培养小学生数学“品读”能力的实践探索

数学中的“品读”,其实是阅读,它是学生获取数学知识的重要手段。在数学教学中,教师除了培养学生的数学思维之外,应格外注重学生曲数学文本知识的体会与理解。本文从培养学生的读题习惯,提升审题能力、学会品读绘图、练习插图品读、细品实践插图等方面对小学数学教学中如何培养学生的“品读”能力进行了初步地探索和研究。

语文教学中的“品读”艺术

“读”是语文教学中最常用的教学方法之一。苏联著名教育家苏霍姆林斯基曾说过：“我曾试用许多手段减轻学生的脑力劳动，结果得出一条结论——最有意义的手段就是扩大他们的阅读范围。”由此可见“读”的重要意义。语文教学应如何充分发挥“读”的作用？笔者认为在教学中教师要勇于突破常态，敢于创新，引导学生善于品读课文的内在美。

小学语文教学中运用品读的策略与实践

由于当前教育水平不断提高,现代科技与社会氛围等因素影响增加,传统的教育模式和方法已经不能适应现代教育的需要,因此教师就更要发挥好引导者的作用,以创新性思维与方法去引导学生学会自己品读课文内容,实现以“品读”为核心的语文学习。教师可以带领学生展开交流活动,分享彼此的心得与独特的体会、想法,提高学生的理解能力与品读能力,让学生在收获语文知识的同时获得快乐,实现精神上的满足,在品读中提高自己。本文将结合教学实践,分析六年级语文教学中“品读”的作用。

Reading, Text, and the Metaphors of Perception

Literature continues to generate controversies as to what it is and what it is for. That is one of the reasons for the proliferation of ＂literary theories.＂ The notion is here placed between quotation marks because it does not mean the same thing to all the scholars in the field. Some regard it in the same way that theory functions in the sciences, where it focuses on the object it is associated with. For example, the atomic theory of matter is concerned with the internal constitution or the characterizing properties of matter. Others, however, are looking beyond the object towards the reader and the extra-textual environment. The approaches to literary studies which look beyond the individual work to outside phenomena are many and increasing all the time as new issues and concerns arrive on the social scene. Issues of climate change are fairly topical now; and criticism is already responding with such ideas as eco-criticism. The question of the identity of the literary object has to be kept in the front burner, so that it is not swamped by the many different interests which attach to literature from time to time. Bringing attention back to the literary work is the central concern of this paper; and we are doing this by way of the metaphors of perception often used with respect to the literary work as these suggest that the work is something to focus on, rather than to see through to something else. Finally, I elaborate the concept of integrity as an appurtenance of the literary text that attracts and holds the gaze.

An interpretation of alienation theme in J. D. Salinger＇s The catcher in the rye and Nine stories

J. D. Salinger is an alienated writer, who alienates himself from the dominant society. He is unsocial in character and unconventional in behavior. His reclusion can be regarded as the behavioral presentation of his alienation. Salinger also portrays many alienated characters in his The catcher in the rye and Nine stories. These alienated characters include children, adolescents and adults. They alienate themselves from dominant social culture, groups and even themselves. According to the analysis of these alienated protagonists from autobiographical and historical perspectives, the root of their alienation lies in the conflict between their searching for the ideal love and the absence of such love in the dominant society. So comparing with enjoying substantial life, Salinger＇s works can arouse people＇s interest and give more concern to their spiritual life.

Musical quality in Edgar Allan Poe＇s poetry

Edgar Allan Poe is one of the greatest writers in American literary history. He was a short-story writer, fathering the detective story and starting the psychoanalytical tradition. He was also a poet, advocating short poems with regular and delicate rhyming schemes. He was, at the same time, a literary theorist, writing about the principles of composition. This paper is to analyze the theme and musical quality of Poe＇s poems, focusing on the techniques Poe had employed in his poems to help enhance his major themes of death and beauty. According to Poe, the most appropriate tone for all poems is melancholy. In Poe＇s life, there was a personal connection with ＂the death of a beautiful woman＂, which is acknowledged in his thesis The philosophy of composition. The impetus for composing of poems undoubtedly arose from Poe＇s loss of his mother and of other women he had loved. The beauty of music exerts great influence on Poe＇s aesthetic perception. He paid more than enough attention to the musical qualities of poetry. He defined poetry as ＂the rhythmical creation of beauty＂. Poe advocated the idea of the poet as a craftsman, interested in polishing and refining language. He stressed the use of language as a medium of convey pure musical and rhythmical beauty. Poe＇s reputation for musical verses is due to his choice of sounds and treatment of rimes and meter.

Eveline＇s awakening of woman consciousness—— The analysis of Eveline by James Joyce from the perspective of feminism

Eveline is one of the stories in Dubliners by James Joyce, a story about moral paralysis and a quest for vitality in vain. This paper attempts to analyze the protagonist of the story, Eveline＇s awakening of woman consciousness and make a tentative probe into the factors that lead to her final subservience to the patriarchal society.

To sex in Ragtime

＂More than a book, it＇s an experience--startling, viscerally satisfying, and as joyous as a happy love affair--Cosmopolitan＂ （Doctorow, 19751）. E.L. Doctorow＇s masterpiece Ragtime has intrigued quite a great deal of critics＇ attention worldwide. However, ironically, hardly any attention was paid to the sex and lovemaking scenes in Ragtime which have been overshadowed by Doctorow＇s splendid and original post-modernist approaches. The author wants to take up this challenge and commit herself to the appearance and role of sex and lovemaking scenes in Ragtime and more importantly, the deeper meanings behind them. Hopefully, this paper will give new perspectives to the understanding of this novel.

