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

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

Systematic errors in pigeons’ memory for event duration: Interaction between training and test delay     

Marcia L. Spetch 《Learning & behavior》1987,15(1):1-5

Pigeons trained to choose different stimuli following short- and long-duration signals make disproportionately more “short” choices (i.e., “choose-short errors”) following an increase in the retention interval and more “choose-long errors” following a decrease in this delay. The present experiment provided a systematic investigation of how these selective errors depend on the relationship between the training delay and the test delay. Pigeons were first trained with a 0-sec delay between the signal (2- or 8-sec food presentations) and the choice stimuli (red- and blue-lit keys). On subsequent test trials with 5- and 10-sec delays, choose-short errors predominated. Next, the birds were trained with a constant 10-sec delay and then tested with shorter or longer delays on some trials. The birds now responded accurately and without selective errors at the 10-sec training delay, but made choose-long errors at shorter delays and choose-short errors at longer delays. Finally, the birds were trained with a constant 20-sec delay and then tested with shorter and longer delays. Choose-long errors again appeared at shorter test delays, choose-short errors at longer test delays, and no differential errors at the 20-sec training delay. The selectivity of these errors generally increased with the absolute difference between the training and test delay. Theoretical implications of these results are discussed.  相似文献   

Evaluation of the science enrichment activities (SEA) program: A decision oriented model     

Marcia C. Linn 《Studies in Educational Evaluation》1978,4(2):83-90

This study examined three questions of interest to decision-makers. Results revealed that subjects made some cognitive gains and chose different types of activities. The most striking finding relates to the third question. Groups who chose different activities made similar gains in learning. Older subjects perform fewer activities but make gains similar to those made by younger subjects. These results suggest that either eighth graders learn in less time or more activities are not proportionately more instructive. A question for future studies is whether subjects who choose more challenging activities make proportionately greater gains in understanding how to control variables. Of particular importance, it was found that subjects who are more sophisticated on the basis of age or ability to control variables choose proportionately more difficult activities (those with larger numbers of variables or with unfamiliar variables). This supports Hunt's (1965) suggestion that the learner is able to select experiences which help him to learn. The decision-makers concluded that open education programs might succeed, in part, because students are able to choose experiences which help them learn. These results do not, however, imply that student selection of educational activities is the most appropriate form of instruction.This study combined with earlier studies (Linn, Chen & Thier, 1977) strongly suggests that the most one can expect students to learn in the SEA program is to criticize experiments. Even for eighth graders who are presumably more likely to learn to control variables, the SEA is not sufficient to teach controlling variables. A different approach is needed to teach this (e.g., Linn, in press).Several research and evaluation studies are consistent with the findings of this evaluation (e.g., Shann et al., 1975; Atkinson, 1976). Many educators interested in “open” education have suggested that interactive learning experiences teach children to be autonomous, curious, and able to plan investigations. These questions were suggested by the evaluators as meriting further study.The decision-making model employed in this evaluation succeeded in influencing decision-makers and also in suggesting some implications for future studies. Rather than focusing on program objectives the evaluation focused on program decisions. Setting priorities in evaluation studies is a multivariate process not fully discussed in this paper. Greater emphasis needs to be placed on the potential benifit of an evaluation plan rather than on a set of program objectives.  相似文献   

Determinants of pigeons’ choice between certain and probabilistic outcomes     

Marcia L. Spetch  Michael V. Mondloch  Terry W. Belke  Roger Dunn 《Learning & behavior》1994,22(3):239-251

Pigeons chose between 50% and 100% reinforcement on a discrete-trials concurrent-chains procedure with fixed-ratio 1 initial links and fixed-time terminal links. The 100% alternative always provided food after a terminal-link delay, whereas the 50% alternative provided food or blackout equally often after a delay. Additionally, the terminal-link stimuli on the 50% alternative were correlated with the outcomes in signaled, but not in unsignaled, conditions. The effects of intertrial-interval duration and length of the terminal-link delays on choice of the 50% alternative were investigated in four experiments. Preference for the 50% alternative varied with signal condition and duration of the terminal link leading to food, but not with duration of either intertrial interval or the terminal link leading to a blackout. The results are discussed in terms of conditioned-reinforcement effects, Mazur’s hyperbolic-decay model, and delay reduction. This research was supported by a Natural Sciences and Engineering Research Council of Canada research grant awarded to the first author.  相似文献
