This dissertation investigated 1) American L2 learners' perceptual ability to accurately identify Japanese pitch accent, and 2) learners' realization of Japanese pitch accent. This study was conducted to determine whether these abilities could be improved through training. Study 1 tested the ability to identify the accent location (pitch fall)…

This research involved two observational studies. It explored the scaffolding processes as part of classroom pedagogy. The research shed light on the way a teacher's instructional methodology took shape in the classroom. The target event for this study was the time in which a novice learner was engaged publicly in uttering a sentence in Arabic in…

This paper describes My Science Tutor (MyST), an intelligent tutoring system designed to improve science learning by students in 3rd, 4th and 5th grades (7 to 11 years old) through conversational dialogs with a virtual science tutor. In our study, individual students engage in spoken dialogs with the virtual tutor Marni during 15 to 20 minute…

This study assessed, in a sample of 98 adult native speakers of Dutch, how their lexical skills and their speaking proficiency varied as a function of their age and level of education and profession (EP). Participants, categorized in terms of their age (18-35, 36-50, and 51-76 years old) and the level of their EP (low versus high), were tested on…

The No Child Left Behind (NCLB) Act (US Government, 2001), the current iteration of the Elementary and Secondary Education Act of 1965, makes it clear that states, districts, schools and teachers are accountable for the education of English language learners (ELLs), as well as all other students. To implement an accountability system, NCLB…

This study investigates the relationship between acculturation and language learning during a year-long study abroad program at the pre-collegiate level. The researcher presents the experiences of four U.S. American sojourners to Sweden as case studies. This mixed-methods study looks specifically at students with no prior knowledge of the target…

This article describes the phonological awareness and English writing skills among a sample of 297 Singaporean kindergarten children, stratified by ethnicity (Chinese, Malay, and Indian), and examines the relationship between oral language and writing skills in this multilingual population. Overall, Singaporean kindergartners, nearly all of whom…

Morphological variability and the source of these errors have been intensely debated in SLA. A recurrent finding is that postpuberty second language (L2) learners often omit or use the wrong affix for nominal and verbal inflections in oral production but less so in written tasks. According to the missing surface inflection hypothesis, L2 learners…

This study examines how listener judgments of second language speech relate to individual differences in listeners' phonological memory, attention control, and musical ability. Sixty native English listeners (30 music majors, 30 nonmusic majors) rated 40 nonnative speech samples for accentedness, comprehensibility, and fluency. The listeners were…

The purpose of this study was to explore patterns of within-group variability in the emergent literacy skills of preschoolers who are at risk for academic difficulties. We used the person-centered approach of cluster analysis to identify profiles of emergent literacy skills, taking into account both oral language and code-related skills.…

This article contributes to the literature on the use of the present tense to refer to past events in oral narratives, otherwise known as the Conversational Historical Present (CHP) (Wolfson 1978). Previous research has found that the CHP switches with the past (Wolfson 1979) frequently with verbs of saying and achievement verbs (Dunn 1998; Van…

The purpose of this study is to examine the perception and production of Japanese geminate and single consonants by learners of Japanese in various proficiency levels. Research on Japanese geminate and single stop consonants show that geminates and single stop consonants are significantly difficult for nonnative Japanese speakers to produce and…

This paper focuses on the education of the deaf pupils at Casa Pia de Lisboa, a Portuguese boarding-school, covering the period from 1820 to 1950. The intention is to show that a historical sedimentation of a scientific discourse about deafness is an effect of a new rationality of government begun by modernity and perfectly fitting a bio-political…

Purpose: This study examined false belief understanding and its predictors in school-age children who are deaf with cochlear implants and who use spoken language. Method: False belief understanding was measured through an explanation-of-action task in 30 children between the ages of 3 and 12 years who used cochlear implants. Children told a…

The extant literature on oral and written language has shown several interesting differences in terms of production and style. The purpose of the present study was to investigate the content of word definitions provided by children in both the oral and written modes. A total of 30 typically developing children (mean age: 9 years; 2 months) defined…
