Reading Instruction for English Learners in the Middle Grades: a Meta-Analysis     

Colby Hall  Garrett J. Roberts  Eunsoo Cho  Lisa V. McCulley  Megan Carroll  Sharon Vaughn 《Educational Psychology Review》2017,29(4):763-794

This meta-analysis synthesizes the last two decades of experimental and quasi-experimental research on reading instruction across academic contexts (e.g., social studies, science, mathematics, English language arts) for English learners (ELs) in grades 4 through 8, to determine (a) the overall effectiveness of reading instruction for upper elementary and middle school students who are ELs and (b) how the magnitude of the effect varies based on student, instructional, and study characteristics. The analysis included a total of 11 studies with 46 individual effect sizes and yielded a mean effect size of g?=?0.35 across all (i.e., standardized and unstandardized) reading measures, g?=?0.01 across standardized reading measures, and g?=?0.43 across unstandardized reading measures. For all reading, unstandardized reading, all vocabulary, and unstandardized vocabulary measures, results suggest that higher quality studies tended to have smaller effects, and these effects were even more evident for unstandardized measures (i.e., one unit increase in study quality was associated with decreased effects: g?=?0.21, g?=?0.30, g?=?0.24, g?=?0.30, respectively). For all comprehension measures, effects were larger for instruction that included both vocabulary and comprehension (g?=?0.39) than for instruction that focused on vocabulary alone (g?=?0.08). Results suggest the benefit of developing and refining high-impact approaches to reading instruction for ELs that can be delivered across content areas and grades.  相似文献   

Faculty Liaisons: an embedded approach for enriching teaching and learning in higher education     

Afsaneh Sharif  Ashley Welsh  Jason Myers  Brian Wilson  Judy Chan  Sunah Cho 《International Journal for Academic Development》2019,24(3):260-271

This paper explores the experiences of a group of academic developers who support educational development work as Faculty Liaisons at a large, research-intensive university. These academic developers inhabit complex ‘third spaces’, providing support through an embedded partnership relationship that requires lateral movement across functional and organizational boundaries to create new professional spaces, knowledge, and relationships. The authors utilize narrative inquiry and auto-ethnographic approaches to present an interpretive qualitative analysis of their experiences supporting Faculty and University projects across complex and evolving organizational boundaries. From this analysis, they highlight key roles and responsibilities associated with their blended context and identify challenges that academic developers who occupy third spaces within academic organizations face as they negotiate competing interests, identities, and requirements associated with the diverse range of their projects and the blended experience of working in scholarly and administrative, central- and Faculty-based roles. The lessons they have learned from these experiences will be of particular interest to academic developers who are experiencing the flux of change within higher education settings that are impacting teaching and learning practices both for faculty in the classroom and for those across the institution who support them.  相似文献   

Early Malnutrition and Child Neurobehavioral Development: Insights from the Study of Children of Diabetic Mothers   总被引：2，自引：0，他引：2

In this study we sought to discern whether disturbances in mothers' metabolism during pregnancy may exert long-range effects on the neurobehavioral development of the progeny. Participants were 139 Women with diabetes in pregnancy and their singleton offspring. Serial estimates of circulating maternal fuels were obtained for each pregnancy, along with detailed records of perinatal course and outcome. Offspring were administered the Wechsler Intelligence Scale for children—Revised (WISC-R) full-scale IQ scores below 70 in our cohort did not differ significantly from national estimates. Nonetheless, after statistically controlling for other influences, WISC-R verbal, performance, and full-scale IQ scores, and Bannatyne's indices of Verbal Conceptualization Ability, Acquired Knowledge, Spatial Ability, and Sequencing Ability were inversely correlated with measures, of maternal lipid and glucose metabolism in the second and third trimesters. KTEA Arithmetic scores were similarly correlated with measures of maternal lipids in the third trimester. All correlations indicate that poorer metabolic regulation was attended by poorer child performance. The effects of maternal metabolism on fetal brain and neurobehavioral development are discussed as potential intermediary factors.  相似文献   

Phonological awareness and morphological awareness: differential associations to regular and irregular word recognition in early Korean Hangul readers     

