改革兽医药理学实验课,培养学生综合实验素质

实验教学是人才培养的重要组成部分,实验教学改革是教学改革的重要环节。以四川农业大学兽医药理学实验课程为例,以专职实验教师的视角分别从如何提高学生学习积极性、如何增强学生分析解决问题的能力、如何改善学生实验室素养、如何评价教师教学效果等四个方面讨论了几点心得。     

生物技术创新实验教学体系的建构与实践

生物技术创新实验教学体系以实验技能分类为主线,优化整合实验内容,将生物技术实验教学划分为五个模块:生物培养技术,生物显微技术,生化样品的制备与分析,分子生物学与基因工程,生物技术大实验.教学实践结果表明,生物技术创新实验教学体系调动了学生实验的积极性,增强了学生自主实验的能力,增强了分析问题和解决问题的能力,使学生从更深层次上理解了实验的内在联系.     

基于微视频的计算机网络工程实践教学体系

针对学生实验动手能力弱、学习能力差异大和教师课堂讲授时间短等现实问题,将网络工程课程专业知识点分解,构建网络工程微视频教学网站.不同于传统的视频教学,利用微视频时间短、单一知识点讲解演示、目标明确等优点,通过串接各个知识点,构建微视频知识群,有效解决实验课堂上学生学习积极性不足、依赖教师手把手指导、教师工作量大等问题,激发学生学习热情,增强学生动手能力和应用能力;实现教与学的有效互动,提高实验课程的教学效果,为工科实践教学改革的探索与实践提供有价值的参考.     

注重学生能力与相互配合能力的培养

学生在学校期间不仅要学好每门功课的基础知识,也要注重动手能力的培养.目前在校大学生的动手能力培养是靠学校提供的实验来达到目的,在实验环节中,教师注重验证实验和学生个人的动手能力,而忽视学生之间相互配合能力的培养.对此我们在微机原理实验中增加了学生相互配合能力的培养,从中得到一点体会.我们认为这种教学方法是可行的,通过这种训练,学生不仅能在基础知识方面得到强化,也能培养学生的动手能力,同时也加强相互配合能力的培养,增强学生相互之间协作的精神.     

无机化学实验教学中PBL教学法的应用及评价

PBL教学法是以问题为基础的教学方法,它能提高学生的学习兴趣和积极性,培养学生自主获取知识的能力,训练学生的思维力,增强其综合运用知识的能力。传统的无机化学教学模式是以教师讲授为主,学生被动地重复实验,为提高无机化学实验课的教学质量,可以尝试在无机化学实验课的教学中采用PBL教学法。     

简析大学英语教学中教师的角色

现阶段大学英语教学目标是要培养学生的英语综合应用能力,特别是听说能力,使他们在今后的工作和社会交往中能用英语有效地进行口头和书面的信息交流,增强其自主学习能力.随着以学生为中心、以教师为主导的大学英语教学模式的逐渐确立,教师应该重新定位自己的角色,扮演好引导者、组织者、参与者及观察者等.

创新能力是当代大学生应具备的重要能力,在运动生理实验教学中培养学生的创新能力需要增强教师的责任感和使命感,提高教师的创新精神,端正学生对实验课程的认识,并积极推进实验教学的改进,才能更好地培养学生创新意识和创新能力.     

大学土木工程实验室开放管理对本科教学的促进作用分析

在各级各类高校实验室建设中,对实验室开放管理都有明确的要求。以山东省土木工程防灾减灾重点实验室开放管理为例,结合土木工程学科特点,从学生和教师两个实验主体详细分析了实验室开放对本科教学的促进作用。通过分析得出,通过多种形式渠道的实行实验室开放,可以全方位促进学生各种能力的培养,也可以促进教师责任心提高,提高教师实验水平,增强实验教师队伍的建设。     

浅谈技校实验教学的改革与学生动手能力的培养

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
