The primary goal in this study was to examine maternal support of numerical concepts at 36 months as predictors of math achievement at 4½ and 6‐7 years. Observational measures of mother–child interactions (= 140) were used to examine type of support for numerical concepts. Maternal support that involved labeling the quantities of sets of objects was predictive of later child math achievement. This association was significant for preschool (d = .45) and first‐grade math (d = .49), controlling for other forms of numerical support (identifying numerals, one‐to‐one counting) as well as potential confounding factors. The importance of maternal support of labeling set sizes at 36 months is discussed as a precursor to children's eventual understanding of the cardinal principle.  相似文献

We initiated and structured a single program that supervised teachers, some with neuroscience or psychology degrees, to collaborate and explore the effects of science of learning‐translated pedagogy. This article reports on the 34 findings from teacher‐led randomized controlled trials (RCTs) and replications. Teachers designed trials, looking at areas such as attention, memory, and spaced learning. Overall, positive effects were found over short periods (1–6 weeks; r = 0.15, p < .0001 [d = 0.30], N = 2,157). However, retrieval practice (testing as a learning experience) had differential effects mediated by age, approach, and lesson content. Results suggest science of learning‐translated pedagogy needs extensive replication to establish how best to use laboratory evidence in classrooms. Multiple planned replication of teacher‐led RCTs has potential as an evaluation tool, combining high levels of mundane realism with strong internal validity and the potential to build cost effective large samples for meta‐analysis.  相似文献

This study aimed to understand how relationships with peers and teachers contribute to the development of internalizing problems via children's social self‐concept. The sample included 570 children aged 7 years 5 months (SD = 4.6 months). Peer nominations of peer rejection, child‐reported social self‐concept, and teacher‐reported internalizing problems were assessed longitudinally in the fall and spring of Grades 2 and 3. Teacher reports of support to the child were assessed in Grade 2. Results showed that peer rejection impeded children's social self‐concept, which in turn affected the development of internalizing problems. Partial support was found for individual (but not classroom‐level) teacher support to buffer the adverse effects of peer problems on children's self‐concept, thereby mitigating its indirect effects on internalizing problems.  相似文献

Since its advent word processing has become a common writing tool, providing potential advantages over writing by hand. Word processors permit easy revision, produce legible characters quickly, and may provide additional supports (e.g., spellcheckers, speech recognition). Such advantages should remedy common difficulties among weaker writers/readers in grades 1–12. Based on 27 studies with weaker writers, 20 of which were not considered in prior reviews, findings from this meta-analysis support this proposition. From 77 independent effects, the following average effects were greater than zero: writing quality (d = 0.52), length (d = 0.48), development/organization of text (d = 0.66), mechanical correctness (d = 0.61), motivation to write (d = 1.42), and preferring word processing over writing by hand (d = 0.64). Especially powerful writing quality effects were associated with word processing programs that provided text quality feedback or prompted planning, drafting, or revising (d = 1.46), although this observation was based on a limited number of studies (n = 3).  相似文献

This study investigates heterogeneity in adolescents' trajectories of global self‐esteem (GSE) and the relations between these trajectories and facets of the interpersonal, organizational, and instructional components of students' school life. Methodologically, this study illustrates the use of growth mixture analyses, and how to obtain proper student‐level effects when there are multiple schools, but not enough to support multilevel analyses. This study is based on a 4‐year, six‐measurement‐point, follow‐up of 1,008 adolescents (Mage = 12.6 years, SD = 0.6 at Time 1.) The results show four latent classes presenting elevated, moderate, increasing, and low trajectories defined based on GSE levels and fluctuations. The results show that GSE becomes trait‐like as it increases and that school life effects, moderated by gender, played an important role in predicting membership in these trajectories.  相似文献

What strategies help ethnic minority adolescents to cope with racism? The present study addressed this question by testing the role of ethnic identity, social support, and anger expression and suppression as moderators of the discrimination–adjustment link among 269 Mexican‐origin adolescents (Mage = 14.1 years), 12–17 years old from the Midwestern U.S. Results from multilevel moderation analyses indicated that ethnic identity, social support, and anger suppression, respectively, significantly attenuated the relations between discrimination and adjustment problems, whereas outward anger expression exacerbated these relations. Moderation effects differed according to the level of analysis. By identifying effective coping strategies in the discrimination–adjustment link at specific levels of analysis, the present findings can guide future intervention efforts for Latino youth.  相似文献

