This study examines factors associated with the relative stability of peer rejection among elementary school-aged children. Forty-four initially rejected children (some of whom improved their social status while others remained rejected over a 2-year period) were recruited from a larger sociometric sample. Prospective analyses were conducted to determine whether peer nominated aggression and children's perceptions of their own status in fourth grade were predictive of status improvement by the end of fifth grade. In addition to prospective analyses, initially rejected children and their mothers were invited to participate in a retrospective interview about their social experiences over the past 2 school years. Results of prospective and retrospective analyses suggested that perceived social status, participation in extracurricular activities, locus of control, and parental monitoring were all positively related to status improvement among initially rejected children. Surprisingly, aggressive behavior also was positively related to status improvement among initially rejected boys.  相似文献

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

The automatic letter-sound integration hypothesis proposes that the decoding difficulties seen in dyslexia arise from a specific deficit in establishing automatic letter-sound associations. We report the findings of 2 studies in which we used a priming task to assess automatic letter-sound integration. In Study 1, children between 5 and 7 years of age were faster to respond to a speech-sound when primed by a congruent letter, indicating that automatic activation of sounds by letters emerges relatively early in reading development. However, there was no evidence of a relationship between variations in the speed of activating sounds by letters and reading skill in this large unselected sample. In Study 2, children with dyslexia demonstrated automatic activation of sounds by letters, though they performed slowly overall. Our findings do not support the theory that a deficit in automatic letter-sound integration is an important cause of reading difficulties but do provide further evidence for the importance of phonological skills for learning to read.  相似文献

Abstract

Reaction time of the batter in Softball is important because of short pitching distance and the speed of the pitcher. Nine pitchers were tested for speed and had an average velocity of 59.95 mph and a mean reaction time of .215 sec. was found for 258 students tested. With these averages, the ball would be 29.33 ft. from home plate before 116 of these students began their swing and in 41 cases the ball would be less than 20 ft from the plate. Pitchers with greater velocity would decrease the success of the batter if the reaction time remains the same.  相似文献

This research examines the issue of self-regulated learning among highly gifted elementary ( n = 93) and high school students ( n = 40) in science. Self-report measures assessed self-regulatory strategy use in science and a spectrum of environmental (perceived level of investigation) and individual prerequisites (motivational beliefs, goal orientation, epistemological beliefs and intentions). Firstly, high school students were experiencing less investigation in science, and test anxiety and work avoidance were more pronounced than with elementary students. Secondly, highly gifted girls' science-related motivational beliefs were less positive than those of boys. Thirdly, path analyses indicate that the level of investigation in the science learning environment strongly determines motivational and epistemological prerequisites of self-regulatory strategy use. The results indicate that exploration and discovery should be enabled and strengthened in science classrooms of highly gifted students.  相似文献

Design Principles for Distributed Knowledge Building Processes   总被引:10,自引:0,他引:10  
In this paper we explore various interpretations of the term distributed cognition, then turn our attention to communities grounded in the practice of collaborative knowledge building. We discuss CSILE (Computer-Supported Intentional Learning Environments), a technology designed to support contributions to a communal database. Shared responsibility for this community resource extends to aspects of school practice typically handled exclusively by teachers, and engagement in improving and connecting the contents of the database makes the process of knowledge building self-sustaining. We discuss knowledge building communities involving students and teachers, and end with discussion of design principles for distributed knowledge building processes.  相似文献

This review describes the state of existing knowledge with regard to dual language learners’ (DLLs) social–emotional development birth to age 5. The review focuses on several widely recognized dimensions of children's social–emotional development: self-regulation, social competence, social cognition, and problem behaviors. We begin by presenting a theoretical perspective that frames our understanding of the interplay between relational and contextual factors that contribute to the social–emotional well-being of DLLs. A targeted search of the literature identified 14 peer-reviewed studies published from 2000 to 2011 that examined social–emotional outcomes for young DLLs in family, school, and peer contexts. Results suggest that DLLs have at least equal (if not better) social–emotional outcomes compared to native English speakers. There is also some evidence that the use of the home language in early childhood classrooms can be a positive, moderating factor for DLLs’ social–emotional development. Contextual and individual characteristics are highly correlated with DLL status, making it difficult to develop clear conclusions about the unique influence of DLL status on social–emotional outcomes. We conclude by identifying avenues for future inquiry.  相似文献

American universities receive millions of dollars worth of media exposure every year via Public Service Announcements (PSAs) broadcast during their respective school's athletic competitions. This research explores the message strategies and executional devices used by NCAA FBS (National Collegiate Athletic Association Football Bowl Subdivision) classification schools during the 2010 football season. This study is the most comprehensive content analysis of this subject matter to date. 115 PSAs were examined, representing 111 of the 120 schools which comprise this tier of American higher education institutions. 51 variables were operationalised and are detailed in this article. These variables include messaging specific to institutional communications, as well as common creative approaches used within television advertising. Findings suggest that there is indeed a ‘sea of sameness’ across these communications and that few schools are creating unique messages. This article continues the theoretical work in this field by refining extant models for communication messages employed by higher education institutions.  相似文献
