化学是一门以实验为基础的科学。实验是科学课的主体,观察和实验是科学课的灵魂,是激发学生学习兴趣和增强创新能力的重要途径。教师规范化地做好演示实验,是学生学习化学实验基本技能的基础。通过列举具体案例,分析了教师在实验演示中要规范化传授的基本技能要点,同时深入挖掘实验背后所承载的科学方法与科学思维的培养。
Chemistry is an experiment-based science. Experiment is the main body of science class, observation and experiment are the soul of science class, which is an important way to stimulate students’ interest in learning and enhance their ability to innovate. Teachers to do a good job of standardized demonstration experiment, is the basis for students to learn the basic skills of chemical experiments. By enumerating specific cases, the paper analyzes the basic skills that teachers should standardize and impart in the experimental demonstration, and at the same time digs out the scientific method and scientific thinking carried by the experiment.
