初中物理教学中,“内能”“热量”“温度”的概念极易与日常生活所说的“热”混淆,导致对“热量”认识出现错误。因此,在教学中,防止和纠正这样的错误就是一个需要注意的问题。讨论热量的多少与哪些因素有关,可以通过后续课程教学,通过实验探究逐步讨论和研究。正如初中物理未给电压下定义却仍进行欧姆定律的教学,直至高中才能给出定义一样,内能概念的建立,也要通过初中到高中的完整过程完成。
In junior high school physics teaching, the concept of “inner energy ” “calorie ” “temperature ” can easily be confused with “hotness” in everyday life, resulting in mistakes in understanding of “calorie ”. Therefore, in teaching, to prevent and correct such a mistake is a problem that needs attention. Discuss the amount of heat and what are the factors that can be through the follow-up teaching, through the experimental exploration of progressive discussion and research. Just as the physics of junior high school did not define the voltage, it still conducts Ohm’s teaching until the definition of internal energy is given. The concept of internal energy is also completed through the complete process of junior high school and high school.
