物理是一门以实验为基础的自然科学,而多媒体模拟实验则是在真实物理实验基础上的虚拟再现。虽然多媒体模拟实验教学克服了器材实验教学的许多弊端,给物理实验教学带来了极大的方便,但我们在物理实验教学中不能仅依靠多媒体模拟实验,而不亲自做实验。否则,就会给学生不真实的错觉。多媒体模拟技术应该用于弥补物理器材实验过程中的不足,而不应该盲目模拟。所以,只有实现物理器材实验与多媒体模拟实验的优势互补,才能充分发挥作用,相得益彰。 相似文献

物理是一门以观察、实验为基础的自然科学,物理规律都是在观察和实验的基础上,认真总结和思考得来的.作为一名物理教师,在物理知识教学过程中,如能正确地演示和指导学生实验,不仅能激发学生求知欲望,促进学生掌握知识、运用知识,还可以培养学生严谨求实的科学态度,所以实验教学能很好地实现"三维"目标. 相似文献

初中物理是一门实验学科,如果离开实验,物理将变得没有根据,社会也就会停止运行。所以重视物理就必须重视物理实验。但是当前初中物理教学中,升学压力和其他方面的社会压力,导致很多学校忽视了物理实验教学。"新课标"明确要求将物理实验规划到考试内容后,一些学校才开始重视物理实验教学。 相似文献

<正>物理学是一门以实验为基础的自然学科。在物理学发展史中,每个物理概念的建立,每个物理定律的发现,都有坚实的实验基础。法拉第为了找出"磁生电",历经十多年,做了无数个实验,终于找到了"磁生电"的规律。可以说,离开了物理实验,就没有物理学的发展。物理实验作为物理教学的基本手段,有其特殊的教学功 相似文献

物理学是一门实验科学。在物理学中,每个概念的建立、每个定律的发现,都有其坚定的实验基础。物理实验是物理课程内容之一,物理实验教学应是物理教学的重中之重。但在现实高中物理教学中,物理实验教学现状与新课改要求还有差距,"重理论、轻实践;重分数、轻能力;重结论、轻过程"的现象普遍存在。如何解决这个问题,本文从建构主义理论和新课程理念出发,结合实例简述让物理实验回归到物理探索中去的意义和方法。 相似文献

How do children solve force and motion problems in computer simulations without explicit knowledge of the underlying physics? This question was addressed by saving the keystroke input of 19 sixth-grade children in computer memory as each interacted with a simulated, frictionless object using Logo turtle-graphics. The keystroke sequences were first used to determine subject performance on the gamelike features of the simulation. A second analysis used the Newtonian structure of the program to investigate alternative methods for controlling turtle velocity. Five boys and five girls were interviewed during the simulation concerning the perceived relationship between keyboard input and turtle behavior. Subjects who could clearly state some keyboard effects did not score high on either computer analysis, yet achieved the most general solutions of the computer problem. They did so by exploring turtle behavior under a greater variety of conditions than the subjects who achieved partial solutions. For the successful subjects, the turtle was related by analogy to useful information from existing conceptions of motion. 相似文献

In the last fifteen years a small group of European physicists has been working towards an approach to physics education based on the actual practices of physics research. The standard presentation through traditional textbooks plus didactic laboratory is rejected, and instead case studies contributing and borrowing from contemporary history, philosophy and sociology of science are provided. Analysis of original papers, scientific debates, institutional settings are often accompanied by reconstructions of important historical instruments. The resulting interplay between theories, instruments and experimental results offers a view of physics fascinating and entertaining, closer to the actual scientists' activities, deprived of many traditional ideological assumptions, open to the students interpretations and often in tune with contemporary findings of science educators. The group's activities are quietly flourishing, have acquired institutional recognition in the European Physical Society, and are now coordinated with the ones organized around the journal Science & Education and the International History, Philosophy and Science Teaching Group. 相似文献

At this time big and important transformations of the social system are taking place in my country. In consequence of this process, practically all concepts, notions, traditions and criteria are changing. So Slovak society is in need of new ideas. Undoubtedly, history may become a source of such ideas. One can expect this for the history of physics in Slovakia too. 相似文献

Electromagnetic fields carry not only energy and momentum but also angular momentum. The angular momentum of the field can
lead to some curious results like the one which is described here.

One of the celebrated results in black hole physics is that black holes have a temperature and they emit a thermal spectrum
of radiation. Though a rigorous derivation of this result requires quantum field theory, a flavour of the essential ideas
can be provided at an elementary level as indicated here.

The idealized flow of fluid around a spherical body is a classic textbook problem in fluid mechanics. Interestingly enough,
it leads to some curious twists and turns and conceptual conundrums.

Gender gaps in physics in favour of boys are more prominent in Israel than in other countries. The main research question is to find out what gender issues are at play in Israeli advanced placement physics classes. Matriculation exam scores from approximately 400 high schools were analysed across 12 years. In addition, semi-constructed interviews were conducted with 50 advanced placement physics students (25 girls and 25 boys). In terms of participation, it was found that the ratio of girls to boys has been unchanged from 1988 to 2000 and is roughly 1:3. In terms of performance, it was found that the final matriculation scores of boys and girls are similar. However, breaking up the final scores into its two components - teachers' given grades and matriculation test scores - showed that boy's test scores are usually higher than girls' test scores, while girls' teachers' given grades are usually higher than boys'. Results from semi-constructed interviews pointed to two factors that are especially unfavourable to many girls: excessive competitiveness and lack of teaching for understanding. Girls' yearning for deep understanding is seen as a form of questing for connected knowledge. It is suggested that instructional methods that foster students' understanding while decreasing competitiveness in physics classes might contribute to girls' participation and performance in advanced physics classes while also supporting the learning of many boys. 相似文献

The Coulomb problem, which corresponds to motion in a potential that varies as r
−1, has a peculiar symmetry which leads to a phenomenon known as ‘accidental’ degeneracy. This curious feature exists both in
the classical and quantum domain and is best understood by studying a more general potential and obtaining the Coulomb problem
as a limiting case. 相似文献
