小学低年级写话教学的四要素

写话练习是小学低年级语文教学中必不可少的环节,新课标低年级写话的建议是使学生对写话有兴趣,写自己想说的话,写想象中的事物,写出自己对周围的认识和感想。孩子的童年是五颜六色的,诗意的色彩也是不容忽略的。因此,低年级写话需要兴趣、真实、想象和诗意四要素的结合。     

结合部编教材谈低年级写话教学

低年级写话是作文教学的启蒙,是小学生写作习惯和兴趣的养成阶段。课标对低年级写话也做出了要求:"对写话有兴趣,写自己想说的话。(写想象中的事物,写出自己对周围事物的认识和感想)"。作为教师,要引导学生学会从教材中汲取方法,在生活中获得素材,在阅读中丰富积累,感受写话的乐趣,从而爱上写话。下面就跟着笔者结合部编版教材一起去探索一下低年级的写话教学。     

关于小学低年级作文教学的几点看法

看图作文和写话教学是小学低年级作文练习的两种重要形式,看图作文包括看图和作文两个方面。看图是作文的前提,是关键,也是它同一般作文的根本区别,因此,要写好看图作文,主要是解决看图的问题。而语文课程标准》对小学低年级写话教学提出了如下的要求:"1、对写话有兴趣,写自己想说的话,写想象中的事物,写出自己对周围事物的认识和感想。2、在写话中乐于运用阅读和生活中学到的词语。3、根据表达的需要,学习使用逗号、句号、问号、感叹号。要做好小学低年级作文教学,看图作文和写话教学是两个重点内容。     

论培养小学低年级小学生的写话能力

小学低年级学生是从写话开始来锻炼作文能力的,以自己的教学体会,培养低年级小学生的写话能力,需要教师以输送、启发、模仿的作法来培养他们的观察能力、想象能力落笔能力,让他们感受到写话不吃力,写话很有趣,在他们写出的话中有情有义。     

浅谈低年级写话的规范训练

《语文课程标准》对小学低段写话教学提出了明确的要求:1、对写话有兴趣,写自己想说的话,写想象中的事物,写出自己对周围事物的认识和感想。2、在写话中乐于运用阅读和生活中学到的词语。3、根据表达的需要,学习使用逗号、句号、问号、感叹号。这段话为低年级的"写话"规范教学指明了方向:培养学生兴趣,乐于表达;灵活运用词语,善于表达;合理使用标点,规范表达。     

指导低年级学生写话的几点体会

写话教学是中小学作文教学的重要基础,低年级学生正处于启蒙阶段。新课标十分注重低年段学生的写话教学,它要求我们的学生"对写话有兴趣,写自己想说的话,写想象中的事物,写出自己对周围事物的认识和感想。"这需要老师不断的指导和帮助,让孩子们睁开眼睛,注视一切事物,竖起耳朵,倾听万物的声音,培养他们对生活的热爱,提高他们理解生活的能力,促进写作能力的提高。     

凡学文,初要胆大——习作教学变革尝试

学生是学习的主人,写作是学生的一种自由表达,是精神领域的一种自我需求,更是一种追求自我成长的表现。无论是低年级的写话,还是中高年级的习作,都应该是学生自己的"自写作"、"自由表达和有创意的表达",也就是"写自己想说的话,写想象的事物"。     

浅议低年级写话能力探究

作文教学是一个系统的教育工程,有着其一定的积累内化。作为教过中高年级、现在执教低年级的我,认为在低年级重视写话训练,对于中高年级的习作水平的提高有着不可估量的作用。那么,怎样训练低年级学生写话呢?本人从重视读、听、说训练;激发想象;跨学科训练,达到综合性学习三方面来训练、提高学生的习作水平。     

新课程标准下如何培养学生的写话能力

<语文课程标准>提出了低段的写话教学要求:"对写话有兴趣,写自己想说的话,写想象中的事物,写出自己对周围事物的认识和感想.在写话中乐于运用阅读和生活中学到的词语.     

利用绘本促进小学生写话能力教学策略研究

写话是习作的启蒙阶段,然而在实践中不难发现,因为低年级儿童识字量少,阅读积累相对贫乏,不少孩子缺乏良好的语感,时常会陷入无话可写或词不达意的尴尬境地。本文从教学内容的角度,实践绘本助学的阅读方式,通过仿写、采写、补白、续写等阅读策略,发挥绘本的核心价值,引导低年级儿童"悦读"、"悦绘"、"悦写",培养良好语感和想象能力,拓展写话思维,提升语文素养。     

Students' Reactions to the Introduction of Videoconferencing for Classroom Instruction

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors.     

Cooler temperatures inductive to locust outbreaks

Ajoint study by Prof. ZHANG Zhibin from the CAS Institute of Zoology and his co-workers from Norway, US and Swiss have indicated that historical outbreaks of migratory locusts in China were associated with cold spells, suggesting that China＇s projected climate warming could decrease the pest＇s numbers. The study was published in Proceedings of theNational Academy of Sciences on 17 September, 2007.     

Exploring Multiplexity: Social Network Structures in a Computer-Supported Distance Learning Class

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction.     

The Role of Intermediating Institutions in the Diffusion of Electronic Data Interchange (EDI): How Industry Associations Intervened in Denmark, Finland, and Hong Kong

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies.     

How Electronic Publishers are Protecting Against Piracy: Doubts About Technical Systems of Protection

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means.     

Rough Justice: A Statistical Assessment of ICANN's Uniform Dispute Resolution Policy

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP.

Monoculture Rubber Plantations Have Negative Ef ects on Controlling Splash Erosion

<正>In Xishuangbanna,one of China’s most biodiverse regions,landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations.In steep areas,terraces are often constructed before planting rubber trees,which causes two important changes in the soil:the destabilization of soil in the bench terraces and the increased vulnerability of unvegetated riser faces to erosion.Few studies have documented the nature and intensity of erosion on bench terraces.Prof.LIU Wenjie and his colleagues from the Xishuangbanna Tropical Botanical Garden(XTBG)conducted a study in Menglun County(21°5′39″N,101°15′55″E),Xishuangbanna to evaluate the influence
