELF and by showing how cooperatively and successfully they achieve their communicative needs. Thirdly, disseminating these results and their implications by way of conference presentations and publications has contributed to heightening the awarness of people about ELF and to furthering pedagogical implications.

     View Summary

    This study investigated long-term effects of childhood second language (L2) experience in an instructional setting on L2 pronunciation in adulthood. Specifically, it compared the production of Japanese speech sounds by English-speaking university students who had spent their early years in a Japanese immersion program (early learners) to that of English-speaking learners of university-level intermediate Japanese with no exposure to Japanese in childhood (late learners). Results did not confirm enough advantages in pronunciation for the early learners over the late learners despite a substantial amount of childhood experience in the immersion program.

     View Summary

    This study investigates the acquisition of second language(L2) speech in an immersion program from both phonetic and psycholinguistic points of view, and also tests the Speech Learning Model(SLM) hypothesized by Flege(1995). Specifically, the study examines whether or not English-speaking children in a Japanese immersion program, in which many content subjects are taught in Japanese, can successfully acquire segmental timing(i.e., voice onset time(VOT) and closure duration fur singletons and geminates) in Japanese, and can retain this ability despite the decrease of L2 input after they have exited the program. Data were collected from 15 children in a Japanese immersion program, 5 immersion teachers in the program, 10 Japanese monolinguals, 10 English monolinguals, and 10 English-speaking university students who exited a Japanese immersion program in elementary school(N=50). The informants were asked to repeat several target words with initial/p, t, k/for VOT, and medial/p, t, k/ and/pp, tt, kk/ for singletons and geminates in a sentence frame. Both VOT of the initial stops and closure duration of the medial stops were measured. The results show that 1) although both their singletons and geminates were significantly longer than those of the Japanese monolinguals, the immersion children acquired the contrast, and that 2) although they produced Japanese voiceless stops with significantly longer VOT values than the monolingual Japanese children, they produced them with significantly shorter VOT values than their English VOT. The findings suggest that 3) the bilingual children may have phonetic categories different from Ll speakers', which can be a L2 speaker's psychological strategy for differentiating between similar sounds in Ll and L2, and this will support Flege's SLM. Also, though the results are not conclusive, the immersion graduates seem to have retained their phonetic ability after they exited the program.

Specific Research

  • 公立学校におけるイマージョン教育の可能性

    2021  

     View Summary

    海外ではカリキュラムの少なくとも半分以上の教科学習を外国語で行うイマージョン教育が公立小学校で一般に行われている。一方、国内では私立学校でのイマージョン教育の導入は1990年代から始まっているが、公立学校での実施は皆無だった。しかし、2020年度に初めて愛知県豊橋市立八町小学校で日本語と英語を併用して授業を行う英語イマージョン教育が導入された。本研究の目的は八町小学校のカリキュラム内容やその実施方法を調べ、アメリカの公立学校のイマージョン教育と比較しながら、国内の公立学校におけるイマージョン教育の可能性を探ることにある。学校訪問を実施し、授業見学を行い、管理職、教員などに聞き取り調査を実施した。

  • 学習言語としての英語教育と継承言語教育のカリキュラム

    2020   高倉(林)あさ子

     View Summary

    在外教育施設の8万人を超える児童に対しての高度グローバル人材(文科省2017年「在外教育施設グローバル人材育成強化戦略」)の養成が不可欠であり、また「平成29年度在外教育施設の高度グローバル人材育成拠点事業」として高度なグローバル人材の育成を目的としてAG5という事業が発足している。このような状況では、単にコミュニケーションを重視した言語教育より、むしろ学習言語(教科学習の言語)としての英語教育また継承言語教育が求められている。本研究では、学習言語としての母語と外国語の習得を促す国内外の二言語教育のカリキュラムを広く検討し、国内外の学習言語としての英語教育と継承言語教育のあるべき姿を調査した。

