让个性在课堂教学中飞扬——浅谈中学物理教学中学生个性的培养

信息时代、知识经济时代期待着大批创造型人才的出现,这就对学校教学提出了更高的要求.作为教学的主阵地--课堂教学,如何让学生的个性和创造性潜能得到充分的发展,成了摆在每位教师面前无法回避的任务.     

让学生主动思考和经历过程——对新课标下"在流体中运动"课程的分析和思考

教科版初中物理第一、二册改变了传统教材中只单纯传播知识的功能，增强了趣味性和探索性，注重了培养学生的创新能力；降低了知识的难度，处理问题时以学生的接受能力为基点，注重由易到难、由简到繁，从而更符合学生的认知规律．章节编排在整体上体现了以学生为主体的教学思想，在培养学生的创新意识和创造能力方面能起到积极作用．每节内容的展开都渗透有“过程与方法”的教学．     

为学生打开自主学习的空间--一个高中物理教学案例与思考

现在，整个教育界都在提倡创新教育和自主探究式学习．笔者曾经尝试着在课堂上渗透让学生自主学习的思想，努力创设情景给学生多一些创新的机会，允许并鼓励他们在课堂上提出自己的看法．但课堂教学，特别是在目前仍受考试压力影响的高中课堂中，教师和学生依然面临着升学压力．无奈的现实很难在课堂上落实这些“理念”．毕竟学生这么多、课时这么少、教学任务又如此之重，作出一个教学决定又要考虑方方面面的因素，     

学生独立思考能力的培养

在近几年物理高考考试说明中明确指出“把能力考核放在首要位置”，为了提高学生素质，提高物理教学质量，在教学中必须培养学生的能力．而在物理高考中所要考查的能力有五种，笔者认为在中学物理中首先要培养学生的独立思考能力．不善于独立思考，各方面具体能力的培养将受到极大影响，也不可能有效地运用各方面的能力，独立地去分析解决问题＋如一些学生在解题时不会独立处理问题，这不是由于题目做得少，而是平时缺乏独立思考能力的训练和习惯．高中物理教学中怎样培养学生的独立思考的能力呢？     

Stopping of Fast Structural Ions in a Substance by Means of Excitation of Their Own Electrons

Russian Physics Journal - The paper considers the theory of stopping of fast structural ions in a substance. Within the eikonal approximation, it develops a non-perturbative method for calculation...     

如何指导学生掌握物理概念

物理概念的掌握是对已有物理概念的一个有组织的学习过程,它虽不像科学史上物理概念的建立那样曲折漫长,但都是认识客观世界的过程,都得遵循相同的认知规律:从感性(感觉、直觉、表象)通过分析、综合、抽象、概括到理性认知.也就是说,学生对物理概念的掌握也需要经历从具体到抽象、从感性到理性、从模糊到精确、从简单到系统的发展过程.在中学物理教学过程中,如何通过教学设计来让学生经历上述过程有效地掌握物理概念呢?现就高中物理教学实践过程谈谈指导学生掌握物理概念的策略.     

Subsystem Dynamics of an Anisotropic Two-Qubit Heisenberg XYZ Chain Coupled Independently to Their Own Environments

We consider a composite system:an anisotropic two-qubit Heisenberg XY Z chain coupled independently to their own environments.We take one of the qubit as the subsystem and the other qubit as an auxiliary qubit,and then the subsystem we concern can be considered to be coupled to a structured bath(auxiliary qubit + environments).Based on this,we study the non-Markovianity of the subsystem dynamics and show how the subsystem dynamics can be changed by manipulating the intensity of the qubit-qubit couplings or the anisotropy parameter.Moreover,we show how entanglement between the subsystem and the structured bath can be affected by the properties of the structured bath and the magnetic field.     

Integration of Hybrid Dendrimers and Their Generations for Modulated Spatio-Temporal Action

Hybrid dendrimers constitute a unique class of well-defined complex architecture featured with a central domain and bifurcated branches with two different dendritic sequences for their atomic configuration and functional groups at the periphery. This review article pioneers the field of new hybrid dendrimers using different generations by nanoconjugation with metals, carbohydrates, nucleotides, proteins/peptides, carbosilane, urea, silica, stem cells, guanidine, etc. The smart dendrimers contain desirable electrical, magnetic, optical, and biological attributes to increase surface area, monodisperse behavior, dose reduction, dissolution, permeability, long-term stability, and significant decrement in nanotoxicity studies. The higher encapsulation of lipid soluble and insoluble moieties explores an excellent platform for the delivery of drugs (ibuprofen, indomethacin, etc.), nucleic acids (oligonucleotide, siRNA, and aptamer), genetic materials , and chemical diagnostic agents (gadolinium chelates and superparamagnetic iron oxide particles) for imaging. Owing to their flexibility in structural adaptability, different health conditions like glaucoma, inflammation, microbial infection, neurodegenerative problems (Alzheimer's disease and Parkinsonism), and cancer are benefited using such long-lasting drug delivery. Advancements in molecular engineering techniques, 3D printing, artificial intelligence, robotic, green synthesis, and microwave-assisted methods aid in the development of economically reliable and personalized pharmaceutical hybrid dendritic systems resembling antibodies, globular proteins, stem cells, enzymes, and genetic materials.     

Elemental Analysis of Tea Leaves (Camellia Sinensis) and Their Own Soils at Eastern Black Sea Region in Turkey

People consume tea brewed from the leaves of the Camellia sinensis plant for about 50 centuries. Health benefits of the tea have been investigated for about three decades. Especially green tea shows antitoxic and lots of properties with its determined ingredients. Turkey is not only the one of the best consumer and but also good producer of the tea as being 5 th producer all over the world. It grows eastern region of the Turkey and high quality tea is imported and exported. To have quality tea, grooving soils are also crucial. In the current research, Tea leaves and their own grown soils were collected from 20 stations where the most tea producer cities as Trabzon, Rize and Artvin tea fields of the eastern of Black Sea Region in Turkey. The cultivated tea and their own grown soil samples were analysed by using EDXRF Spectrometry. In the soil samples, the elements Mg, Al, Si, P, S, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Sr, Ba, Pb on percent level and the elements Mg, Al, Si, P, Cl, K, Ca, Ti, Mn, Fe, Ni, Cu, Zn and Sr in the tea leaves were detected by using SKRAY 3600-EDXRF.and also the obtained data were evaluated with the Kriging interpolation of geostatistical method. Element content were investigated in the soil and tea samples according to the geological situations and also the relation of elemental difference between the tea and the own grown soil. Pb/Zn ratio was also anaysed in the samples.     

物理知识系统化和整体化的引导

在物理教学中,教师要认真钻研教材,统观教材的全局,引导学生应用知识规律理清主线,掌握知识的整体和知识之间的内在联系,并使之系统化.完成知识系统化和整体化是培养学生的各种能力的基础.1 发挥教师的主导作用在于引导和帮助 完成知识的系统化、整体化,不但在复习课中而且在讲授新课中都要注意新旧知识的联系,使之贯串在整个教学过程中.
