摘要：This study examines the effects of interactive versus simultaneous display of visual and verbal multimedia information on incidental vocabulary learning and reading comprehension of learners of English with lower proficiency levels. In the interactive display condition, learners were allowed to select the type of multimedia information whereas the simultaneous display condition presented the verbal (definitions) and visual (associated pictures) information in a single gloss. Eighty-two students were randomly assigned to the treatment conditions and were asked to read an annotated expository text. Reading comprehension was measured through a recall protocol and a multiple-choice test. Incidental vocabulary learning was measured through unannounced vocabulary tests of form recognition, meaning production, definition match, and bilingual synonym match. T-tests and ANOVA analyses indicated that the participants utilized glosses less frequently when they were given the control over access to the type of multimedia information. In addition, simultaneous display of multimedia information led to better performance on reading and vocabulary tests. The results are in line with the contiguity principle of Generative Theory of Multimedia Learning, which posits that presenting verbal and visual information simultaneously reduces cognitive load and results in better learning. The findings have implications for both the development of multimedia materials for L2 learners and training of learners to interact with multimedia materials. Adapted from the source document

摘要：This study examines vocabulary growth rates in first and second languages for Spanish-speaking and Cantonese-speaking English language learners from kindergarten through second grade. Growth-modeling results show a within-language effect of concepts about print on vocabulary. Language exposure also had an effect on English vocabulary: earlier English exposure led to larger English vocabulary in kindergarten. There was no interference of early English exposure on native-language vocabulary. Moreover, Cantonese-speaking children had higher English expressive vocabulary scores than Spanish-speaking children and this difference remained for the 3 years. In contrast, although there were no significant differences in first language vocabulary at the start of kindergarten, Spanish-speaking children had steeper growth rates in first-language vocabulary than Cantonese-speaking children, after controlling for language of instruction and first-language concepts about print.

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：This article compares the effects of listening and reading on the incidental acquisition and retention of vocabulary. Two hundred thirty students participated in the study: They either (a) read three academic texts, (b) watched three lectures, or (c) received no input at all and just completed the vocabulary measures. This study also assessed and compared the relationship between acquisition through each of these presentation modes and the following factors: frequency of occurrence, type of word, type of elaboration, and predictability from word form and parts. The reading subjects made greater vocabulary gains than the listening subjects for all four levels of proficiency analyzed. Inspection of pairwise comparisons seemed to indicate that the difference in gains between the reading and listening conditions decreased as the students' proficiency increased. Similar trends emerged for retention. Reading also resulted in greater retention 1 month after the input, except for the highest proficiency students. For this group, no significant difference was found between the listening and reading delayed posttest scores. The relationship among each of the four factors was analyzed and vocabulary acquisition was also found to vary across input modes.

摘要：The close relationship between children's vocabulary size and their later academic success has led researchers to explore how vocabulary development might be promoted during the early school years. We describe a study that explored the effectiveness of naturalistic classroom storytelling as an instrument for teaching new vocabulary to 6- to 9-year-old children. We examined whether learning was facilitated by encountering new words in single versus multiple story contexts, or by the provision of age-appropriate definitions of words as they were encountered. Results showed that encountering words in stories on three occasions led to significant gains in word knowledge in children of all ages and abilities, and that learning was further enhanced across the board when teachers elaborated on the new words' meanings by providing dictionary definitions. Our findings clarify how classroom storytelling activities can be a highly effective means of promoting vocabulary development.

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%.