Mental health disparities between sexual minority and other youth have been theorized to result in part from the effects of the stigmatization on social integration. Stochastic actor‐based modeling was applied to complete network data from two high schools in the National Longitudinal Study of Adolescent Health (Mage = 15 years, = 2,533). Same‐sex attracted youth were socially marginalized in a smaller predominantly White school but not in a larger, more racially diverse school. For both schools, homophily was a critical network feature, and could represent social support for and social segregation of such youth. These findings emphasize the school context in studying the social lives of sexual minority youth and suggest that youth may be better off socially in larger and more diverse schools.  相似文献

Neuroanatomical localization (NL) is a key skill in neurology, but learners often have difficulty with it. This study aims to evaluate a concise NL tool (NLT) developed to help teach and learn NL. To evaluate the NLT, an extended‐matching questions (EMQ) test to assess NL was designed and validated. The EMQ was validated with fourth‐year medical students and internal medicine and neurology residents. The NLT's usability was evaluated with third‐ and fourth‐year students, and the effectiveness was evaluated with an experimental study of second‐year students, using the EMQ as the outcome measure. Students were taught how to use both the NLT and textbook algorithms (control) to perform NL, then randomized into either group, and only allowed to use their assigned tool to complete the EMQ. Primary outcome was the difference in mean EMQ scores expressed as a percentage of total score. For EMQ validation, students (n = 56) scored lower than residents (n = 50) (76.7% ± 1.7 vs. 83.0% ± 1.6; mean ± standard error of mean, P < 0.009). The EMQ demonstrated good reliability (Cronbach's α 0.85) and generalizability (G‐coefficient 0.85). Third‐ (n = 77) and fourth‐year (n = 42) students found the NLT user‐friendly and helpful in their learning of NL. In the experimental study, scores were significantly higher for NLT group (n = 94) than for controls (n = 101) (42.5 vs. 37.0%, P = 0.014); the effect size (Cohen's d) was 0.36. The EMQ is validated to reliably assess NL and is generalizable, feasible, practical, and of low cost. The concise and user‐friendly NLT for NL was effective in aiding medical student performance of NL. Anat Sci Educ 11: 262–269. © 2017 American Association of Anatomists.  相似文献

This meta‐analytic review of 42 studies covering 8,009 participants (ages 4–20) examines the relation of moral emotion attributions to prosocial and antisocial behavior. A significant association is found between moral emotion attributions and prosocial and antisocial behaviors (= .26, 95% CI [.15, .38]; = .39, 95% CI [.29, .49]). Effect sizes differ considerably across studies and this heterogeneity is attributed to moderator variables. Specifically, effect sizes for predicted antisocial behavior are larger for self‐attributed moral emotions than for emotions attributed to hypothetical story characters. Effect sizes for prosocial and antisocial behaviors are associated with several other study characteristics. Results are discussed with respect to the potential significance of moral emotion attributions for the social behavior of children and adolescents.  相似文献

This meta-analysis synthesizes the empirical data on problem behaviors among foreign- (G1) and U.S-born (G2+) youth and explores the effects of immigrant status on youth internalizing and externalizing problems. A random effects meta-regression with robust variance estimates summarized effect sizes for internalizing and externalizing problems across 91 studies (N = 179,315, Mage = 13.98). Results indicated that G1 youth reported significantly more internalizing problems (g = .06), and fewer externalizing problems than G2+ youth (g = −.06). Gender and sample type moderated the effects. The findings provide a first-step toward reconciling mixed support for the immigrant paradox by identifying for whom and under what conditions the immigrant experience serves as a risk or protective factor for youth.  相似文献

