化学是一门以实验为基础的自然学科.在学习化学知识的时候,离不开化学实验.所有的化学实验都是立足于条件的控制.也就是说,在初中人教版化学教材中,对比实验的数量非常多.为了吸引初中生的课堂注意力,教师应当在初中化学教学中引入对比实验,凸显化学实验的精髓,优化课堂教学环节,提高化学教学质量.一、在初中化学教学中突出对比实验的比较思想在初中化学学习阶段,人教版化学教材为学生准备了不同类型的化学实验.这些实验的类型,大 Chemistry is a natural science based on the experiment in the study of chemical knowledge, can not be separated from chemical experiments.All the chemical experiments are based on the conditions of control.In other words, in the junior high school PEP textbook, In order to attract junior high school students’ attention in class, teachers should introduce comparative experiments in junior high school chemistry teaching to highlight the essence of chemical experiments, optimize classroom teaching and improve the quality of chemistry teaching. Highlight the comparative thinking of comparative experiments in junior high school chemistry learning phase, the PEP textbook for students to prepare different types of chemical experiments.The type of experiment, large