摘要：OpenCourseWare (OCW) has received increasing attention over the past few years in higher education. These courses provide appealing opportunities to view classes taught in well-established universities worldwide. The current study aims to examine how OCW lectures can serve as authentic learning materials to facilitate vocabulary acquisition for learners learning English as a foreign language (EFL). It further investigates factors that influence the effectiveness of vocabulary acquisition via OCW lectures. Three open-course lectures from MIT and Yale University, on psychology, physics, and music, were selected. Sixty-five Taiwanese college students participated in the study. The results of pre- and post-testing indicate that learners were able to gain L2 vocabulary knowledge by simply viewing an OCW lecture once. Level of vocabulary (academic vocabulary, technical vocabulary and low-frequency vocabulary) was found to be the most influential factor affecting vocabulary acquisition through OCW lectures. In addition, learners improved more on technical words than on academic ones. Verbal elaboration was also an important factor affecting vocabulary acquisition; the more explicit the elaboration is the greater the vocabulary gain. Frequency of occurrence, on the other hand, had positive but relatively small effects on learners' vocabulary gain. Adapted from the source document

摘要：This study analyzed phonological short-term memory (PSTM) and working memory (WM) and their relationship with vocabulary and grammar learning in an artificial foreign language. Nonword repetition, nonword recognition, and listening span were used as memory measures. Participants learned the singular forms of vocabulary for an artificial foreign language before being exposed to plural forms in sentence contexts. Participants were tested on their ability to induce the grammatical forms and to generalize the forms to novel utterances. Individual differences in final abilities in vocabulary and grammar correlated between 0.44 and 0.76, depending on the measure. Despite these strong associations, the results demonstrated significant independent effects of PSTM and WM on L2 vocabulary learning and on L2 grammar learning, some of which were mediated by vocabulary and some of which were direct effects.

摘要：This study explores different aspects of the mapping between phonological form and meaning of signs in British Sign Language (BSL) by means of four tasks to measure meaning recognition, form recognition, form recall, and meaning recall. The aim was to investigate whether there is a hierarchy of difficulty for these tasks and, therefore, whether BSL vocabulary acquisition proceeds incrementally, as is the case for spoken languages. Twenty-four deaf participants (aged 5-15 years), all of whom were BSL users, performed with greatest accuracy on meaning recognition and least accurately on meaning recall. The results indicate that signers' knowledge of mapping between form and meaning in BSL signs is not an all-or-nothing phenomenon but depends on what the learner is required to do with that knowledge, as is the case for spoken languages.

摘要：Previous research investigating the effects of unassisted and assisted repeated reading has primarily focused on how each approach may contribute to improvement in reading comprehension and fluency. Incidental learning of the form and meaning of unknown or partially known words encountered through assisted and unassisted repeated reading has yet to be examined in an ecologically valid context. This study investigated the effects of assisted and unassisted repeated reading on incidental vocabulary learning with beginner readers over two seven-week periods. A total of 82 students who were 15-16 years old and studying English as a foreign language in Taiwan read or read and listened to 28 short texts several times. To measure the effects of each condition, a modified vocabulary-knowledge scale was used in a pretest and post-test design. The results indicated that both types of repeated reading contributed to vocabulary learning with assisted repeated reading leading to significantly greater vocabulary knowledge. The implications for the development of reading skills and vocabulary size are discussed in detail. Adapted from the source document

摘要：This article reports on the design and use of a profiler for lexical sophistication (i.e., use of advanced vocabulary), which was created to assess the lexical richness of intermediate and advanced Swedish second language (L2) learners' French and Italian. It discusses how teachers' judgments (TJs) of word difficulty can contribute to the methodology for lexical profiling and compares two methods, one purely frequency based and one modified on the basis of TJs of word difficulty. It has been suggested elsewhere that factors other than frequency play an important role in vocabulary acquisition. Here it is argued that cognates and thematic vocabulary related to teaching materials, although infrequent in target language (TL) corpora, should not necessarily be considered advanced and that analyses of learners' lexical sophistication would benefit from integrating these aspects. In this study, the frequency-based method normally used in lexical profiling was modified by recategorizing some low-frequency words considered easy by many teachers. On the basis of the TJs, a basic vocabulary, which consisted mainly of high-frequency words but also of cognates and thematic words, was defined, which was based on the fact that teachers judged certain low-frequency cognates and thematic words as relatively easy. Using the modified method, learners' lexical profiles were found to be more homogeneous within groups of learners at specific proficiency levels. The superiority of the new method over the purely frequency-based one was shown when comparing effect sizes. It is argued that this method gives a more correct picture of advanced L2 lexical profiles. Adapted from the source document

