建构主义学习理论与语言教学系统效能的关系

建构主义学习理论强调学习的建构性，学习的社会性和情景性。建构主义认为：学习中学习者是主体，认知是一个主动建构过程，而且主体的认知结构处于不断发展之中。基于建构主义学习理论的语言教学系统与传统语言教学模式存在着显著不同，促进了多媒体语言教学模式的发展，促进并形成了教师、学生、媒体和教学内容等各要素间能动交互的稳定的结构形式，为实施建构主义理论教学提供了技术支持，并取得显著效果.     

建构性语言学习的实施策略

根据建构主义学习理论，从学生本体角度探讨有效的语言学习方法，提出了问题讨论法、情景角色法、小课题研究法等重构意义的学习方法，并注重改善语言学习环境，激发学生学习的主动性和积极性。     

建构主义学习理论在Java语言教学中的应用

建构主义强调以学习为中心,学习者是学习的主体。建构主义不仅形成了全新的学习理论,也正在形成全新的教学理论。建构主义的四要素包括情境、协作、会话和意义建构。Java语言是一门面向对象程序设计语言。通过介绍建构主义学习理论在Java语言教学中的应用,说明了在教学情境的创设方面的具体方法和技巧。     

因特网与第二语言学习中的建构主义

因特网应用于第二语言学习时存在一些问题和不足,但它为以英语作为第二外语的学习者提供了充分接触目标文化及语言本身的最好方法.建构主义学习理论与第二语言习得的联系其实是与通过因特网学习语言的机会相联系的.     

支架式教学模式及其在大学英语教学中的应用

源于建构主义学习观和维果斯基最近发展区理论的支架式教学模式，近年来受到语言教学界的广泛关注．文中简要介绍了支架式教学模式的理论基础，讨论了它的五个环节，并结合教学实践，探讨了如何在大学英语教学中运用支架式教学模式。     

数字语言实验室对外语教学的效益分析

本文介绍了数字语言实验室的概念、发展过程、组成，并从课堂教学、网络化自主学习、考试功能、实验室管理等方面总结分析了数字语言实验室对外语教学的正面影响。其结论是：数字语言实验室是当前外语教学最先进、最有潜力、最具发展前景的现代化教育手段之一，利用它进行外语教学教学是当今教育发展的必然趋势，各级学校应积极并广泛使用。     

对外汉语词汇教学中的语境设计

语境教学方法的提出基于的是建构主义教学的发展。语言的习得规律是以＂建构主义＂为理论支撑的,它强调学习的情景性,认为语言学习不是被动接受的过程,而是主动建构的过程。教师不仅仅是知识的传授者和灌输者,更应是组织、指导、帮助、促进学习者利用情景、协作、会话等环境要素发挥学习积极性、主动性的引导者。这一观点的提出为对外汉语词汇教学的方法提供了新的,有效的途径。本文正是以建构主义的理论为指导,论述了语境在对外汉语词汇教学中的的重要性及其运用的方法和原则。     

自主语言习得理论及其应用

自主语言学习是近二十年来语言学习领域频繁出现的术语。它以建构主义和人本主义心理学为理论依据,提倡发挥个人的主观能动性,体现了"以学习者为中心"的教学思想。自主学习的条件是学习者须具有一定的认知和元认知策略,对学习抱有积极的态度和动机,并有一定程度的自尊,同时也不能忽视教师的指导和推动作用。本文还提供了实现自主学习的几种方法。     

埃尔金建构主义的逻辑根基

埃尔金以“不当步骤”和“正确物”思想改造传统建构主义，并通过解释名称指称为之作出系统辩护。她强调诠释和理解在解释语言-世界之间关系中的作用，以此批判主流名称指称理论，并对指称概念进行扩充。埃尔金为其建构主义的辩护是不彻底的，但它道出了融合分析哲学和诠释学重构认识论的必要性。     

非英语专业研究生专业英语学习中的思维瓶颈——建构主义理论视角下的教学设计

针对非英语专业研究生专业英语学习中的思维瓶颈及其产生原因，结合建构主义知识观、学习观以及教学观对思维能力的培养，本文从建构主义几种典型的教学模式入手提出了解决专业英语学习思维障碍的教学设计，旨在建立以语言促思维并以思维促进语言学习的良性互动循环。     

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.     

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     

An affordable accurate evaluation of the binding conformations predicted by molecular docking studies in bio-system

Franck-Condon factors bridge the gap between theoretical modeling and experimental observations for molecular electronic spectroscopy and electron transfer.Under the displaced harmonic oscillator approximation,multidimensional Franck-Condon factors are decomposed into a product of many one-dimensional(1D)Franck-Condon(FC)factors,and each 1D-FC factor is associated with one Huang-Rhys factor that determines the leading contribution of
