Beyond type 1
Note: K. For all three groups, kindergarten aggression and male gender made significant contributions predicting third-grade aggression.
Negative Impact of High-Aggression Classrooms
The impact of beyond type 1 context variables beyond type 1 on location. School size predicted child aggression only for the urban African American children, and school poverty predicted child aggression for the urban African American and European children, but not the rural students. In terms of exposure to classroom aggression, the same pattern of findings emerged for all three groups, with the mean level of classmate aggression at each grade level Grades 1—3 making unique contributions to the prediction of student third-grade aggression.
These findings lend further support to a cumulative model of impact and further suggest that the level of classroom aggression to which children are exposed acts as a continuous variable and has a unique influence associated with each year of exposure.

Discussion The present study investigated the demographic distribution and impact of exposure to high-aggression classrooms on the development of child aggression in elementary school. Of particular beyond type 1 was uncovering the effects of different patterns of exposure to classrooms with high levels of student aggression on individual children's rates of aggression in school over time.

Overall, the study found that children's exposure to aggressive classroom contexts during their first 3 years of elementary school is an important factor contributing to the behavioral development of children in that setting. Demographics associated with exposure to high-aggression classrooms The study also yielded some important findings regarding associations among school and child demographics and risk of exposure to high-aggression classrooms.
As predicted, large urban schools serving many economically disadvantaged children were characterized by a preponderance of classrooms with high rates of student aggression. This beyond type 1 is consistent with prior research revealing elevated rates of student aggression in schools located in impoverished, risky urban areas Colder et al. Children living in high-poverty, urban areas are exposed to higher levels of violence and antisocial behavior in their community settings, and correspondingly, are more likely to show elevated levels of aggressive behavior at school than children living in safer neighborhoods Beyond type 1,perhaps reflecting their strategic use of aggression to contend with a host of environmental stressors that they encounter inside and outside of their schools.
The consequence apparent in the beyond type 1 of this study is that children attending schools in economically disadvantaged and high-crime neighborhoods are particularly likely to experience school classrooms where aggressive behavior is common among classmates.
Placement in risky school and classroom environments occurred more often for African American than for European American children, due primarily to the demographics of their schools and neighborhoods. That is, by virtue of their centralized urban location, the vast majority of African American children in the cinnamon cukorbetegséggel lived in communities and attended schools characterized by high rates beyond type 1 poverty and associated neighborhood risks.
This buttresses arguments made by a number of researchers Garcia Coll et al. Interestingly, however, even when school size, location, and student economic disadvantage were entered first into a regression, child ethnicity still contributed significant, albeit small additional variance to the prediction of aggressive classroom exposure.
This finding raises the possibility that tracking within schools further increases the risk that African American children will be exposed to aggressive classroom environments.
Although the present study focused on a selected group of urban schools in high-crime neighborhoods, a large number of American students attend similar schools. These statistics, along with the results of this study on the demographic characteristics of children at risk for exposure to high-aggression classrooms, underscore the importance that researchers have given to better understanding the influence of school context and ethnicity on child behavioral development Beyond type 1 Coll et al.
Patterns of exposure to high-aggression classrooms A central focus of the present study was to examine the degree to which the developmental timing or length of exposure to aggressive classroom contexts would influence the development of aggressive behavior problems in children.
Researchers have recognized that entrance into the first grade is an important developmental juncture for children, and that negative classroom experiences during this first-grade year can increase children's risk for long-term behavioral problems in the school setting Kellam et al. Although not studied directly in previous studies, there was also reason to believe that alternative models of classroom influence, such as those based on more recent or chronic temporal patterns of children's exposure to high-aggression classrooms, might also affect the development of child aggressive behavior in school.
The present study found mixed results regarding the effects of primacy exposure to high-aggression classrooms. When primacy effects were separated from the effects of recent and chronic exposure, as part of general linear modeling procedures, a single year of exposure in first grade did not increase aggression for any of the three groups of children studied African American urban, European American urban, or European American rural children.
This was an unexpected result and one that appeared consistent with a developmental model postulated by Belsky and MacKinnon beyond type 1 which early school adjustment problems are considered transitory, diminishing when followed by subsequent positive school experiences and beyond type 1 socialization experiences.
Results showed that exposure to beyond type 1 classrooms during the first grade did contribute to third-grade aggression scores, even after considering exposure during the second and third grades.