The genetic effects on individual differences in reading development were examined using genome‐wide complex trait analysis (GCTA) in a twin sample. In unrelated individuals (one twin per pair, = 2,942), the GCTA‐based heritability of reading fluency was ~20%–29% at ages 7 and 12. GCTA bivariate results showed that the phenotypic stability of reading fluency from 7 to 12 years (= 0.69) is largely driven by genetic stability (genetic = 0.69). Genetic effects on print exposure at age 12 were moderate (~26%) and correlated with those influencing reading fluency at 12 (genetic r = 0.89), indicative of a gene–environment correlation. These findings were largely consistent with quantitative genetic twin analyses that used both twins in each pair (= 1,066–1,409).  相似文献

The present article reports results of a real‐world effectiveness trial conducted in Denmark with six thousand four hundred eighty‐three 3‐ to 6‐year‐olds designed to improve children's language and preliteracy skills. Children in 144 child cares were assigned to a control condition or one of three planned variations of a 20‐week storybook‐based intervention: a base intervention and two enhanced versions featuring extended professional development for educators or a home‐based program for parents. Pre‐ to posttest comparisons revealed a significant impact of all three interventions for preliteracy skills (= .21–.27) but not language skills (d = .04–.16), with little differentiation among the three variations. Fidelity, indexed by number of lessons delivered, was a significant predictor of most outcomes. Implications for real‐world research and practice are considered.  相似文献

Data from a sample of 462 Mexican‐American adolescents (= 10.4 years, SD = .55; 48.1% girls), mothers, and fathers were used to test an ethnic socialization model of ethnic identity and self‐efficacy that also considered mainstream parenting styles (e.g., authoritative parenting). Findings supported the ethnic socialization model: parents’ endorsement of Mexican‐American values were associated with ethnic socialization at fifth grade and seventh grade; maternal ethnic socialization at fifth grade and paternal ethnic socialization at seventh grade were associated with adolescents’ ethnic identity exploration at 10th grade and, in turn, self‐efficacy at 12th grade. The findings support ethnic socialization conceptions of how self‐views of ethnicity develop from childhood across adolescence in Mexican‐American children.  相似文献

To examine the unique functions of same‐ and cross‐ethnic friendships, Latino (n = 536) and African American (n = 396) sixth‐grade students (Mage = 11.5 years) were recruited from 66 classrooms in 10 middle schools that varied in ethnic diversity. Participants reported on the number of same‐ and cross‐ethnic friends, perceived vulnerability, friendship quality, and the private regard dimension of ethnic identity. Whereas same‐ethnic friendships were uniquely associated with stronger private regard, more ethnic diversity and cross‐ethnic friendships were uniquely associated with less perceived vulnerability. Multilevel structural equation modeling tested whether cross‐ethnic friendships mediated the diversity‐vulnerability relation. Although cross‐ethnic friendships did not significantly mediate this relation at the classroom level, these friendships predicted less vulnerability at the individual student level.  相似文献

This study examines the effects of teaching common complex grapheme‐to‐phoneme correspondences (GPCs) on reading and reading motivation for at‐risk readers using a randomised control trial design with taught intervention and control conditions. One reading programme taught children complex GPCs ordered by their frequency of occurrence in children's texts (a ‘simplicity principle’). The other reading programme taught children word usage. Thirty‐eight students participated in the 9‐week programme of 30 supplemental small group sessions. Participants in the complex GPC group performed significantly better at post‐tests with generally large value‐added effect sizes (Cohen's d) at both by‐participant and by‐item for spelling, d = 1.85, d = 1.16; word recognition with words containing taught GPCs, d = 0.96, d = 0.95; word recognition, d = 0.79, d = 0.61, and reading motivation, d = 0.34, d = 0.56. These findings suggest that the simplicity principle aids in structuring maximally effective supplemental phonic interventions.  相似文献

Despite global demand, the large-scale effects of social-emotional learning (SEL) programming in developing countries remain underexplored. Using a randomized control trial, this study examined the effectiveness of a school-wide SEL intervention—Programa Compasso (PC)—among 3,018 sociodemographically diverse, Portuguese-speaking children (Mage = 9.85 years) attending 90 public primary schools across Rio de Janeiro, Brazil in 2017. Average impacts of PC on children’s executive function, emotion knowledge, and behavior problems after one school year were null. Moderation analyses did, however, reveal evidence for positive impacts of PC on children’s labeling of emotional expressions and inhibitory control within low-homicide communities (d = 0.15 SDs), and null effects on these same outcomes in high-violence areas. Implementation and cultural considerations are discussed.  相似文献

