The inadequacy of individual educational program (IEP) goals for high school students with word-level reading difficulties     

Catone WV  Brady SA 《Annals of dyslexia》2005,55(1):53-78

This investigation analyzed goals from the Individual Educational Programs (IEPs) of 54 high school students with diagnosed reading disabilities in basic skills (decoding and/or word identification). Results showed that for 73% of the students, the IEPs written when they were in high school failed to specify any objectives regarding their acute difficulties with basic skills. IEPs from earlier points in the students’ educations were also reviewed, as available. For 23 of the students, IEPs were present in the students’ files for three time points: elementary school (ES), middle school (MS), and high school (HS). Another 20 students from the sample of 54 had IEPs available for two time points (HS and either MS or ES). Comparisons with the IEPs from younger years showed a pattern of decline from ES to MS to HS in the percentage of IEPs that commented on or set goals pertaining to weaknesses in decoding. These findings suggest that basic skills deficits that persist into the upper grade levels are not being sufficiently targeted for remediation, and help explain why older students frequently fail to resolve their reading problems.  相似文献   

Invented spelling: what is the best way to improve literacy skills in kindergarten?     

Loïc Pulido  Marie-France Morin 《教育心理学》2018,38(8):980-996

Abstract

We examined the progress made by 132 six-year-old French-speaking children in their preliteracy skills during four kinds of interventions. Three of these interventions concerned invented spelling, where the children tried to spell words. In the first condition, they were encouraged to reflect on conventional spellings. In the second condition, they reflected on spellings that were slightly more complex than theirs, while in the third condition, they reflected on increasingly complex spellings that eventually led to the conventional spellings. The fourth condition (control) consisted of phonological training. We assessed the children’s phonological awareness, letter knowledge, spelling, and decoding skills, controlling for vocabulary and nonverbal cognitive ability. Posttest results indicated progress in each condition. The greatest progress was observed in the second condition for decoding, spelling, letter-name knowledge and syllable awareness, and in the control condition for phoneme awareness. Overall, results showed that all kinds of interventions led to very similar levels of progress, but that improvements were greater for interventions that focused on the children’s initial invented spellings - in other words, when they adopted a Vygotskian perspective.  相似文献

并列结构组成成分排序原则及原因初探     

张彦群  辛长顺 《天中学刊》2002,17(4):69-73

并列结构语序从纯语法上说其关系至关重要，是自由灵活的，但如果从语义和语用的角度看，又是相对固定的，排序时要受到多种原则的制约。汉语并列结构组成成分排序大致遵循如下原则：时空原则、感知原则、文化原则、语音原则、逻辑原则、语境原则、语言习惯等。这些排序原则是以认知心理、社会文化、语音特征、逻辑事理、约定俗成等多种因素为基础而形成的。  相似文献   

培智学校语文教材拼音、生字分析--以上海教育出版社出版的第八册实用语文教材为例     

张燕 《毕节学院学报》2016,(5):84-88

教材作为教学的重要媒介,必然会影响学生的学习效果;教材编写的合理性值得大家思考。拼音、生字是智障儿童语文学习的基础,也是智障儿童教育的一项重要且困难的任务。上海教育出版社出版的第八册实用语文教材在拼音、生字两方面都存在一定的问题,在培智学校语文教材的拼音编写方面建议从识字起步,拼音放后,重在积累,按照智障学生掌握语音的规律编写拼音;在生字编写方面建议按智障学生掌握语音的规律编写生字,坚持“识写分离”的原则编排生字,按智障儿童获得生字的词性、结构规律编排生字。  相似文献   

Spoken vocabulary growth: Its role in the development of phoneme awareness and early reading ability     

Walley  Amanda C.  Metsala  Jamie L.  Garlock  Victoria M. 《Reading and writing》2003,16(1-2):5-20

In this paper, two theoretical positionsregarding the developmental origins of thephoneme as a unit for lexical representationand processing are outlined – theaccessibility and emergent positions. OurLexical Restructuring Model (Metsala & Walley1998), which is consistent with the secondposition, focuses on the role of vocabularygrowth in prompting the implementation of morefine-grained, segmental representations forlexical items in childhood; this restructuringis viewed as an important precursor to theexplicit segmentation or phoneme awarenessskills implicated in early reading success.Empirical evidence that supports this model issummarized, including preliminary results fromone of our most recent studies. Severalsuggestions are made for future research thatwill lead to a better understanding of thedevelopment of spoken word recognition and thelinks between speech- and reading-relatedabilities.  相似文献   

Pattern design on 3D triangular garment surfaces     

WANG Jin LU Guo-dong LI Ji-tuo CHEN Long ZHANG Dong-liang 《浙江大学学报(A卷英文版)》2007,8(10):1642-1649

This paper focuses on a pattern design method for a 3D triangular garment surface. Firstly, some definitions of 3D style lines are proposed for designing the boundaries of patterns as drawing straight lines or splines on the triangular surface. Additionally some commonly used style lines are automatically generated to enhance design efficiency. Secondly, after style lines are preprocessed, a searching method is presented for quickly obtaining the boundaries and patches of a pattern on the 3D trian- gular surface. Finally a new pattern design reuse method is introduced by encoding/decoding the style line information. After style lines are encoded, the pattern design information can be saved in a pattern template and when decoding this template on a new garment surface, it automates the pattern generation for made-to-measure apparel products.  相似文献   

Unsupervised word sense disambiguation for Korean through the acyclic weighted digraph using corpus and dictionary     

Yeohoon Yoon  Choong-Nyoung Seon  Songwook Lee  Jungyun Seo 《Information processing & management》2006

Word sense disambiguation (WSD) is meant to assign the most appropriate sense to a polysemous word according to its context. We present a method for automatic WSD using only two resources: a raw text corpus and a machine-readable dictionary (MRD). The system learns the similarity matrix between word pairs from the unlabeled corpus, and it uses the vector representations of sense definitions from MRD, which are derived based on the similarity matrix. In order to disambiguate all occurrences of polysemous words in a sentence, the system separately constructs the acyclic weighted digraph (AWD) for every occurrence of polysemous words in a sentence. The AWD is structured based on consideration of the senses of context words which occur with a target word in a sentence. After building the AWD per each polysemous word, we can search the optimal path of the AWD using the Viterbi algorithm. We assign the most appropriate sense to the target word in sentences with the sense on the optimal path in the AWD. By experiments, our system shows 76.4% accuracy for the semantically ambiguous Korean words.  相似文献   

Unique-order interpolative coding for fast querying and space-efficient indexing in information retrieval systems     

Cher-Sheng Cheng  Jean Jyh-Jiun Shann  Chung-Ping Chung 《Information processing & management》2006

This paper presents a size reduction method for the inverted file, the most suitable indexing structure for an information retrieval system (IRS). We notice that in an inverted file the document identifiers for a given word are usually clustered. While this clustering property can be used in reducing the size of the inverted file, good compression as well as fast decompression must both be available. In this paper, we present a method that can facilitate coding and decoding processes for interpolative coding using recursion elimination and loop unwinding. We call this method the unique-order interpolative coding. It can calculate the lower and upper bounds of every document identifier for a binary code without using a recursive process, hence the decompression time can be greatly reduced. Moreover, it also can exploit document identifier clustering to compress the inverted file efficiently. Compared with the other well-known compression methods, our method provides fast decoding speed and excellent compression. This method can also be used to support a self-indexing strategy. Therefore our research work in this paper provides a feasible way to build a fast and space-economical IRS.  相似文献
