现行高中物理教学中,有关理想气体状态图线的知识介绍得不多,而历年高考试题中出现的概率却较高。由于学生对此知识点认识肤浅,一知半解,导致应试得分率很低。所以,我们要重视理想气体状态图线的教学,在讲清图线中的点、线、斜率物理意义的基础上,要特别强调理想气体状态图象的“三性”(科学性、共融性、互换性)教学,从而保证学生学好和用好图象。
In the current high school physics teaching, knowledge about the ideal gas state diagram is not introduced much, but the probability of appearing in the high exam questions in previous years is higher. Due to the students’ superficial knowledge of this knowledge, the lack of knowledge has led to very low test scores. Therefore, we must pay attention to the teaching of ideal gas state maps. We must emphasize the “triple nature” of the ideal gas state image (scientific and communicative) with a view to clarifying the physical meaning of points, lines, and slopes in the map. Sex, interchangeability) to ensure that students learn and use good images.
