1 忌超纲 中学教学大纲是国家对某一门学科教学的统一要求,是编写教科书和教师进行教学的直接依据,是衡量教学质量的重要标准。所以,考试的内容在深度、广度上,都不应与现行教学大纲相抵触,不然教学活动将会无所适从。曾见到某杂志上刊载了这么一道初中物理试题:“已知录音机放音时,磁带的主动轮转速恒为n_0在主动轮上所绕磁带的半径分别是1.1厘米、1.9厘米和2.4厘米时,从动轮上所绕磁带的半径分别是2.4厘米、1.9厘米和1.1厘米。在这三种情况下,从动轮的转速应该分别等于_____、_____和_____”。这道题在联系实际方面不错,但属于高一物理的内容,不能作为初中物理的考题。有些知识属于“常识性了解”,按照九年制义务教育初中物理教学大纲,是只教不考的部分,也不能出现在试卷之中。
1 Avoidance of Superclasses The secondary school syllabus is a unified requirement for the teaching of a certain discipline in the country. It is a direct basis for the preparation of textbooks and teachers for teaching, and is an important criterion for measuring teaching quality. Therefore, the depth and breadth of the examination should not be in conflict with the current syllabus, otherwise the teaching activities will be at a loss. I have seen a magazine issue such a junior high school physics test: “When the known recorder is playing, the driving wheel speed of the tape is always n_0. The radius of the tape wound on the driving wheel is 1.1 cm, 1.9 cm and 2.4 cm, respectively. The radius of the tape wound on the driven wheel is 2.4 cm, 1.9 cm and 1.1 cm, respectively. In these three cases, the rotational speed of the driven wheel should be equal to _____, _____ and _____, respectively. This question is good in connection with the actual situation, but it is a high-level physics content and cannot be used as a test for junior high school physics. Some knowledge is “common-sense understanding”. According to the ninth-grade compulsory education physics teaching syllabus, it is only a part of teaching and examination, and it cannot be included in the examination paper.
