Reducing Children's Implicit Racial Bias Through Exposure to Positive Out‐Group Exemplars

Studies with adults suggest that implicit preferences favoring White versus Black individuals can be reduced through exposure to positive Black exemplars. However, it remains unclear whether developmental differences exist in the capacity for these biases to be changed. This study included 369 children and examined whether their implicit racial bias would be reduced following exposure to positive Black exemplars. Results showed that children's implicit pro‐White bias was reduced following exposure to positive Black exemplars, but only for older children (M_age = ~10 years). Younger children's (M_age = ~7 years) implicit bias was not affected by this intervention. These results suggest developmental differences in the malleability of implicit racial biases and point to possible age differences in intervention effectiveness.     

THE QUESTION OF EDUCATION SCIENCE: EXPERIMENTISM VERSUS EXPERIMENTALISM

The ascendant view in the current debate about education science — experimentism — is a reassertion of the randomized experiment as the methodological gold standard. Advocates of this view have ignored, not answered, long-standing criticisms of the randomized experiment: its frequent impracticality, its lack of external validity, its confinement to a regularity conception of causality, and its externalization of politics. This article rehearses these criticisms and then adumbrates the alternative of experimentalism . In contrast to experimentism, experimentalism is expansive and variegated in its conception of scientific method, seeing methodology as itself an object of experimentation. Experimentalism also includes a central role for intentional causation and self-consciously incorporates progressive political values.     

Behavior genetic analysis of mouse emotionality: II. Stability of factors across genotypes

Three emotionally divergent strains of mice (SWR/J, A/HeJ, and SJL/J) were mated to produce three populations: a pure strain population (N = 90), an F₁ population (N = 120), and an F₂ population (N = 96). All Ss were tested on a battery of measures of emotionality. Each population was factored separately by principal components factoring with varimax and promax rotations. Factorial invariance was assessed quantitatively by congruence coefficients. Eight of the resultant factors were found to be replicable across populations. These were autonomic balance, motor discharge, territorial marking, acrophobia, tunneling-1, tunneling-2, underwater swimming, and audiogenic reactivity. Of the eight factors, motor discharge was most distinct in each population and tunneling-1 was least distinct.     

China's Changing Educational System

In light of the 50th anniversary of the Brown v. Board of Education (1954) ruling, this article focuses on how the majority opinion in Brown set a precedent for the use of social science research in defining and examining inequity in education. This article argues that following Brown, social science research has gained prominence in its social function in shaping the debate in equal educational opportunity. Whereas Brown introduced racial desegregation in the governmental agenda, social science research since the 1960s has sustained the societal concerns on the challenge of inequality. This article examines how the use of social science research in Equality of Educational Opportunity (J. S. Coleman et al., 1966), an extensive study of schools and schooling under the direction of James Coleman of Johns Hopkins University and Ernest Campbell of Vanderbilt University during the mid 1960s, shaped the course of education research and policy toward the notion of equal educational opportunities. Further, this article discusses the more recent work of William Julius Wilson (1987) that shifts the equality of opportunity debate out of the courts and from individual and group opportunities to the equality of life chances.     

The neural correlates of working memory training in typically developing children

Working memory training improves children's cognitive performance on untrained tasks; however, little is known about the underlying neural mechanisms. This was investigated in 32 typically developing children aged 10–14 years (19 girls and 13 boys) using a randomized controlled design and multi-modal magnetic resonance imaging (Devon, UK; 2015–2016). Training improved working memory performance and increased intrinsic functional connectivity between the bilateral intraparietal sulci. Furthermore, improvements in working memory were associated with greater recruitment of the left middle frontal gyrus on a complex span task. Repeated engagement of fronto-parietal regions during training may increase their activity and functional connectivity over time, affording greater working memory performance. The plausibility of generalizable cognitive benefits from a neurobiological perspective and implications for neurodevelopmental theory are discussed.     

EFFECTS OF TEACHER–STUDENT RELATIONSHIPS ON PEER HARASSMENT: A MULTILEVEL STUDY

Peer harassment is a major social problem affecting children and adolescents internationally. Much research has focused on student‐to‐student harassment from either an individual or a multilevel perspective. There is a paucity of multilevel research on students’ relationships with the classroom teacher. The purpose of this study was to use a socioecological perspective to examine the relationships between individual student‐level characteristics, problematic teacher–student relationships, and student‐reported peer harassment. A total of 1,864 children (50.7% female) aged 8 to 13 years (M = 9.82, SD = 1.24), nested in 27 schools (58.2% public) in Spain, participated in the study. Ninety‐four homeroom teachers reported on teacher–student relationships, and students completed self‐report measures related to peer harassment and teacher–student relationships. Multilevel models showed that relationships between students and teachers exerted a varying degree of influence on classroom levels of peer harassment. Specifically, student‐reported teacher support was associated with diminished student‐reported peer victimization, whereas direct and indirect student‐reported teacher‐to‐student aggression was associated with increased peer victimization. Additionally, student‐reported student‐to‐teacher aggression and teacher‐to‐student aggression were associated with increased student‐reported peer aggression. Teacher‐reported variables at the classroom level, however, contributed little to student‐reported outcomes. Results are discussed in the context of future research on relationships between teachers and students.     

