The effectiveness of an explicit, systematic reading intervention for first-grade students whose home language was Spanish and who were at risk for reading difficulties was examined. Participants were 69 students in 20 classrooms in 7 schools from 3 districts who initially did not pass the screening in Spanish and were randomly assigned within schools to a treatment or comparison group; after 7 months, 64 students remained in the study. The intervention matched the language of instruction of their core reading program (Spanish). Treatment groups of 3 to 5 students met daily for 50 min and were provided systematic and explicit instruction in oral language and reading by trained bilingual intervention teachers. Comparison students received the school's standard intervention for struggling readers. Observations during core reading instruction provided information about the reading instruction and language use of the teachers. There were no differences between the treatment and comparison groups in either Spanish or English on any measures at pretest, but there were significant posttest differences in favor of the treatment group for the following outcomes in Spanish: Letter-Sound Identification (d = 0.72), Phonological Awareness composite (d = 0.73), Woodcock Language Proficiency Battery-Revised Oral Language composite (d = 0.35), Word Attack (d = 0.85), Passage Comprehension (d = 0.55), and two measures of reading fluency (d = 0.58-0.75).  相似文献   

Phonological processing and emergent literacy in Spanish-speaking preschool children     

Anthony JL  Williams JM  McDonald R  Corbitt-Shindler D  Carlson CD  Francis DJ 《Annals of dyslexia》2006,56(2):239-270

Phonological awareness (PA), phonological memory (PM), and phonological access to lexical storage (also known as RAN), play important roles in acquiring literacy. We examined the convergent, discriminant, and predictive validity of these phonological processing abilities (PPAs) in 147 3-, 4-, and 5-year-old children whose native language was Spanish. Confirmatory factor analysis (CFA) supported the validity of each PPA as separate from general cognitive ability and separate from each other. Moreover, structural equation modeling found RAN uniquely associated with knowledge of Spanish letter names and Spanish letter sounds. PA was found the best predictor of children’s ability to distinguish alphabetic text from nonalphabetic text. Finally, general cognitive ability was only indirectly associated with emergent literacy skills via PPAs. These results highlight the importance of PPAs in the early literacy development of native Spanish speaking preschool children.  相似文献   

Judgments Regarding Appropriate Child Supervision to Prevent Injury: The Role of Environmental Risk and Child Age   总被引：13，自引：0，他引：13  

Lizette Peterson  Bernard Ewigman  Coleen Kivlahan 《Child development》1993,64(3):934-950

Parents, social service workers, and medical personnel failed to differ in the amount of time they estimated that children of 11 differing ages should be left without adult supervision within 5 different supervision domains. More hazardous circumstances dramatically reduced the amount of time respondents said children should be left unsupervised. Amount of unsupervised time increased with age, with clear developmental cutoffs that varied by level and type of risk. When the moderate center of the distribution was examined, 3 clear areas of consensus emerged. For most domains, constant supervision was recommended for preschool children. For early elementary school children, nearly constant (0–5 min without supervision) or close (0–15 min without supervision) supervision was recommended in safer locations, with constant supervision still recommended in high-risk situations. Only with older children was there an absence of consensus regarding supervision. The implications of these results for future injury prevention research are discussed.  相似文献   

The necessity of the alphabetic principle to phonemic awareness instruction

This investigation examined the extent to whichcurricular choice and incorporation of phonemicawareness (PA) into the kindergarten curriculumaffects growth in kindergarten literacy skillsand first-grade reading and spelling outcomesin 114 classrooms in 32 Title 1 schools for4,872 children (85% African American). Literacy curricula were described as havingmore or less teacher choice and more or less PAand were implemented with ongoing professionaldevelopment. Observations of curriculumfidelities and ratings of student behavior werealso obtained. Alphabetic instruction withoutPA was not as effective as alphabeticinstruction with PA. However, effectiveinstruction in PA and alphabetic codingappeared to be as much a consequence of ongoingprofessional development as it was a functionof prescribed PA activities. Results providelarge-scale classroom support for findings onPA reported by the National Reading Panel[(2000).

Relationship of rapid automatized naming and phonological awareness in early reading development: implications for the double-deficit hypothesis     

Schatschneider C  Carlson CD  Francis DJ  Foorman BR  Fletcher JM 《Journal of learning disabilities》2002,35(3):245-256

It is widely accepted that deficits in phonological awareness skills are related to reading difficulties. Recently, another source of reading difficulty has been identified that involves naming speed, and combined impairments in phonological skills and naming speed will produce more severe reading deficits than single deficits in either of these cognitive skills. The purpose of this study was to investigate the consequences of grouping children based on the presence or absence of deficits in these skills. We demonstrate that the greater severity of reading impairment found in children with a double deficit could be due in part to a statistical artifact caused by grouping children based on their performance on two correlated continuous variables. This artifact also makes it difficult to establish the relative impact of deficits in naming speed on reading ability independent of deficits in phonological awareness.  相似文献   

Explaining Variation in Findings From Efficacy and Effectiveness Studies for English Reading Interventions for English Learners     

Christopher D. Barr  Colleen K. Reutebuch  Coleen D. Carlson  Sharon Vaughn  David J. Francis 《Journal of research on educational effectiveness》2019,12(1):116-134

Beginning in 2002, researchers developed, implemented, and evaluated the efficacy of an English reading intervention for first-grade English learners using multiple randomized control trials (RCTs). As a result of this efficacy work, researchers successfully competed for an IES Goal 4 effectiveness study using the same intervention. Unlike the efficacy studies, the findings from the effectiveness study begun in 2011 did not yield significant differences in favor of the treatment. We investigated the identification and pre-intervention performance levels of students in efficacy and effectiveness RCT studies and provide data and compare samples from these studies as one means of explaining variation in findings. Findings indicate that pre-intervention performance levels are higher for students in effectiveness RCT studies. This article serves as an exemplar for other effectiveness studies that may not replicate findings from previous efficacy trials.  相似文献
