以赛促教,让物理教学改革成果惠及学生——全国高等学校物理基础课程青年教师讲课比赛的探索实践

由教育部高等学校大学物理课程教学指导委员会、教育部高等学校物理类专业教学指导委员会和中国物理学会物理教学委员会共同主办的＂高等教育杯＂全国高等学校物理基础课程青年教师讲课比赛,在高校物理教学界产生广泛影响。文章对当前高校物理教学形势和背景作了简要介绍后,重点说明比赛的源起、理念、组织原则、工作思路和其他相关的探索与实践,文章还总结了比赛效果并提出对今后比赛的展望,希望其中一些经验和做法能得到借鉴和推广,同时获得更多青年教师的关注、建议及反馈.     

厚积薄发,团队互助,以竞赛成果促教学创新——首届全国高等学校物理基础课程青年教师讲课比赛参赛感想

我有幸参加了在四川成都举办的第一届全国基础物理课程教学青年教师讲课比赛.这次比赛使我认识到了自己教学中的不足,加深了对大学物理课程的理解和把握,而对其他高校青年教师的讲课观摩以及赛前赛后的交流沟通,也为我们提供了许多可供学习和借鉴的教学经验,为未来的教学工作提供了思索和拓展的空间.从这次比赛我体会到：（1）厚积薄发,扎实的物理基础和系统的科研培训是讲好课的基础;（2）团队互助,集体的力量带动青年教师稳步成长;（3）以赛促教,讲课比赛快速提升青年教师教学水平.     

Passion for precision.

Optical frequency combs from mode-locked femtosecond lasers have revolutionized the art of counting the frequency of light. They can link optical and microwave frequencies in a single step, and they provide the long missing clockwork for optical atomic clocks. By extending the limits of time and frequency metrology, they enable new tests of fundamental physics laws. Precise comparisons of optical resonance frequencies of atomic hydrogen and other atoms with the microwave frequency of a cesium atomic clock are establishing sensitive limits for possible slow variations of fundamental constants. Optical high harmonic generation is extending frequency comb techniques into the extreme ultraviolet, opening a new spectral territory to precision laser spectroscopy. Frequency comb techniques are also providing a key to attosecond science by offering control of the electric field of ultrafast laser pulses. In our laboratories at Stanford and Garching, the development of new instruments and techniques for precision laser spectroscopy has long been motivated by the goal of ever higher resolution and measurement accuracy in optical spectroscopy of the simple hydrogen atom which permits unique confrontations between experiment and fundamental theory. This lecture recounts these adventures and the evolution of laser frequency comb techniques from my personal perspective.
