《金属材料与热处理》课程的生动教学案例

《金属材料与热处理》是技校教育中比较重要的一门专业基础课,该课程的特点是概念多而繁杂,理论抽象,难度较大,课程比较器立导致进而导致该课程学生学习起来比较枯燥乏味,学生缺乏学习兴趣。所以需要在教学中通过多样化,多层次、多途径的教学课程设计,制追教学亮点,实施兴趣教学,从而收到良好的教学效果是教师不断追求的目标。     

基于激发职教生学习兴趣之探究

职教生是一特殊群体,他们的共性是一般学习兴趣不高,学习比较被动,自主学习能力比较差,课堂依赖教师多,主动交流少,这使理论教学不仅从整个课程开设上没有真正落实教学目标,而且过早的压抑了学生学习的兴趣,甚至会使学生产生厌学情绪。作为职教教师我一直在考虑怎样激发他们的学习兴趣,特别是计算机课程的教学。     

《微机原理与接口技术》教学现状与改进

《微机原理与接口技术》是一门内容比较抽象，初学者较难理解的课程。随着计算机科学的快速发展和教学改革的不断深入，教师在微机原理与接口技术课程的教学中遇到课程内容落后、实践教学薄弱和学生学习兴趣不高等问题。针对这些问题，提出融入先进概念、优化课程内容、更新实验设备、强调实践教学、丰富教学方法等措施，以激发学生学习兴趣。

提高韩国语精读课程教学趣味性之我见

任何一门外语的教学,精读课程无疑是专业课程中的首位。但是,因为精读课程的定位及它的教学内容,教学的过程难免枯燥乏味。如果教师只是按照教材的内容施教,学生就会在单一重复的教学模式中无法感受到学习的乐趣,进而失去学习的兴趣。兴趣是最好的老师,使学生能有动力学习的首先是兴趣。我们不仅要让学生维持学习的兴趣,还要让本来没有兴趣的学生培养起学习的兴趣。那么,如果能把精读课程的知识点与趣味性结合,提高学生学习的积极性,使精读课程达到一个良好的教学效果呢?     

职业道德与职业指导教学中案例教学法的运用

案例教学法作为一种以学生为教学主体的新型教学方法,对提高课堂活跃度、增强学生学习兴趣有着显著成效。在中职职业道德与职业指导课程的传统课堂教学中,往往容易出现学生对课程不感兴趣、缺乏学习动力的问题。案例教学法的使用有助于促进职业道德与职业指导课程的高效开展。该文通过对中等职业技术学校职业道德与职业指导课程教学现状的分析,比较案例教学与传统教学方法的区别。同时论述案例教学法在职业道德和职业指导教学中的应用,结合教学实际提出案例教学在职业道德和专业指导教学中的具体应用。

PBL与LBL教学法在核医学成人教育中的应用比较研究

目的比较PBL与LBL教学法在临床核医学成人继续教育中对于易混淆知识的教学效果与教学后学生对学科课程的学习兴趣变化。方法针对核医学课程中存在较多易于混淆知识,挑选肝胆与肝血池显像两节教学内容,对我院继续教育学院两个班级分别使用PBL与LBL教学法进行教学,对学生兴趣自主评分与终结性成绩进行比较。结果 PBL教学组学习兴趣自主评分与终结性成绩平均分分别为（6.40±2.60）分与（7.95±2.03）分（总分均为10分）。LBL教学法的对照组分别为（5.22±3.10）分与（7.20±2.20）分。经独立样本t检验比较,可得P值分别为0.002和0.006,两者均于小0.01。可以认为PBL教学组分值均高于LBL教学组。结论 PBL教学组教学后学生对临床核医学学习兴趣及终结性成绩均明显高于LBL教学组。

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
