一、中学化学实验教学自成系统以实验为基础的化学学科特征,决定了化学实验教学系统是化学教育系统中的主要子系统,应有其能决定性地影响化学教育质量的教育目标和教学结构.中学化学实验的教育目标,在认知领域中可概括为探索和形成、使用和评价化学理论与技术知识;在操作领域中可概括为掌握实验基本操作技能和化学技术基础;在情感领域中可概括为形成科学观点,提高心理素质.中学化学实验的教育目标决定了它的教学结构.教学结构的特征,
First, the self-contained system of chemical experiment teaching in middle schools is based on the chemical characteristics of experiments, which determines that the chemical experiment teaching system is the main subsystem in the chemical education system, and it should have educational goals and teaching structures that can decisively influence the quality of chemical education. The educational goals of middle school chemistry experiments can be summarized in the cognitive field as the exploration and formation, use, and evaluation of chemical theory and technical knowledge. In the field of operations, it can be summarized as mastering basic experimental operating skills and chemical technology foundations; in the field of emotions. It can be summarized as forming a scientific viewpoint and improving psychological quality. The educational goal of middle school chemistry experiment determines its teaching structure, characteristics of teaching structure,
