The goal of this experimental intervention study was to determine if evidence-based instructional strategies for general vocabulary words are effective with middle school English learner (EL) students and academic vocabulary words. Participants showed significantly more growth in their knowledge of academic vocabulary during the treatment condition than during the control condition. A secondary goal of this study was to examine the predictive utility of students’ English language proficiency, and students’ general vocabulary knowledge in English was a positive predictor for their academic vocabulary growth during the intervention. However, participants’ growth during the control period had the greatest predictive utility for their growth during the intervention. Furthermore, this relationship was negative, suggesting that the intervention had the greatest benefits for students who made the least progress in English vocabulary in the absence of the intervention. Implications for instruction, policy, and future research are presented.  相似文献

This study looks into the reading practice in a Grade 4 knowledge building community that involved 22 students and a veteran teacher. The students investigated light over a three-month period supported by Knowledge Forum, a networked collaborative knowledge-building environment. The classroom designs encouraged the students to take on high-level responsibility for advancing the community’s knowledge, as represented in their online discourse in Knowledge Forum. The tracing of student conversations in Knowledge Forum and content analysis of their portfolio notes demonstrate productive advancement of scientific understanding. Qualitative analyses of classroom videos, online discourse, and the teacher’s reflection journal characterize student reading practice along four themes: reading for the purpose of advancing community knowledge; as progressive problem solving; embedded in sustained knowledge-building discourse; and as dialogues between local understanding and knowledge in the larger world. These results contribute to elaborating the possibility and processes of integrating reading with creative knowledge work in content areas. Classroom strategies are identified and discussed in relation to the role of collaborative online technologies.  相似文献

中国非英语专业研究生词汇量不同词频等级分布状况研究   总被引:1,自引:0,他引:1  
本文探讨了中国非英语专业研究生的接受性和产出性词汇量在高频、中频、低频以及学术类词汇四个词频等级的分布情况。上海市两所重点高校的360名研究生参加了两种分别测量学习者接受性和产出性词汇的词汇测试。研究结果表明,我国非英语专业研究生能够掌握大多数高频词和学术类词汇的基本含义,但由于他们对中低频词,尤其是低频词的认知率较低,在今后的学习中仍有可能面临词汇上的困难;研究生的产出性词汇量要远低于其接受性词汇量,且大部分产出性词汇仍属于高频词;尽管学生对学术类词汇的认知率较高,但他们在该词频上的产出性词汇量仍有待进一步提高。针对上述结果,研究建议在研究生英语教学过程中教师应注意对学生词汇学习策略的培养,并通过数据驱动学习、转变写作任务模式等途径扩大学生的产出性词汇量。  相似文献

This study reports on the development of an assessment to measure bilingual adolescents’ knowledge of polysemous vocabulary and explores the contribution of polysemous word knowledge to reading comprehension among those students. Spanish–English bilingual students in seventh grade (n = 107) completed a battery of standardized reading and language measures along with a researcher-designed measure of their knowledge of the academic senses of words that also have casual, everyday meanings. Item-response theory analyses and correlational analyses provided validity evidence for the assessment. Regression analyses indicated that students’ knowledge of academic senses of polysemous words predicted their reading comprehension, even after controlling for their knowledge of the casual sense of the same words, vocabulary breadth, and decoding skills. Findings suggest that comprehension of grade-level texts is uniquely predicted by the ability to recognize the meanings of familiar words when they appear in academic contexts.  相似文献

This study investigated the effects of engaging students to collectively learn and work with knowledge in a computer-supported collaborative learning environment called Knowledge Forum on their views about knowledge building theory and practice. Participants were 24 teacher-education students who took a required course titled “Integrating Theory and Practice in Teaching.” Data mainly came from (1) student discourse recorded in a Knowledge Forum database, (2) a survey that examined students’ views about knowledge building, and (3) interviews with regard to students’ perceived barriers to implementing knowledge building theory in teaching. Findings suggest that with sustained discourse to construct their collective understanding of the relationships between theory and practice in teaching for a semester, the participants were able to attain more informed and practical views about knowledge building theory. In addition, students’ perceived barriers to implementing knowledge building in teaching were identified and strategies to help overcome these barriers discussed.  相似文献

