演示实验是初中化学教学中较为直观的实验方式。在化学教学中开展演示实验可以帮助学生直观地认识化学反应的现象与规律,从而获得化学知识。因此,在教学过程中教师应当重视演示实验的有效性。利用实验的探究过程及结果,最大程度优化化学教学,以培养学生的实践能力与创新思维。一、遵循以生为本原则,激发学生参与实验学生是学习的主体,教师在教学中要综合考虑学生的学习和发展情况,摒弃一成不变的教学模式,在教学任务的基 Demonstration experiment is a more intuitive experimental method in junior high school chemistry teaching. Performing demonstration experiments in chemistry teaching can help students to intuitively understand the phenomena and laws of chemical reactions and thus acquire the knowledge of chemistry. Therefore, during the teaching process, teachers should pay attention to the effectiveness of demonstration experiments. The use of experimental exploration process and the results, the maximum optimization of chemistry teaching to cultivate students’ practical ability and innovative thinking. First, follow the principle of taking students as a foundation, to stimulate students to participate in experimental students is the main body of learning, teachers in teaching should take into account the learning and development of students, to abandon the static teaching mode, based on teaching tasks
