Three kinds of knowledge that effective teachers should master have been proposed: content knowledge (CK), pedagogical knowledge (PK), and pedagogical content knowledge (PCK). Most PCK studies have been conducted in the mathematics or science domain. In recent years, a growing number of studies related to foreign language teachers' PCK have…

Two acoustic studies of voice onset time (VOT) in sibilant-stop (ST) consonant clusters, produced by first language (L1) speakers of Polish, are presented. In the first, a baseline study of L1 Polish comparing ST clusters with initial singleton stops, a small degree of VOT shortening after /s/ was found for /p/, but not /t/. The second study…

The Sylheti Bangla, a variety of Bangla language is primarily spoken in the Sylhet District of Bangladesh, Barak Valley of Assam, Tripura, especially in North Tripura. The systematic perusal on English spoken by Sylheti Bangla speakers demonstrates that it carries a huge difference with English (RP) specially in respect to pronunciation, syllable…

Previous event-related potentials (ERP) research has investigated how foreign accent modulates listeners' neural responses to lexical-semantic and morphosyntactic errors. We extended this line of research to consider whether pronunciation errors in Mandarin Chinese are processed differently when a foreign-accented speaker makes them relative to…

Three categories of audio recordings, a web service platform, and commercial software were involved in this analysis process. The three categories of audio recordings included eight filtered student recordings, an audio recording provided by a Mandarin instructor from University Malaysia Sabah, and an audio recording generated by Text-to-Speech…

This study investigated how adult second language (L2) learners of Mandarin Chinese use knowledge of phonological and lexical statistical regularities when acoustic information is insufficient for word recognition. A gating task was used to test intermediate L2 learners at two time points across a semester of classroom learning. Native Mandarin…

This article extends Optimality Theoretic studies to the research on second language tone phonology. Specifically, this work analyses the acquisition of identical tone sequences in Mandarin Chinese by adult speakers of three non-tonal languages: English, Japanese and Korean. This study finds that the learners prefer not to use identical lexical…

This article reports on teachers' knowledge and perceptions and the issues they are concerned about in relation to pronunciation teaching. Understanding teacher cognition helps to ensure research and pedagogical advice are appropriately directed. However, there has been only a limited amount of research in this area. The researcher collected data…

This study determines the fine-grained bottom-up linguistic features involved in successful second language (L2) English academic group oral tutorial discussion through the use of a spoken learner corpus composed of more than 20 hrs of L2 production. Student performances were graded by teacher-raters using a can-do rating scale, which assessed…

The current study longitudinally examined the influence of aptitude on second language (L2) pronunciation development when 40 first-year Japanese university students engaged in practice activities inside and outside English-as-a-Foreign-Language classrooms over one academic year. Spontaneous speech samples were elicited at the beginning, middle,…

The current study investigated first language (L1) effects on listener judgment of comprehensibility and accentedness in second language (L2) speech. The participants were 45 university-level adult speakers of English from three L1 backgrounds (Chinese, Hindi, Farsi), performing a picture narrative task. Ten native English listeners used…

Every language has its own rhythm. Unlike many other languages in the world, English depends on the correct pronunciation of stressed and unstressed or weakened syllables recurring in the same phrase or sentence. Mastering the rhythm of English makes speaking more effective. Experiments have shown that we tend to hear speech as more rhythmical…

This dissertation investigated the effects of technological mediation on second language (L2) learning, focusing, as a case study, on gains in listening perception of the subtle but important feature of pitch placement in Japanese. Pitch accent can be difficult to perceive for non-native speakers whose first language (L1) does not rely on pitch or…

This dissertation explores the second language acquisition of Mandarin Chinese tones by speakers of non-tonal languages within the framework of Optimality Theory. The effects of three L1s are analyzed: American English, a stress-accent language; Tokyo Japanese, a lexical pitch accent language; and Seoul Korean, a non-stress and non-pitch accent…

This qualitative case study investigates Chinese university English in the context of foreign language (EFL) learners' attitudes about video-aided instruction (VAI), video recording instruction, and mobile phone instruction (learning technologies). When I was working as an English teacher in Mainland China, several instructors and students stated…
