化学是研究物质组成及其化学变化的科学;它作为一门实验科学,有其自身发展规律,中学教材因受学生年龄、知识水平限制,有些化学概念在中学化学教材中往往是局部的、不完整的。教师在处理中学教材上,课堂授课用语上要注意分寸、留有余地,不要把话说死,防止中学生在化学学习中凭藉想象生搬硬套。
Chemistry is the science that studies the composition of matter and its chemical changes; it has its own development law as an experimental science. Secondary school textbooks are limited by students’ age and knowledge level. Some chemical concepts are often local in the middle school chemistry textbooks. complete. Teachers should pay attention to the teaching of the teaching materials in the middle school, and should pay attention to the teaching of the classroom teaching, and should not leave their words to death to prevent secondary students from using the imagination in the chemistry study.