This was consistent across the geographic location of the participating schools and ethnicity of the participants. Taken together, findings suggest that, although the association between aggressive classrooms in Grade 1 and long-term behavior problems may have to do with a special priming effect of first-grade classroom environments, it may have more to do with the likelihood that children who experience highly aggressive first-grade classrooms are likely to also experience aggressive classrooms in their later school years.
A single year of exposure to high-aggression classrooms was consistently associated with elevated third-grade aggressive behavior compared with no exposure only when the exposure was recent, in the same year as the assessment of child outcomes. Hence, even 1 year of exposure may have a negative impact on child aggression, due possibly to peer contagion and social learning peer modeling, norm setting, and reinforcement supporting aggressive behaviors in those classrooms Dishion et al.
Strong evidence also emerged to support the hypothesis that exposure to high-aggression classrooms has cumulative effects on child behavioral adjustment. For children in the urban public schools, those with 3 years of exposure to aggressive classrooms had significantly higher third-grade aggression scores than those exposed to 2 years, which in turn, were significantly higher than the aggression scores of those who were not exposed to high-aggression classrooms.
The differences were quite marked, with the average third-grade aggression score of children experiencing multiple years of exposure elevated 1—2 SD above the average third-grade aggression score of children at the same sites who experienced no exposure to aggressive classrooms. In addition, in the multilevel models, the level of classroom aggression to which a child was exposed each year in Grades 1, 2, and 3, contributed beyond type 1 unique variance in predicting aggressive behavioral outcomes in third grade.
In high-aggression classrooms, children are likely to be exposed to higher levels of peer modeling, provocation, and reinforcement Dishion et al. Teachers struggling to maintain order in these classrooms may more often make use of coercive control tactics that may increase aggressive reactivity and decrease beyond type 1 school engagement fostered by more positive teacher-student relationships.
All of these factors may combine to account for the socializing impact of classmate aggression on student beyond type 1 outcomes.
It was hypothesized that student risk for exposure to high-aggression classrooms would be elevated for students attending large, urban, and economically disadvantaged schools, but that classroom contexts would contribute significantly to the prediction of child aggression for these students, beyond the influence of these school demographics.
Results of the mixed statistical analyses indicated that individual child aggression levels at the point of school entry were the strongest predictor of beyond type 1 aggression 3 years later, and that gender also made a significant contribution to this child outcome.
With baseline child aggression, gender, and these school demographics in the model, children's exposure to high-aggression classrooms accounted for a sizable and significant amount of variance in child third-grade aggressive outcomes for all three groups of children studied. These findings suggest that the impact of student poverty and school size on student behavior is more distal than the impact of the classroom context, and that these more general school demographics have less influence on child behavioral adjustment than the more proximal socialization influences exerted by teachers and peers in the beyond type 1 context.
The reliability of the findings regarding classroom influence across the three groups studied suggests that it is a robust contribution that can be identified even when the distribution of classroom contexts is attenuated by splitting the sample into demographic groups with differing risk rates for exposure.
The impact of classroom aggression on the development of aggressive behavior problems in children
The cumulative effects evident in the multilevel models indicate that exposure to aggressive classrooms may add to the risk of beyond type 1 aggressive behavior problems, suggesting that the prognosis for resilient recovery from early behavior problems may be particularly poor for at-risk children entering schools with a high likelihood of chronic exposure to poorly managed classrooms with a high concentration of aggressive peers.
Limitations and Future Directions This study did not include any direct observational measures of classroom peer interaction processes or teacher management processes, making it difficult to isolate the mechanisms of action that account for the apparent impact of exposure to aggressive classrooms on child behavioral adjustment.
In addition, although exposure to neighborhood violence and victimization was viewed in this study as a key determinant for child aggressiveness, the study did not contain any direct assessment of this risk factor. The associations between children's exposure to high rates of community violence and their behavior adjustment in school, especially for children attending schools in low-income, urban neighborhoods have been well documented Colder et al.
It is possible that the problems associated with children's encounters with violence in their neighborhoods might have had a substantial influence on their rates of aggression in the school settings.
Skills beyond school
Furthermore, the authors acknowledge the possibility that other school-level variables not investigated here might have had some effect on the student aggression levels studied. Hence, future research is needed to determine whether exposure to aggression in these school contexts contributes in additional ways to the socialization of aggression.
From a methodological standpoint, classroom aggression and student aggression were both assessed with teacher ratings in this study. Beyond type 1 possibility that teacher-rating biases accounted for or contributed to the irányítsd hatékonyságának diabetes mellitus exists primarily for analyses that included third-grade classroom environments and third-grade child outcomes, which shared a rating source the third-grade teachers.
The removal of individual aggression scores in the calculation of classroom aggression scores for each child and the use of PROC MIXED procedures, which take into account third-grade classroom nesting, provided some protection against the risk that findings reflect teacher-rating biases. In addition, the pattern of results appeared quite robust across analyses that include classroom aggression ratings from first- and second-grade teachers that involved ratings independent of the third-grade teacher ratings of child outcomes.
Despite these limitations, results of this study have important implications for future research on the development beyond type 1 childhood aggression. Undoubtedly, more research efforts should be aimed at advancing what is currently known about the influence of children's exposure to poorly managed, aggressive classrooms during their early elementary school years on their development of aggressive behavior problems in school.

An important aspect of this research should be on elucidating the underlying developmental processes by which children are shaped by teachers and peers to display elevated levels of acting out behaviors in the classroom.
On a broader scale, research should build upon the discoveries made in this and other studies Barth et al. The present study furthers findings by Kellam et al. This study documents for the first time the impact of recent and chronic negative classroom experiences on the behavioral development of children during their early school years.
However, the model used here was an additive one. Future efforts in this area that make use of broader transactional models that consider the complex and reciprocal interplay between individual, classroom, school contextual, and perhaps sociocultural factors not studied here e. Findings from the present study also have important implications for preventive interventions.
They suggest that we continue to explore and adopt ecological interventions for the classroom.
Simultaneously directing efforts to foster positive peer communities in schools and to promote nonaggressive, pro-social norms in classrooms and at wider school levels would be worthy directions for prevention work. The current findings shed light on a population of children at great risk for exposure to high-aggression classrooms during their early school years and its consequences on their behavioral development: low-income urban African American children.
These results should encourage researchers, service providers, and education policy makers alike to consider disparities in the academic experiences and opportunity structures afforded children in schools, with particular attention given to children in urban public school districts with the highest rates of economic disadvantage, who disproportionately tend to be children of color.
On the basis of present research findings, policies that support smaller class sizes in urban public schools, promote the training and retention of qualified teachers, and increasing comprehensive school-based strategies to address children's adaptation difficulties early beyond type 1 and across their elementary school years are worthy directions for future pursuit.
Clearly, further longitudinal work is needed to more fully explore and understand the impact of classroom social ecologies on children's behavioral development and school adjustment during elementary school.
