化学是一门以实验为基础,研究物质的组成、结构和性质的学科。在教学实践中,化学实验也是探索性的研究活动之一。化学实验是培养学生创新能力和优良素质的有力手段,是教师引领学生对课本知识进行验证的教学活动。教师在实验准备、新知讲解、实验过程介绍、注意事项举例和实验原理分析等化学实验环节,要从整体上把握实验,以使实验收到良好效果。微型实验在化学教学中的应用,不仅可以节约经费、减少污染、降低危险,更重要的是可以增加学生
Chemistry is a discipline that studies the composition, structure, and nature of matter on an experimental basis. In teaching practice, chemical experiments are also one of the exploratory research activities. Chemistry experiment is a powerful means of cultivating students’ innovative ability and excellent quality, and is a teaching activity that teachers lead students to verify textbook knowledge. Teachers in the experimental preparation, the new knowledge to explain, the introduction of the experimental process, precautions and experimental principle analysis and other chemical experiments, we should grasp the experiment as a whole, so that the experiment received good results. The application of micro-experiment in chemistry teaching can not only save money, reduce pollution and reduce the risk, but more importantly, can increase students