Jeung-Ryeul Cho  Catherine McBride-Chang  Soon-Gil Park 《Reading and writing》2008,21(3):255-274

A large battery of reading related skills were orally administered to 111 4-year old and 118 5-year old Korean kindergartners, who were also tested on reading of regular and irregular Korean Hangul words. In regression equations, speeded naming was uniquely associated with reading of both regular and irregular words. In contrast, only the three measures of phonological awareness at the levels of phoneme onset, coda, and syllable uniquely explained Hangul regular word recognition, whereas only morphological awareness consistently explained irregular word recognition. Results suggest somewhat different cognitive demands for reading of regular and irregular words, based on the dual-route model, in Korean Hangul.  相似文献   

近二十年汉语亲属词的概念结构研究综述     

赵钟淑 《山东教育学院学报》2008,23(2):77-79

对于亲属词进行深入的分析,这是汉语语义学研究的需要,也是词汇学、心理学、社会学研究的需要。笔者将近二十年的汉语亲属词的研究情况予以总结。汉语亲属词概念结构的组织维度至少有四个：亲属的亲密程度、姻亲,非姻亲、辈分和对象性别。汉语亲属词的分类既受亲属词的特性影响,也受知识和经验影响,同时还受文化影响。  相似文献   

Brief Research Report: Bayesian Versus REML Estimations With Noninformative Priors in Multilevel Single-Case Data     

Eunkyeng Baek  S. Natasha Beretvas  Wim Van den Noortgate  John M. Ferron 《Journal of Experimental Education》2020,88(4):698-710

Abstract

Recently, researchers have used multilevel models for estimating intervention effects in single-case experiments that include replications across participants (e.g., multiple baseline designs) or for combining results across multiple single-case studies. Researchers estimating these multilevel models have primarily relied on restricted maximum likelihood (REML) techniques, but Bayesian approaches have also been suggested. The purpose of this Monte Carlo simulation study was to examine the impact of estimation method (REML versus Bayesian with noninformative priors) on the estimation of treatment effects (relative bias, root mean square error) and on the inferences about those effects (interval coverage) for autocorrelated multiple-baseline data. Simulated conditions varied with regard to the number of participants, series length, and distribution of the variance within and across participants. REML and Bayesian estimation led to estimates of the fixed effects that showed little to no bias but that differentially impacted the inferences about the fixed effects and the estimates of the variances. Implications for applied researchers and methodologists are discussed.  相似文献   

Designing Teaching and Assessment Methods for Diverse Student Populations     

Mika Cho  Edward Forde 《The International Journal of Art & Design Education》2001,20(1):86-95

The American student population is becoming increasingly diverse in terms of race and culture. To address this pluralism, a study of learning style preferences was developed for purposes of designing more relevant teaching and assessment methods. Different theories of learning styles were incorporated into a survey that was administered to 483 students at four major universities. This survey compared learning style preferences according to ethnic and socio‐economic categories. Although it initially focused on students in Art and Design, it was eventually expanded to other disciplines for more inclusive reliability. The statistical analyses of this study are presented with corresponding recommendations for more effective teaching and assessment practices.  相似文献   

Multiple perceptions of children's aggression: Differences across neighborhood,age, gender,and perceiver     

Cynthia Hudley  William D. Wakefield  Brenda Britsch  Su‐Je Cho  Tara Smith  Marlene Demorat 《Psychology in the schools》2001,38(1):43-56

We investigated how overtly aggressive behavior was differentially perceived by two types of perceivers, teachers and peers, as a function of student neighborhood, gender, and grade level. Participants (N= 765) were predominantly African American students in grades 3‐5 recruited from two urban public schools in southern California. The neighborhoods surrounding the two schools differed in levels of identified violent crime and economic levels. Teachers in the community experiencing more violence perceived student behavior to be relatively less aggressive and more similar across genders than did teachers in the less violent community. Peers in the community experiencing more violent crime perceived both boys and girls to be somewhat aggressive, whereas in the less violent community, boys were perceived as aggressive more so than were girls. In general, agreement between teacher and peer perceptions was stronger for boys than for girls. © 2001 John Wiley & Sons, Inc.  相似文献
