对学生学习方式的几点思考

针对学生学习方式单一化，被动学习的现实，我们应该树立以学生发展为本的民主化教育思想，深刻认识造成学生被动学习的原因，改革课堂教学，激发学生学习的主动性，自主性，能动性和创造性，为学生实践多种学习方式创造条件，使接受学习和自主发现学习相得益彰，实现学习方式的多样化。     

"自主性学习"在物理课堂教学中的探索

“自主性学习”是当代教学的基本思想,教师要努力创设机会,激发学生学习兴趣,使学生成为学习的主体,让学生的学习由被动变为主动。文章结合物理课堂教学做了深入探索。     

浅谈网络环境下的高中信息技术教学设计

信息技术在课堂教学中的应用更加深入和广泛，已经引起学习方式和教学方式的深刻变革，它要求教学设计要相应变化.由教师教转变为学生学，由学生的被动学习转变为主动学习，由学生的接受式学习转变为探究式学习.

固体物理教学中的功能训练陕西师范大学雷洁在固体物理教学中，我们针对学生的具体情况，强化了功能训练，提高了学生的学习兴趣，增强了学习效果，为进一步深化教学改革积累了经验。所谓功能训练，就是在进行正常的课堂教学的同时，加强学生的学习活动，使学生由被动接受...     

善待学生，营造“民主、自由、和谐”的学习氛围

经过几年的教学实践，新课程的教学理念已深入人心，课堂教学形式开始出现转变，学生的学习方式与教师的教学行为也发生了根本性的变化，使学习方式与教学行为由传统的偏重教师教授转变为立足学生的发展，注重学生的主体性学习，把学习的主动权还给学生，使学生在教师引导下，由被动的“要我学”转变为主动的“我要学”，从而培养学生的创新意识和创新能力。[第一段]     

把创新带进课堂

新课程的核心理念是“一切为了每一位学生的发展”，从这个理念出发，教育要以人为本，着眼于人的培养与发展，使学生养成终身学习的愿望和能力。这就要求我们在课堂教学中一方面要求学生改变学习方式，由被动接受、记忆、模仿的过程变为主动探究、自主发现、合作交流的过程。另一方面，要求教师成为学生学习的参与者、促进者、指导者。那么，在新课程中，教师怎样把创新的意识带进课堂教学呢？     

探究性学习在历史课教学中的应用

走进中小学课堂我们不难发现，课堂教学模式基本上是灌输-接受，学生学习方式基本上是听讲-练习-再现教师传授的知识，学生完全处于一种被动的状态。这种教学模式使学生学习方法机械、呆板、靠死记硬背完成学业。     

英语课上如何落实学生的主体地位

学生是学习的主人，是发展的主体。落实学生在课堂教学中的主体地位，是指教师在课堂教学中设法为掌握着学习主动权的学生创造必要的智力发展条件、提供必要的指导与帮助，使学生主动发展，从而由被动接受知识的客体变成学习过程中的积极能动的主体。《英语教学大纲》明确指出：“要始终体现学生的主体地位”。英语教学的实践也已经证明：切实落实学生的主体地位，真正让学生动起来，对于激发学生的学习动机，挖掘学习潜能，培养学生的创新精神和自学能力，都具有重要意义；也只有落实学生的主体地位，才可能最大限度地发挥学生在学习上的能动性，在主体有目的的活动中，完善和发展自身的素质。那么，英语教师如何优化课堂教学，落实学生的主体地位呢？

促进日语会话教学改革全面提升学生会话素质——高职日语会话教学之管见

在就业竞争日益激烈的今天，作为高职院校的教师，为实现学生日语素质与日资企业需求的无缝对接，在日语会话教学中，打破传统课堂教学模式，全面采用“教学圈”模式。更应强调“研究性学习”、“任务型教学”，通过优化组合多种媒体，精心创设会话情景，来全面调动学生的会话兴趣。以学生的发展为根本，凸显学生的自学，以获得亲身参与研究探索的体验、培养发现问题和解决问题的能力、学会分享与合作，使学生由书本的学习变成走向生活的学习；从非兴趣的被动学习走向由兴趣而发的主动学习；由单纯依赖老师的学习转为以学生为中心的自我学习。     

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.

橡胶颗粒沥青混合料低温抗裂性试验研究

以AC-13级配为基础,将橡胶颗粒代替部分集料掺入混合料中,以低温弯曲试验为评价方法对不同橡胶颗粒掺量下沥青混合料的低温抗裂性进行研究,并引入应变能密度值对混合料的低温抗裂性进行综合评价.试验结果表明:橡胶颗粒沥青混合料试件的破坏微应变均超过2 300,满足冬寒区的技术指标;无论是否掺加橡胶颗粒,随着温度的下降,沥青混合料破坏时的最大弯拉强度增大,弯拉应变降低,劲度模量增大;弯曲应变能密度在胶粒掺量为1%左右时具有较大的弯曲应变能密度值,此时橡胶颗粒沥青混合料具有较好的低温抗裂性.     

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-
