浅谈新课改下数学教学的探索

在新课程理念下，高效的数学课堂教学要以学生的进步和全面发展为宗旨，教师必须具有全方位数学教学理念，转变观念，更新教法，钻研教材，尝试科学的教学法，使学生在有效的时间内，掌握尽可能多的数学知识，促进学生的全面发展、自主发展和个性发展。     

新教材中直线与圆方程的教学分析

新课程强调全面提高学生素质、促进每一个学生的发展,展示知识的产生、形成、创新和发展过程,培养学生的创新精神和实践能力,允许学生对问题有独特的见解等新的理念。新教材就是围绕这些理念进行改编的,新课本在继承旧课本优点的基础上有所创新,教师要充分利用教材中的素材,促进学生的学习兴趣。这就要求教师在教学实践中要为学生发展留出充分的活动空间,改变教学方法和备课方式,创造性地运用教材。文章以直线和圆方程为例作教学分析。     

例谈创造性使用教材

教材是最主要的课程资源，数学教材是学生数学活动的基本凭借。但实际教学面对的是不同的学生，教材未必能切合具体学生的实际需要。这就要求老师教学中既应以教材为主要依据，又要根据本班学生的特点和实际情况，灵活地、创造性地使用教材。只有坚持立足于教材，又不囿于教材，注意根据教学需要合理使用教材，才能促进学生主动学习，主动发展。     

谈新课程背景下的数学教学策略

落实新一轮国家基础教育课程改革的培养目标，教学是关键。随着数学新课程的理念、功能、内容和结构的变化，必将对数学教学策略提出更新、更高的要求。数学教师应通过制定合理的教学目标、创设良好的教学环境、合理开发利用教材、实施有效的课堂教学、培养学生自主学习能力等方面展开教学，提高学生数学素养，促进学生全面发展。

“语文教学与学生自我发展”课题实验与思考

"语文教学与学生自我发展"课题实验,基于革除传统语文教学的弊端并着眼于语文教育的发展,以学生的自我发展为中心,更新语文教育理念,整合教材,开发和利用各种语文课程资源,建构符合新课程的语文课程体系,深入研究语文教学促进学生自我发展的方法,课题实验取得了显著成效,获得了多方面的启发.     

科研与教学结合促进人才培养

高水平的科研成果是支撑和提高教师教学水平的重要基础。科研成果进教学实验和课程实践,可以让学生直接获得最新的理论和实际锻炼机会,合作教育成果进入教材可以丰富教学内容,科研成果进课堂可以让学生强化工程理念和工程研究方法。科研与教学的结合,有利于促进教学发展,提升教学品质,进而提高学生的工程能力和专业素质。     

实施开放式教学促进学生发展

本文结合教学实践，就如何在《品德与社会》教学中实施开放式教学，促进学生发展，从灵活使用教材等四个方面展开了论述。     

美术新“课标”实践与教师教育观的转变——关于《初中美术教学大纲》和《美术课程标准》中的课程实施建议的对比分析

本文通过对《初中美术教学大纲》和《美术课程标准》的对比分析，通过对二者的教育理念、教学目标和教学内容等的对比分析，寻找二者的异同。结合自己在运用现有的美术教材进行的美术教学实践，对新课标理论的一些探索和运用，从课程建设的角度阐述了美术课程新标准的作用：促进了美术教育观的转变，促进了美术教材模式、学生学习方式和课程评价方式的变革，有效地运用各种资源，增强了美术教学效果，充分发挥了美术教育在素质教育中的作用。     

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.     

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
