摘要：Despite the popularity of task-based language teaching (TBLT) in foreign language (FL) education at elementary school, it remains unclear how young learners' FL abilities can best be evaluated with tasks. The present study seeks to understand developmental differences in interactions among elementary-school students during task-based language assessment (TBLA) and aims to address the possibilities and limitations of introducing paired-TBLA among young FL learners. The participants were 32 fourth-grade students (ages 9-10) and 32 sixth-grade students (ages 11-12) and their teachers from a FL program where TBLT was mandated. The students were engaged in two sets of assessment tasks with their peers. It was found that the interaction patterns were different between the two grade levels. Compared with the sixth-grade dyads, the fourth-grade dyads showed less mutual topic development, used formulaic turn-taking more frequently, and had a harder time taking their partners' perspectives during the tasks. Consequently, a smaller variety of interactional functions were observed among the fourth graders. The potential for eliciting a wide range of interactional functions, which is a primary advantage of introducing paired assessment, may have limited application for younger dyads. The study also discusses the strategic roles that such interactional characteristics may play among younger learners. Adapted from the source document

摘要：This study looks at the effect of developing L2 listening fluency through extensive listening to audio graded readers. A large bank of listening fluency development questions (2,064 items) was constructed based on ten Level 1 graded readers. Three groups of L2 students were engaged in one of three different input modes while studying ten graded readers over a 13-week period: reading only, reading while listening, and listening only. All participants were given one pre-test (60 items) before the intervention and one post-test consisting of three texts (180 items) after the intervention. All the passages were delivered at the same speech rate, and the participants were allowed to listen only once. The post-test results demonstrate that the reading plus listening group produced the most consistent and significant outcome compared with the reading-only and listening-only groups. The results have some implications for developing L2 listening fluency. Adapted from the source document

摘要：This study explores the differential effects of medium of delivery of aural input during listening tasks on learners noticing and type of comprehension (top-down and bottom-up) of Spanish object pronouns during focus on form listening tasks. Twenty-two college students enrolled in second year Spanish in a technology-enhanced classroom participated in the study. Two types of medium of delivery of input were compared: mobile assisted language learning (MALL), which is learner manipulated, and instructor manipulated language learning (IMLL). A quasi-experimental design was used -- treatment and immediate tests -- in order to measure participants' reported noticing and type of comprehension. Noticing was operationalized using think-aloud protocols, and measured on the post-test exposure comprehension assessment tasks. The findings of the study, interpreted within the attentional SLA framework, indicate that learners in the MALL group demonstrated significantly higher levels of reported noticing, bottom-up comprehension, and top-down overall comprehension than learners in the IMLL group. Directions for future research as well as pedagogical implications of the use of mobile technology and task-based listening activities are offered. Adapted from the source document

摘要：Studies undertaken since the introduction of Web 2.0 have focussed mainly on open educational resources (OERs) such as email, blogging and virtual learning environments. No consistent efforts have been undertaken to study the use of social networking sites as a tool for learning in the second language classroom. This study examined the use of social networking sites as a means of establishing an asynchronous online environment for use in language learning in a classroom setting. The findings described are based on the use of a social networking site called Ning in a classroom during a summer school project, which was conducted at a further education college in the UK. The project focussed in particular on informal language practice when using social networking sites. The paper then examines the effect the use of the social networking tool had on group cohesion and learner-to-learner interaction, and how these, in turn, enhanced informal language learning due to an increase in learner collaboration. The study found that the use of Ning enhanced group cohesion and that learners started working in different groups once Ning was introduced. Finally, it highlights the potential technical and administrative barriers that can impede an institution in implementing its educational strategy in regards to OERs -- in this case, social networking sites in the classroom. The further education college in which this study took place had no policies in place in regards to the use of OERs in the classroom, thus the paper concludes with recommendations in regards to training and policies so that researchers and practitioners can learn from the project.

摘要：This study investigated how synchronous computer-mediated communication (SCMC) and face-to-face (F2F) oral interaction influence the way in which learners collaborate in language learning and how they solve their communicative problems. The findings suggest that output modality may affect how learners produce language, attend to linguistic forms, and solve communicative problems. In particular, the use of collaborative processes to construct utterances was more prevalent in F2F interaction than in SCMC. Moreover, learners engaged in activities and produced language differently depending on output modalities, which differed in terms of the physical, social, and interactional contexts that they created and the way in which they influenced learners' communication strategies. The findings indicate that SCMC should be used selectively according to the pedagogical purpose. Adapted from the source document

