一、变演示实验为学生实验化学教学演示实验和学生分组实验是实验教学的两大块,笔者认为无论是演示实验,还是分组实验,应充分调动学生的理性思维,不能仅将实验作为呈现现象的工具,更多地应该借助于实验启迪学生的化学思维,逐步揭示化学现象背后所蕴含的科学本质。 First, the variable demonstration experiment Students experimental chemistry teaching demonstration experiments and student group experiments are two major pieces of experimental teaching, I believe that both demonstration experiments, or group experiments should be fully mobilized students’ rational thinking, not only the experiment as a rendering of the phenomenon More tools should be enlightened by means of experiments to enlighten students’ chemistry thinking and gradually reveal the scientific essence behind the phenomena of chemistry.
