Emotional and Behavioral Predictors of Preschool Peer Ratings   总被引：11，自引：0，他引：11  

Susanne A. Denham  Marcia McKinley  Elizabeth A. Couchoud  Robert Holt 《Child development》1990,61(4):1145-1152

It was predicted that social cognitive, behavioral, and affective aspects of young children's social development would predict stable peer ratings of their likability. Measures of likability, emotion knowledge, prosocial and aggressive behavior, peer competence, and expressed emotions (happy and angry) were obtained for 65 subjects (mean age = 44 months). Sociometric ratings, particularly negative, were stable over 1- and 9-month time periods. Correlational analyses showed that emotion knowledge and prosocial behavior were direct predictors of likability. Prosocial behavior mediated the relations of gender and expressed emotions with likability (i.e., gender and expressed emotions were each related to prosocial behavior, and prosocial behavior was related to likability, but neither gender nor expressed emotions were related to likability with prosocial behavior partialled out). Knowledge of emotional situations similarly mediated the age-likability relation. Results uphold the early development of stable peer reputations and the hypothesized centrality of emotion-related predictors of likability.  相似文献   

Concurrent and predictive validity of parent reports of child language at ages 2 and 3 years     

Feldman HM  Dale PS  Campbell TF  Colborn DK  Kurs-Lasky M  Rockette HE  Paradise JL 《Child development》2005,76(4):856-868

The MacArthur-Bates Communicative Development Inventories (CDI; Dale, 1996; Fenson et al., 1994), parent reports about language skills, are being used increasingly in studies of theoretical and public health importance. This study (N = 113) correlated scores on the CDI at ages 2 and 3 years with scores at age 3 years on tests of cognition and receptive language and measures from parent-child conversation. Associations indicated reasonable concurrent and predictive validity. The findings suggest that satisfactory vocabulary scores at age 2 are likely to predict normal language skills at age 3, although some children with limited skills at age 3 will have had satisfactory scores at age 2. Many children with poor vocabulary scores at 2 will have normal skills at 3.  相似文献   

Integrating inquiry science and language development for English language learners     

Trish Stoddart  America Pinal  Marcia Latzke  Dana Canaday 《科学教学研究杂志》2002,39(8):664-687

The traditional approach to the education of language minority students separates English language development from content instruction because it is assumed that English language proficiency is a prerequisite for subject matter learning. The authors of this article take the alternate view that the integration of inquiry science and language acquisition enhances learning in both domains. The report describes a conceptual framework for science–language integration and the development of a five‐level rubric to assess teachers' understanding of curricular integration. The science–language integration rubric describes the growth of teacher expertise as a continuum from a view of science and language as discreet unrelated domains to the recognition of the superordinate processes that create a synergistic relationship between inquiry science and language development. Examples from teacher interviews are used to illustrate teacher thinking at each level. © 2002 Wiley Periodicals, Inc. J Res Sci Teach 39: 664–687, 2002  相似文献   

Blocking in landmark-based search in honeybees     

Ken Cheng  Marcia L. Spetch 《Learning & behavior》2001,29(1):1-9

Two experiments tested blocking in landmark-based search in honeybees. Honeybees in the experimental group were trained in Phase 1 with a single landmark in a constant spatial relation to the target (sugar water). In the compound training second phase, the landmark used in Phase 1 (blocking landmark) and a new landmark (blocked landmark) were presented at constant spatial relations to the target. The blocking and blocked landmarks differed from each other in color and position, and the blocking landmark retained the same spatial relationship to the target as in Phase 1. In Experiment 1, the control group experienced only Phase 2 training with two landmarks. In Experiment 2, the control group was trained with a different landmark in a different position in Phase 1. Blocking was found in both cases.  相似文献   

Situating gender: Marie E. Zakrzewska and the place of science in women's medical education     

Tuchman AM 《Isis; an international review devoted to the history of science and its cultural influences》2004,95(1):34-57

Marie E. Zakrzewska (1829-1902) is known among historians of women and medicine for her advocacy of the natural sciences at a time when most women physicians preferred to emphasize their nurturing qualities. This article suggests that Zakrzewska's views have been poorly understood because scholars have tried to position them along a fault line that divides femininity and sympathy from masculinity and science. It suggests instead that feminist scholarship on the "situatedness of gender" offers a more promising conceptual framework for understanding the diverse strategies women (and men) have utilized in trying to achieve their goals. Zakrzewska, unlike many of her colleagues, did not seek to empower feminine virtues as a way of justifying women's entry into the medical profession. Instead, she tried to reappropriate science for women and to use it as a weapon against the barriers designed to keep women out of the public sphere. She was fighting her own battle against the gendering of science.  相似文献   

Dynamics of list-server discussion on genetically modified foods     

Triunfol ML  Hines PJ 《Public understanding of science (Bristol, England)》2004,13(2):155-175

Computer-mediated discussion lists, or list-servers, are popular tools in settings ranging from professional to personal to educational. A discussion list on genetically modified food (GMF) was created in September 2000 as part of the Forum on Genetically Modified Food developed by Science Controversies: Online Partnerships in Education (SCOPE), an educational project that uses computer resources to aid research and learning around unresolved scientific questions. The discussion list "GMF-Science" was actively supported from January 2001 to May 2002. The GMF-Science list welcomed anyone interested in discussing the controversies surrounding GMF. Here, we analyze the dynamics of the discussions and how the GMF-Science list may contribute to learning. Activity on the GMF-Science discussion list reflected some but not all the controversies that were appearing in more traditional publication formats, broached other topics not well represented in the published literature, and tended to leave undiscussed the more technical research developments.  相似文献