  • 国際バカロレア(IB)とバイリンガル教育の比較

    2019  

     View Summary

     文科省は、グローバル人材育成の観点から、国際バカロレア(IB)を推進し、2020年までにIB認定校を200校以上にすることを目指している。この動きに拍車を掛けたのは、IBのディプロマ・プログラム(DP)を日本語と英語で実施できるDual Language DPである。英語以外の科目を英語で履修させるカリキュラムは、既に北米で長い歴史があるバイリンガル教育(とくに、イマージョン教育)や内容重視教育(CBI)、さらには最近注目されている内容言語統合学習(CLIL)と多くの共通点を持つ。本研究は、バイリンガル教育の観点からIBプログラムのカリキュラムを調査し、英語能力の習得と教科科目を英語で行なった場合の理解度に焦点を当て考察する。

  • 英語による専門科目の授業(EMI)で要求される音声語彙力の量的質的研究

    2018  

     View Summary

    本研究は、英語による専門科目の授業(EMI)を受講している学生の「読んで理解できる語彙力」と「聞いて理解できる音声語彙力」を測定した。一般的に、学術的な内容の英語を聞いて理解するには、最低4,000から5,000語程度のワードファミリーを音声語彙として理解できる必要がある(Dang &amp; Webb, 2014)。日本の大学のEMIの受講生の語彙力を把握するために、学部学生35名を対象に両者の語彙力を測定した。とくに音声語彙力は2,000語レベルでも正答率が90%以下で、講義の理解に要求されるレベルをかなり下回っていることが分かった。詳細は、Uchihara &amp; Harada (2018)を参照。

  • 英語による専門科目の授業(EMI)における学生と教員のサポート

    2017  

     View Summary

    最近早稲田大学も含めて様々な大学で専門科目を英語で開講する大学が急増しているが、本研究は学生と教員の両方に焦点を当て、前者は実際に英語による専門科目の授業(English medium instruction = EMI)を履修している学生の語彙力とEMIに参加した学生の方略(ストラティジ)を調べた。後者は、EMIに関する講演を依頼された際に、様々な教員側の問題点を、質疑応答や討論を通して探った。先行研究のEMIに必要な語彙力と比較すると、学生の語彙力はかなり不足しているが、様々なストラティジを使って乗り切っていることが判明した。一方、EMIを担当する専門科目の教員は、従来の英語教育からEMIへの移行プロセスを学び、EMI授業に向けて意識改革する必要がある。

  • 英語ディグリー・プログラム実現のためのファカルティ・ディベロプメントの基礎研究

    2016  

     View Summary

    ファカルティー・ディベロップメントの方法論を構築するために、今年度は、英語による専門科目の授業に4人の大学院生をファシリテーターとして参加させて、 教員として何が必要かを、授業を通して経験してもらった。学期の半ばには、 授業 についての詳細なアンケートを 実施し、一部の学生にはインタビューを実施した。 その結果、EMIを担当する教員が意識しなくてはならない問題がいくつか明らかになった。1)非英語圏で英語を媒介語として授業を行う場合、教員は学生の不安をいかに抑えるかを考慮する必要があり、2)内容理解や英語力の発達を考えると、授業中に行うタスクの順序(タスク・シークエンス)が重要であることが判明した。