摘要：The assignment of grammatical functions has been a key feature of hierarchical (serial) models of speech production since their inception in the 1970s. This article argues that grammatical function assignment is neither sufficient nor necessary in such models. It reports a study of the effects of the conceptual accessibility of referents on the selection of English dative syntactic frames in production and shows that the effects relate to linear precedence rather than grammatical function assignment. A secondary topic addressed in the same study is whether second language speakers of English have difficulty integrating syntactic knowledge where it interfaces with conceptual accessibility in speech production. Findings suggest that advanced proficiency speakers do not and are qualitatively similar to native speakers. The implications of this for the interface hypothesis about second language acquisition are discussed. Adapted from the source document

摘要：The extent to which risk for French as a second language (L2) reading and language learning impairment are distinct and can be predicted using first language (L1) predictors was examined in English-speaking students in total French immersion programs. A total of 86 children were tested in fall of kindergarten, spring kindergarten, and spring Grade 1 using an extensive battery of L1 predictor tests (in kindergarten) and L2 outcome tests (in Grade 1). Analyses of the kindergarten predictor scores revealed distinct underlying components, one related to reading and one to oral language. Further analyses revealed that phonological awareness, phonological access, and letter-sound knowledge in L1 were significant predictors of risk for reading difficulties in L2 while performance on L1 sentence repetition, phonological awareness, and tense marking tests in kindergarten were the best predictors of risk for L1 and L2 oral language difficulties. Both fall- and spring-kindergarten predictors predicted Grade 1 outcomes to a significant extent, with the spring-kindergarten predictors being more accurate. These results provide support for distinctive risk profiles for L2 oral language and reading difficulty and, furthermore, argue that assessment of L1 abilities can be used to make reasonably accurate predictions of later reading and/or oral language learning difficulties in L2 students.

摘要：Children's status as research participants in applied linguistics has been largely overlooked even though unique methodological and ethical concerns arise in projects where children, rather than adults, are involved. This article examines the role of children as research participants in applied linguistics and discusses the limitations of traditional research 'on' and 'about' children, using research studies as examples published in mainstream applied linguistics journals. As neighbouring fields have already embraced a new approach to children as 'active participants', it is essential that SLA also widens its research agenda by focussing on children as active social agents who are capable of taking more responsible roles in research that concerns their own language learning. The last section of the article examines studies 'with' and 'by' children outside SLA in some detail and suggests future directions for research within SLA, based on the epistemology of plurality and on developing a dialogic relationship between adult facilitators and children.

摘要：This article is part of a longitudinal study of American college students studying Mandarin in China. Its main data are drawn from monthly speaking events (four sessions with each student) conducted in Chinese with each of 29 participants in a study-abroad program in China. The study yielded these results: (a) Students made significant progress in their fluency development, especially during the first month; (b) speaking Chinese both inside and outside of class helped fluency; (c) students who consistently spoke Chinese in class and out of class made more progress than those who did not; and (d) time on task, the amount of time that students spent using Chinese, was the most important factor in determining fluency development. The quantitative analysis that is the focus of this article is supplemented by qualitative data from individual students, reflecting the position that only a combination of quantitative and qualitative data can reveal a complete picture of the nature of language acquisition during study abroad. The article concludes with implications for the design and conduct of programs in China.

摘要：This study investigated whether learners of Japanese with different first language (L1) writing systems use different recognition strategies and whether second language (L2) exposure affects L2 kanji recognition. The study used a computerized lexical judgment task with 3 types of kanji characters to investigate these questions: (a) pseudo-homophones, (b) pseudo-homographs, and (c) real words. Three groups of learners participated in the study: (a) beginning-level learners of Japanese whose L1 was alphabetic, (b) beginning-level learners of Japanese whose L1 was logographic, and (c) intermediate-level learners of Japanese whose L1 was alphabetic. The results showed that both levels of learners whose L1 was alphabetic had poor results on the computerized lexical judgment test, possibly due to poor L2 orthographic awareness. The learners with L1 alphabetic knowledge used a poor visual recognition strategy for L2 kanji decoding, whereas those with L1 logographic knowledge were able to access individual kanji characters due to sufficient knowledge of the characters. Some of the learners also preferred phonological coding to recognize kanji characters. In addition, reaction time for the judgment task differed significantly between beginning- and intermediate-level learners. Results indicated that different reading strategies were used by learners of L1 alphabetic or logographic backgrounds and the beginning and intermediate learners who had had different degrees of exposure to the L2.

