传统的自然地理实践教学模式存在三大问题:一是实验与实习相割裂;二是认识与验证型实验、实习占绝大多数;三是组织模式为:教师讲、学生记笔记、写报告,难以调动学生的积极性。针对以上问题,提出研究型自然地理实践教学模式与组织体系,把实验与实习结合起来;减少验证性实验实习,以问题为导向,将专题研究与实践教学相结合;改变教师单纯讲授的传统教学模式为以学生为主体的研究型实践教学体系,培养和提高学生的实践能力和创新能力。 相似文献

目前大学公体排球课的教学大多采用传统的教学模式——以技能教学为主,以教师为核心的课堂教学模式,忽视了学生的主观能动性.在这种教学模式下,学生极易产生厌学情绪.互动创新与传统教学模式相结合的教学模式是新课改的一种尝试,与传统教学模式在师生关系、课堂组织形式和教学功能上都有着很大的区别,尤其在大学公体排球课中的具体应用,能够激发学生体育的兴趣,开发学生的体育潜能,发展学生的体育活动能力.两种教学模式相结合对提高大学公体排球课的教学质量,更好地彻底落实"以学生为主、健康第一,学一门特长技术、终身体育"的指导思想有着重大的意义. 相似文献

依据长江师范学院"化工工艺学"课程教学方法的探索与实践,提出了"参观了解-理论学习-模拟仿真-实验(实训)操作-工厂见习"交替进行的化工工艺学理论及实践相结合教学新模式.在这种新教学模式下,学生不仅能更充分地理解理论知识,熟练地掌握实验操作技能,深入了解工厂实际,而且能把理论与实践真正地结合起来,教学质量得到了明显提高. 相似文献

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. 相似文献

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. 相似文献

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。 相似文献

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. 相似文献

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- 相似文献

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- 相似文献

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 相似文献
