Benefits of practicing 4 = 2 + 2: nontraditional problem formats facilitate children's understanding of mathematical equivalence     

McNeil NM  Fyfe ER  Petersen LA  Dunwiddie AE  Brletic-Shipley H 《Child development》2011,82(5):1620-1633

This study examined whether practice with arithmetic problems presented in a nontraditional problem format improves understanding of mathematical equivalence. Children (M age = 8;0; N = 90) were randomly assigned to practice addition in one of three conditions: (a) traditional, in which problems were presented in the traditional "operations on left side" format (e.g., 9 + 8 = 17); (b) nontraditional, in which problems were presented in a nontraditional format (e.g., 17 = 9 + 8); or (c) no extra practice. Children developed a better understanding of mathematical equivalence after receiving nontraditional practice than after receiving traditional practice or no extra practice. Results suggest that minor differences in early input can yield substantial differences in children's understanding of fundamental concepts.  相似文献

Implicit attitudes toward children may be unrelated to child abuse risk     

Risser HJ  Skowronski JJ  Crouch JL 《Child abuse & neglect》2011,35(7):514-523

Objective

To explore whether adults possess implicit attitudes toward children and whether those attitudes are especially negative among respondents who are high in child physical abuse (CPA) risk.

Methods

The present study used an implicit evaluative priming procedure. In this procedure, participants were instructed to make decisions about the evaluative implications of target words. These words were preceded by photographs of child faces or adult faces displaying positive, neutral, or negative expressions. Reaction times for the evaluative decisions were used as an index of the extent to which photos invoked negative or positive evaluative reactions.

Results

Results from 2 studies, the first conducted on a student sample (N = 90) and the second on a parent sample (N = 95), demonstrated that evaluative congruence between the facial expressions displayed in photographs and the target words facilitated responses. Furthermore, the results suggested that regardless of CPA risk, child faces, relative to adult faces, facilitated responses to negative target words, suggesting an out-group bias. This implicit out-group bias was not moderated by respondents’ CPA risk status.

Conclusions

Faces of children, relative to faces of adults, appear to activate negative information structures that facilitate evaluative decisions of negative stimuli, suggesting an out-group bias. Given that out-group biases typically lead to less favorable treatment of out-group members, additional research is needed to examine the pervasiveness of negative evaluative biases towards children and the potential implications of such biases on children's lives. Further, research examining whether high CPA risk parents and low CPA risk parents differ in how they manage initial negative evaluative reactions is needed.  相似文献   

A comparison of online versus traditional student end‐of‐course critiques in resident courses     

Rodger Morrison 《Assessment & Evaluation in Higher Education》2011,36(6):627-641

This study outlines the intraclass differences between online and traditional student end‐of‐course critiques (EOCCs) only in the context of resident courses. Previous research into these differences appears limited to studies that compare entire classes rather than studies within any given class. Hypotheses are stated that the administration method has an effect on: how students will rate EOCCs, EOCC response rates, and, the detail level, favourability level and number of EOCC comments. In this field experiment, students in resident business courses at a large university comprised the sample. Individuals from within each class were randomly assigned either to a control group that completed a traditional paper‐based EOCC or to an experimental group that completed a similar EOCC online. Comments were coded with regard to the level of detail, favourability and total number of comments. Analysis of variance was used to compare the two groups with regard to ratings, comments and response rates. Online EOCCs had lower response rates, lower overall ratings, but more detailed comments. The methodology had no significant effect on the number or favourability level of comments.  相似文献

Are You Satisfied? PhD Education and Faculty Taste for Prestige: Limits of the Prestige Value System     

Emory Morrison  Elizabeth Rudd  Joseph Picciano  Maresi Nerad 《Research in higher education》2011,52(1):24-46

This paper empirically evaluates Caplow and McGee??s (The academic marketplace, 1958) model of academia as a prestige value system (PVS) by testing several hypotheses about the relationship between prestige of faculty appointment and job satisfaction. Using logistic regression models to predict satisfaction with several job domains in a sample of more than 1,000 recent social science PhD graduates who hold tenure-track or tenured faculty positions, we find that the relationship between prestige of faculty appointment and job satisfaction is modified by PhD program prestige. Graduates of high prestige PhD programs value prestige more highly and graduates of low prestige programs value salary more highly. We explain our findings by incorporating reference group theory and a theory of taste formation into our model of the academic PVS, which identifies PhD programs as sites of socialization to different tastes for prestige (a process of cultural transmission) in addition to their well recognized role in transmission of human and social capital. We discuss practical and theoretical implications of our findings in relation to efforts to measure PhD program quality and to understand the structure of academic labor markets.  相似文献

Contextual gaps: privacy issues on Facebook     

Gordon Hull  Heather Richter Lipford  Celine Latulipe 《Ethics and Information Technology》2011,13(4):289-302

Social networking sites like Facebook are rapidly gaining in popularity. At the same time, they seem to present significant privacy issues for their users. We analyze two of Facebooks’s more recent features, Applications and News Feed, from the perspective enabled by Helen Nissenbaum’s treatment of privacy as “contextual integrity.” Offline, privacy is mediated by highly granular social contexts. Online contexts, including social networking sites, lack much of this granularity. These contextual gaps are at the root of many of the sites’ privacy issues. Applications, which nearly invisibly shares not just a users’, but a user’s friends’ information with third parties, clearly violates standard norms of information flow. News Feed is a more complex case, because it involves not just questions of privacy, but also of program interface and of the meaning of “friendship” online. In both cases, many of the privacy issues on Facebook are primarily design issues, which could be ameliorated by an interface that made the flows of information more transparent to users.  相似文献
