科学课教学中学生科学素养的培养

在中学科学教育中培养学生的科学素养,有助于学生从整体上认识自然和科学,引导学生认识科学的本质,正确理解科学、技术与社会的相互关系,全面体现科学教育的价值.目前各国都十分重视科学教育,提高学生的科学素养成为科学教育的核心目标.我国中学科学课作为培养中学生科学素养的主阵地应采取各种措施提高中学生的科学素养.本文从三个方面论述了科学素养教育的兴起、内涵及培养方法.     

大学生科学素养与通识教育关系的实证分析

基于对科学素养和通识教育的学理梳理,采用改进的基本科学素养量表(TBSL)对我国大学生科学素养进行分析.结果发现,修读科学知识与科学精神方面的课程和参与通识教育理念下课外学生活动对学生的科学素养的培养有显著影响,而学生整体课程学习成绩水平对学生科学素养培养没有进行测量,并进一步运用方差分析和回归分析进行通识教育对大学生科学素养影响的实证分析.因此,大学生科学素养教育只有纳入以人的全面发展为目标的通识教育体系中才有可能真正实现科学素养的培养目标.     

揭示思维过程,培养科学思维能力

生物实验教学可以激发学生的学习兴趣,帮助学生获得各种实验技能.有利于培养、提高学生的观察、操作、分析、归纳、总结、应用能力,还有利于培养、提高学生的创新能力和审美能力,而这些恰恰都是学生必不可少的科学素养;同时还有助于培养学生严谨的科学态度,实事求是的治学精神.生物实验既是学生探索科学的重要方法,又是推进素质教育的重要途径,对提高学生的科学素养起着至关重要的作用.     

在校大专生科学素养的调查与探析

采用2003年我国公众科学素养调查问卷对在校大专生进行调查研究.结果表明:我国大专生尤其是文科生和艺术类学生科学素养水平不高;科学知识比科学方法掌握得好,但对高新科学技术知识了解较少;大多数学生对科学技术发展持积极的态度,但也有相当部分学生还缺乏对伪科学和封建迷信活动的辨别和判断能力.培养大专生的科学素养的主要途径是构建科学合理的课程体系和营造良好的科学素养教育环境.

当前是科学飞速发展的时代，科学素养的培养已成为培养新型人才的必然要求。大学是素质教育的基地，科学素养的培养是大学素质教育的重要方面。由于种种原因，我国当前大学生科学素养总体水平不容乐观，这就要求我们必须把提高大学生科学素养作为培养新型人才的标准，在教学中采取多种方法提高学生的科学素养。     

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.     

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