摘要：The present study explores the use of conjunctions in simple versus complex argumentative tasks performed by second language (L2) learners as a specific measure for the amount of reasoning involved in task performance. The Cognition Hypothesis (Robinson, 2005) states that an increase in cognitive task complexity promotes improvements in L2 performance. This effect should become particularly visible when task-specific performance measures are used (Robinson & Gilabert, 2007). This article evaluates these claims by investigating the oral performance of 64 L2 learners on cognitively simple, as compared with cognitively complex, oral argumentative reasoning tasks. The analysis focuses first on the overall frequency and occurrence of conjunctions. Next, 5 conjunctions that are considered to be highly task-relevant are examined more closely. Results are discussed in light of the speech production of 44 native speakers who performed the same tasks under the same conditions. The discussion addresses implications of the findings for the cognitive approach to task-based L2 research in light of Robinson's (2005) Cognition Hypothesis. From the standpoint of research methodology it highlights the benefits of native speaker data as a baseline for comparison.

摘要：This study investigates whether practice with computer-administered feedback in the absence of meaning-focused interaction can help second language learners notice the corrective intent of recasts and develop linguistic accuracy. A group of 218 beginning Anglophone learners of Spanish received 1 of 4 types of automated feedback (no feedback, utterance rejection, recasts, or enhanced recasts) in the written mode or the oral mode, in response to noun-adjective gender or number agreement errors. For both modalities, written and oral posttests conducted up to 2 months after treatment revealed that recasts yielded more target-like production and learner repair than either no feedback or utterance rejection and that utterance rejection was in turn more effective than no feedback. Two factors were found to increase the effectiveness of computer-delivered recasts: oral, but not typographical, input enhancement (orally enhanced recasts were more beneficial than orally unenhanced and typographically enhanced recasts) and working memory (higher span learners were superior to lower span learners in all recast groups). We discuss the implications of our results for the area of error treatment as an instructional focus technique and suggest avenues for future research.

摘要：This study investigates whether native Hmong speakers' first language (L1) lexical tone experience facilitates or interferes with their perception of Mandarin tones and whether training is effective for perceptual learning of second (L2) tones. In Experiment 1, 3 groups of beginning level learners of Mandarin with different L1 prosodic background (Hmong, Japanese, and English) took a perception test on Mandarin tones. Both the English and Japanese groups outperformed the Hmong group in perceptual accuracy of Mandarin tones. In Experiment 2, 18 learners with different L1 background received either perception training only or perception with production training on Mandarin tones for 6 hours within 3-4 weeks. Both training paradigms were effective for perceptual learning of Mandarin tone contrasts as the two training groups' perceptual accuracy improved significantly at posttest compared with a control group. Although Hmong speakers initially had more difficulties in perception of Mandarin tones than the other 2 groups, they are by no means disadvantaged by their L1 prosodic background as they gain L2 experience after intensive training.

摘要：In this study I examine the construct of aptitude in learning Chinese as a second language (L2) to an advanced level. I test 2 hypotheses: first, that L2 aptitude comprises 4 components -- working memory, rote memory, grammatical sensitivity, and phonemic coding ability -- and second, that L2 aptitude affects learning both directly and indirectly (mediated by strategy use and motivation). Native speakers of English (n = 96) studying advanced Chinese took the Modern Language Aptitude Test and a phonological working memory test and responded to motivation and strategy use questionnaires. Using end-of-course listening, reading, and speaking proficiency test results as measures of Chinese learning, I constructed a structural equation model to test the hypotheses. The model fit the observed data. Of the 4 components foreseen to comprise L2 aptitude, rote memory contributed the most and working memory the least. Aptitude, strategy use, and motivation had about the same impact on learning but varied in how well they predicted the individual skills of listening, reading, and speaking. The results shed light on L2 aptitude in the particular context of an advanced L2 Chinese course.

摘要：This study investigates caption-reading behavior by foreign language (L2) learners and, through eye-tracking methodology, explores the extent to which the relationship between the native and target language affects that behavior. Second-year (4th semester) English-speaking learners of Arabic, Chinese, Russian, and Spanish watched 2 videos differing in content familiarity, each dubbed and captioned in the target language. Results indicated that time spent on captions differed significantly by language: Arabic learners spent more time on captions than learners of Spanish and Russian. A significant interaction between language and content familiarity occurred: Chinese learners spent less time on captions in the unfamiliar content video than the familiar, while others spent comparable times on each. Based on dual-processing and cognitive load theories, we posit that the Chinese learners experienced a split-attention effect when verbal processing was difficult and that, overall, captioning benefits during the 4th semester of language learning are constrained by L2 differences, including differences in script, vocabulary knowledge, concomitant L2 proficiency, and instructional methods. Results are triangulated with qualitative findings from interviews.