摘要：This article reviews the literature of multimedia glosses in computer assisted language learning (CALL) and their effects on L2 vocabulary acquisition during the past seventeen years. Several studies have touched on this area to examine the potential of multimedia in a CALL environment in aiding L2 vocabulary acquisition. In this review, the researchers investigate the studies that deal with different modes of multimedia annotations in a CALL environment. This article reviews the empirical studies of multimedia glosses in reading as well as in listening comprehension activities and discusses the factors under which these studies have been conducted and their impact on L2 vocabulary acquisition. The study aims to understand how multimedia glosses have been used in the past to support second language vocabulary acquisition and also to explore any evidence regarding how multimedia glosses in a CALL environment can enhance the acquisition of L2 vocabulary. Only empirical studies (18 studies published in international refereed journals and conference) have been reviewed exclusively. The article discusses the findings of the reviewed studies and recommends future research. Adapted from the source document

摘要：Although the Word Associates Format (WAF) is becoming more frequently used as a depth-of-knowledge measure, relatively little validation has been carried out on it. This report of two validation studies tackles various important WAF issues yet to be satisfactorily resolved. Study 1 conducted introspective interviews regarding students' WAF test-taking behavior along with interviews on featured target words to determine how accurately the most common scoring system for the WAF reflects the examinees' actual knowledge of the words. Analysis is provided concerning WAF accuracy and item answering strategies and patterns. Study 2 repeated the interview procedures from Study 1 with several modifications, including the addition of a receptive dimension in the word knowledge interview. The various WAF-scoring methods were compared, and the format types (6 and 8 option), distractor types, and distribution of answers were examined in depth. Both studies indicate that the WAF reflects true lexical knowledge fairly well at the extremes of the scoring scale while scores in the middle do not lead to any reliable interpretation. Furthermore, there is the likelihood that the WAF may both underestimate and overestimate vocabulary knowledge. Suggestions regarding item construction and use of the WAF are given to improve its accuracy and reliability. [Reprinted by permission of Sage Publications, Ltd., copyright holder.]

摘要：This new strand in the journal provides a space for contributors to present a personal stance either on future research needs or on the perceived current applications of research in the classroom. Like much of our current content, it echoes the historical uniqueness of this journal in terms of its rich and expert overview of recent research in the field of L2 teaching and learning. However, this new strand takes such research as its starting point and attempts to look forward, using these findings both to debate their application in the language learning classroom and also to suggest where research would be best directed in the future. Thus, the objective of both types of paper is eminently practical: contributors to the research agenda will present suggestions for what research might usefully be undertaken, given what is currently known or what is perceived to be necessary. In the research into practice papers there will be critical appraisal both of what research is, and is not, getting through to the language learning classroom, policy making, curriculum design, evaluation of teaching and/or assessment programmes, and practical suggestions made for improving such outcomes. This article is a personal view of the application of research on vocabulary to teaching and how there are three different types or categories of relationship between that research and the teaching to which it is applied: first, where the research is not applied or not applied well, second, where it is reasonably well applied, and third, where it is over-applied. For each of these three categories, I look at what I consider to be the most important areas of research and suggest why they fit into that category. The topics covered include planning vocabulary courses, distinguishing high frequency and low frequency words, extensive reading, the deliberate learning of vocabulary, academic vocabulary and vocabulary teaching.

摘要：This article reports on a study on learning new and relearning forgotten words of French as a foreign language in young (mean age 22.4), middle-aged (mean age 50.3), and elderly speakers (mean age 76.0). The three age groups performed similarly on relearning old words, but the younger learners were significantly better at learning new words. Data from a questionnaire on contact with French and a working-memory test showed that neither diminished language contact nor age-related decline in working memory can be seen as single factors explaining differences between learning and relearning. The decline in older adults' ability to learn new lexical information is discussed in terms of theories explaining age-related memory deficits and conceived of as an age-related deficiency to form associations between unrelated concepts.

