教学要适应时代的发展,教学内容要跟踪现代科学技术,不断研究和调整好现代科技与基础知识的连接点及生长点,从而培养现代化的创新人才。以诺贝尔物理奖为载体命制的相关试题,着力寻找与物理基础知识相联系的部分,力求反映现代科学与技术的成就,注重情感包装,使题目具有很强的亲和力,在题目与学生之间创设一种触及学生情感和意志领域的情景,有意识地把学生引入一种解题的最佳心理状态。下面举例试之。一、激光制冷原子例1 原于在不停地做热运动,为了能高精度地研究孤立原子的性质,必须使他们几乎静止下来并能在一个小的空间区域停留一段时间,为此,美国华裔物理学家朱棣文首创了激光制冷和捕捉气体原子的方法,从而荣获1997年的诺贝尔物理奖。其原理如下:在一个真空室内,一束非常准直
The teaching should adapt to the development of the times, and the content of the teaching should follow modern science and technology, continuously research and adjust the connection points and growth points of modern science and technology and basic knowledge, so as to cultivate modern innovative talents. The questions related to the Nobel Prize for physics as a carrier are focused on finding the parts related to the basic knowledge of physics, trying to reflect the achievements of modern science and technology, emphasizing emotional packaging, and making the subject have a strong affinity, in terms of topics and students. Create a situation that touches the field of students’ emotions and will to consciously introduce students to a best mental state of problem solving. Here’s an example to try it. First, the laser refrigeration atom 1 is in constant heat movement. In order to be able to study the properties of isolated atoms with high precision, it is necessary to keep them almost stationary and stay in a small space for a certain period of time. For this reason, the United States Chinese physicist Zhu Yuwen first won the 1997 Nobel Prize for physics for his method of laser cooling and capturing gas atoms. The principle is as follows: in a vacuum chamber, a bunch of very collimated
