Summary The objectives of this study were to examine (1) the relative effectiveness of closed-circuit television for classroom teaching compared to conventional teaching and (2) the acceptability of closed-circuit television teaching to the students. A course was offered both by closed-circuit television and by conventional teaching. Students within each group were asked to rate the course and other related concepts. In addition, their examination grades were obtained. No differences were found with respect to performance. The students taught via television rated the course and their instructors relatively lower than those who received conventional instruction. Howard M. Bobren is assistant to the director, Institute of Communications Research and Sheldon L. Siegel is research assistant, College of Education, both at the University of Illinois.  相似文献

近年来历史的影像化书写,已构成了一种不容忽视的文化景观。这一现象的产生除了我国独特的文化传统及影视创作传统外,还与当今大众的接受心理以及创作者受商业利益的驱动密不可分。这些影视历史剧固然繁荣了当代影视艺术的创作,但存在的问题必须引起我们的高度重视。  相似文献

作为中国电视业的重要组成部分,地市级电视媒体如何应对加入WTO后所带来的机遇和挑战。这既是一个理论问题,更是一个实际问题,曾为中国电视业的繁荣和发展作出过重大贡献的地市级电视媒体,随着信息时代的到来,就陷入新闻受众流失、录播设备老化、广告收入锐减、专业人才匮乏的困境中;加入WTO后,WTO的协定制度又将给它的生存和发展设置种种关卡。所以,绝大部分地市级电视媒体将圆满地完成其阶段性的光荣使命,按照“强者更强,适者生存”的发展原则,自行融入到新的发展进程中,或被撤销,或进行集团整合。这样才有利于整个中国电视业主动应对挑战,赢得新的发展机遇。  相似文献

It is often thought that bookwork is likely to be hampered by an accompaniment of television, or more simply of music. Others allege that television reduces the time that is spent with books or writing. It is helpful, therefore, to use a very large survey sample to find out how many people do perform intellectual homework, and how many of these do so with television (or musical) accompaniment. It is clear that doing homework, and doing so with television or musical accompaniment, is a widespread experience, especially among young teenagers. Several statements outlining possible advantages or disadvantages were put to respondents, to record their agreement or disagreement. There was no overwhelming endorsement of disadvantages of an information‐noisy work environment, especially among young teenagers. There is substantial evidence that people believe that the possible competition for one's attention from television or music distracts other potentially disturbing individuals, or that it can act as a kind of ‘sensory screen’.  相似文献

自20世纪60年代以来,教育电视凭借其传递信息量大、传输质量高、视听效果好等优势占据了我国教育领域主流传播媒体的位置。但近年来随着快速、便捷、信息量大、双向互动、直观形象的网络多媒体传播技术的迅速崛起和广泛普及,教育电视面临着严重的挑战。网络时代教育电视有无存在的必要和价值以及未来教育电视应如何发展,一度成为该领域关注的焦点。针对此问题,本文首先从媒体发展的历史、教育电视媒介和网络媒介的发展现状及其优势对比三个角度分析了网络时代教育电视将长期存在的必然性,并在此基础上,详尽阐述了教育电视和网络媒介相融合发展的意义和作用、内容以及形式。  相似文献

广播电视语言在很大程度上接近日常口语,应定位于“说话”的形式上。这是多元化社会发展的需求,也是广播电视自身发展规律的需求。但是要“说好话”必须受众的语言需求及电视节目主持人,用意员自身素质两个方面加以要求。  相似文献

Interactions between two pairs of subjects were conducted face‐to‐face and over a two‐way closed‐circuit television medium and were tape recorded. The speech for each subject over each medium was edited to remove silent intervals and the resulting edited speech segments, each about 1 minute in duration, were analyzed by a computer implementation of the cepstrum method of fundamental‐frequency determination. The speech of all four subjects showed a statistically significant rise in fundamental frequency ranging from 3.89% to 7.83% for the closed‐circuit television condition relative to the face‐to‐face condition. This result could imply that two‐way closed‐circuit television is a more tense or stressful medium than face‐to‐face communication. Alternatively, the effect could be explained by such other factors as a rise in speech level caused by a greater perceived distance between the participants in the closed‐circuit television condition.  相似文献

电视媒体必须与时俱进,不断寻求新闻表现和传播形式上的创新和突破,以实现最佳宣传效果。各级电视台已开始大量“正在发生的事实的报道”的形式进行动态新闻的现场报道;而“正在报道发生的事实”也已经成为有条件的电视台对直播即将发生的重大新闻事件的必备手段。  相似文献

媒介技术变迁为儿童的同伴关系重新设定框架。在印刷术大量应用前,儿童间同质性较高。印刷术的发明使得大规模公共教育成为可能,在学校里儿童获得了在各种规则下与同伴相处的能力,形成了新的互动惯习。电视的出现既导致儿童同伴关系的相对疏离,又促进了儿童同伴亚文化的形成。网络为儿童提供了获取同伴关系的新型方式,扩充了儿童与同伴的交流模式。手机的技术特征使得儿童在同伴关系中"永远在线",扩大了儿童的私人空间。  相似文献
