This paper investigates the role of definitional information versus contextual information in computer‐assisted vocabulary instruction. A group of 58 advanced ESL students participated in the main data‐collection phase. The results revealed that context‐embedded vocabulary exercises facilitate better long‐term retention of words that exist in context. This finding is noteworthy in that the context‐embedded condition is the natural vocabulary condition commonly observed in reading. Students seldom encounter direct definitions or a series of related synonyms in the natural passage condition. Definitional knowledge, however, appears to be important in developing a basic concept of a given word in the initial phases of vocabulary development.  相似文献

The purpose of this study was to examine the effectiveness of a vocabulary intervention designed to supplement research‐based classroom vocabulary instruction, implemented with students who may be at risk for language and learning difficulties. Participants included 43 kindergarten students who received research‐based classroom vocabulary instruction. Students with the 20 lowest scores on the Peabody Picture Vocabulary Test‐III administered at pretest received additional small‐group supplemental vocabulary intervention. Results of within‐subjects comparisons indicated that, overall, at‐risk students made greater gains in word knowledge on target words that received the supplemental intervention as compared to words that received only classroom‐based instruction. In addition, at‐risk students who received the supplemental intervention demonstrated word‐learning gains that approached those of their peers who received classroom instruction alone. Implications along with limitations of the current study and directions for future research are discussed.  相似文献

ABSTRACT

The way computers are used in foreign language teaching reflects teachers' ideas about how foreign languages should be learned. We describe different methods of foreign language teaching, one of which is at the base of our computer program IT'S English. In this program, different types of exercises are implemented: receptive, reproductive, and productive. To implement our ideas of a communicative approach to teaching into a computer program, we built an intelligent tutoring system, which incorporates a dictionary, grammar rules, and the digitized pronunciation of words and sentences stored on a CD‐ROM. The software is flexible in that the learning environment it offers can shift from a teacher controlled setting to a fully learner controlled environment. Four groups of eight pupils used the program during eight weeks and were compared with students not using the program. The research showed that the students interacting with the software used its various components in an adequate and goal‐appropriate way and found the use of the software to be a positive experience. After the experimental period, knowledge of vocabulary was significantly higher for one of the computer‐using groups compared to its control group, although in the word (re)production tests no significant differences were found between the experimental and control groups. Implications of the results of the experiments for teacher education are discussed, with an emphasis on the importance of teachers learning how to assess the pedagogical approach of software and the didactic principles involved in its design and intended use.  相似文献

We examined the effects of adaptive word retrieval intervention on a classroom vocabulary program on children’s vocabulary acquisition in kindergarten. In the experimental condition, word retrieval was provided in a classroom vocabulary program, combining implicit and explicit vocabulary instructions. Children performed extra word retrieval activities and received semantic feedback for words they did not learn during the classroom vocabulary program. Eighty-seven children were in the experimental condition, and 115 children were in the classroom vocabulary control condition. Results showed the adaptive word retrieval intervention to stimulate higher learning gains than the classroom vocabulary program on the learning of the target words. Children in the experimental condition also showed transfer effects; they described more words on a standardized expressive vocabulary test than children in the control condition. The research findings suggest additional value of word retrieval with feedback for classroom vocabulary learning.  相似文献

There is reliable evidence that new vocabulary is primarily acquired through wide independent reading. However, struggling readers tend to avoid reading, resulting in limited word encounters and inadequate vocabulary growth, and they often have difficulties inferring the meanings of new words from context. While there are no clear solutions to the problem of vocabulary acquisition for older students with reading difficulties, there are instructional approaches that have some evidence of effectiveness for this population. We describe the research base and promising practices related to three aspects of vocabulary instruction: (1) creating a verbal learning environment that fosters word consciousness, (2) selecting and teaching specific words, and (3) teaching an independent word learning strategy through a combination of contextual and morphemic analysis. These instructional approaches are grounded in overarching principles recognized by researchers as being characteristic of effective instruction for students with learning difficulties, including explicit instruction, promoting cognitive and collaborative engagement, and providing many opportunities for practice, including distributed practice, with teacher feedback. Finally, we discuss the possibilities inherent in a cross‐content schoolwide approach to vocabulary instruction at the secondary level. We conclude with a call for additional research examining the effectiveness of instructional approaches to vocabulary development for secondary school students with reading difficulties, including a schoolwide collaborative model.  相似文献

