针对中学化学实验中存在的浪费水及环境污染的问题,在中学化学实验中开展“节水减排”教育意义重大。其创新方法主要是针对不足,开展创新课题探究;找到教育学生践行节水、排污的好方法,课后开展废液综合利用的课题探究及实践;开展宣传与展示等。在创新实践方面,主要从节水、防污创新课题探究及实践,宣传推广三个方面开展教学。 In view of the problem of waste water and environmental pollution in chemistry experiments in middle schools, it is of great significance to carry out “water saving and emission reduction” education in chemistry experiment in middle schools. The innovative methods are mainly for lack of exploration of innovative topics; to find a good way to educate students to practice water-saving, sewage, waste water after class to carry out the project of comprehensive utilization of exploration and practice; to carry out publicity and display. In terms of innovation and practice, teaching mainly focuses on three aspects: water saving and pollution prevention research, practice and promotion.
