“以实验为基础”是化学学科的基本特征。初中化学课程中的化学实验,虽然绝大多数是对物质组成、结构、性能及其变化规律的再认识,但从本质上看,这一过程与科学家进行的科学研究中的化学实验是一致的:它一方面可以直观、生动、形象地产生化学问题,能对学生在科学探究中提出的猜想或假没进行验证;另一方面学生通过实验
“Based on experimentation” is a basic feature of chemistry. Although most of the chemical experiments in the chemistry curriculum for junior middle school are based on the understanding of the composition, structure, properties, and laws of change, in essence, this process is consistent with the chemical experiments conducted by scientists in scientific research. : On the one hand, it can produce chemical problems intuitively, vividly, and vividly. It can verify students’ guesses or falsity in scientific inquiry; on the other hand, students pass experiments.
