化学实验是化学科学的基础 ,也是化学教学的基础。因此 ,作为化学教师 ,应千方百计地做好演示实验和学生实验 ,鼓励并指导学生做一些选做实验和家庭化学小实验 ,适当布置专题调研性课题。同时要善于开动脑筋 ,勇于创新 ,根据教学需要和具体情况 ,大胆进行化学实验改革 ,充分利? Chemical experiments are the foundation of chemical science and the foundation of chemistry teaching. Therefore, as a chemistry teacher, we should do everything possible to do demonstration experiments and student experiments, encourage and guide students to do some experiments and home chemistry experiments, and properly arrange topics for research. At the same time, we must be good at using our brains and be bold in making innovations. Based on the teaching needs and specific conditions, we must boldly carry out chemical experiment reforms.