The Emotional Interpretation of the Products Design in the Emotional Economy Era

This paper, based on the basis of the discussion about emotional design, tries to put forward the method of emotional deduction, to provide reference for the product design strength.

Analysis on chivalry and its influence

Knights appeared and flourished in the Middle Ages. Some scholars call the Middle Ages the ages of knights. Knights were cavalrymen in heavy armors and played a decisive role in the battlefield in the Middle Ages. They were also an important social class and strictly abided by the code of chivalry, which had a far reaching impact on the social culture and attitudes towards women of the Western Europe even after the decline of the knighthood.

The Processualities of Literature

The objective of this paper is to demonstrate that the processual aspect of literary works of art deserves much more attention than it normally receives by readers, critics, and theorists. The most important reason for this is seen in the fact that texts since the advent of print culture have been disseminated and passed on in written form and that in the medium of writing the processual character of language is only insufficiently taken care of by a cultural convention of arranging and approaching the presented signs in an particular sequence. Whereas in an oral culture the dynamic processuality of a speech or recitation was directly experienced by the listeners, the spatial arrangement of signs in writing enables and even entices readers and critics to read this or that part of a written text in a sequence of their own making. What remains out of focus is that in doing so they miss the particular semantic profile and aesthetic character of the work as created by the author--a procedure particularly hurtful in the case of literary works of art. There is hope, however, that this will somewhat change by our moving towards a performance culture

The Guidance and Meaning directed by the Three Phases of Memory on the Reading of Literature Works Written by the Style of Stream of Consciousness ——taking the Work Hear the Wind Sing by Haruki Murakami as an Example

Recently, the researchers put their attention on the literature works on Virginia Woolf or James Joyce too heavily just because the skill of stream of consciousness is used through the novel completely. Choosing this novel by Japanese writer as an example is an experiment, because the stream of consciousness as a composing method has melted its impression into the modem novel. And in the researcher＇s opinion, regardless the traditional part, the researching focus should be shifted on the works written by nowadays writer. To begin this paper, there are four questions should be solved： First, the definition of stream of consciousness should be known clearly; another question is the structure analysis of structure of Hear the Wind Sing; secondly, compared with the mental space theory and blending theory by Fauconnier, how to judge the function of Three Phases of memory＇s direction on reading should be focused on; thirdly, the reason why readers meet the problem of barrier when they read the stream of consciousness novel, and how the memory helps to solve the problem should be study in this section. Fourth, the extra factors which support the function of memory will enhance the skill of reading the SOC novel and finally foreground the meaning.

Borges＇ Poetics of Visible Unrealities

Close reading and inter-textual analysis of Borges＇ essays, fiction, and poetry suggest a poetics of visible unrealities, a fiction that calls attention to its own artifice. Borges＇s poetics of reading and dreaming require another poetics of the work as a text that calls attention to its own artifice. In reading Borges＇ fiction, the separate roles and identities of reader, writer, and work of fiction merge and exchange roles, powers, and identities and are transformed into a single act of dreaming, which assumes cosmogonic and apocalyptic risks. In the dominant role given to the reader, the work of fiction as an object or work of art does not exist unless it is read. There is no determinate text, only a version of our own we re-write and invent every time we read the text. The author＇s reading is not a spontaneous evocation of vision, but an artifice, as artificial as the writing of the fiction. As writers and readers we are composed of texts and schemata, alphabets and artifacts, not merely mental perceptions and ideas. The reader requires a prior text to copy, translate, and recreate, and that text only exists as a fictional microcosm in so far as it is being read by a Reader who is able to actualize the revelation only imminent within it.

The Metaphor of Narrative Woods in Eco＇s Work

This paper on Umberto Eco＇s contribution to the narration process, tries to identify the mainstream of modem studies of the text. I have tried to separate it as an entity, which together with other textual techniques and strategies shall create applicable theoretical messages towards an artistic creation. Eco＇s （1994） work itself, gives an opportunity to exemplify his theoretical claims. Using my examples, I have tried to show how a work of art can be rendered narrative, a subject to contemporary techniques and cooperativeness with the reader. One of the main issues I have explained is the time factor, seen from the linguistic and semiotic prospective. I consider that Eco＇s treatment of the relation between reality and fiction is of a semiotic nature. One of the main elements it contains （and definitely makes such a difference possible）, is the time factor. The delay （lingering） part treats works of art separately, and gives one of the ways to render artistic works readable, worth having an aesthetic value, in their way to transmitting a message to the audience.

Spectrophotometric Error Due to Uncertainty in Reading the Signal

Based upon the standard deviations for the intercept and the slope of a linear regression line, as well as by differentiating both Beer＇s law and a linear relationship between transmittance and concentration at high transmission, it is proved that the relative spectrophotometric error of a measurement becomes greater as the sample concentration only decreases. Further, it is demonstrated that the present knowledge with regard to the error in absorption spectrophotometry is necessary to be reexamined. The total scale of transmittance can literally be used for measurements, unfolding workable dynamic ranges about two orders of magnitude lower than usually and thus absorption spectrophotometry can efficiently compete with other methods of analysis with respect to detection limits.
