Literacy instruction was observed in 6 fourth-grade and 4 fifth-grade classrooms over the course of 1 year. Using the method of constant comparison, commonalities among classrooms were identified in the areas of reading instruction, writing instruction, instructional materials, instructional goals, management, and classroom motivational orientation. Teachers in all classrooms provided a combination of authentic reading and writing experiences and explicit skills instruction. Dimensions of difference among classrooms were also identified with respect to the same set of instructional components. One important way that the classrooms differed was with respect to the methods and materials that each teacher considered to be the core of his or her pedagogy (e.g., one teacher's instruction centered on trade books and process writing, another's on cooperative exploration as part of theme-driven instruction). There were also some striking omissions noted in the instruction observed, including a lack of instruction in comprehension strategy and little or no instruction in self-regulation. In summary, contemporary fourth- and fifth-grade literacy instruction was found to be extremely complex, involving many teacher decisions about how it should proceed. The teachers described here managed this complexity by focusing on a particular set of instructional practices as the defining emphases around which their literacy programs were implemented. 相似文献

We present a multigroup multilevel confirmatory factor analysis (CFA) model and a procedure for testing multilevel factorial invariance in n-level structural equation modeling (nSEM). Multigroup multilevel CFA introduces a complexity when the group membership at the lower level intersects the clustered structure, because the observations in different groups but in the same cluster are not independent of one another. nSEM provides a framework in which the multigroup multilevel data structure is represented with the dependency between groups at the lower level properly taken into account. The procedure for testing multilevel factorial invariance is illustrated with an empirical example using an R package xxm2. 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

In contrast to the hypothesis that dyslexics possess phonological deficits that are neurological in origin, I suggest that the source of the deficit is primarily experiential--that dyslexics exhibit phonological deficits because they have not learned to read and spell in a way that develops their spelling knowledge so that it penetrates and comes to symbolize their phonological knowledge. Evidence from normal reading and spelling development as well as from comparisons of dyslexic and nondyslexic readers is offered to support this thesis. 相似文献

Studies have shown that children benefit from a spelling pronunciation strategy in remembering the spellings of words. The current study determined whether this strategy also helps adults learn to spell commonly misspelled words. Participants were native English speaking college students (N = 42), mean age 22.5 years (SD = 7.87). An experimental design with random assignment, pretests, training, and posttests assessed effects of the pronunciation strategy on memory for the spellings of 20 hard to spell words. Half of the participants were trained to read the words by assigning spelling pronunciations during learning (n = 21). The comparison group (n = 21) practiced reading the words normally without the strategy. Strategy trained adults recalled significantly more words, total letters, silent letters, and schwa vowel letters correctly than controls. Poor spellers benefited as much if not more from this strategy as good spellers. Results support orthographic mapping theories. Optimizing the match between spelling units and sound units, including graphemes and phonemes, syllables, and morphemes, to create spelling pronunciations when words are read enhances memory for spellings of the words. As a result, higher quality lexical representations are retained in memory. Results suggest the value of teaching college students this strategy to improve their ability to spell words correctly in their written work. 相似文献

Adolescents with word-reading skills below grade level were randomly assigned to one of three conditions. Those receiving interventions practiced reading 100 multisyllabic words, either by analyzing graphosyllabic units in the words or by reading the words as unanalyzed wholes. The third group received no special instruction. Posttests revealed that graphosyllabic instruction helped students to decode novel words, remember how to read words with practice, and remember the spellings of words when compared to controls. In contrast, whole-word instruction yielded no benefit on transfer tasks compared to controls. Effects were observed primarily among adolescents reading at a third-grade-equivalent level and less so at a fourth- and fifth-grade-equivalent level. Results are consistent with a connectionist view of word learning and indicate the importance of providing struggling readers with instruction and practice in how to fully analyze the graphosyllabic constituents of words. 相似文献

Although nonstandard dialects of English are legitimate forms of spoken language used by many Americans, students in U.S. schools must acquire writing competence using Standard English (SE). Participants in this study were 3rd- and 4th-grade African-American students who exhibited Black English Vernacular (BEV) features in their written work. Six syntactic features differing in BEV and SE were targeted. Students received one of three treatments to increase their use of the SE features in their writing: (1) exposure to SE features in stories; (2) story exposure plus explanation of SE rules; and (3) story exposure, SE rule instruction, and guided practice transforming sentences from BEV to SE features. The third treatment proved most effective in enabling students to translate BEV sentences into SE forms and to employ the targeted SE features in their free writing. Results indicate that having students practice translating nonstandard sentences that typify their own writing and providing corrective feedback are effective for teaching them to use SE forms in their writing. Findings are interpreted to support a social-cognitive view of self-regulated learning. Copyright 2000 Academic Press. 相似文献

The relationship between 2nd and 3rd grade teachers’ linguistic knowledge and spelling instructional practices and their students’ spelling gains from fall to spring was examined. Second grade (N = 16) and 3rd grade (N = 16) teachers were administered an instructional practices survey and a linguistic knowledge test. Total scores on the two instruments were not significantly related (r = 0.20), indicating two different constructs. Students (N = 331 2nd graders, N = 305 3rd graders) completed a 40 item spelling dictation test in the fall and spring. HLM analyses were conducted on subsamples of weaker spellers (Ns = 226 2nd graders and 50 3rd graders) who spelled fewer than 20 words correctly on the pretest. Limiting the sample to weaker spellers eliminated ceiling effects on pre- to posttest gains. Results revealed that 2nd grade teachers’ linguistic knowledge of phonemic units in words, their teaching of spelling strategies, the time they spent in weekly spelling instruction, and the greater the number of weaker spellers in their classrooms, were significant predictors of weaker spellers’ improvement in spelling. For 3rd grade teachers, HLM analyses were not significant perhaps due to lack of power. However, 3rd grade teachers’ phonemic knowledge was significantly correlated with weaker spellers’ gain scores. Results while correlational provide tentative support for the conclusion that teachers who are more knowledgeable about phonemes in words and who utilize more effective, research based spelling instruction are more successful in teaching spelling to weaker spellers. 相似文献