  • Dual Language Programs(双方向二言語教育)の基礎調査研究-早期英語教育への示唆-

    2015  

     View Summary

    本研究では、双方向二言語教育(Two-Way Immersion: TWI)に在籍する両言語の児童が、1)目標言語、2)母語、3)教科を十分に学習することができるのかを文献調査により明らかにした。TWIプログラムは、一般に従来のイマージョン教育よりも効果があり、母語も目標言語も十分に習得でき、教科学習にも成功すると言われている(Lessow-Hurley, 2012)。たとえば、スペイン語と英語のTWIの研究報告の多くは、言語教育と教科教育の両面に於いて、スペイン語話者にも英語話者にも効果的だとしている(e.g., Cazabon, Nicoladis, &amp; Lambert, 1998; Genesee et al., 2006: Lindholm-Leary, 2001; Lindholm-Leary &amp; Block, 2010; Thomas &amp; Collier, 2002)。さらに、両言語の児童は、母語による学習能力も優れていると報告されている(Lindholm-Leary, 2001)。一方、アジア言語に関しては韓国語(Sohn &amp; Merrill, 2008)と中国語(Padilla, et al., 2013)のTWIの例がほとんどで、残念なことに日本語と英語の体系的な事例研究はなかった。

  • 幼児期から始める外国語教育の形態であるイマージョン教育での発音習得

    2005  

     View Summary

     最近幼児期から算数や理科等の学科目を外国語で教えるイマージョン教育が日本でも脚光を浴びるようになった。幼児期から外国語を始める理由に、児童が言語音声に対して大人より敏感であることが挙げられるが、5歳前後の早い時期から第二言語に触れても、明らかに外国語訛りが残るとされる研究結果もある。臨界期説は、目標言語が話されている国で、多くの言語のインプットがある場合で、インプットが限られているような外国語教育にそのまま当てはまるとは限らない。臨界期説の多くの研究は、自然な環境で言語を学ぶ場合で、イマージョン教育等の教室内で集中して学ぶ場合の音声習得は、明らかにされていない。目標言語に触れる量が多いイマージョン教育でも、自然な環境での言語習得と比べると、インプットの量やその質が異なるため、早期外国語教育の形態であるイマージョン教育に於いての外国語の音声習得過程を明らかにする必要がある。 本研究はイマージョン教育に於ける発音習得の研究を行い、英語を母語とする児童は、音声的には日本語的な特徴を完全に習得することはできないが、母語である英語の類似音とは範疇的に区別し、日本語と英語の別の音声体系を構築できることを確認した。日本語イマージョンの児童が発話した日本語と英語の語頭の/p, t, k/のVoice Onset Time (VOT)と日本語の促音の持続時間を音響分析した。さらに、促音に関しては母語話者による発音評価テストを行った。 VOTの習得に関しては、VOT の値が最も短いのが日本語母語話者の小学生、次に短いのが日本語イマージョンの教師(英語とのバイリンガル話者)、そして一番長いのが日本語イマージョンの児童であった。しかし、日本語イマージョンの児童は、英語と日本語の /p, t, k/ の特徴を確実に区別していて、しかもこの能力は既に1年生(学習時間1600時間)でほぼできあがっていた。また、イマージョンの児童の促音の閉鎖持続時間に関しては、促音と非促音が共に母語話者より長くなる傾向にあるため、その対立は必ずしも明瞭ではないが、音響的には促音と非促音の区別がなされていた。さらに、イマージョンの児童の促音の発音を日本語母語話者に評価しもらった結果、音響的には促音がある場合とない場合の区別ができているが、明らかに母語話者よりも評定が低く、母語話者が促音があるかないかを判定するのに困難を伴った場合もあった。さらに、学年間(1年生、3年生、5年生)に統計的に有意差がなく、幼稚園から5年生までの6年間の約4000時間を越えたインプットでも決して十分であるとは言えないようである。すなわち、音声的にまったく母語話者(monolingual speakers)と同じくなることはなく、Flege (2002) の完全なバイリンガルはいない(No perfect bilinguals)という説にも繋がる。しかしながら、早期学習や多量のインプットにより、母語と外国語の音声を少なくとも個人の音声体系の中で区別できるようになる可能性があるのは、早期言語教育の大きな貢献であろう。 現在,英語イマージョン教育に於ける日本語を母語とする児童の発音データーとイマージョン教育の幼稚園・小学校を卒業して大学に進学した学生がどの程度イマージョンプログラムで習得した音声が維持できているかのデーターも分析中である。
