从教材内容到教学内容——新课程背景下中学物理教师重构教材内容的个案调查

1问题的提出 一种将教师对既定知识的课程内容进行的增减与加工称为教师的“课程重构”，将教师重构后的课程称为“师定课程”．由此，我们将教师对既定的教材内容进行适度增加、删减、置换及加工，整合各种课程资源，最终形成教学内容的过程称之为教材内容重构．     

后现代课程观下的中学物理课堂教学

不同的课程观对课程的理解是不同的．若将课程比喻为“固定的跑道”还是“在跑道上跑的全过程”，则可形象地反映两种不同的课程观——现代课程观和后现代课程观．后现代课程观认为，课程不能片面地理解为静态形式存在的教材，教师和学生在平等的对话和反思中也建构着、生成着课程，课程专家、教材编者是课程开发者，广大师生也是课程的开发者，课程不能脱离实践的主体——教师和学生而单独存在．     

以动能定理为例谈高中物理学科课程方案的建设

新课程的实施,要求物理教师不仅要有教学的意识,更重要的是要有课程的意识.通过学科课程方案的建设,可以有效提高物理教师的课程意识.本文以动能定理为例,从课程目标、课程内容、课程实施、课程评价4个方面来谈物理学科课程纲要的建设,以此来规划本校物理学科的长期发展.     

走进物理新教材的几点思考

新课程对我们广大教师而言，挑战和机遇并存．课程是教育的核心，教师是实现课程目标的关键．教师在面对新一轮课程改革，首先要认真解读、领悟新课程体系中蕴涵的思想，树立正确的教育观念；其次要及时转变角色，确认自己新的教学身份，改变已有的教学行为．     

新课程理念下高师《中学物理教学论》课程的改革与实践

面对全球基础教育改革浪潮，2001年国家教育部颁布了《基础教育课程改革纲要（试行）》，调整和改革基础教育的课程体系、结构、内容，构建符合素质教育要求的新的课程体系．课程改革对中学教师的教育理念、教学行为、知识结构等方面都提出了严峻的挑战．因此，高师院校的《中学物理教学论》系列课程，应积极地调整培养目标、课程结构、课程内容，改革教学方法，培养适应时代发展要求、推进素质教育实施的新型的物理教师．     

"单摆"课程小结

课程小结是教学的重要环节，画龙点晴的课程小结可起到梳理要点，迁移知识，归纳总结的作用．课程小结重在概括精炼，条理清晰，有利学生理性认识的形成．现以单摆为例，浅谈一下教学的课程小结，小结可在学生归纳总结的基础上，由教师再做系统的总结．     

以新课程理念为指导,改革物理实验教学——"改进输液管提示装置"的教学实验设计

1设计思想 目前，国家正在实施新课程改革，目的是培养学生的创新精神和实践能力，培养学生正确的情感态度和价值观。新课程带来了新教育，正确把握新课程的“新”特点，是教师学习新课程、研究新课程、适应新课程、实施新课程、发展新课程的起点．新“课标”取代了过去的教学计划和教学大纲后，课堂教学的改革要求教学方式的转变和教师角色的转变，强调学生学习方式多样化，     

医药类专业大学物理课程现状调查研究

师范院校物理教师教育课程设置改革的探讨

: 本文对国内外3所师范大学物理教师本科教育类课程设置和课程结构比例进行对比, 并以云南师范大 学为例, 分析了物理教师本科教育类课程设置的特点, 提出了师范大学物理教师教育课程改革的4点思考及有关几 点建议.     

物理实验室课程资源的开发

实验是以实验室为基地的教学活动．2002年部颁的普通高中《物理课程标准》（以下简称：新课标）针对实验教学愈来愈凸现的重要性，指出：“实验是物理课程改革的重要环节，是落实物理课程目标、全面提高学生科学素养的重要途径，也是物理课程改革的重要资源．”把“实验”作为“物理课程改革的重要资源”的这一提法，在历次大纲中是前所未有的，给我们从事物理实验教学的教师提出了一个实验教学改革更深层次的要求，所以物理实验室课程资源的开发与利用是课程改革的重要部分．以下是笔者实施新课标以来在实验教学实践中利用开发物理实验室课程资源的一些做法．     

关于"太阳在银河系中所受引力与到银心距离r的关系"的讨论

讨论了银道面内的引力场强分布和太阳在银河系中所受引力与到银心距离r的关系，指出引力场强g并不是与r的平方成反比，这是由于银河系的大小和形状不能忽略造成的．强调了万有引力定律的适用条件．     

On the predictability of the positions of the convergence zones in the ocean

The disagreement between the experimental and calculated positions of the first convergence zone are known from many publications. The most probable cause for such a disagreement, namely, the incorrect specification of the input data for the calculations, is considered. The lack of simultaneity between the hydrological surveys of the region and the acoustic experiments is emphasized. The experimental data obtained by the author in five ocean regions are presented. These data characterize the diurnal variability of the distance from the source to the nearest boundary of the convergence zone. The relations proposed by different researchers for calculating the sound speed from the temperature, salinity, and hydrostatic pressure are analyzed. It is shown that these relations lead to a substantial difference in the estimated depth dependence of the hydrostatic gradient of the sound speed. The position of the first convergence zone is calculated for the propagation conditions determined by vertical temperature and salinity profiles with the subsequent recalculation of these profiles into sound speed profiles by using eight different formulas known from the literature. It is shown that different formulas lead to different values of the distance to the first zone; this difference is substantially greater than that between the calculations and experiment. The necessity of improving the recalculation relations in view of the experimental data on sound propagation in natural oceanic waveguides, including the data on the actual positions of the convergence zones, is emphasized.     

On the calculation of the bremsstrahlung in the region of the plasma frequency

On the basis of the classical theory of radiation produced in incomplete Coulomb interaction, a formula is derived for the coefficient of the bremsstrahlung of fully ionized plasma. In the region of rectilinear approximation a comparison is made with the results of the quantum formula derived from the Born approximation. Furthermore, the influence of dispersion upon the emission coefficient is taken into account; some relations for the region of dispersion are given.     

Dependence of the Intensity of the Spectral Lines and the Composition of the Sample and the Plasma Parameters of the Unipolar Arc

The investigation was made of the dependence of the intensity of Tl, Ga, Mo, Mg, Mn, Sn, Bi, Ni, Zn, Pt and Au spectral lines and the plasma parameters (temperature T, electron concentration n_e, degree of 6 ionnization α) from concentration of lithium additive.     

Extracting the wavefunction of the LSP at the LHC

We consider associated production of squarks and gluinos with the lightest supersymmetric particle (LSP), or states nearly degenerate in mass with it. Though sub-dominant to pair production of color SU(3)-charged superpartners, these processes are directly sensitive to the wavefunction composition of the lightest neutralinos. Exploiting event-shape variables - including some introduced here for the first time - we are able to identify the composition of the LSP by selecting events involving a single high-pT jet recoiling against missing transverse energy. We illustrate the proposed technique on a set of benchmark cases and propose methods for applying these results in more realistic experimental environments.     

Set the controls for the heart of the Sun

In this paper we describe experiments conducted with high-power lasers that are attempting to replicate, for a very short time and in miniature, conditions found in the Sun. Experiments to date have reached conditions in the outer part of the Sun. To reach the Sun's centre requires compression of material to very much greater than solid density and heating to over ten million degrees. To achieve this, a new class of experiments and a new generation of high-power lasers are required.
