The present research investigated whether co-viewer comments in social TV interactions are able to enhance or weaken media effects. With the example of talent shows, the valence of co-viewer comments (pro/contra/none) as well as the type of content (antisocial behavior vs. conventional performance) were varied in an experiment (N = 117). Results showed that participants’ own comments and their private attitudes about the judges varied in line with comment valence. Findings suggest that social TV viewers are prone to social influence of their co-viewers, which might amplify problems regarding the portrayal of antisocial behavior in reality TV.  相似文献

This article examines an informal online community dedicated to The Tudors, a historical television show, and the ways in which its members engaged with a variety of sources in their discussions of the drama’s real-life past. Data were collected over a 5-month period. The analysis included the types of sources used in conversation; members’ purpose for invoking and reaction to sources; as well as topic, participation, and response patterns in the discussion forum. The community is a space in which popular culture and the discipline of history meet. Members come together because of a fictional depiction of the past, yet a desire to corroborate, clarify, contextualize, or uncover what really happened leads users to participate in detective-like inquiry work and the learning of new topics they had not previously considered. Members also challenge and critique one another’s positions and the sources other members invoke in multiple ways, including by using more formal disciplinary heuristics in this informal setting. Key differences emerge in members’ purpose for invoking sources, with popular media used more frequently for illustrating a point or asking a question and nonfiction works most invoked to support and argue historical claims.  相似文献

ABSTRACT

Participation in youth sport is positively associated with physical fitness and performance. The purpose of the current study was to examine if physical fitness measures during childhood and early adolescence predicted high school sport participation. Participants included youth in the Michigan State University Motor Performance Study. Measures consisted of the endurance shuttle run, Wells sit-and-reach, jump and reach, standing long jump, agility shuttle run and 30-yard dash. Individual, generalized estimating equation models were used to estimate the association between each measure and the odds of participating in high school sport. For both sexes, the endurance shuttle run and agility shuttle run were related to sport participation. For boys only, the long jump and 30-yard dash were also associated with sport participation. Better physical fitness and performance across several dimensions in childhood, including those related to motor skills, enhanced the likelihood of sport participation in high school.  相似文献

ABSTRACT

Online learning has become a ubiquitous part of the educational landscape and how teachers are supported in developing approaches to teaching online is a fundamental aspect of the students’ learning experience. Based on the implementation of a professional development course on becoming an online teacher offered in a blended learning mode at one university in Hong Kong, this article proposes that offering this type of professional development in a blended mode is very effective in facilitating enhanced usage of the university’s learning management system. In a blended mode, teachers are actively engaged with blended learning and were found to make more extensive use of features/tools in Blackboard after they attended the professional development course. Results support that offering professional development in a blended mode provides teachers with an authentic student perspective, at the same time as they take guided steps in the teacher’s role in blended learning.  相似文献

This article describes a research project, ‘Improving Learning: The Pupils' Agenda’ (supported by the Nuffield Foundation) in which a team of researchers from Homerton College, Cambridge and the University of Keele, investigated how schools were listening and responding to pupils' perspectives on effective teaching and learning. An account of the project is presented, outlining how the team carried out the investigation and the three themes on which was based. The article goes on to look at the strategies being developed in primary schools, using extracts from the data to illustrate the impact of these strategies in schools. In conclusion it is suggested that the answer to the question posed in the title — can listening and responding to pupils' views give new directions for school improvement — is clearly ‘yes’ and that the advantage of taking this approach lies principally in its potential for improving pupils' attitudes to learning.  相似文献

One hundred and sixty college students read three fictitious biographical passages according to either imagery-mnemonic or no-strategy control instructions. In one mnemonic condition, subjects formed separate images involving each biographical name and its associated facts: in another mnemonic condition, the biographical name and its associated facts were integrated within a single composite image. Relative to an interference-control condition, integrated mnemonic subjects recalled more factual information, whereas separate mnemonic subjects did not. In addition, the recall of integrated mnemonic subjects was statistically no different from that of a noninterference control condition, whereas the recall of separate mnemonic subjects was lower. Both theoretical and educational implications of the results are discussed. The first author’s contribution to this work was supported by an Organized Research Grant from the Graduate School of Illinois State University. The second author’s contribution was supported by the National Institute of Education under Grant No. NIE-G-81-0009 to the Wisconsin Center for Education Research and was facilitated by a Romnes Faculty Fellowship from the Graduate School of the University of Wisconsin, Madison.  相似文献
