实验是化学的灵魂和魅力。作为启蒙的初中化学,课堂演示实验是化学教师使用最常见的一种实验教学形式。教师既要对实验熟记于心,又要在实验时辅以规范的操作和精准的语言描述,让学生在一种讨论的氛围中接受新知识,使学生感受化学实验之美,提高学生学习化学的积极性。在化学教学实践过程中,自己对化学课堂演示实验的理解在不断地更新和完善。下面就用文字把这些演变过程记录下来。一、初为人师,实验只为完整展现 Experiment is the soul and charm of chemistry. As an enlightenment junior high school chemistry, classroom demonstration experiment is the most common form of experimental teaching used by chemistry teachers. Teachers should not only remember the experiment well, but also in the experiment supplemented by standardized operation and accurate language description, so that students in a discussion of the atmosphere to accept new knowledge so that students feel the beauty of chemical experiments to enhance student learning chemistry The enthusiasm. In the process of chemistry teaching practice, my understanding of chemistry classroom demonstration experiment is continuously updated and improved. Here’s the text to record these evolutions. First, as a teacher, the experiment is only a complete show