Screening for hearing loss in early childhood programs

This study assessed the feasibility of doing hearing screening in Migrant, American Indian and Early Head Start programs using otoacoustic emissions (OAE) technology. Staff members were trained to screen 0–3-year-old children for hearing loss using hand-held OAE equipment and a multi-step screening and referral protocol. Of the 3486 children screened as a part of the study, 77% passed an OAE screening at the first step, 18% more passed an OAE screening at the second step, and 5% were ultimately referred for medical or audiological follow-up. Eighty children were identified as having a hearing loss or disorder of the outer, middle or inner ear requiring treatment. Of these 80, six had permanent bilateral or unilateral hearing loss. Although the protocol suggested that the multi-step screening procedure should be completed within a 4-week time period or less, analysis of the data showed that for children requiring more than an initial OAE screening, the length of time over which the screening was completed ranged from 7 to 12 weeks. The median time required to complete a single OAE screening session was 4 minutes per child. The results demonstrate that OAE screening of young children using this protocol is practical and effective. The implications for conducting periodic hearing screening throughout early childhood are discussed.     

The persistence of preschool effects: Do subsequent classroom experiences matter?

Using rich longitudinal data from the Early Childhood Longitudinal Study-Kindergarten cohort (ECLS-K), we find that children who attended preschool enter public schools with higher levels of academic skills than their peers who experienced other types of child care (effect size of .14). This study considers the circumstances under which the preschool advantage persists, that is, the types of classrooms in which students who did not attend preschool “catch up” to their counterparts who did. Specifically, we focus on two dimensions of the early school environment—class size and the level of academic instruction provided. The findings suggest that most of the preschool-related gap in academic skills at school entry is quickly eliminated for children placed in small classrooms and classrooms providing high levels of reading instruction. Conversely, the initial disparities persist for children experiencing large classes and lower levels of reading instruction. These results point out that the longer-term effects of early childhood experience partly depend on classroom experiences during at least the first years of school.     

Teacher and school characteristics and their influence on curriculum implementation

Reform‐based curriculum materials have been suggested as a mechanism to make inquiry‐based instruction more prevalent in secondary science classrooms, specifically when accompanied by comprehensive professional development (Loucks‐Horsley, Hewson, Love, & Stiles, 1998 ; Powell & Anderson, 2002 ). This research examines the implementation of a reform‐based high school chemistry curriculum in a large, urban school district. We explicitly consider the role of the teachers' knowledge and beliefs in their implementation of the reform‐based chemistry curriculum, as well as school level factors. Qualitative and quantitative data were collected in the form of beliefs interviews and classroom observations from 27 high school chemistry teachers. Analysis of the data revealed that implementation of the curriculum was strongly influenced by the teachers' beliefs about teaching and learning, and the presence of a supportive network at their school sites. © 2007 Wiley Periodicals, Inc.

Variation among schools on classroom practices in science based on TIMSS‐1999 in Turkey

The purpose of this study was to investigate the differences among schools using student responses in the Trends in Mathematics and Science Study–1999 (TIMSS‐99) data. Schools were classified into two groups based on eighth grade students' overall achievement in science. Two different discriminant function analyses were performed to distinguish high‐ and low‐performing schools, based both on classroom practices and factor structures (student‐centered activities, teacher‐centered activities, attitudes toward technology use, socioeconomic status [SES], and doing well in science). The results indicate that there were significant differences between the two classifications of schools on ten variables regarding classroom practices and activities, and 29 variables regarding classroom practices, attitudes toward science, use of the computer and overhead projector (OHP), parental background characteristics, and need to do well in science. Contrary to general expectations, technology use (computer, OHP, etc.) was found to be negatively related to science achievement. Teachers should be trained on how to use technology in their classrooms. Turkey recently revised its curriculum to a student‐centered approach and this might increase students' ability to transfer knowledge into real life. Teachers and schools should pay more attention to SES effects. Teachers should also work toward building students' confidence in science. © 2007 Wiley Periodicals, Inc.