Abstract

The purpose of this study was to investigate the efficacy of an 18-week program of direct and extended vocabulary instruction with kindergarten students on both proximal measures of target word knowledge and transfer measures of generalized language and literacy. A second purpose was to examine whether treatment effects would be moderated by initial receptive vocabulary knowledge measured at pretest. In a quasi-experimental design, 80 kindergarten students from schools serving large at-risk populations were taught the meanings of 54 vocabulary words within interactive story read alouds over 36 half-hour instructional lessons (2 lessons per week over 18 weeks). An additional 44 students served as a no-treatment control. Findings indicated that students who received vocabulary instruction outperformed controls on a measure of target word knowledge as well as measures of generalized receptive vocabulary and listening comprehension. In addition, initial receptive vocabulary was strongly related to posttest performance on all measures. Implications are discussed in relation to supporting vocabulary development in the early grades within a multitier framework of instruction and intervention.  相似文献

An experiment with random assignment examined the effectiveness of a strategy to learn unfamiliar English vocabulary words during text reading. Lower socioeconomic status, language minority fifth graders (M?=?10?years, 7?months; n?=?62) silently read eight passages each focused on an unknown multi-syllabic word that was underlined, embedded in a meaningful context, defined, depicted, and repeated three times. Students were grouped by word reading ability, matched into pairs, and randomly assigned to one of two conditions. In the strategy condition, students orally pronounced the underlined words during silent reading. In the control condition, students penciled a check if they had seen the underlined words before but did not say the words aloud. Results of ANOVAs showed that the oral strategy enhanced vocabulary learning (ps?<?.01), with poorer readers showing bigger effect sizes than better readers in remembering pronunciation-meaning associations and spellings of the words. In a second experiment, 32 fifth graders from the same school described the strategies they use when encountering unfamiliar words in context. Better readers reported more word-level strategies whereas poorer readers reported more text-based strategies. Our explanation is that application of the word-level strategy of decoding new words aloud strengthened connections between spellings, pronunciations, and meanings in memory compared to silent reading of new words, particularly among poor readers who were less skilled and less likely to use this strategy unless instructed to do so.  相似文献

Deficits in vocabulary have a negative impact on literacy and interpersonal interaction for deaf children. As part of an evaluation, an outcomes assessment was conducted to determine the effectiveness of a computer-based vocabulary tutor in an elementary auditory/oral program. Participants were 19 children, 16 profoundly deaf and 3 hearing. The vocabulary tutor displays line drawings or photographs of the words to be learned while a computer-generated avatar of a "talking head" provides synthesized audiovisual speech driven from text. The computer system also generates printed words corresponding to the imaged items. Through audiovisual reception, children memorized up to 218 new words for everyday household items. After 4 weeks, their receptive vocabulary was tested, using the avatar to speak the name of each item. Most of the students retained more than half of the new words. The freely available vocabulary tutor, whose characteristics can be tailored to individual need, can provide a language-intensive, independent learning environment to supplement classroom teaching in content areas.  相似文献

Abstract

This study was designed to assess whether knowing the meaning of a word facilitates one’s ability to spell it. A total of 180 fourth, sixth, and eighth graders took four spelling tests and four multiple-choice vocabulary tests on a list of 100 words. Results of analysis showed that when the effects of word frequency, word length, and phoneme-grapheme regularity were partialed out, there was still a significant relationship between ability to spell words and understanding of their meanings. Implications for the teaching of spelling and vocabulary are discussed.  相似文献

ABSTRACT

This study took place in a school which adopted a “paperless classroom” policy. The purpose of the study was to examine whether students who learn in a paperless classroom really prefer reading and writing on computers rather than on paper and whether their preferences differ according to contextual conditions and personal differences. The findings show that students’ reading and writing preferences depended on the context in which the reading or writing was performed. The boys preferred to read and write on the computer significantly more than girls. Conversely, the girls’ handwriting skills and preference for handwriting were higher than the boys’. Reading and writing on computer was found to be favored among strong students, while weak students tended to prefer using paper. This research also revealed a rapid decrease in favoring computer over paper in both reading and writing over time. Students who had experienced the paperless classroom policy in this school for three years were less supportive of the use of computers for reading and writing than younger students.  相似文献

