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   

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   

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

Competing priorities: Singaporean teachers’ perspectives on critical literacy     

Xiao Lan Curdt-Christiansen 《International Journal of Educational Research》2010,49(6):184-194

This paper explores a group of Singaporean English language teachers’ knowledge and beliefs about critical literacy as well as their perspectives on how best to teach literacy and critical literacy in Singapore schools. A face-to-face survey was conducted among 58 English language teachers by using open-ended questions. The survey covered various topics related to literacy instruction including text decoding, meaning construction, and critical analysis of texts. The participating teachers believed strongly that reading and writing are transactional and interactional practices. However, they were less certain in their beliefs about teaching critical literacy including the critical, analytical and evaluative aspects of text reading. Some teachers saw a conflict between using time on teaching critical literacy and preparing students to pass their exams. As critical literacy is not a requirement at exams, they found it difficult to justify using time teaching it. The results suggest that the teachers’ belief systems are strongly influenced by the broad macro-structure of the educational system in Singapore and their own educational experiences.  相似文献   

Decoding the phonics screening check          下载免费PDF全文

Catherine A. Darnell  Jonathan E. Solity  Helen Wall 《British Educational Research Journal》2017,43(3):505-527

The statutory ‘phonics screening check’ was introduced in 2012 and reflects the current emphasis in England on teaching early reading through systematic synthetic phonics. The check is intended to assess children's phonic abilities and their knowledge of 85 grapheme–phoneme correspondences (GPCs) through decoding 20 real words and 20 pseudo words. Since the national rollout, little attention has been devoted to the content of the checks. The current paper, therefore, reviews the first three years of the check between 2012 and 2014 to examine how the 85 specified GPCs have been assessed and whether children are only using decoding skills to read the words. The analysis found that out of the 85 GPCs considered testable by the check, just 15 GPCs accounted for 67% of all GPC occurrences, with 27 of the 85 specified GPCs (31.8%) not appearing at all. Where a grapheme represented more than one phoneme, the most frequently occurring pronunciation was assessed in 72.2% of cases, with vocabulary knowledge being required to determine the correct pronunciation within real words where multiple pronunciations were possible. The GPCs assessed, therefore, do not reflect the full range of GPCs that it is expected will be taught within a systematic synthetic phonics approach. Furthermore, children's ability to decode real words is dependent on their vocabulary knowledge, not just their phonic skills. These results question the purpose and validity of the phonics screening check and the role of synthetic phonics for teaching early reading.  相似文献