To a science ‘outsider’, science language often appears unnecessarily technical and dense. However, scientific language is typically used with the goal of being concise and precise, which allows those who regularly participate in scientific discourse communities to learn from each other and build upon existing scientific knowledge. One essential component of science language is the academic vocabulary that characterises it. This mixed-methods study investigates middle school students’ (N?=?59) growth in academic vocabulary as it relates to their teacher’s instructional practices that supported academic language development. Students made significant gains in their production of general academic words, t(57)?=?2.32, p?=?.024 and of discipline-specific science words, t(57)?=?3.01, p?=?.004 in science writing. Results from the qualitative strand of this inquiry contextualised the students’ learning of academic vocabulary as it relates to their teacher’s instructional practices and intentions as well as the students’ perceptions of their learning environment. These qualitative findings reveal that both the students and their teacher articulated that the teacher’s intentional use of resources supported students’ academic vocabulary growth. Implications for research and instruction with science language are shared.  相似文献

This quasi-experimental study investigated the effects of an Internet-delivered universally designed depth of vocabulary intervention that targeted both English-speaking and Spanish–English-speaking students. Two hundred forty students, 49% of whom were Spanish–English bilinguals, participated in the 16-week intervention. Intervention students read eight multimedia texts with embedded instruction on 40 words and reading strategy support. Students could access all texts and activities in Spanish and English. In comparison to a control group, there were significant intervention effects on a standardized measure of vocabulary knowledge, but effects were non-significant for comprehension. Similarly, significant effects on researcher-developed measures of vocabulary depth were detected, but not for a researcher-developed measure of breadth.  相似文献

Previous research has documented the role of readers’ existing topic knowledge in supporting students’ comprehension of text; yet, we know less about how to build students’ knowledge in order to support comprehension and vocabulary learning. In the current study, we test the hypothesis that knowledge can be built and leveraged simultaneously in the interest of students’ literacy development through the use of conceptually coherent text sets. Fourth grade students (N = 59) were randomly assigned to read either a set of six informational texts that cohered around a set of concepts related to the topic birds (CC texts) or a set of texts that addressed a range of topics (NCC group texts). After reading, we assessed students’: (1) knowledge of the concepts in the conceptually coherent text set, (2) knowledge of target concept-related words that appeared in their respective text sets, (3) knowledge of general academic words that appeared in both texts sets, (4) comprehension of a novel text on a related topic, and (5) interest in the topic of the conceptually coherent texts. Results revealed that students who read the conceptually coherent texts demonstrated more knowledge of the concepts in their texts, more knowledge of the target words in their texts, and had better recall of the novel text compared to students who read unrelated texts. Findings suggest that there is potential for knowledge and vocabulary to be built during English language arts through a focus on conceptual coherence in the design of reading experiences for students.  相似文献

本文讨论了当前中学英语词汇教学中普遍存在的问题, 即过分强调学生死记硬背单词的读音、词形和字典意义, 而忽略了词汇的搭配、用法、实际含义和语法特征,忽略了语境在词汇学习中的重要性, 导致学生对许多单词只会记而不会用, 一用就错漏百出, 给英语学习造成障碍, 也给考试质量带来很大的负面影响。词汇关是英语学习中最关键的一关, 而这种强调死记硬背的词汇教学方法使许多学生对英语单词望而生畏, 因此解决这一问题可以说是英语教学需要突破的瓶颈。作者通过分析产生这一问题的原因, 引述国内外有关英语词汇教学的理论著作, 结合我国学生急于求成、词汇运用能力低下和缺乏学习兴趣的现象, 提出教师首先要充分利用常规课堂教学的阵地,帮助学生掌握基本词汇的用法和自主学习的技巧, 如猜词、查词典、词义联想等策略, 通过课堂活动、校园英语角、英语晚会等, 让学生拥有学习和运用英语的基本能力,并引导学生结合自己的兴趣, 多渠道增加阅读量和泛听量, 如听英文歌曲和英语新闻、看英语电影和电视节目、读简易读物等, 使学生通过多听、多说、多读、多写和多练来习得词汇。  相似文献