摘要：This article extends recent findings that presenting semantically related vocabulary simultaneously inhibits learning. It does so by adding story contexts. Participants learned 32 new labels for known concepts from four different semantic categories in stories that were either semantically related (one category per story) or semantically unrelated (four categories per story). They then completed a semantic-categorization task, followed by a stimulus-match verification task in an eye-tracker. Results suggest that there may be a slight learning advantage in the semantically unrelated condition. However, our findings are better interpreted in terms of how learning occurred and how vocabulary was processed afterward. Additionally, our results suggest that contextual support from the stories may have surmounted much of the disadvantage attributed to semantic relatedness.

摘要：Diminutive derivations (e.g., froggy, bootie) constitute morphophonologically similar clusters of words in child-directed speech and serve as low-level schema for learning morphological regularities. Previous research has demonstrated that by regularizing noun endings, diminutives (e.g., Russian:domik,svechka) facilitate word-boundary identification and the acquisition of inflectional morphology. In this study, adult native speakers of English (N= 77) were exposed to diminutive and simplex transparently gender-marked nouns instantiating Russian case-marking and adjective-noun gender-agreement patterns, over six 1-hour language-learning sessions. They were subsequently tested on their ability to extend grammatical patterns to new items and vocabulary recall. Learners showed equivalent learning of the trained phrases containing diminutive and simplex nouns but were more accurate in generalizing morphological patterns to diminutive nouns. Furthermore, learners showed a diminutive advantage in vocabulary retention. By increasing the invariant parts of words, diminutive derivations may reduce the amount of phonological material to be memorized and, subsequently, enhance word learning.

摘要：This study investigates outcomes of deliberate learning on vocabulary acquisition in a second language (L2). Acquisition of 48 pseudowords was measured using the lexical decision task with visually presented stimuli. The experiments drew on form priming, masked repetition priming, and automatic semantic priming procedures. Data analyses revealed a prime lexicality effect (Experiment 1), repetition priming effect (Experiment 2), and semantic priming effect (Experiment 3) for the deliberately learned pseudowords. The outcomes of deliberate learning were further examined using a coefficient of variability (CVRT) calculated for the participants' response latencies in Experiments 2 and 3. The results showed that the learned pseudowords were processed with a higher degree of automaticity than nonwords and low-frequency L2 words. Taken together, the findings provide evidence that deliberate learning triggered the acquisition of representational and functional aspects of vocabulary knowledge.

摘要：This study compared negative and positive evidence in adult word learning, predicting that adults would learn more forms following negative evidence. Ninety-two native English speakers (32 men and 60 women [M age = 20.38 years, SD = 2.80]), learned nonsense nouns and verbs provided within English frames. Later, participants produced plural and past tense forms for the irregular nouns and verbs following negative or positive evidence. As anticipated, correct production followed negative evidence, and errors followed positive evidence. Additionally, participants learned more verbs than nouns. Implications for first and second language learning are discussed.

摘要：A limitation of extensive reading programmes is the time required for progress in vocabulary acquisition. This paper reports on a qualitative exploration of student perceptions of the value of non-compulsory comic books in ESL elementary and upper-intermediate level courses at a tertiary institution. We aimed to develop supplementary materials that students would find valuable, use, and enjoy without requiring classroom time. The results suggest the learners' views on the value of comic books and recordings can be broadly categorized into five themes: (1) helpful story characteristics, (2) perceived performance enhancement, (3) use of learning strategies, (4) enjoyment, and (5) areas for improvement. An interesting finding was the variety of uses to which the learners put the resources, in particular sharing them with their families. This study points to the importance of responding to learners' specific contexts and to creative ways English learners undertake autonomous learning when provided with appropriate resources.
