实验方法是课题实验中极其重要的一个因素，实验方法是否得当，关系到课题实验成功与否。当前，我们在课题实验研究中经常运用的实验方法有：实验研究法、比较研究法、问卷调查法、文献法、个案分析法、经验总结法、测量法、理论研究法、谈话法、自然实验法、行动研究法等。 相似文献

实验引入,指的是运用实验引入新课,它是课堂实验教学的开端。实验引入是物理课堂引入的最主要的方法。笔者在教学实践中主要采用了惊奇现象引入法、黑箱引入法、配合故事引入法、解决实际问题和实验竞赛引入法、实验复习引入法等。这些引入的环节,并不是死板的模式,可以灵活多变地加以应用。 相似文献

在欧姆定律一节之后,安排了伏安法测电阻实验。这个实验在初中物理是一个重要实验。它同测小灯泡功率实验有许多相似之外,对于学生来说弄清了伏安法测电阻实验后,做小灯泡功率实验,可以说是轻车熟路了。 伏安法测电阻实验,课本(P32)画出了常用的外接法,但学习指导书(P63)除外接法之外同时介绍了内接法。图1为外接法,图2为内接法。 相似文献

试析大清律中例的地位和作用 总被引：1，自引：0，他引：1
赫晓惠 《新乡师范高等专科学校学报》2001,15(2):5-7
清代律例合编的法典编纂形式和“有例不用律”的明确规定，使得清例的法律地位大大提高、律的法律地位大为降低。律例合编一度协调了律例矛盾，例对于律的补充、修改、废止作用也曾适应了统治的需要。但是，由于例多为一人一事而设，为贪官污吏徇私枉法留下了很大的空间，导致吏治腐败，加速了清朝的灭亡。 相似文献

What should be learned? How should it be organized for teaching? These seemingly simple questions are deceivingly political. Curriculum theorists are preoccupied with the politics of the first question at the expense of the realpolitik of the second. Instructional designers are preoccupied with the realpolitik of the second question at the expense of the politics of the first. I argue that conceptual distances between curriculum theory and instructional design are based on divisions of labour established during the 1960s. After decades of neglect, curriculum theorists, and specifically critical theorists, appear clueless when it comes to curriculum design and the realpolitik of their causes. When it comes to the realpolitik of practice their political causes are formless. Quite the opposite of critical theorists, instructional theorists nearly mastered the realpolitik of form but have no political causes. I argue that, to contradict the status quo of C&;I, curriculum theorists will have to dirty their hands with the realpolitik of form and instructional designers will have to clutter their heads with theory. 相似文献

文明是劳动的积累和积累的劳动,是人类智慧和汗水的结晶,是人们开创新的历史的既得力量。人类社会的进步取决于人类文明的历史传承与创造,社会个体的价值寓于个体自身在历史发展过程中对人类文明的传承与创造。历史的实现方式在于人们对人类文明的历史传承与创造。英雄人物在历史中的作用取决于其是否融入创造历史的群众运动中去。人类文明的传承与创造是人类历史走向进步的重要基石,也是人类历史得以延续与发展的社会基因。人类文明的历史传承与创造积淀成历史的现实与现实的历史,人类历史的演进与人类文明的传承与创造齐头并进。 相似文献

It is known by entropy theory that image is a source correlated with a certain characteristic of probability. The entropy rate of the source and ? entropy (rate-distortion function theory) are the information content to identify the characteristics of video images, and hence are essentially related with video image compression. They are fundamental theories of great significance to image compression, though impossible to be directly turned into a compression method. Based on the entropy theory and the image compression theory, by the application of the rate-distortion feature mathematical model and Lagrange multipliers to some theoretical problems in the H.264 standard, this paper presents a new the algorithm model of coding rate-distortion. This model is introduced into complete test on the capability of the test model of JM61e (JUT Test Model). The result shows that the speed of coding increases without significant reduction of the rate-distortion performance of the coder. 相似文献

全球化是一个以科学技术的进步为基础、以资本的国际流动和世界市场体系的构建为表征的复杂运动。全球化过程客观上蕴涵着一种世界性全方位整合取向。然而，这种一体化运动却遭到了民族国家这种政治结构形式的抵制。因此，全球化过程中的政治文化呈现为明显的民族性碎裂状态。其原因不仅在于政治文化的民族性，同时还在于各种政治体利益的特殊性。全球化进程的不断展开客观上要求把政治文化的民族性置于全球性政治共识的基础上，从而形成一种以全球性共识为基础的多元政治文化格局。 相似文献

选取“文选学”成立过程当中的关键文学史实作为案例切入,通过系统地分析,如实勾划出六朝隋唐时代文学观念演进的各主要阶段,特别提出中古审美视角转变的三个环节,从而反向论证《文选》和“文选学”正是中古文学观念主要特质的代表。进而将之放在近三百年学术史的坐标上同其它专学的发展作以对比,阐明其美学思想在中国文学史的演进过程中所起的再度深化作用。并在探讨后一子命题的同时,联系传统文献的分类思想,对之进行类型学层面的学术阐释。 相似文献

诗歌意象的组合是诗歌话语的组织。从语言学角度对意象跳跃的成因、定义、存在基础及功能进行分析，诗歌意象出现跳跃是由于话语中缺失某些信息因素之间的确定与被确定关系，而使语义间连贯与衔接的正常状态被破坏而造成，它以话语的语用含义作为它在诗歌中存在的基础，能够起到丰富话语意义的作用。 相似文献

《Educational Philosophy and Theory》2009,41(2):155-165
This paper discusses the most persistent controversial issue that occurred in Western educational philosophy ever since Socrates questioned the Sophists: the role of truth in teaching. Ways of teaching these kinds of controversy issues are briefly considered to isolate their epistemic characteristics, which will enable the interpretation of Plato and Dewey as exemplars of rationalism and empiricism regarding the role of knowledge in the curriculum and thus include their partial truths in the epistemic ethos of teaching. The consideration of pedagogy will then include the partial truths of rationalism and empiricism in the epistemic ethos of teaching by following Kant's 'Concepts without percepts are empty; perceptions without conceptions are blind'.
This claim, however, is narrowed down in two ways compatible with postmodernism and the heavy emphasis on constructionism in faculties of education. After quoting Harry Broudy's statement that the educational epistemic ethos should be domain-specific, guided by the experts' inquiry protocols in each curricular area, it is narrowed down further with Maxine Greene's explication that it should be pluralistic and lesson-specific. This epistemic ethos is not argued as a synthesis but as an aggregate of the partial truths of various epistemologies in the spirit of the postmodern doubt in any one theory of knowledge without throwing out the baby with the dirty bath water.
Finally, the streams of consciousness involved in teaching and learning good knowledge are described phenomenologically to disclose how truth can be disclosed in teaching, thereby grounding propositional knowledge, for example, ontologically in the being of the student and in the being of the world. 相似文献
