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

Not all young children benefit from book exposure in preschool age. It is claimed that the ability to hold information in mind (short-term memory), to ignore distraction (inhibition), and to focus attention and stay focused (sustained attention) may have a moderating effect on children’s reactions to the home literacy environment. In a group of 228 junior kindergarten children with a native Dutch background, with a mean age of 54.29 months (SD = 2.12 months), we explored therefore the relationship between book exposure, cognitive control and early literacy skills. Parents filled in a HLE questionnaire (book sharing frequency and an author recognition checklist as indicator of parental leisure reading habits), and children completed several tests in individual sessions with the researcher (a book-cover recognition test, PPVT, letter knowledge test, the subtests categories and patterns of the SON, and cognitive control measures namely digit span of the KABC, a peg tapping task and sustained attention of the ANT). Main findings were: (1) Children’s storybook knowledge mediated the relationship between home literacy environment and literacy skills. (2) Both vocabulary and letter knowledge were predicted by book exposure. (3) Short-term memory predicted vocabulary over and above book exposure. (4) None of the cognitive control mechanisms moderated the beneficial effects of book exposure.  相似文献

At the Dutch Open university much time is invested in the didactical elaboration of written study materials by the embedding of a large set of ‘embedded support devices’ (objectives, advance organisers, questions, tests, etc.). Is this high investment in the design of written study materials for use in the distance education setting worth the effort? To answer this question, we focused in this research on the actual use of these embedded support devices (ESD) by Open university students. After elaborating a theoretical model that was helpful to derive hypothetical functions and effects of a large set of ESD, quantitative and qualitative hypotheses were put forward in relation to the actual use of a subset of ESD that was implemented in a law course. The research set‐up was based on an in‐depth analysis of responses to structured interviews. Analysis of the results indicate that students make large use of ESD; nearly all ESD are used by more than 60% of the students. Furthermore, students make deep level use of the ESD. Moreover, interrelations could be detected between general student characteristics and deep level use of ESD. Women seem to be more likely to use planning ESD, orientating ESD and processing ESD at a deep level. Students with higher prior education levels seem to use ESD at deep level to a greater extent. Students with less prior knowledge of governmental law and students using study guidance use testing ESD more at a deep level.

No interrelations were detected between cognitive student characteristics and the use of ESD.

To get a better view of the ‘type’ of students using ESD, the interrelations between general student characteristics have been analysed. Especially higher educated (and intrinsic motivated) female students with a lot of study experience and less prior knowledge make deep level use of ESD. When linking the use of ESD to study success, it could be stated that students using ESD at a deep level are not only more likely to have a higher score on the examination, they also need fewer examination attempts. Comparing theoretical and spontaneously mentioned functions and effects of ESD revealed that students indicate functions that are not theoretically expected. Students seem to ascribe their own functions and effects to ESD.

The main conclusion of this research is that the high investment in the design of written study materials is worth the effort; but that it is important to take account of student characteristics when implementing ESD in course materials. It can, for instance, be argued it is desirable to incorporate into the materials ‘training’ about the use of the ESD. Moreover, these results link up with the growing tendency to develop more flexible Ou‐courses that are adaptable to individual student needs. The latter implies that the production of written versions of the study materials is to be redirected towards the development of automated interactive learning environments.  相似文献

Three field studies tested the hypothesis that anticipating a graded test as opposed to a pass-fail test enhances metacognitive monitoring. Participants were teacher candidates who completed a mid-term and a final test in psychology courses. Each participant chose whether the result of the final test should be evaluated with one of five grades or with a pass-fail decision. In both tests, participants answered true–false inference items about the contents of the course and indicated their confidence in the correctness of each answer. When a graded test was expected, confidence and the absolute accuracy of the confidence judgments increased and bias decreased to a greater extent than when a pass-fail decision was expected. However, expecting a grade increased participants’ confidence not only in correct answers but also in incorrect answers (Study 1). Feedback and instructions emphasizing the importance of accurate discrimination between correct and incorrect answers did not weaken this effect (Study 2). The generalizability of the findings was investigated by reanalyzing the test results of participants in eight other psychology courses (Study 3). The results are discussed in terms of the motivational consequences of grading.  相似文献

This study examined how hybrid documentary formats, which embed educational contents into narratives, are cognitively processed. Based on existing research and theories, two reception modes were identified: processing with a focus on the narrative plotline and processing with a focus on the thematic structure. In two experiments, two markers of narrative processing could be found for hybrid television documentaries: the experience of transportation and the narrative distance effect. In the first experiment, it could be shown that re-enactments and personal variables enhance the experience of transportation. The second experiment confirmed the narrative distance effect, which occurs independently of reception goals. This means that educational facts which are closely tied to the narrative plotline were learned better than distant facts, regardless of whether the recipients watched the documentary for information or entertainment purposes. The study supplements prior theories on hybrid processing and provides conditions under which narratives are appropriate for learning.  相似文献

New Public Management and bureaucratic models fail to acknowledge the value of peer-to-peer cooperation between citizens as a resource for public service support. Social media enable citizens to create environments for sharing information about public services in Communities of Public Service Support. The success of this model for public service support depends on the availability of communities, the level of active participation, and the information content. This paper presents an empirical study of virtual communities of expats in The Netherlands. Our analysis shows that there is a wide variety of virtual expat communities with a high level of participation and valuable content. We conclude that virtual communities play an important role in public service support since they facilitate social learning between citizens.  相似文献

This study was concerned with identifying prerequisites for the successful use of videos that offer different levels of interactivity. In a homework scenario, 64 ninth graders participated either in a search training demonstrating the efficient use of features facilitating the selection of relevant information or in a control training focusing on the integration of new information with prior knowledge. Following the training, the participants used either a common video that allowed them to control the transient flow of the information via stop and browsing or an enhanced video that additionally facilitated the localization of information via chapter selection and an index. Overall, the students wrote two essays (Essay 1: summary; Essay 2: argument) and performed a search task. The study revealed that, independent of the training condition, students benefitted from the enhanced video for the search task which merely required naming isolated facts. Moreover, in a summary task, the enhanced video resulted in the consideration of information from more different chapters when the task required gathering information from the video; however, this broader consideration of chapters only translated into naming more information after the search training. The data of a second essay requiring inferences about the video’s contents (argument) were not analyzed due to a floor effect. Taken together, these results indicate that the characteristics of a task as well as the students’ knowledge of respective search strategies need to be considered when implementing interactive features in video environments.  相似文献

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
