中小学教师与教育教学研究

本文结合基础教育新课程改革分析和研究了当前中小学教师从事教育教学研究的意义、有利条件、不利条件、当前存在的问题及改进的措施等.     

试论新课改背景下的师范教育改革

在知识经济和信息时代的背景下,我国适时地在中小学实行了基础教育阶段的新课程改革,因而也对教师提出了更高的、新的要求。作为"教师摇篮"的师范教育应积极应对这种改革,对此做出反应,在教育目标、教学过程、教学内容、学生评价、教育科研以及与中小学联系等方面积极改进,以培养具有现代教师素质,能适应并推动新课改的新型教师。     

中小学教师从事教学研究的意义及途径

在新课程改革的背景下,中小学教师从事教学研究具有更新教育理念、解决新教材使用中的实际问题、提升教师的专业化水平等现实价值.中小学教师可从阅读别人的理论成果、参加教研活动、课堂教学、教学手段等方面进行教学研究.     

课程改革的理性反思

在全国基础教育课程改革由点上开花到面上突破的实质推广阶段，作为国家级首批课程改革实验区，深圳市南山区对四年来新课程实施的情况进行了全面调研，形成了调研总报告和八个分报告。该区部分中小学领导对新课程实践进行了回顾与反思，直面新一轮基础教育课程改革的实践困惑，比较深入、系统地探讨了新课程创新的精神实质、观念与行为存在距离的原因、综合课程存在的问题、新课程实践中教师教育科研的对策以及新课程评价改革的出路等问题。     

教育科研:促进中小学教师自主发展的有效途径

自主发展是基础教育新课程改革目标对教师提出的客观要求.教师教育要着力培养教师自主发展的意识与能力,通过把教育科研融入到教师的教育生活之中,使教育科研成为教师的一种生活方式,从而生成一种终生学习,终生教研的能力.使其在教育教学过程中,能主动参与基础教育新课程改革,主动发展自己的专业能力,教育科研是促进中小学教师自主发展的有效途径.     

从我院改革实践看教育学院的必由之路

<正> 勿庸置疑,教育学院对于弥补十年动乱给教育事业的带来损失,对于提高中小学教师学历结构,对于提高全体中小学教师的素质,对于培养德智体美劳全面发展的社会主义建设者和接班人,一句话,对于提高整个中华民族的思想文化素质,已经作出了不可磨灭的贡献。十多年来,教育学院有过她的黄金季节——学历进修的高潮。然而发展到今天,在市场经济和改革开放的新形势下,她又面临着严竣的困难和挑战。在学历进修工作基本完成     

教师合作发展模式构建的瓶颈与对策——基于教师专业发展学校本土化的思考

"教师专业发展学校"本土化模式,业已成为我国教师教育改革发展实践的主要方向。然而,由于大学、中小学教师场域文化的冲突、大学教师教育自身发展问题、合作机制不健全等现实因素的影响,使大学与中小学合作伙伴关系的建立困难重重。由此,建立平等对话的合作机制、强化教师教育的实践性,重视师范生的指导、完善大学内部跨专业合作机制、改革教师评价和激励机制、建立合作组织管理规范、完善合作契约机制,才能实现大学与中小学的有效融合。     

关于高师院校公共教育学课程改革的探索

随着我国基础教育新课程改革的不断推进,教育学作为高师院校教师教育专业学生必修课程,在教育学课程功能的认识、教学内容、教学手段、教学方法和考核方法等方面存在的问题和弊端也日渐凸显。如何重新认识教育学课的价值,探讨新的教学模式,培养高素质的教师,使教育学课的教学与新课程改革接轨,已成为高师院校公共教育学课改革的关键。     

教育科研:需要中小学教师具备哪些素质

基础教育新课程改革要求中小学教师成为教育教学的研究者,这也就对中小学开展教育科研提出了直接的要求。但当前中小学教育科研的有效性很低,其中很重要的一个原因是不少中小学教师缺乏从事教育科研的内在素质和条件。在本文,我们就中小学教师从事教育科研的内在素质这一问题进行分析和探讨。     

新课程标准下的中小学体育教学创新探析

随着我国基础教育体育课程改革的不断向前推进,广大教师在努力实施课程改革。通过文献资料的查阅,不断地摸索体育教学新的观念、内容、方法、组织;师生互动;对学生的评价以及教学环境的创建几个方面,提出了中小学体育教学中贯彻和落实新课程指导思想的途径,旨在为中小学体育教师能够尽快地理解新课程,推动学校体育教学的改革和发展提供参考。     

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the
