基于硅MEMS(micro-electromechanical systems)加速度传感器体积小(微米量级)、工作原理较抽象、课堂教学接受较困难等问题,构建了硅MEMS加速度传感器教学实验平台。该实验平台主要由加速度信号发生装置、高性能石英振梁加速度传感器、MEMS加速度传感器芯片、A/D转换电路、单片机数据采集及处理电路、液晶显示装置等组成。加速度信号发生装置提供不同的加速度信号。高性能石英振梁加速度传感器用于对MEMS加速度传感器的测试结果进行比对。测试结果表明,该实验平台性能良好,能够满足实验要求。该实验平台不但强化了对学生动手能力的培养,体现了实验教学与课堂教学的结合,也为传感器技术及应用、误差理论与数据处理等课程提供了重要支持。 相似文献

在信息技术迅猛发展的今天,数字化实验已经走进初中物理课堂,教师借助计算机、传感器、数据采集器等辅助配套教具,针对传统的物理实验模式进行创新、改进,不仅可以清晰、直观地反映出实验原理与实验现象,并且能够有效激发学生的学习兴趣,使学生的科学探索欲变得更加强烈。基于此,在物理教学中,教师应当充分发挥数字化实验的应用优势,通过对力学、电学、热学数字实验的探索,为学生构建集趣味性、科学性、引导性、启发性于一体的高效课堂。 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

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

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. 相似文献
