比热容的探究一直是初中的难点,教材(人教版实验教科书)中提供的实验操作较为繁琐且误差较大,往往导致概念难以建立,建立后的概念又由于内涵较深、外延较广,涉及热量、温度变化、质量三重概念间的关系,学生又难以理解.笔者认为,若能大胆重组教材结构,改进探究实验,建构“身边的
The research on specific heat capacity has always been a difficulty in junior high schools. The experimental operations provided in the textbook (PEP Experimental Textbook) are cumbersome and have a relatively large error, which often leads to the difficulty of establishing the concept. The concept after the establishment is due to the deeper connotation and wider extension. The relationship between heat, temperature change, and quality triple concepts is difficult for students to understand. The author believes that if we can boldly restructure textbooks, improve inquiry experiments, and construct “around
