This study investigated Task-Based Language Learning (TBLL) through Digital StoryTelling (DST) in a blended learning environment. Twenty-six Turkish university-level students prepared a DST individually and shared it with their peers in an online discussion platform. Each evaluated and graded others' DST performance based on an assessment scale.…

Language exposure plays a large role in language acquisition, and bilingual children must acquire both of their languages in environments that typically include abundant speech variability. The specific goals of this dissertation were to examine how speech exposure affected phonological retuning and lexical access in bilingual children's second…

A key piece of a validity argument for a language assessment tool is clear overlap between assessment tasks and the target language use (TLU) domain (i.e., the domain description inference). The TOEFL 2000 Spoken and Written Academic Language (T2K-SWAL) corpus, which represents a variety of academic registers and disciplines in traditional…

This study examined the role of visual cues (facial expressions and hand gestures) in second language (L2) speech assessment. University students (N = 60) at English-medium universities assessed 2-minute video clips of 20 L2 English speakers (10 Chinese and 10 Spanish speakers) narrating a personal story. They rated the speakers'…

Research attempting to understand the intermediate stages of first-language acquisition and disordered speech has led to the discovery of covert contrast. A covert contrast is a statistically reliable difference between phonemes that is produced by a language learner, but in a way that cannot be heard readily by a listener of the target language.…

Spanish native speakers are known to pronounce onset /sC/ clusters in English with a prothetic vowel, as in "esport" for sport, due to their native language phonotactic constraints. We assessed whether accurate production of e.g. "spi" instead of "espi" was related to accurate perceptual discrimination of this…

In this study we investigated the potential for a shared-first-language (shared-L1) effect on second language (L2) listening test scores using differential item functioning (DIF) analyses. We did this in order to understand how accented speech may influence performance at the item level, while controlling for key variables including listening…

Nonverbal and other visual cues are well established as a critical component of human communication. Under most circumstances, visual information is available to aid in the comprehension and interpretation of spoken language. Citing these facts, many L2 assessment researchers have studied video-mediated listening tests through score comparisons…

Prosody communicates pragmatic meaning far beyond that which is evident at the surface level of an utterance and can pose challenges to learners' pragmatic comprehension. The current study investigated how second language (L2) English learners made decisions about speaker intent when communicated through prosody. Seventeen English L2 learners took…

Second language classroom interaction has unique characteristics. The purpose of this paper is to describe the linguistic resources that teachers draw on to encourage social interaction in the EFL classroom. This examination includes a detailed analysis of the practical activities teachers engage in, focusing on their use of linguistic repertoires…

Traditionally, pronunciation is taught through recognition- or repetition-based mechanical drills. Upon the arrival of the communicative approach, pronunciation has been neglected in the ELT classroom because these types of activities are considered uncommunicative and form-focused. The teachers and coursebooks, however, have failed to replace…

This paper examines the differences correlation between instructor- and peer-based participation scores and oral proficiency in an EFL course focusing on oral communication. It finds that there is very little correlation between instructor-based and peer-based participation scores (r = 0.187, p = 0.053) and that the former is more associated with…

While recent research has shown that multimodal feedback and use of formulaic sequences (FS) are effective in improving student performance on writing tasks, there is a dearth of studies on the impact of these aspects on computer-based academic speaking assessments. This dissertation seeks to fill this gap by examining the impact of both…

This study investigates how second language (L2) listeners' perception is affected by two factors: the listeners' experience with the target dialect -- North American English (NAE) vs. Standard Southern British English (SSBE) -- and talkers' language background: native vs. non-native talkers; i.e. interlanguage speech intelligibility benefit…

This paper reports on a blended learning approach for public speaking in an English as a foreign language (EFL) context. The researcher implemented the course design through reduced weekly face-to-face class sessions and online student interaction using a speech video-based blog. Using a survey conducted at the end of the semester, multiple…
