To what extent do students and teachers hold similar beliefs about excellent teaching? Do differences in beliefs have practical implications (e.g., how students rate their teachers on end-of-semester evaluation forms)? In Study 1, undergraduate students (N=414) and faculty members (N=128) responded to questionnaires assessing their perceptions of an excellent discussion leader, lecturer, or instructor. Participants judged items that contributed to a Structure composite as more characteristic of excellent lecturers than excellent discussion leaders and items that contributed to a Process composite as more characteristic of excellent discussion leaders than excellent lecturers. Results for students and teachers showed several systematic differences. In Study 2,278 students and their course teachers rated the characteristics of a hypothetical excellent lecturer. In addition, students rated the effectiveness of their individual teachers. Students’ ratings of their teachers were higher when students and teachers agreed on their perceptions of characteristics of excellent lecturers. 相似文献

In general, rhetoric and myth play important roles in policymaking. Myths may inspire collective action but may also mystify and blur views on reality. In this article we identify, analyze, and reflect on the myths underlying the e-government programs of Australia, Canada, the United Kingdom, Denmark, and the Netherlands. We found that in all national policies myths of technological inevitability, a new and better government, rational information planning, and empowerment of the intelligent citizen can be discerned. Although the mobilizing powers of these myths are acknowledged, we conclude that existing empirical studies have generated little support for the inescapable telos of these myths, which makes canvas cleaning effects of e-government initiatives less likely. 相似文献

Exploration and exploitation in innovation systems: The case of pharmaceutical biotechnology 总被引:2,自引:0,他引:2
This paper develops a theoretical framework for an explanation of how exploitation and exploration build on each other, in a ‘cycle of discovery’, developed in earlier research. The framework is tested empirically, in the sense of seeing whether it can help to reconstruct and understand the emergence of the pharmaceutical industry. One of the conclusions is that whereas recent literature stresses the idiosyncratic nature of the biotechnological revolution, our analysis seems to reveal that this does not seem to be as unique as suggested. From this, we conclude that the theoretical framework we propose, serves its purpose of explanation. But there are also some lessons for improving it. 相似文献

Analytic Frameworks for Assessing Dialogic Argumentation in Online Learning Environments 总被引:3,自引:2,他引:1
Douglas B. Clark Victor Sampson Armin Weinberger Gijsbert Erkens 《Educational Psychology Review》2007,19(3):343-374
Over the last decade, researchers have developed sophisticated online learning environments to support students engaging in
dialogic argumentation. This review examines five categories of analytic frameworks for measuring participant interactions
within these environments focusing on (1) formal argumentation structure, (2) conceptual quality, (3) nature and function
of contributions within the dialogue, (4) epistemic nature of reasoning, and (5) argumentation sequences and interaction patterns.
Ultimately, the review underscores the diversity of theoretical perspectives represented within this research, the nature
of dialogic interaction within these environments, the importance of clearly specifying theoretical and environmental commitments
throughout the process of developing or adopting an analytic framework, and the role of analytic frameworks in the future
development of online learning environments for argumentation.

Income is not enough: incorporating material hardship into models of income associations with parenting and child development 总被引:2,自引:0,他引:2
Although research has clearly established that low family income has negative impacts on children's cognitive skills and social-emotional competence, less often is a family's experience of material hardship considered. Using the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (N=21,255), this study examined dual components of family income and material hardship along with parent mediators of stress, positive parenting, and investment as predictors of 6-year-old children's cognitive skills and social-emotional competence. Support was found for a model that identified unique parent-mediated paths from income to cognitive skills and from income and material hardship to social-emotional competence. The findings have implications for future study of family income and child development and for identification of promising targets for policy intervention. 相似文献

本演讲探讨了欧洲早期艺复兴期间(大约1350—1700)为解读亚里士多德的(修辞学)中的论述所做出的努力,讨论了欧洲的注释在理解亚里士多德的(修辞学〉中所遇到的困难,关注了当时学意料之外的某些论争,并力图阐释引起这些论争的原因。作认为,人们力图阐释关于一种化的论述并力图从另一种化的需求和兴趣来解读这种论述的努力对中美两国具有重要意义,这些阐释所可能引发的结果也具有积极意义。作的这种解读对当今世界——对中国和“西方”国家富有更为广泛的意义——因为他在试图解读产生于一种化而被转译到另一种化的修辞学和传播学理论。作指出,在欧洲艺复兴时期,人们相信修辞学和社会很大程度上是一回事。修辞学能够使人们避免暴力、摆脱兽性,使许多不同人的思想统一起来,促成一种包容各种矛盾的和谐社会。修辞学使我们变得明。[第一段] 相似文献

This paper focuses on seven major managerial practices and three negative conditions that must be managed to enhance employee growth and development. These managerial practices and conditions have significant potential for human resource development practitioners and performance improvement technologists by providing new perspectives to improve employee performance through employee growth and development activities. Surveys measuring employee perceptions of manager behaviors were administered to 503 MBA and PhD students from the United States, resulting in 463 useable responses. The hypotheses were tested using linear regression and structural equation modeling. Based on the analysis, the researchers found that involving employees in decision making, motivating employees, treating employees as unique individuals, and making certain that managers are effective have the highest influence on employee growth and development. 相似文献