This study employed group randomized trials to investigate the effects of self‐ and peer‐monitoring on the academic vocabulary and content knowledge of students with learning disabilities and low achieving students in social studies. Fourth grade students were randomly assigned to either treatment or control groups on a class level. Results indicated that there was a significant interaction effect between the intervention and students’ pretest scores on academic vocabulary acquisition; the intervention was more effective for students with lower scores in the pretest than those with higher scores. In addition, there was a significant intervention effect on content knowledge acquisition; the effect size of the growth of the treatment group on the content knowledge test was significantly larger than that of the comparison group. Teacher interviews also revealed that teachers viewed the intervention positively. Implications for practice and suggestions for future research are discussed.  相似文献

Understanding academic vocabulary is essential to student success in school. Use of academic vocabulary words in writing is considered one of the strongest measures of how well a reader understands a given word. In theory, willingness to use academic vocabulary in writing indicates the complexity of acquiring representations of the word’s orthography, phonology, and semantics based on the word’s characteristics. In addition, a learner’s overall literacy skills should relate to whether they attempt to use words. In the present study, sixth graders (n = 66), seventh graders (n = 60), and eighth graders (n = 41) learned 25 academic vocabulary words in a supplementary academic vocabulary intervention and were then asked to use those words in short persuasive essay drafts. We measured whether these students attempted to use a word (a binary uses outcome) and the number of times a student used a word (a continuous attempts outcome) and used cross-classified random effects models to examine how (a) the orthographic, phonological, and semantic characteristics of words and (b) the students’ literacy-related characteristics related to their uses and attempts. For word characteristics, students were more likely to use and attempt high frequency than low frequency words. For student characteristics, students proficient on the state exam were more likely to use and attempt the words, and students learning English were less likely to attempt the words. Implications for vocabulary intervention and writing instruction are discussed.  相似文献

Building a text is a multidimensional endeavor. Writers must work simultaneously on the content of the text, its discursive organization, the structure of the sentences, and the individual words themselves. Knowledge of vocabulary is central to this endeavor. This study intends (1) to trace the development of writer’s vocabulary depth, their vocabulary fluency in writing, and the features of the text they produce (productivity, lexical richness, and text structure) through elementary school and (2) to determine the contribution of the writer’s performance and the text features to the quality of the text. One hundred and eighty bilingual Spanish/Catalan speakers from first, third, and sixth grade took part in the study. They participated in three researcher-created tasks; a synonyms/antonyms task to orally assess vocabulary depth; a semantic orthographic fluency task to examine their vocabulary fluency in writing; and a text writing task to evaluate text quality. Data was analyzed using structural equation modeling in order to examine the relationship between the target writer’s performance and the text features of the written compositions, and the externally evaluated text quality. Results revealed that both writer’s performance on vocabulary depth and semantic orthographic fluency and text features improved with school level. However, the capacity to establish meaning relations between words contributed more directly to the quality of texts than the speed to find words with a specific phonographic correspondence. External evaluation of text quality was more variable for younger students than for older students and was affected by school level mediated by writer performance and text features.  相似文献

In an effort to improve student achievement at an urban high school, teachers and administrators developed a 5-part, schoolwide vocabulary plan. Over 4 years, teachers provided students with increased opportunities to read, read to their students, developed content-specific vocabulary instruction, taught students academic words, and focused on 5 words each week with a common prefix, suffix, or root. Over the 4 years, student achievement in vocabulary and reading comprehension improved in significant ways, both on reading assessments and state achievement tests.  相似文献

