<正>中学物理教学大纲明确指出:"物理是一门实验科学。通过演示实验和学生实验,能够使学生理解物理概念和规律的建立与实验的关系,培养学生一定的实验能力。演示实验和学生实验对于培养学生学习物理的兴趣也是十分重要。"由此可见,实验是中学物理教学的一个重要组成部分,它既是物理教学的基础,又是物理教学的重要内容、方法和手段。物理实验能够使学生对物理知识获得具体的、明确的认识,是学生理解概念和物理规律的必要基础。物理实验中有较强的趣味性和探 相似文献

物理是一门以实验为基础的学科,物理实验是培养学生创新能力的最佳途径,要丰富学生的经验和知识离不开物理实验;要培养学生动手、动脑的能力离不开物理实验。因此,认真做好物理实验,改进实验教学方法,对于培养学生创新意识和探究精神具有十分重要的意义。 相似文献

物理教学的主体内容就是要搞好概念和规律的教学,而物理概念和规律的教学必须以实验作引探。因为实验是物理研究的一个重要方法和手段,也是物理教学的重要内容。实验的趣味性可以激发学生学习物理的兴趣,实验的直观性可以加深学生对物理概念和规律的记忆,实验的导向性可以启发学生主动思维,实验的可信性可以强化学生对概念和规律的正确认识。 相似文献

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? 相似文献

汉字的六书,《说文》对“转注”一类,语焉不详。后世学者提及转注,也仅限于许慎所举出的例字。《汉字例说》一文,作者从转注的角度综合考虑,对部分现代常用字作了分析,跟传统的解释有所不同。希望能抛砖引玉,互相切磋,以推进学术研究。 相似文献

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. 相似文献

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. 相似文献

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. 相似文献
