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

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

德语中有关教育作用的理解如“文化构建（教养）”（Bildung）和“培训”（Ausbildung）的区分在以技术飞速发展为标志的未来不再有效。不管人们如何理解教育,教育的首要目标必须是培养思考的能力、提出新观点的能力以及共同实施这些观点的能力。认知上的多语主义是防止知识专业化的唯一手段,这种知识专业化会大大限制我们的视野,从而导致结构上的不负责任。 相似文献

The present study examines how learnersinteract with one another within the context ofa computer conference for the purposes ofpassing a test. In a faked computer conferencewith predetermined messages, both the number ofmessages irrelevant to the topic, and theexplicit threading of messages were varied in a2 × 2 design (n = 54). Subjects participated in anasynchronous fashion over a course of fourlog-in sessions. In general, learners indicateda fairly consistent pattern of reception. Theyopened virtually all messages, grouped them ina non-chronological order, and processed themaccording to their topic relevance. Thispattern was also mediated by the conferencecharacteristics. Explicit threading led tosequences of message readings that were morecontent oriented. Similarly, fewer irrelevantmessages lead to prolonged reading times ofrelevant messages. Whereas learning success wasnot affected by conference characteristics,explicitly threaded messages decreased theperceived cognitive demands. 相似文献

In this article, the potentials of advanced technologies for learning in science exhibitions are outlined. For this purpose, we conceptualize science exhibitions as dynamic information space for knowledge building which includes three pathways of knowledge communication. This article centers on the second pathway, that is, knowledge communication among visitors. We argue that advanced technologies have specific potentials to support all forms of visitor-to-visitor knowledge communication and, furthermore, allow for new forms of knowledge communication among unacquainted visitors and beyond the actual museum visit. We discuss mechanisms of collaborative learning with regard to their relevance for visitor-to-visitor knowledge communication and present prototypical advanced media applications in science exhibitions that address these mechanisms. This article both contributes to our understanding of collaborative learning in science exhibitions and the support advanced technologies can provide for visitor-to-visitor knowledge communication in science exhibitions. 相似文献

In the present experiment the animation of the operating mechanism of a pendulum clock was used in order to compare the effects of spatial cueing with those of temporal scaling on the comprehension of the animation. The presentation speed of the clock mechanism (normal vs. fast) and signalling cues to three different parts of the mechanism (weight, pendulum, and an irrelevant gear as blinking elements) were used in a 2 × 3 between subjects design with 144 participants. It was found that compared to normal speed condition, understanding was improved in the fast speed condition, but was unaffected by any of the cueing conditions. The results indicate that, although guidance of attention to relevant parts of an animation is often seen as a key to effective instructional design, the way temporal manipulations affect understanding is independent from local attention guiding. 相似文献

This paper summarizes biophysical and bioengineering studies of biological hazards which may result from exposure to microwaves. Various phases of this study include: determination of the electrical characteristics of body tissues; determination of microwave and membrane characteristics; studies of a variety of electromechanical phenomena which can be evoked by RF fields; investigations of the mode of propagation of microwaves into man and animals, including absorption and reflectance characteristics and radar cross-section of man. One outcome of this work is a standard of safe exposure which is presently accepted in most Western countries. 相似文献

Two complementary studies, one in the laboratory and one in the field, compared the usage patterns and the effectiveness of interactive videos and illustrated textbooks when German secondary school students learned complex content. For this purpose, two videos affording different degrees of interactivity and a content-equivalent illustrated textbook were used. Both studies showed that in contrast to previous studies working with non-interactive videos, the effectiveness of interactive videos was at least comparable to that of print, probably due to the possibilities provided for self-regulated information processing. It was shown that the interactive features of the videos were used spontaneously. However, features enabling micro-level activities, such as stopping the video or browsing, seemed to be more beneficial for learning than features enabling macro-level activities, such as referring to a table of contents or an index. This finding is explained by students’ misconceptions about the use of features enabling macro-level activities. 相似文献
