变式思维能力是学生数学学习能力的重要表现,数学变式思维是指学生灵活运用已知条件去变式思考.数学学习中的变式思维就是对同一个数学问题,通过变换角度去思考、去探索不同的解题思路的思维方法和学习方式.在平时的数学教学中,我们发现有许多学生做数学习题时,有许多习题课堂上都讲过,但一旦变换习题的条件和数量后,就无从下手.这就是缺乏变式思维造成的. 相似文献

“头脑风暴”在英语教学中的应用突破了定势思维的限制，它虽然不是发散性思维训练的唯一途径．但它在英语教学中的运用的确起到了拓展学生思维的新奇思路的作用。教师在语言教学过程中，对学生进行发散性思维训练，可以为学生提供展示他们创造性思维能力的机会，有助于他们开阔思路，丰富想象，变被动学习为主动学习，改善学习策略，提高学习质量。 相似文献

“带电作业”、“一周一报”、“单一广告”等传统模式制约广播电视报发展,创新发展模式是广播电视报可持续发展的必由选择。当前在选择发展模式的方向和路径上,广播电视报应确立市场取向的发展定位,做新闻、影视、生活兼具的广电报（新都市报）;按市场需要选择出版周期,量力而行向“一周多报”转型;树立多元经营发展思路,拓展广告以外的创收路子;推进“报网融合’’工程,建构数字化、网络化、多媒体信息资源聚合与传播平台。 相似文献

多媒体的传播形态将成为未来人们信息接受的普遍方式，因此，不同发媒介接受行为所形成的思维方式之间就有了相互影响的可能。从电视的角度看，我们可以将网民看成是喜允上网的观众。而网络的运作规则对网民的思维方式产生了潜移默化的影响。长时间上网形成的思维方式，直接影响到他们对电视信息的接受，因此，为了顺应这一趋势，电视传播必须要进行相应的改革。 相似文献

The use of radio for educational purposes in high schools expanded considerably between 1920 and 1970. Education scholars generally qualify radio for schools as a failure. This conclusion is based on the accessibility of radio sets in schools, the interest of teachers in radio for schools, and the budgets allocated for the purchase of radio sets. A wider investigation shows that educational radio resulted from collaboration among school personnel, radio broadcasters and the political authorities. We agree with communication scholars that using a means of communication for educational purposes involves many spheres of society. An examination of the origins, development and decline of radio broadcasting for schools also reveals that this was a technical substitution phenomenon; one means of communication was replaced by another. The use of radio in schools gradually declined, following the introduction of television in schools during the 1960s. Taking all these aspects into account, our study identifies the social mechanisms whereby radio was used for teaching in high schools. This clearly illustrates on a more general level the change in use of audiovisual tools in schools. The Montreal Catholic School Board (CECM) — the largest French‐language school board in Canada — is an institution of particular interest for the study of radio broadcasting for schools. Because of it size, the CECM had sufficient resources and personnel to be a pioneer in education. From 1931, CECM personnel went on the air on CKAC radio to popularize instruction in music, literature and language. Members of Montreal's educational community, parents and students alike, and listeners interested in learning, began to view radio as a means of conveying knowledge. In 1936, Société Radio‐Canada (SRC), the French‐language section of the Canadian Broadcasting Corporation, appeared on the Quebec radio scene, and educational radio gradually became more clearly defined. The programs that were aired, of which the best known was Radio‐Collège, gave the green light to educational radio in francophone Quebec. Before emulating SRC initiatives, the CECM used radio as a tool for social communication. In the early 1950s, the school board used radio mainly as a forum for explaining educational issues to the public; for example, teachers' salary negotiations. From autumn 1950, the CECM School and Family Committee aired a series of ten programs about the role of the school in society. Post‐war Montreal society was in a state of flux. Urbanisation and the emergence of mass communication and consumption were transforming the entire social structure. The francophone elite was starting to question traditional values taught by the Church, and religious practice was declining. Reacting to these new realities, the CECM appealed to parents for their help to ensure that together, family and school would succeed in the task of educating children. The board also used CKAC to discuss the shortage of schools. When parents demanded schools for their children, speakers from the School and Family Committee explained how the problem would be solved. As these examples show, Montreal schools initially made use of radio for social communication. In 1954, following the third congress on the French language in Canada (Troisième congrès de la langue française au Canada), the CECM devised a wide‐ranging campaign to improve the spoken language of students. This was the beginning of educational radio. With the help of executives at CKAC radio, the board created school broadcasting designed to improve everyday language in students from grades 1 to 12. After the first series of programs proved a success, the board repeated the project the following year, broadcasting twice as many lessons. The glory years of Améliorons notre langue parlée would follow, with the series airing continuously from 1954 to 1963. As a result of this enduring venture, the government extended teaching by radio to other school boards across the province of Quebec. This marked the institutionalization of school radio broadcasting. Transistor radios, the democratisation of high school teaching and active pedagogy were all elements that boosted the use of radio in schools. Radio was now present in every classroom, but television was also being introduced. Radio had earned pride of place but was gradually superseded by television. The range of academic subjects widened, and the numbers of hours set aside for television broadcasting increased. Meanwhile, the use of school radio broadcasts gradually diminished. We therefore attribute the decline in radio broadcasting for schools to the emergence of television for schools, in other words, a phenomenon of technical substitution. Finally, our research shows that the contribution by social agents incidental to schools and the influence of various factors external to schools are of major importance in explaining the mechanisms whereby educational radio became part of school life. It shows that radio changed in status from a public communication tool in the 1930s, to a pedagogic tool supporting the teaching of French twenty years later. Our study also shows that radio for schools was created not only by school‐related actors and institutions but also by the mass media and government. Far from being a failure, as education scholars maintain, educational radio was a success, but was replaced by television in the late 1960s. 相似文献