Three pretest–posttest experiments were conducted to compare the effects of viewing versus interacting with either fantastical or real events on 4‐ and 6‐year‐old children's inhibitory control. Experiment 1 (= 72) suggested that although viewing fantastical events had a negative effect on inhibitory control, interacting with them produced no such disruption. Experiment 2 (= 17) also found that children's inhibitory control decreased after viewing fantastical events but not after interacting with them. In addition, functional near‐infrared spectroscopy (fNIRS) data showed that viewing fantastical events resulted in greater activation in the dorsolateral prefrontal cortex. Experiment 3 (= 72) showed that children's inhibitory control increased after viewing and interacting with real events. The implications for studying the effects of mobile devices are discussed.  相似文献

This study examined the effects of reading interventions from single‐case design studies for students with and at‐risk of emotional and behavioral disorders in grades K–12 using a quantitative synthesis. Seventeen studies met the selection criteria of having one more dependent variables meeting what works clearinghouse (WWC) design standards with or without reservations. Although students’ reading performance significantly improved from baseline to intervention phases (p < 0.001), the overall weighted average effect size was weak (Tau‐U = 0.58, 95% confidence interval = [0.54, 0.63]; d = 0.29); smaller effects were found on reading comprehension. Interventions were less effective for students in secondary grades, students with a comorbid disability, and students in substantially separate settings. While no studies meeting the selection criteria were conducted in inclusive settings, the teacher provided interventions were more effective than those provided by researchers suggesting the importance of the student–teacher relationship for reading instruction. Study limitations, areas for future research, and implications for school practices are discussed.  相似文献

Experimental intervention studies constitute the current dominant research designs in the autism education field. Such designs are based on a ‘knowledge‐transfer’ model of evidence‐based practice in which research is conducted by researchers, and is then ‘transferred’ to practitioners to enable them to implement evidence‐based interventions. While these research designs contribute important knowledge, they lead to a gap between what the research evidence may prescribe and what happens in practice, with a concomitant disparity between the priorities of researchers and practitioners. This paper discusses findings from the ESRC‐funded ‘SHAPE’ project, which adopted a different model of evidence‐based practice, focusing on knowledge co‐construction. Pupils (= 8), teachers (= 10), a speech and language therapist and a parent in three different school communities investigated creative ways in which children's social communication skills could be enhanced through technology use. Through a participatory methodology, digital stories were used as a method to enable engagement with the practical realities of the classroom and empower practitioners to construct and share their own authentic narratives. Participants articulated precise knowledge about the learning opportunities afforded to them and their pupils through quality interactions that were mediated by the technologies, as evidenced through digital stories. The SHAPE project shows that it is feasible to develop methodologies that enable genuine knowledge co‐construction with school practitioners, parents and pupils. Such co‐construction could offer realistic opportunities for pedagogical emancipation and innovation in evidence‐based practice as an alternative to the currently dominant and narrow model of knowledge transfer.  相似文献

Instructional animation versus static pictures: A meta-analysis   总被引:8,自引:0,他引:8  
A meta-analysis of 26 primary studies, yielding 76 pair-wise comparisons of dynamic and static visualizations, reveals a medium-sized overall advantage of instructional animations over static pictures. The mean weighted effect size on learning outcome is d = 0.37 (95% CI 0.25–0.49). Moderator analyses indicate even more substantial effect sizes when the animation is representational rather than decorational (d = 0.40, 95% CI 0.26–0.53), when the animation is highly realistic, e.g., video-based (d = 0.76, 95% CI 0.39–1.13), and/or when procedural-motor knowledge is to be acquired (d = 1.06, 95% CI 0.72–1.40). The results are in line with contemporary theories of cognitive load and multimedia learning, and they have practical implications for instructional design.  相似文献