We tested whether urban middle-school students from mostly low-income homes had improved academic vocabulary when they participated in a freely available vocabulary program, Word Generation (WG). To understand how this program may support students at risk for long-term reading difficulty, we examined treatment interactions with baseline achievement on a state standardized test and also differential effects for students with (n = 398) and without (n = 1,395) individualized education plans (IEPs). Students in this unmatched quasi-experiment (5 WG and 4 comparison schools) completed pre- and postvocabulary assessments during the intervention year. We also retested student vocabulary knowledge after summer vacation and the following spring on 11 target words to construct a longitudinally consistent scaled score across 4 waves of data. Growth models show that students experienced summer setback. Although there were no average underlying differences in growth or differences in summer setback for students by baseline achievement, better readers improved more from program participation. IEP status did not predict differential benefits of program participation, and students with IEPs maintained gains associated with participation in WG; however, participation in the program did not change underlying growth trajectories favoring students who did not have IEPs.  相似文献

The purpose of this study was to investigate prospective mathematics teachers’ knowledge of common conceptions and misconceptions that sixth and seventh grade students had about multiplication of fractions. In addition, prospective teachers’ knowledge of the sources of these misconceptions and strategies they knew to overcome these misconceptions was examined. Data were collected from 17 Turkish prospective teachers at the end of the spring semester of the 2004–2005 academic year. A case study design was used in which data were collected through the Multiplication of Fractions Questionnaire and semi-structured interviews. The prospective teachers suggested many difficulties that elementary grade level students may have and stated that these difficulties stemmed from students’ lack of formal knowledge and rote memorization of the algorithms. In addition, the prospective teachers suggested many strategies that could be used to overcome these misconceptions or difficulties. These strategies could be grouped under three headings: strategies based on teaching methods, strategies based on formal knowledge of fractions, and strategies based on psychological constructs.  相似文献

We investigated general vocabulary and academic vocabulary growth trajectories of adolescent language minority students using an individual growth modeling approach. Our analytical sample included 3161 sixth- to eighth-grade students from an urban school district in California. The language minority students in our sample were classified as initially fluent English proficient (IFEP), redesignated fluent English proficient (RFEP), or limited English proficient (LEP) students. The analytical sample was not a nationally representative sample and included a great number of Asian students and students who receive gifted and talented education. Students were assessed at four time points on a standardized measure of general vocabulary and a researcher-developed academic vocabulary test. On both vocabulary measures, IFEP students slightly outperformed English-only (EO) students on average, and EO students scored higher than RFEP and LEP students at baseline. RFEP and LEP students showed slower rate of growth than their EO peers in general vocabulary. While both EO and language minority students showed summer setback with general vocabulary knowledge on average, the magnitude of summer setback was not as great for LEP students. In academic vocabulary, all subgroups of language minority students showed more rapid rate of growth than their EO peers. Only the REP students experienced a change in the learning trajectory during the summer months. We discuss the implications of these findings for all language groups.  相似文献

The effects of adult questioning on children’s novel word acquisition during storybook reading were investigated. Three-year-olds were assigned to one of three conditions: vocabulary eliciting questions, noneliciting questions, and no questions (control). General vocabulary comprehension and novel word knowledge were equivalent across the groups before the storybook reading intervention. Children were read 3 storybooks repeatedly across 4 reading sessions and were tested for production and comprehension of novel words in the final session. Children’s novel word comprehension increased more in both question conditions than in the control condition, suggesting that type of question is not as important to word learning as children’s active engagement in discussion about novel words in general. Novel word production was not strongly affected by any of the reading conditions. However, asking children noneliciting questions did appear to foster production of new words more than not asking questions at all.  相似文献

This study examined the ability to infer the meaning of novel made-up words that appeared in 16 short narrative texts, presented in two modalities—reading and listening. Hebrew-speaking 4th grade students (N = 54) were asked to infer the meanings of the made-up words in both modality conditions. In this cross-group design, students were randomly assigned to one of two order conditions: reading first or listening first. Regardless of condition, participants were better able to infer the meaning of the made-up words in the listening condition than in the reading condition. Individual differences in word reading, vocabulary, and reading comprehension mediated novel word learning but working memory did not. Results are discussed in relation to the challenges faced by 4th grade Hebrew readers in the transition from reading a fully pointed (vowelized) shallow orthography to an unpointed, deep orthography. The ability of 4th grade readers to infer novel words appears to be enhanced when listening to animated narration, and is mediated by extant vocabulary knowledge and higher-order comprehension processes, but also by basic decoding skills.  相似文献
