建构数学课堂自主学习模式

学会学习，使学生具有适应终生学习的基本技能和方法，是新一代基础教育课程的目标之一。“自主学习”的课堂模式，是指学生在学习活动之前能够对学习进展、学习方法，作出自我监控、自我反馈和自我调节，在学习活动之后，能够对学习结果进行自我检查、自我总结、自我评价和自我补救的学习模式。那么如何建构数学课“自主学习”课堂模式呢？

谈大学生网络学习的积极作用

在大学校园内，网络学习作为信息时代的新生事物，已经被当代大学生所接纳，成为大学生课余学习的主旋律。网络学习具有大学生传统学习中不可替代的优势，必然对大学生的学习兴趣、学习方式、学习能力、学习效率等产生积极的作用。     

教会学生学习——谈学生自主学习习惯的培养

自主学习是指个体自觉确定学习目标、制定学习计划、选择学习方法、监控学习过程、评价学习结果的学习。培养学生的自主学习习惯非常重要，是全面实施新课程标准的一个重要因素，是实现教育本质的一条重要途径，是契合教育发展规律的一种学习方式，是回归学习真面目的一种方法。     

培养初中生自主学习能力探析

学生自主学习是一种自律学习，是一种主动学习，因为每一个学生都是一个独立的人，学习是学生自己的事情，这是教师不能代替也是代替不了的，教师只是起指导作用，每一个学生都有一种独立的要求，除有特殊原因外，都有相当强的独立学习能力，现行教学改革要求改变单纯接受式学习，讲究从“一刀切”教学向关注个体差异的教学转变，强调发现学习、探究学习、研究学习、自主学习显得更加重要。正因为如此，培养学生自主学习数学的能力显得十分重要。     

浅谈"现代学习方式"

“学习方式”较之于“学习方法”是更为上位的东西，二者类似战略与战术的关系：学习方式相对稳定，学习方法相对灵活，学习方式不仅包括相对的学习方法及其关系，而且涉及学习习惯、学习意识、学习态度、学习品质等心理因素和心灵力量。传统的学习方式把学习建立在人的客体性、受动性、依赖性的一面上，从而导致人的主体性、能动性、独立性的不断销蚀。什么是“现代学习方式”?现代学习方式不是特指某一具体的方式或几种方式的总和，从本质上讲，现代学习方式是以弘扬人的主体性为宗旨，以促进人的可持续性发展为目的，由许多具体方式构成的多维度、具有不同层次结构的开放系统。认识和把握现代学习方式的本质特征是我们创造性地引导和帮助学生进行主动的、富有个性的学习的重要保证。“现代学习方式”既是全面实施素质教育的需要，更是素质教育培养多功能型人才、创新人才，提升学生社会实践能力和就业技能的需要。

疫情防控常态化下在线学习成为高职学生的重要学习途径。以计划行为理论为依据，在行为态度、主观规范、感知行为控制、行为意向、行为五个变量基础上引入学习倦怠变量，探讨高职学生在线学习倦怠对学习行为影响的机理。方法：在对高职学生在线学习调研的基础上，建立AMOS结构方程模型，探讨学习倦怠对高职学生在线学习行为的影响过程及关系。结果：学习倦怠受到主观规范负向的显著影响，行为态度受到学习倦怠的负向显著影响，感知行为控制受到学习倦怠的正向显著影响，学习行为意愿受到感知行为控制的负向显著影响。建议：通过优化在线学习管理，改进教学策略，提高社会支持和增强高职学生效能感等几项措施，降低高职学生学习倦怠，提升高职学生在线学习意愿，提高在线学习质量。     

新课程标准下的数学教学方法探索

新课程标准下的数学学习不应只限于接受、记忆、模仿和练习，还应倡导阅读自学、自主探索、动手实践、合作交流等学习方式，为形成积极、主动、多样的学习方式进一步创造有利条件，以激发学生的学习兴趣，鼓励学生在学习过程中养成独立思考、积极探索、自己构建知识的习惯和积极主动的学习方式，培养他们的学习能力，发展他们的创新意识。     

研究性学习探微

研究性学习倡导学生由被动、接受式的学习转向主动、探究式的学习。对于学生来说，这是一场学习方式的根本转变，这种转变为学会学习乃至终身学习打下重要的能力基础。学生学习方式的转变，要求教师教育观念和教学行为也必须发生转变，教师将成为学生学习的参与者、合作者、引导者和促进者，师生教学相长，共同发展。     

试论化学研究性学习课题的选择

研究性学习是一种全新的教学方式，它有助于学生主动探究、自主学习，化学研究性学习有利于培养学生的创新能力、实践能力、问题意识、合作意识以及关注化学与自然、社会、生活的联系，研究性学习的选题是在化学教学中实施研究性学习的关键，是化学研究性学习实施的前提，课题的选择必须符合研究性学习的开放性、探究性、实践性，遵循问题性、可行性和创新性原则，化学研究性学习课题应从化学课堂教学，化学实验教学，化学与自然、生活、社会的联系以及化学学科发展前沿中选择。     

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.

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.     

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-