The purpose of this study was to investigate the impact of imagery interventions on the vocabulary acquisition abilities of second grade students. A total of 15 students were randomly assigned to three different intervention conditions: Word Only, which involves the simple verbal presentation of a vocabulary word; Dual Coding, in which a picture was paired with the vocabulary word, and Image Creation, in which students were told to create a mental picture of the vocabulary word in their mind and draw it on paper. These students were taught a total of 21 vocabulary words: seven animal and habitat words, seven musical instrument terms, and seven science terms. A Latin square design was used, in which each group of students rotated through each of the interventions, being exposed to a different treatment condition for each category of words. Participants were measured on the number of words they were successfully able to acquire through the use of experimenter designed comprehension measures. While no statistical significance was shown between the interventions across the word categories, a significant difference was found between the Image Creation and Word Only interventions within the science terms category. Students also reported that the imagery interventions facilitated the ease with which they learned the words. The findings have implications for increasing the success of classroom instruction, specifically for presenting novel vocabulary words to early elementary learners using imagery methods.  相似文献

文章结合维特根斯坦的语义整体论,从语词的意义这一语言哲学的基本问题的角度,探讨其对外语教学中的词汇教学的启发。在对维特根斯坦后期语义整体论的两个主要概念:即语言游戏说和意义使用说的分析基础上,文章认为整体论对外语词汇教学的启示有两方面:第一,词汇的习得与语词意义的理解有着密切的关系,而词义的理解在于对词汇的使用;第二,词义的理解离不开相应的语境,因此语境知识的补充是提高词汇习得水平的有效方法之一。  相似文献

The purpose of this study was to examine whether English language learners (ELLs) would increase their vocabulary scores in the areas of word recognition, word meaning, and word application when iPads were used during vocabulary instruction. Five third-grade ELLs, at risk of being diagnosed as having learning disabilities, participated in the study. All students demonstrated low test scores in learning vocabulary words during the baseline. During the intervention, 36 vocabulary words selected from the third-grade’s Dolch word list were taught and practiced using the iPad application Learning Touch, First Sight Words Pro. All students were assessed and their vocabulary scores increased in the areas of word recognition, word meaning, and word application. Using the iPad and iPad app appears to provide a potential avenue for ELLs in learning English vocabulary words.  相似文献

One important purpose of a definition is to explain the meaning of a word. Any problems associated with a definition may impede students' learning. However, research studies on the definitional problems from the perspective of physics education are limited. Physics educators may not be aware of the nature and extent of definitional problems. As an example, The Feynman Lectures of Physics suggest that there are at least four problems of definition: precision, circularity, context and completeness in knowledge. Feynman had the tendency of mentioning the words ‘define’ and ‘definition’ and discussing the problems of definition: they can be insightful, or challenge the conventional, preconceived notions of many physical concepts. One benefit of this study is that a framework can be developed to improve statements of definitions. This framework may guide educators or students to analyze the knowledge that is embedded in a definition. In the future, the learning of definition need not be content-oriented, but problem-based instead, with the help of definitional problems. Therefore, the use of these problems of definition in lessons can be an interesting area for future physics education research. Furthermore, we should be cognizant of inadequacies or inaccuracies in definition that may result in alternative conceptions.  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

In 2 studies, we compared the effectiveness of 4 different methods for acquiring initial reading vocabulary. Training emphasized similarity of word beginnings (onset plus vowel), similarity of word endings (rimes), phoneme segmentation and blending, or simple repetition of whole words. These 4 training regimes were compared with a control group given only regular classroom instruction. Beginning nonreaders acquired the trained words fastest in the onset and rime conditions, and most slowly in the whole word condition. Retention was excellent after 1 week and after 4 to 6 months, with no differences due to method of acquisition when only children who met the learning criterion were considered. Generalization to reading new words and nonwords was 40% to 50% on the first encounter for all children who acquired the entire word set during learning. In Experiment 2, the same pattern of results was obtained for delayed readers in Grade 2.  相似文献

The purpose of this article is to share one middle school's approach to using content area word walls in the classroom, as well as in the hall, to enhance the comprehension and retention of content area vocabulary. Eighth grade teachers and students designed and maintained classroom content word walls, as well as an interactive multi-content word wall in the eighth grade hall. It visually displayed the vocabulary aligned with the eighth grade state curriculum and the annual state assessment. State assessment scores showed an increase in the area of reading, math, and science after students and teachers engaged in these two types of word walls.  相似文献
