Development of English‐ and Spanish‐reading skills was explored in a sample of 251 Spanish‐speaking English‐language learners from kindergarten through Grade 2. Word identification and reading comprehension developed at a normal rate based on monolingual norms for Spanish‐ and English‐speaking children, but English oral language lagged significantly behind. Four categories of predictor variables were obtained in Spanish in kindergarten and in English in first grade: print knowledge, expressive language (as measured by vocabulary and sentence repetition tasks), phonological awareness, and rapid automatic naming (RAN). Longitudinal regression analyses indicated a modest amount of cross‐language transfer from Spanish to English. Hierarchical regression analyses indicated that developing English‐language skills (particularly phonological awareness and RAN) mediated the contribution of Spanish‐language variables to later reading. Further analyses revealed stronger within‐ than cross‐language associations of expressive language with later reading, suggesting that some variables function cross‐linguistically, and others within a particular language. Results suggest that some of the cognitive factors underlying reading disabilities in monolingual children (e.g., phonological awareness and RAN) may be important to an understanding of reading difficulties in bilingual children.  相似文献

Co-streaming classes have enabled library staff to extend open classes to distance education students and other users. Student evaluations showed that the model could be improved. Two areas required attention: audio problems experienced by online participants and staff teaching methods. Staff tested equipment and adjusted software configuration to improve user experience. Staff training increased familiarity with specialized teaching techniques and troubleshooting procedures. Technology testing and staff training were completed, and best practices were developed and applied. Class evaluations indicate improvements in classroom experience. Future plans include expanding co-streaming to more classes and on-going data collection, evaluation, and improvement of classes.  相似文献

Research Findings: This study examined associations of preschool type (i.e., urban and suburban Head Start and university-affiliated center) and teacher–child variables with positive and negative child outcomes among 145 preschoolers (74 boys). Differences emerged across preschools, with urban Head Start children scoring lowest on the emotional competence measures and university-affiliated preschoolers experiencing less peer victimization than urban and suburban Head Start preschoolers. Differences across preschool types were also found for the teacher–child variables, such that teacher–child closeness was lower and teacher–child conflict and dependence were highest in the urban Head Start preschool. Regression analyses revealed significant and meaningful interactions between preschool type and teacher–child relational quality in the prediction of children's social-emotional outcomes. Teacher–child conflict was negatively associated with emotion regulation and teacher–child dependence was associated with the highest levels of emotion regulation, but only for university-affiliated preschoolers. Suburban Head Start preschoolers experienced less prosocial attention than urban Head Start preschoolers, but only when teacher–child closeness was high. Teacher–child closeness was also a negative predictor of urban Head Start preschoolers’ prosocial attention. Practice or Policy: Results point to the importance of understanding the role of teacher–child relational quality in the social-emotional development of children exposed to different preschool and environmental contexts.  相似文献

Research Findings: Examining the effects of professional development of the early childhood workforce that fit within the constraints of government policy is crucial for identifying types and amounts of effective training and informing child care policy. The present study used a cluster-randomized trial to evaluate the effects of a professional development program for child care providers designed to meet the criteria for 2 state-level policies: (a) that child care providers working in licensed centers engage in 10 hr of professional development annually and (b) that all licensed child care settings provide 30 min of developmentally appropriate literacy activity daily. Results indicated that 10 hr of professional development focused on literacy was effective for significantly improving the literacy practices and knowledge of child care providers. However, it was not effective in eliciting substantial growth in child literacy outcomes, at least in the short term. The lack of child outcomes illustrates the importance of measuring professional development effects at both the provider and child levels. Practice or Policy: This study illustrates the importance of critically questioning and analyzing state policy, particularly dosage. In practice, dosage is an influential factor in how professional development is selected by programs and providers, because most policies only specify a required number of hours to be completed. The design of policy, which can influence both provider practice and child outcomes, relies upon alignment between early childhood research and policy.  相似文献

We describe a new approach to the use of video-based technology for conducting controlled experiments in classroom contexts. Specifically, we describe a process for editing video recordings of live classroom lessons to create multiple versions, such that only one aspect of the lesson is systematically varied. Other aspects of the instruction are all held constant, including audio, curricular content, student participation, and other notoriously hard-to-control details of the interactional context that impact learning (e.g., gestures, affect). These edited lesson versions can be randomly assigned to students by condition within classrooms to meet a high standard for random assignment. This technology provides opportunities for deriving causal data on the efficacy of teaching practices through stimuli approximating a typical everyday classroom context.  相似文献