摘要：Laufer and Nation (1995) proposed that the Lexical Frequency Profile (LFP) can estimate the size of a second-language writer's productive vocabulary. Meara (2005) questioned the sensitivity and the reliability of LFPs for estimating vocabulary sizes, based on the results obtained from probabilistic simulations of LFPs. However, the underlying mathematical model for the simulations, based on Zipf's law, allows such an analysis to be done directly, without recourse to simulations. The direct analysis has the further advantage of demonstrating how variability estimates obtained from within the 1k band (the 1,000 most frequent words of English) portion of written texts may explain the simulation results. The findings confirm that the ability of LFPs to distinguish between groups diminishes as vocabulary size increases. However, for fairly homogeneous groups, LFPs are able to provide a coarse but reasonable tool for vocabulary size estimation. We also explore modifications to Zipf's law that may result in a more accurate model of word frequencies in natural language.

摘要：We examined negative transfer from English and Spanish to Portuguese pronunciation. Participants were native English speakers, some of whom spoke Spanish. Participants completed a computer-based Portuguese pronunciation tutorial and then pronounced trained letter-to-sound correspondences in unfamiliar Portuguese words; some shared orthographic form with their translation in Spanish or Spanish and English. Spanish-speaking participants were more accurate and made more Spanish-like than English-like errors. Contrary to predictions, non-Spanish speakers made more Spanish-like than English-like errors on cognates. Participants with higher working memory were more accurate and made more Spanish-sounding errors on cognates. The results suggest that the first language is inhibited during second-language production and that higher working memory is associated with an improved ability to inhibit the first language.

摘要：This study examines the roles of proficiency and working memory (WM) capacity in second-/foreign-language (L2) learners' processing of agreement morphology. It investigates the processing of grammatical and ungrammatical short- and long-distance number agreement dependencies by native English speakers at two proficiencies in French, and the relationship between their proficiency and WM capacity in French and their sensitivity to agreement violations. Native English speakers at mid- and high proficiencies in French and native French speakers completed an acceptability judgment task, a self-paced reading task, and a WM task in French, and the English speakers also completed a WM task in English. The results showed that whereas all participants performed at ceiling on the acceptability judgment tasks, only the high-level L2 learners and native speakers showed some sensitivity to number agreement violations. For L2 learners, this sensitivity did not vary as a function of the length of the agreement dependency. The results also indicated that L2 learners tended to be more sensitive to agreement violations as their WM memory capacity in French increased. The implications of these results for theories of L2 morphological processing are discussed.

摘要：Although wh-words generally stay in situ in Chinese wh-questions, they can be topicalized. However, the wh-topicalization is determined at the syntax-discourse interface and has to be governed by discourse conditions; only discourse-linked (D-linked) wh-words can be topicalized, but non-D-linked ones cannot. This article reports on an empirical study that investigated English speakers' second language (L2) acquisition of Chinese wh-topicalization. The results of an acceptability judgment test indicate that advanced English speakers are sensitive to the discourse condition that governs the syntactic derivation of wh-topicalization in Chinese, as they were found to be able to make the distinction in their L2 Chinese by allowing D-linked, but not non-D-linked, wh-elements to topicalize. However, these results also indicate that wh-determiner phrases (DPs) and wh-noun phrases (NPs) differ in their sensitivity to presupposition background information in L2 Chinese wh-topicalization, and it is argued that the availability of the deictic feature in the wh-element involved is a variable affecting the D-linking properties of wh-elements in the development of L2 Chinese wh-topicalization, and this seems more likely to be a representational deficit than a processing problem.

摘要：This meta-analytic study provides a systematic statistical synthesis of the effects of output tasks on second or foreign incidental vocabulary learning. A total of 12 studies were included in this meta-analysis. Five mediator variables were examined: design quality, types of output task, time on task, genres of text, and text-target word ratios. Results show that language learners who completed an output task outperformed those who only read a text. Results also support the involvement load hypothesis: Language learners who performed a task with a higher degree of involvement load, gained more vocabulary. Studies with high and medium levels of design quality were more likely to detect statistically significant differences among groups with different output tasks, compared to studies with a low level of design quality. Furthermore, results indicate that time on task had positive effects on vocabulary learning. Learners who read a combination of expository and narrative text gained more vocabulary than those who only read either an expository or narrative text. Learners who read a text with text-target word ratios of less than or equal to 2% did not learn significantly more vocabulary than those who read a text with a ratio of 2% to 5%.
