在新一轮课程改革实施过程中,高中阶段由于学生初涉狭义相对论,容易混淆“观测”和“观看”这两个概念,甚至在有些按新课程标准编写的教材中,也混淆了这两个概念,从而使高中教师和学生对“观测”和“观看”的理解产生障碍.下面笔者就“观看”和“观测”的区别作了一些讨论.目的在于希望教师讲解狭义相对论的过程中,能够正确、清晰地表述这两个概念,使学生更深刻地理解相应的物理思想.一、“观看”与“观测”的含义“观看”指的是异地测量.“观看”时,观看者和测量对象之间有一定的距离,测量信息需要通过光的传播才能到达测量者,从而实现测量目的.“观测”指的是就地直接测量.就地直接测量时,所用的时钟处在测量现场,观察者也在测量现场,因此测量结果不需要用光作为信号传递到测量者,或者说测量结果被测
In the course of the new round of curriculum reform, students in high school are confused with the concepts of “observation” and “watching” because of their initial involvement in the special theory of relativity. Even in some textbooks written according to the new curriculum standards Confusing these two concepts, leaving high school teachers and students with an obstacle to the understanding of “observation” and “watching.” The following discussion of the differences between “watching” and “watching” The purpose is to hope that teachers can explain the two concepts correctly and clearly in the process of explaining special relativity so as to make students understand the corresponding physical thoughts more profoundly.The first one is the meaning of “observation” and “observation” “Watch” refers to the remote measurement. “Watch”, there is a certain distance between the viewer and the measurement object, the measurement information needs to be transmitted by the light to reach the measurer, so as to achieve the purpose of measurement. “Observation ”Refers to the direct on-site measurement.On-site direct measurement, the clock used in the measurement site, the observer is also measuring the scene, so the measurement results do not need to use light as a signal transmitted to the measurer, or measured results measured