The introduction of universal primary education in sub-Sahara African countries in the 1990s increased enrolment rates and provided opportunities to children who were previously not in school. Research demonstrates that eliminating fees is not the magic bullet that delivers universal access. This study seeks to determine risk factors associated with dropout among primary school children in the low-income areas of Nairobi. Qualitative data is from the Education Research Program, collected between June and July 2008. The study found that: dumpsites in the two slum sites of Korogocho and Viwandani lure children out of school; school levies still charged in schools keep children out of school; and chronic poverty within families lure girls aged 14–16 into transactional sex. In conclusion, the declaration of free primary education is not sufficient to realize improved educational attainment as dropout after initial entry negates the purpose for which it was introduced.  相似文献

The paper describes a collaborative curriculum development project implemented over 3 years at 2 universities in the Western Cape Province of South Africa. The project involved a short module in which students in their fourth year of study interacted and learnt collaboratively across the boundaries of institution, discipline, race and social class, about the concepts of community, self and identity. The pedagogic approach adopted is described, as well as the responses of the students, and a brief reflection on some of the learning outcomes attained. The paper considers the learning processes which the curriculum development team experienced, and suggests that in order to facilitate learning for an ‘uncertain world’, the curriculum designers, too, need to engage in learning processes in which they make themselves vulnerable, mirroring some of the learning processes they expect the students to undergo.  相似文献

Games are frequently used to promote math learning, yet the competitive and collaborative contexts introduced by games may exacerbate gender differences. In this study, 1st and 2nd grade children in the U.S. (ages 5–8; N = 274; 70% White, 15% Asian, 2% Black, 1% Native American, 14% mixed or other race; 17% Hispanic) played either a competitive, collaborative, or solo game to learn about a challenging novel math concept: proportion. Overall, both social contexts boosted perseverance and task attitudes. However, analyses revealed the competitive condition yielded gender differences in attention to proportion in the presence of competing cues, with older boys underperforming in the competition condition. Potential explanations for these findings, as well as implications for classroom math learning, are discussed.  相似文献

In 1999, Wilson and Batterham proposed a new approach to assessing the test–retest stability of psychometric questionnaires. They recommended assessing the proportion of agreement – that is, the proportion of participants that record the same response to an item – using a test–retest design. They went on to use a bootstrapping technique to estimate the uncertainty of the proportion of agreement. The aims of this short communication are (1) to demonstrate that the sampling distribution of the proportion of agreement is well known (the binomial distribution), making the technique of ‘bootstrapping’ redundant, and (2) to suggest a much simpler, more sensitive method of assessing the stability of a psychometric questionnaire, based on the test–retest differences (within-individuals) for each item. Adopting methods similar to Wilson and Batterham, 97 sport students completed the Social Physique Anxiety Scale on two occasions. Test–retest differences were calculated for each item. Our results show that the proportion of agreement ignores the nature of disagreement. Items 4 and 11 showed similar agreement (44.3% and 43.3% respectively), but 89 of the participants (91.8%) differed by just - 1 point when responding to item 4, indicating a relatively stable item. In contrast, only 78 of the participants (80.4%) recorded a difference within - 1 point when responding to item 11, suggesting quite contrasting stability for the two items. We recommend that, when assessing the stability of self-report questionnaires using a 5-point scale, most participants (90%) should record test–retest differences within a reference value of - 1.  相似文献

Abstract

In this study, we compared the effects of a 72-h exercise abstinence period and normal exercise on the affect and body dissatisfaction of 58 healthy women (mean age 26.1 years, s = 8.2) who exercised at least four times per week, and explored the relationship between the changes in affect and body dissatisfaction. Participants completed the UWIST-MACL and Body Dissatisfaction Scale to assess affect and body image, and were randomized to an abstinence or control group. Affect and body image for both groups were re-assessed following the 72-h abstinence period. Compared with the control group, the abstinence group had a significant decrease in hedonic tone and energetic arousal, and a significant increase in tense arousal and body dissatisfaction from pre-intervention to post-intervention. There were no significant relationships between the changes in body dissatisfaction and the components of affect. A 72-h exercise abstinence period resulted in increased affect disturbance and body dissatisfaction in regularly active women.  相似文献
