首次对物理学体系进行潜科学分析,探讨了物理学体系的进化过程,分析了物理学在发展过程中两次大潜变的产生原因、主要阻力、潜变标志、潜变的作用和意义以及物理学各个发展时期的潜科学特征．     

物理学史在物理教学中的教育价值

物理学史研究的是物理学发生、发展的规律,它不仅展示了物理学知识的构建过程,而且深刻揭示了物理学研究的科学方法,更能展现科学家们在探求真理过程中表现出的人格魅力和高尚品德。

物理学方法在物理学教学中的意义

讨论了物理学方法的含义;给出了几种特殊的物理学方法;分析了物理学方法在物理学教学中的重要作用;阐述了物理学方法在培养学生创新能力方面的重要意义。指出,物理学知识的发展和物理学方法的发展是同步的。没有物理学方法的发展就没有物理学。物理学家之所以能在物理学的发展上做出重大贡献,除了当时的生产和物理学实验条件外,还与他们发现并正确运用合适的物理学方法有着直接的关系。从认识论的角度来看,新的物理思想、物理过程、物理概念、物理规律等知识的理解,是通过对原有知识的理解和认识及对物理学方法的理解和认识来实现的。物理学方法对于认识主体和认识客体来说,是纽带、桥梁、中介、阶梯。     

能源开发利用中物理学的贡献

从能源科学的发展过程和物理学研究目标出发,分析了物理学的研究成果在常规能源、再生能源以及节能技术上的贡献,重点分析了电磁转化的发现及应用、原子核物理学与核能工程、物理学与能源资源勘探和开发、光学定律与太阳能利用。论述了物理学与能源开发利用的密切关系,认为物理学基础研究与应用的深入发展,可为能源可持续发展做出多方面的贡献,时代对能源利用的高要求,也会反过来开拓、深化了物理学研究的领域,促进物理学的发展。     

《基础物理学中的科学方法》一书简介

在创立、探索物理学的过程中创造了一整套物理学的科学方法。随着物理学的发展,物理科学方法也在不断地发展、完善着。物理学科学方法给了其它自然科学研究工作者许多启示,对科学的发展起了巨大的推动作用,并和这些学科一起,推动了科学方法论的发展,丰富了科学方法论...     

物理教学与素质培育

物理学是研究物质的基本结构、物质最基本、最普遍的运动形式及其相互转化的学科,历来就有“是自然科学之母学科”的说法,物理学课程这一特点,决定了它在学生的素质培育中所能起到的突出作用。 一、科学素养的培育 物理学作为一门学科的形成过程也是近代科学方法的创立、丰富和完善的过程。在物理学的丰富教学内容中,处处闪烁着科学方法论     

物理学史在初中物理教学中的渗透

物理学包含着两类知识体系,一是物理学研究成果即物理概念、规律,二是物理学探究过程即物理学史．物理学史是物理学与其他自然学科、社会学科之间相互交流的产物,既包含丰富的物理内容,又包含科学的研究方法,还包含大量的科学探究过程的成败,是汇集多人的研究成果建立起来的,蕴含着丰富的教育因素．因此,初中物理教学中适当渗透物理学史,给学生展示物理学发展中艰辛与曲折,让学生了解物理发展史中的偶然与必然,经历从生活到物理的认识过程,经历科学探究过程,具有十分重要的意义和价值．     

多媒体教学在医学影像物理学课程中的实践与思考

医学影像物理学课程汇集了物理学、数学、计算机技术、生物学和医学等多门学科,内容抽象复杂、信息量大、教学难度大。将多媒体课件应用于医学影像物理学的教学中,能使抽象的物理过程、陌生的医学知识,在教学过程中给学生以直观、生动具体的图像出现。激发了学生的学习兴趣,提高了教学效率和教学质量。     

“让物理学史教育唤发生命光彩”

物理学史是物理教学的一项重要内容.物理学史作为一门历史科学,它描述物理学发展的历史,再现物理学中各个最重要的,基本概念、基本定律和基本理论的酝酿、产生和发展的过程;着重研究一个时期向另一个时期过渡中,引起物理学观念、物理学研究方法和物理学研究领域发生变化的条件和原因,研究物理学发展的基本规律.

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

The Reader Response Approach to Teaching of English Literature

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context.
