Externalizing Problems in Two-Year-Olds: Implications for Patterns of Social Behavior and Peers' Responses to Aggression

A sample of 48 two-year-old children selected on the basis of parents' responses to two administrations of the Child Behavior Checklist for two to three-year-olds was observed in peer interactions. Twenty-four of these children displayed symptoms of aggressive/destructive (externalizing) problems that were in the borderline clinical range (labelled “high risk”) and 24 children displayed few such symptoms (“low risk”). The children were observed in matched dyads (one high risk and one low risk child) across four tasks designed to vary in the degree of social participation they would elicit from the children. Across all tasks, children in the high risk group displayed significantly and consistently more aggressive behavior than the children in the low risk group. However, these high risk children did not differ from other children in terms of several indices of social and nonsocial play. In addition, when children were classified as high aggressive versus average versus low aggressive on the basis of laboratory behavior, children who displayed high amounts of aggression during the play sessions did not differ from less aggressive children on these indices of social play. Finally, the responses of non-aggressive dyad partners to aggressive acts indicated that children are responsive, in relatively subtle ways, to aggression. These results are discussed in terms of the implications of early problematic behavior for later indices of maladjustment that include social competence and peer rejection.     

Ratings by Counselors Without Teaching Experience And Their Principals Regarding Performance of Guidance Functions

This study compared principal and self ratings of performance of guidance functions for practicing counselors who did not have teaching experience. The sample consisted of 43 counselors and their principals from throughout the United States. The ratings indicate better-than-average initial counselor acceptance by administrators, teachers, students, and parents with the degree of acceptance being greater after they had counseled for a while. Principal and self ratings differed significantly on initial acceptance by students and present acceptance by other counselors. Ratings of acceptance by both school psychologists and social workers were below average. There was no significant difference in counselor and principal ratings of counselor understanding of various school procedures and policies or of their ability to perform basic guidance activities. A majority of the principals who had worked with the counselors with non-teaching backgrounds indicated they would recommend the hiring of such a person to their school board.     

A cross-age study of the understanding of five chemistry concepts

A sample of 100 students from junior high school physical science, high school chemistry, and introductory college chemistry were examined for understanding of five chemistry concepts. The concepts addressed were chemical change, dissolution of a solid in water, conservation of atoms, periodicity, and phase change. The amount of experience with the concepts (grade level) and reasoning ability (developmental level) were examined as possible sources of variation in student understanding. Differences in understanding with respect to grade level were found to be significant for the concepts of chemical change, dissolution of a solid, conservation of atoms, and periodicity. However, few of the students in the college chemistry sample exhibited sound understanding of chemical change, periodicity, or phase change. The use of particulate terms (atoms, ions, molecules) increased across the grade levels. Reasoning ability proved to be a significant factor for student understanding of conservation of atoms and periodicity. An examination of the number and types of misconceptions across the grade levels revealed several interesting patterns and suggested sources for the students' alternative conceptions.     

Classroom activities provide important support to children's computer experiences

Summary Concrete activities provide important support to children's computer experiences. While all quality environments for young children are full of materials and resources, research suggests that children gain most from computer experiences if they are reinforced with specific concrete activities. Teachers utilize one of two methods to ensure that children's learning is enriched by these “hands-on” experiences: Teachers select and/or design specific supplemental activities, or teachers integrate children's computer experiences into the overall curriculum.
