This paper compares two alternative scoring methods--multiple regression and classification trees--for an automated speech scoring system used in a practice environment. The two methods were evaluated on two criteria: construct representation and empirical performance in predicting human scores. The empirical performance of the two scoring models…

A questionnaire study was conducted to examine how 120 highly experienced EFL (English as a foreign language) teachers in Japan adjust their pronunciation in order to facilitate and refine their students' learning skills to approach mutual intelligibility in second language (L2) classrooms (i.e. "pronunciation-specific teacher talk").…

The study examined individual differences in code-switching to determine the relationship between code-switching frequency and performance in verbal and non-verbal task switching. Seventy-eight Cantonese-English bilinguals completed a semi-structured conversation to quantify natural code-switching, a verbal fluency task requiring language…

A major issue that continues to challenge language teachers is how to ensure that learners develop accuracy and complexity in their speaking, as well as fluency. Teachers know that too much corrective feedback (CF) can make learners reluctant to speak, while not enough may allow their errors to become entrenched. Furthermore, there is controversy…

Thirty-three students of fourth semester German at the University of Kansas participated in the study which sought to investigate whether focused written corrective feedback (WCF) promoted the acquisition of the German case morphology over the course of a semester. Participants received teacher WCF on five two-draft essay assignments under three…

This exploratory study focuses on four non-native English speaking secondary content teachers in a short-term immersion program aimed at introducing them to language teaching methods for secondary school content instruction through the medium of English. Such programs have been found to have largely mixed results for language performance. This may…

Oral fluency and foreign accent distinguish L2 from L1 speech production. In language testing practices, both fluency and accent are usually assessed by raters. This study investigates what exactly native raters of fluency and accent take into account when judging L2. Our aim is to explore the relationship between objectively measured temporal,…

This study examined metalinguistic awareness in children who were becoming bilingual in an immersion education program. The purpose was to determine at what point in emerging bilingualism the previously reported metalinguistic advantages appear and what types of metalinguistic tasks reveal these developmental differences. Participants were 124…

Applied linguists have identified three components of second language (L2) performance: complexity, accuracy, and fluency (CAF) to measure L2 development. Many studies researching CAF found trade-off effects (in which a higher performance in one component corresponds to lower performance in another) during tasks, often in online oral language…

This chapter will present a research synthesis of a series of studies, termed here the Ealing research. The studies use the same general framework to conceptualise tasks and task performance, enabling easier comparability. The different studies, although each is self-contained, build into a wider picture of task performance. The major point of…

The present study examined various aspects of the development of learners' fluency in Japanese using a large set of speech samples collected over a long period, using an online speaking practice/assessment system called "Speak Everywhere." The purpose of the present study was to examine: (1) how the fluency related measures changed over…

California is poised to become the first state to unmask the extent to which English-language learners (ELLs) languish in public schools for years without ever reaching fluency. Under a measure that received broad, bipartisan support from the legislature, the state education department would be required to break out and report data annually on…

We used structural magnetic resonance imaging (MRI) and voxel based morphometry (VBM) to investigate whether the efficiency of word processing in the non-native language (lexical efficiency) and the number of non-native languages spoken (2+ versus 1) were related to local differences in the brain structure of bilingual and multilingual speakers.…

On-line virtual 3D worlds offer the opportunity for users to interact in real time with native speakers of the language they are learning. In principle, this ought to be of great benefit to learners, and mimicking the opportunity for immersion that real-life travel to a foreign country offers. We have very little research to show whether this is…

Critics argue that requiring subjects to verbalize their thoughts while completing certain language tasks increases the participants' cognitive load and impairs their final performance (e.g., Jourdenais, 2001). Despite the importance of this claim for language instructors, few studies have produced contradicting evidence after an empirical study…
