如何提高学习数学的兴趣

爱因斯坦说：“兴趣是最好的老师”。学生的求知欲源于兴趣，有了兴趣才会产生探索新知的欲望，才会激发学习数学的热情，数学教学就是要点燃学生对数学学习热情的火把，培养他们的学习兴趣。学生有了兴趣，才能产生学习的动力，才能积极地畅游数学知识的海洋，才能品味学习数学的情趣和价值，因此，在数学教学中激发学生的学习兴趣，就显得更为重要了。如何激发学生学习数学的兴趣呢？该文浅谈自己的几点看法。     

高中数学教学中培养学生的学习兴趣策略

对于大多数的高中学生来说,很多人学习数学是为了高考而学,所以对于数学根本就没有兴趣。所以老师在讲授数学知识时,学生们不会提起注意力学习数学,老师在教学过程中也会遇到很多困难。所以对于老师来说,首先需要提高学生的学习兴趣,如果有了学习数学的兴趣就可以转化为内动力推动学生主动学习数学,产生兴趣之后,学生才可以在课堂上得以放松和老师积极地探讨数学问题。     

兴趣是最好的老师

“好的老师不是在教数学，而是激发学生自己学数学”。兴趣来源于目的，兴趣来源于人的求知天性，兴趣来源于喜悦。学习活动是充满挑战性的活动，学习中充满着种种困难，如果这个困难被克服，就会产生一种喜悦，对学习产生兴趣。如何激发学生学习数学的兴趣，本文从六个方面进行阐述。     

激发学习兴趣提高学习效率

数学教学成功与否,一个重要的因素是学生对学习数学是否有兴趣.爱因斯坦说过,兴趣是最好的老师.浓厚的学习兴趣可以使人的大脑处于最活跃的状态,能够最佳地接受教学信息.浓厚的学习兴趣,能有效地诱发学习动机,促使学生自觉地集中注意力,全身心地投入学习活动中.而如果缺乏兴趣,那么学生就会对学习感到枯燥乏味.为此,要提高数学教学质量,培养学生对数学的学习兴趣,也就显得尤为重要.怎样培养学生对数学的学习兴趣呢?本人结合自己的教学实践,谈几点体会:     

巧设悬念，激发兴趣

兴趣是最好的老师。在数学教学中，巧设悬念是激发学生学习兴趣的一种非常有效的途径，本文结合自己的教学实践经验谈如何在课堂教学中，通过设置悬念，激发学生学习兴趣的一些做法和体会。     

数学后进生的问题与对策

后进生是每个教学班都存在的问题,只要老师转化教育观念,关心爱护学生,指导学生树立正确的学习目的,调动学生的学习积极性,激发学生的学习兴趣,培养学生的创新意识,提高学生数学的思维能力,形成数学思想和方法,这样后进生也是会转化为优秀生的。本文就数学后进生存在的问题和数学教学中后进生的转化方法提出了自己的看法。     

怎样提高学习数学的兴趣

俗话说＂兴趣是最好的老师＂,有了兴趣就有了学习的动力,有了动力学生才想学、爱学、乐学。单调的学习数学知识,枯燥无味,很难激起学生学习的积极性。怎样才能提高学生学习数学的兴趣呢？我在教学实践中从以下几方面使学生对数学学习产生了浓厚的兴趣。     

如何提高学生学习数学的兴趣

有的学生说数学枯燥无味；有的学生说数学奥妙无穷。为什么学生对数学的态度会有如此大的反差？关键是个人学习兴趣的问题。兴趣是最好的老师，兴趣也是学生渴求获得知识、探索真理而带有情绪色彩的意向活动，是推动学生认真学习的一种内驱力。因此，在教学中，切实提高学生学习数学的兴趣，是非常重要的。

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.     

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.     

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.     

An Index mechanism for multi-scale view in spatial databases

There are numerous geometric objects stored in the spatial databases. An importance function in a spatial database is that users can browse the geometric objects as a map efficiently. Thus the spatial database should display the geometric objects users concern about swiftly onto the display window. This process includes two operations:retrieve data from database and then draw them onto screen. Accordingly, to improve the efficiency, we should try to reduce time of both retrieving object and displaying them. The former can be achieved with the aid of spatial index such as R-tree, the latter require to simplify the objects. Simplification means that objects are shown with sufficient but not with unnecessary detail which depend on the scale of browse. So the major problem is how to retrieve data at different detail level efficiently. This paper introduces the implementation of a multi-scale index in the spatial database SISP (Spatial Information Shared Platform) which is generalized from R-tree. The difference between the generalization and the R-tree lies on two facets: One is that every node and geometric object in the generalization is assigned with a importance value which denote the importance of them, and every vertex in the objects are assigned with a importance value,too. The importance value can be use to decide which data should be retrieve from disk in a query. The other difference is that geometric objects in the generalization are divided into one or more sub-blocks, and vertexes are total ordered by their importance value. With the help of the generalized R-tree, one can easily retrieve data at different detail levels.Some experiments are performed on real-life data to evaluate the performance of solutions that separately use normal spatial index and multi-scale spatial index. The results show that the solution using multi-scale index in SISP is satisfying.     

海南岛地体及其毗邻陆缘晚中生代—新生代古地磁研究和构造演化

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。
