源于地区中小学美术课青年教师教学竞赛的思考

美术教育是学校实施美育的主要内容和途径之一;是学校实施美育最有效最重要的手段之一,是培养学生全面发展所不可缺少的重要环节.本文针对地区基础美术教育的现状和实际,阐述了美术教育在学校教育中的重要性,就新形势下尽快改变地区基础美术教育薄弱、落后的现状作初步探讨.     

美术教育与人的创造能力的培养

《中国教育改革和发展纲要》明确指出 :“基础教育是提高民族素质的奠基工程。”然而我国完备的学校美术教育体系 ,还没有建立。目前 ,尤其是中小学校美术教育的观念和重视程序 ,还很不尽人意。在强调科教兴国、重视素质教育和努力构建 2 1世纪的学校教育体系的语境中 ,关注和研究中小学美术教育的重要性 ,是学校美术教育学科建设最急迫、最重要的问题。中小学美术教育是素质教育的重要组成部分 ,是为国家、为社会、为中华民族培养和发现艺术人才 ,提高全民艺术修养的重要手段与途径。其中学生在校学习期间 ,特别是初中阶段的美术思想、美术…     

浅析中小学美术教育课程建设与学生智力发展

受到应试教育的影响，我国中小学美术教育在对学生进行美育和促进智力发展方面的功能没有完全发挥。本文从如何加强美术课程建设、丰富教学内容和增强感受性训练等方面进行了论述，提出要充分认识到学校美术教育与学生智力发展之间的关系，要在实践中充分利用好美术教育这一有效的方式和途径，努力发展学生的智力，以提高学生的整体素质。     

农村中学开展美术教学经验之谈

美术课是义务教育的一门必修的艺术教育课程,美术教育是美育的一个重要组成部分,是对学生进行美术教育,促进智力发展和进行思想品德教育的重要途径。由于种种原因,农村美术教育相对于城市来说是滞后的,这不仅需要社会、学校的努力,更需要我们一线的美术教师为之付出努力,来发展农村的美术教育。一     

浅谈农村初中如何培养学生的美术兴趣

美术教育是人类重要的文化教育活动，是学校艺术教育的重要组成部分。我国九年义务教育初中阶段的美术课，是实施美育的重要途径。学校开展美术教育，是以教育为手段，向学生传授一定的美术知识和培养必要的技能，发扬和传播美术文化，以美术为媒介，培养学生的道德情操和审美能力，发展智力和创造力，获取一般教育学意义的功效。但是，从目前的状况来看，广大农村地区的中学美术教育，     

乡土艺术融入农村中学美术教育初探

美术教育是实施美育的重要途径,它对陶冶情操、启迪智慧、促进学生全面发展具有不可忽视的重要作用。近几年由于国家对素质教育的强调和对美育的重视,使得中国的学校美术教育目前正处于一个非常好的发展时     

高师美术教育中学生素质的培养

高等师范院校的美术教育,培养着未来的中小学美术教师。中小学美术教育是一种人文教育,它对陶冶学生情操,提高审美能力,完善个性发展,促进学生健康成长具有重要意义。中小学的美术课程,是学校实施美育最重要,最直接的必修艺术课程。一个优秀的中小学美术教师不仅仅是美术知识与技能的简单传授者,他同时担负着教书育人的重任。培养高素质的美术教师是高等师范院校美术教育的神圣职责。     

谈美术课堂教学中的情感渗透

0引言 美术课是义务教育阶段的必修课,对于陶冶学生情操,启迪学生智慧,促进学生全面发展,具有重要作用。在提倡素质教育的今天,美术教育越来越受到重视。但由于种种原因,农村的美术教育相对滞后于城市,这需要社会、学校等多方面的努力,更需要一线美术教师为之付出劳动,让学生在课堂上体验绘画创作的激情,感受美术课的审美情趣,提高学生的兴趣。笔者根据教学实践中的感受,提点陋见,敬请商榷。     

浅议中国美术教育的近代化进程

中国古代美术教育模式是师徒传授加自学为主导的。在中国历史进入宋代后,具有学校性质的画院教育萌生了近代性质的美术教育形态,但却没有重大发展。鸦片战争以后西学的东渐,催化了中国美术教育的近代变革,其主要特征是美术教育普通化和教育模式学校化。     

浅谈小学美术教育

基础教育是提高民族素质的奠定工程。然而，美术教育的观念与教学内容选择，还比较滞后。或者说，有的还过多的是依赖于经验、或是根据某些经验基础上的权威之指令而行事。在强调科教兴国、重视素质教育和努力建构21世纪的学校教育体系的语境中，关注和研究学校美术教育的观念与教学内容选择的原则，是有着学校美术教育学的学科建设价值与意义的。那么，现在我也来谈一谈小学的美术教育。     

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.     

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.     

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.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.

橡胶颗粒沥青混合料低温抗裂性试验研究

以AC-13级配为基础,将橡胶颗粒代替部分集料掺入混合料中,以低温弯曲试验为评价方法对不同橡胶颗粒掺量下沥青混合料的低温抗裂性进行研究,并引入应变能密度值对混合料的低温抗裂性进行综合评价.试验结果表明:橡胶颗粒沥青混合料试件的破坏微应变均超过2 300,满足冬寒区的技术指标;无论是否掺加橡胶颗粒,随着温度的下降,沥青混合料破坏时的最大弯拉强度增大,弯拉应变降低,劲度模量增大;弯曲应变能密度在胶粒掺量为1%左右时具有较大的弯曲应变能密度值,此时橡胶颗粒沥青混合料具有较好的低温抗裂性.     

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。     

Quantitative trait loci （QTLs） for quality traits related to protein and starch in wheat

Quality traits in wheat （Triticum aestirum L.） were studied by quantitative trait locus （QTL） analysis in a recombinant inbred line （RIL） population, a set of 131 lines derived from Chuan 35050 × Shannong 483 cross （ChSh）. Grains from RILs were assayed for 21 quality traits related to protein and starch. A total of 35 putative QTLs for 19 traits with a single QTL explaining 7.99-40.52% of phenotypic variations were detected on 10 chromosomes, 1D, 2A, 2D, 3B, 3D, 5A, 6A, 6B, 6D, and 7B. The additive effects of 30 QTLs were positive, contributed by Chuan 35050, the remaining 5 QTLs were negative with the additive effect contributed by Shannong 483. For protein traits, 15 QTLs were obtained and most of them were located on chromosomes 1 D, 3B and 6D, while 20 QTLs for starch traits were detected and most of them were located on chromosomes 3D, 6B and 7B. Only 7 QTLs for protein and starch traits were co-located in three regions on chromosomes 1D, 2A and 2D. These protein and starch trait QTLs showed a distinct distribution pattern in certain regions and chromosomes. Twenty-two QTLs were clustered in 6 regions of 5 chromosomes. Two QTL clusters for protein traits were located on chromosomes 1D and 3B, respectively, three clusters for starch traits on chromosomes 3D, 6B and 7B, and one cluster including protein and starch traits on chromosome 1D.     

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.
