化学是在原子、分子基础上研究物质组成、性质、结构及变化规律的一门科学。世界都是由物质组成的,化学让人们从不同的视角了解世界。义务教育之所以开设初中化学这门课程,是因为初中的学生告别了儿时的幼稚,他们的思想逐步走向了成熟,正处于一个智力发育的最佳时期。这个时期是学习化学最好的阶段。但是如何让学生学好化学,一直是初中化学老师关注研究的问题,根据教学经验,发表观点,为初中生更好地学习化学知识作出一些贡献。
Chemistry is a science that studies the composition, nature, structure and variation of matter on the basis of atoms and molecules. The world is made of matter, and chemistry lets people understand the world from different perspectives. The reason why compulsory education is to set up junior high school chemistry curriculum is because junior high school students bid farewell to their childish childhood, and their thinking has gradually matured and is in the best period of intellectual development. This period is the best stage to learn chemistry. However, how to make students learn chemistry well has always been a concern for junior high school chemistry teachers. Based on their teaching experience, they expressed their opinions and made some contributions to junior high school students in better learning chemical knowledge.
