Before,During, and After Examination: Development of Prospective Preschool Teachers’ Mathematics-Related Enjoyment and Self-Efficacy     

Sigrid Blömeke  Oliver Thiel  Lars Jenßen 《Scandinavian Journal of Educational Research》2019,63(4):506-519

This article examines the stability of Norwegian prospective preschool teachers’ enjoyment of mathematics and their mathematics-related self-efficacy before, during, and after a teacher-education examination. In addition, the stability of the two constructs across countries was examined through a comparison with Germany. The data revealed partial stability (technically speaking, metric invariance) of enjoyment but not of self-efficacy. Self-efficacy increased significantly before and after the examination without decreasing enjoyment, which may be a result of increased learning time. Prior mathematical knowledge predicted the level and development of enjoyment and self-efficacy in both countries. Many Norwegian students reported low mathematics-related enjoyment and self-efficacy, including negative developments. It may be important to provide positive experiences of mathematical activities during preschool teacher education.  相似文献   

Discrimination and generalization of leaf damage by blue jays (Cyanocitta cristata)     

Pamela G. Real  Ruth Iannazzi  Alan C. Kamil  Bernd Heinrich 《Learning & behavior》1984,12(2):202-208

Blue jays (Cyanocitta cristata) responded to projected black-and-white silhouettes of cherry leaves that were either undamaged or were damaged by either cryptic caterpillars that disguise leaf damage due to their feeding or by noncryptic caterpillars that do not disguise leaf damage due to their feeding. Pecks to the key on which the images were projected were reinforced only if interresponse times fell within specified temporal boundaries. These boundaries were different in the presence of the two types of leaf damage. Following training with one exemplar of each damage type, the jays correctly categorized novel instances of both types. They categorized novel undamaged leaves as if they were examples of leaves showing damage by cryptic caterpillars. Results suggest that the jays can readily discriminate and generalize to new members of a polymorphous stimulus class. The results suggest that techniques for the study of concept formation in animals can be applied to an animal’s ability to categorize stimuli that are involved in a potential prey-predator relationship.  相似文献   

Stichwort: Bildungsökonomie und Qualität der Schulbildung     

Manfred Weiß 《Zeitschrift für Erziehungswissenschaft》2008,11(2):168-182

Keyword: Education Economics and Quality of Schooling. With reference to an earlier keyword article from the same author, this contribution looks at recent developments in education economics. The focus is a critical review of the field‘s contribution to research on the necessary conditions for high quality schooling. Of particular interest at the moment are the institutional framework conditions in a school system, which set incentives for performance. These are judged to be better than resource-based strategies of quality assurance. The empirical basis is provided by estimates of production functions using data from international school performance studies. This article will point out the limited validity of evidence gained through these studies and the – in sum – contradictory empirical findings. For this reason, political recommendations on the basis of this approach should be more reserved.  相似文献   

Media Logic and Political Logic Online and Offline     

Jörg Haßler 《Journalism Practice》2014,8(3):326-341

One aspect of the mediatization of politics is the idea that political actors adapt to the communication logic of news media to gain, for example, news media attention. Currently, this process may be influenced by the diffusion of the internet as a political communication channel, especially because online communication provides a new opportunity for political actors to communicate directly with citizens. Thus far, the adaptation to media logic by political parties has mainly been examined in the context of election campaigns. In order to transfer these findings to regular political communication, this study compares the use of media logic in the mass media and in direct political communication channels online and offline about the United Nations Climate Change Conferences 2011 and 2012. A quantitative content analysis of the conference protocols (input) and the presentation of the conference results in the seven most frequently used German offline news outlets (print and TV) and their online counterparts, as well as political offline and online communication channels like parliamentary speeches and websites of the six parties represented in the German parliament (output), was conducted. Results show that in the context of regular political communication, political actors seem to follow media logic to a lesser extent than in the context of election campaigns. Thus far, the influence of online communication on the mediatization of politics seems to be rather marginal. The causes and consequences of these findings are discussed.  相似文献

Cognitive preconditions of early reading and spelling: a latent-variable approach with longitudinal data     

Anna-Lena Preßler  Tanja Könen  Marcus Hasselhorn  Kristin Krajewski 《Reading and writing》2014,27(2):383-406

The aim of the present study was to empirically disentangle the interdependencies of the impact of nonverbal intelligence, working memory capacities, and phonological processing skills on early reading decoding and spelling within a latent variable approach. In a sample of 127 children, these cognitive preconditions were assessed before the onset of formal education, whereas reading as well as spelling achievement was measured at the end of grade 1. The findings indicate that working memory does contribute to the prediction of early reading and spelling, and that this contribution outperforms that of general intelligence and phonological recoding from long-term memory during the early steps of reading and spelling acquisition. Moreover, the results show that phonological awareness mediates the effects of working memory capacities on early literacy outcomes. The role of working memory and phonological awareness as key cognitive preconditions of early reading and spelling are discussed.  相似文献   

The Internet's Impact on Content Utilization Chains: An Exploratory Case Study on Leading Publishers in Germany     

Bernd Schulze  Thomas Hess  Bernd Eggers 《媒体管理杂志》2013,15(1-2):12-22

The market-side utilization of content is affected by the prevalence of the Internet. However, it is not clear in this context how and to what extent it has changed in detail. Aiming to reveal and evaluate the Internet's impact in the print media industries, we examine the latest enhancement of publishers' content utilization chains. For this purpose, we conduct an exploratory case study and apply time-series analysis as well as cross-case synthesis to analyze the data collected. As unit of analysis, we focus on 3 publishers whose content utilization practices represent best practice in the German newspaper, magazine, and book publishing industries, respectively. Based on the results of the case study, we conclude that the Internet has an impact on the composition of publishers' content utilization chains but to a varying extent. However, because Internet-based content utilization windows hardly generate extra revenues or cannibalize existing ones, publishers' revenue models have not changed significantly so far. Besides, we state that the arrangement of Internet-based content utilization windows, which mostly constitute direct-channel distribution, decisively depends on their relation with print-based ones. Hence, we are able to show that the Internet's impact on publishers' content utilization chains manifests itself in various ways.  相似文献   

The Bertelsmann AG: An Exploratory Case Study on Synergy Management in a Globally Acting Media Organization     

Bernd Schulze  Bodo Thielmann  Stephan Sieprath  Thomas Hess 《媒体管理杂志》2013,15(3-4):138-147

By the multiple usage of immaterial resources across organizational and national market borders, globally acting media conglomerates are able to achieve outstanding synergies. For this reason, they are expected to realize higher margins of profit than smaller-size, nondiversified media firms. However, no empirical evidence has been found for a positive correlation between a firm's size or its presence in many businesses of the media industry and its economic performance until now. Consequently, possible synergies do not seem to be fully exploited in many cases. This article analyzes how to institutionalize and implement synergy management in decentralized media organizations. For these purposes, we first develop a basic understanding and then conduct an exploratory case study on Bertelsmann's approach, which overcomes the stress ratio between corporate coordination and independent action at the operational level. Distinguishing various product types and triggers, this case study renders the process of synergy management more precisely and illustrates how to arrange responsibilities between organizational units. Finally, by relating the results of the case study to the body of literature, we work out patterns of responsibility assignment and drivers of success for strategic integration. In contrast to operational integration, the latter may lead to synergies due to cross-divisional cooperation and business development.  相似文献
