The Simple View of Reading (SVR) suggests that the components of reading comprehension are decoding and linguistic comprehension. Given research that suggests that fluency is a separate construct from decoding and linguistic comprehension in fourth grade, the aim of this study was to examine the role of fluency in the SVR model. Analyses of data from 248 fourth-grade children explored whether the influence of fluency on reading comprehension is direct or whether fluency plays an indirect role on reading comprehension as a mediator or moderator of decoding. Structural equation modeling and latent regression analyses revealed that reading fluency plays a mediating role in explaining the relation between decoding and reading comprehension. This novel finding is placed in the context of studies that reported either a direct effect or no effect of reading fluency in SVR. 相似文献

This study described the course of school failure by classifying the characteristics of 103 first-grade children who were at risk for such an outcome and examining their classroom environments over a 1- to 4-year period. We describe the association between empirically validated clusters of children and specific instructional arrangements that served to increase the risk of special education placement. We found that individual seatwork while other children were in a reading group significantly increased the risk of placement; on the other hand, small-group work was associated with nonplacement for one cluster of children (those with possible learning disabilities). Other results were inconclusive, but suggestive of patterns that may eventually assist in the definition of the elusive link between individual differences and classroom environments. 相似文献

In the face of accumulating research and logic, the use of a discrepancy between intelligence and reading achievement test scores is becoming increasingly untenable as a marker of reading disabilities. However, it is not clear what criteria might replace the discrepancy requirement. We surveyed 218 members of journal editorial boards to solicit their opinions on current and proposed definitional components and exclusion criteria. Three components were selected by over two‐thirds of the respondents: reading achievement, phonemic awareness, and treatment validity. However, only 30 percent believed IQ‐reading achievement discrepancy should be a marker. More than 75 percent of the respondents believed exclusion criteria should remain part of the definition. Mental retardation was the most frequently selected exclusion criterion despite rejection of intelligence test scores as a definitional component. Although the findings reflect uncertainty among experts on what elements should comprise a definition, they do signal a willingness to consider new approaches to the conceptually difficult task of defining reading disabilities. 相似文献

The purpose of this study was to examine the development of oral reading fluency in a sample of first-grade children. Using growth curve analysis, models of growth were identified for a combined sample of at-risk (AR) and not-at-risk (NAR) children, and predictors of growth were identified for the longitudinal AR sample in first and second grade. Large and serious differences in reading fluency growth between the AR and NAR samples were apparent early, replicating other reports. Theories of sight-word learning and reading fluency were supported, in that letter-sound fluency was a uniquely significant predictor of first-grade reading fluency. The effects of phonological awareness and rapid automatized naming were mediated by the other variables in the model. Growth in first-grade oral reading fluency accounted for the most unique variance in second-grade growth and end-of-year performance. The results suggest that word reading fluency should be regarded as developing concomitantly with early word recognition rather than as a later-developing skill. 相似文献

A Second-Order Conditionally Linear Mixed Effects Model With Observed and Latent Variable Covariates
A conditionally linear mixed effects model is an appropriate framework for investigating nonlinear change in a continuous latent variable that is repeatedly measured over time. The efficacy of the model is that it allows parameters that enter the specified nonlinear time-response function to be stochastic, whereas those parameters that enter in a nonlinear manner are common to all subjects. In this article we describe how a variant of the Michaelis-Menten (M-M) function can be fit within this modeling framework using Mplus 6.0. We demonstrate how observed and latent covariates can be incorporated to help explain individual differences in growth characteristics. Features of the model including an explication of key analytic decision points are illustrated using longitudinal reading data. To aid in making this class of models accessible, annotated Mplus code is provided. 相似文献

We conducted two case studies to evaluate the effectiveness of individualized remedial reading instruction linked to direct
measures of student learning and transfer. The participants were two first grade children at serious risk of reading failure.
The instruction targeted decoding of one syllable short vowel words and first emphasized onset-rimes and then phoneme manipulation.
Forty words organized into 10 rime patterns were targeted for instruction. Probes consisting of all the instructional words
were administered before each instructional session to monitor student progress. We also administered transfer probes to determine
if the children could apply their knowledge more broadly. Instruction with onset-rime units yielded excellent maintenance
and near transfer (novel words containing instructed rimes) but not far transfer (novel words derived from uninstructed rimes).
The instructional change to phoneme manipulation yielded better far transfer for one of the two children. We consider the
importance of administering measures that assess more than what is taught to get an accurate portrait of children’s responsiveness
to instruction. 相似文献

This study investigated a Tier 2 intervention in the context of a Response to Intervention (RTI) model for 123 fourth grade students who were identified as having a high probability of reading failure. A randomized control trial was used to evaluate the effects of a 24 session multi-component supplemental intervention targeting fluency and expository comprehension of science texts. Intervention students performed significantly higher on comprehension strategy knowledge and use and science knowledge, but not on word reading, fluency, or other measures of reading comprehension. Moderators of intervention effects were also examined; children at higher risk in the intervention condition appeared to benefit more in comparison to lower probability children in intervention and compared to higher probability children in the control condition. 相似文献

Blending and spelling training were compared in this experiment to determine which intervention would improve the decoding skills of two first-grade boys with learning disabilities who were in the phonetic cue stage of reading. Additionally, the two boys received pre- and posttest administrations of a phonemic segmentation task. Although neither intervention proved superior, the children met the learning criterion for both interventions and demonstrated both maintenance and generalization of their skills. They also improved their phonemic skills, even though independent training in this area was not provided. It appeared that the equivalence of the interventions may have been due to the intensive instructional setting and use of systematic error analysis procedures. 相似文献
