试论中学英语课堂的师生互动

师生互动对于语言课堂的作用得到二语课堂研究者的广泛关注。我国中学英语课堂的师生互动存在互动模式单一、互动对象差异大、非言语互动未得到重视等弊病。教师必须理解师生互动的本质和内涵,不断反思互动的在教学中开展的实际效果,通过设置合理教学情境、提倡师生平等、提高教学评价质量等手段,使英语课堂的师生互动更有成效。     

课堂互动理论在大学英语口语教学中的应用(英文)

外语课堂互动中的支架作用

英语课堂教学研究着眼于课堂互动与语言输入、输出,旨在了解课堂互动是否有利于学生掌握语言,以便改进课堂教学效果。实践证明:在“输入“和“输出“之间起桥梁作用的是课堂互动。通过师生互动、学生互动等形式,使课堂成为交际的场所,可有效提高教学质量。但有效、成功的互动必须借助支架,恰当的支架可以使互动更具有可操作性,可以为互动创造和谐的环境。     

新世纪英语教学课堂互动新论

随着教育体制改革的深化,越来越多的教师已经接受课堂互动这一教育理念,开始重视课堂互动。本文阐述了课堂互动的重要性,总结了课堂互动的类型。尽管教师已经意识到课堂互动的重要性,努力创造一个互动性更强的师生交流关系,但在具体实践中还有很大偏差,课堂互动应该是多维的。本文还总结了课堂互动实现的重要因素:反馈和沟通,发挥学生的主体作用,合作学习。互动包括意见协商与反馈,这些是第二语言成功发展的决定性因素。在课堂互动中,学生应该是课堂活动的中心。合作学习推动课堂互动达到了前所未有的地位。     

浅谈数学课堂理答

一、问题的提出 在新课程理念的倡导下，我们的数学课堂发生了许多可喜的变化。传统课堂上以教师讲授为主的“满堂灌”的教学方式得到了较大改善，教师们越来越重视学生的思维开启、学生的自主探究、学生的积极参与和互动，数学课堂变得活跃，教学效率也得到提高。     

学生参与活动设计以构建大学英语口语互动课堂

Krashen的可理解性输入假说、Long的协商互动理论以及人本主义教学理论都要求人们更加重视外语课堂上,尤其是口语课堂上的师生互动、生生互动。课堂互动的本质在于课堂活动,在国内教育界,采用什么样的课堂活动大多是由教师决定的。经过一定的调查研究以及对比前人的研究发现,师生对课堂活动的看法在很大程度上存在差异,这种差异不可避免地影响了口语课堂的互动效果。在分析原因的基础上,除了教师的努力外,发挥学生的主动性,鼓励学生参与活动设计也对构建大学英语口语互动课堂产生了显著的积极意义。     

大数据在高校文科生课堂panel教学模式中的应用

当前,大数据理念和技术已经在社会各个行业和业务活动中得到广泛应用。高校文科生课堂panel教学模式是一种创新型的课堂互动模式,在其多个环节,如话题设定、主持人引导、台上学生讨论和台下学生提问与互动等,都需要大数据思维和方法的支撑。在大数据支持下,教师的课堂引导力、学生的课堂参与力以及课堂的教学效果较之传统教学方式均会得到显著改观。具体来说,大数据在高校文科生课堂panel的应用体现在数据采集、治理模式、教育教学、资源调控、考核评估5个方面,因此,对应地需要成立高校文科生课堂panel大数据库、加强核心数据和相关数据的采集与完善、加大课堂相关数据处理力度、提高数据内容的挖掘与分析能力、重视改善教学效果的数据信息应用,推动大数据在高校文科生课堂panel教学模式中的应用。     

努力实现有效互动优化语文课堂教学

新课程呼唤充满生命力和创造力的课堂，教师应创设民主、宽松的课堂气氛，激发学生情感参与；有效地组织、引导学生积极地投入参与合作探究；着力采用多元参与的互动评价，使学生在愉快的课堂氛围中得到全面发展，以调动每一位学生的学习积极性；并采用现代媒体辅助教学，优化教学手段，让学生在互动中发展。

平板电脑环境下的课堂互动行为分析

为了更加准确地表征基于平板电脑的课堂互动形式,在对课堂互动分析工具OOTIAS深入研究的基础上,结合通过课堂观察法收集到的平板电脑具体互动方式为依据,提出基于平板电脑的课堂互动分析系统(Tablet-PC based Interaction Analysis System,简写TPCIAS),并使用该编码系统对S市一所小学的数学课堂教学进行分析。结果显示,平板电脑环境下的数学课堂教学对学生提高学习兴趣、增强课堂参与度效果显著;对教师创新课堂互动的形式、增添课堂活力带来帮助。最后提出平板电脑在小学数学课堂教学中的使用建议。     

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
