我们老师习惯地认为计算教学是教学中最枯燥、乏味的课程。在实际的计算课堂中,也只重视计算的结果,不重视计算法则的形成过程和计算方法的概括。认为计算中的算理讲不清,说不明．所以在公开课的教学中,也很少看见计算教学的身影。 相似文献

计算是小学数学的基本内容.让学生掌握正确的计算方法,养成良好的计算习惯是提高计算正确率的有效方法.教师应该让学生在情境中理解算义,在探究中明确算理,在练习中运用方法,在实践中养成习惯,多方位的推进计算教学,这样学生才能掌握好计算. 相似文献

计算教学在小学数学教学中有着非常重要的地位,计算能力也是学生必须具备的一种基本能力。在实际教学中,学生计算错误率偏高,不少学生的计算速度偏慢。那么,如何切实提高计算教学的有效性,使计算教学达到高效低耗呢?笔者认为应做到以下几点。一、计算教学要与问题解决相结合计算是由于解决生活中实际问题的需要而产生的。而传统的计算教学却没有将它同生活实际问题联系起来,枯 相似文献

正小学数学教学是学生认识数学、学习数学的起步阶段。在这个阶段中计算能力的提高是非常重要的。计算是学好数学的基础,数学中一切问题都需要通过计算来解决。因此,在小学数学教学阶段提高学生的计算能力是我们的教学重点。计算能力的提高包括速度上和质量上。我们在教学过程中要潜移默化地培养学生的计算能力。首先要从培养学生良好的计算习惯入手,从一点一滴做起逐步提高学生的计算能力。下面是笔者在实际教学中对提高学生计算能力的一些做法,现总 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

理本论是朱熹哲学思想的核心和最高范畴,也是朱熹整个学术思想的核心和理论基础。这是一个具有客观唯心主义性质和伦理本位色彩的哲学范畴。其本体论哲学的构建是通过对传统文化中儒、道、佛三家思想的全面吸收和改造而完成的。具体讲:吸收佛学本体论的思维模式并将之改造为道德本体论;吸收儒学的道德学说并将之改造为伦理本位的哲学:吸收道家的认识论思想并将之改造为伦理体验的认识论。 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

A range of sociological work has theorized neoliberal regulative regimes, suggesting the contradictions contained in the enactment of policy and foregrounding the painful effects of these processes on subjectivities produced within performative school cultures. This paper contributes to this body of work by tracing the movement of desire in teaching assistants’ subjective relations to workplace practices of remuneration. We do this through an analysis of a series of group- and individual-free associative interviews with teaching assistants working in primary schools. Drawing on a Lacanian account of the way processes of identification channel affect, as desire, through signifying chains within a discursive field, we explore the associative chains of meaning that overdetermine the subjectivities produced within performative practices of remuneration. We suggest that the complex and contradictory chains of signification embodied in the school environment constitute a space where fragile teaching assistant subjectivities reiterate previous relations to an ambiguous Other. 相似文献

This article explores the question: Why are students of worth? Educationally, an answer often involves a Kantian response:
They are of worth because they are always ends and never means. This response is usually connected to a notion of autonomy
interpreted as individual, rational self-determination. The article argues for a different answer. The essay begins with a
recent educational example of construing worth as rational autonomy. Meira Levinson, in her book The Demands of Liberal Education (1999), argues for a version of rational autonomy which is taken in the essay as a Kantian response to the question. The
essay then turns to Kant’s own understanding of intrinsic human worth as ends. Although the essay agrees in general with the
notion of end, it criticizes Kant’s version of rational autonomy. Instead, it argues for a notion of worth as irreplaceable
singularity. Both the critique of the Kantian answer and theessay’salternative are shaped by the philosophy of Emmanuel Levinas.
Here technical notions of “the other,” proximity and singularity are brought to bear on the question of human worth. The Levinasian
alternative, so the essay argues, better answers the question of student worth by highlighting the incomparability of the
student as a singular other. 相似文献

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

The paper is a critique of the dominant model of applied philosophy. As currently structured, courses in applied philosophy are a response of philosophy departments to administrative demands to increase enrollment units. In order to achieve this goal, the properly philosophical approach to matters of concrete social concern is dropped in favour of decontextualized, ahistorical, and uncritical applications of philosophical theories to immediate practical problems. Using the example of applied ethics, I argue that the key problem besetting current trends in applied philosophy is that they all fail to uncover the contradiction between given social regimes of value and the universal concepts which must be employed to legitimate those regimes. While it is an essential duty of philosophy to be relevant to the practical issues of the day, it must be relevant on philosophical terms. That is, the real application of philosophy to social problems is not the unthinking mapping of a particular philosophical theory onto a problem, but bringing to light the hidden value assumptions definitive of different societies, and shaking to the foundation their claims to legitimacy. I spell out this alternative approach to applied philosophy through an example drawn from my own teaching practice. 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
