在元素化合物性质的传统教学中,通常第一节课教师讲授物质性质及相关实验,后续进行实验验证和讲解练习。使用“翻转课堂”的教学方式,引导学生课前预习物质的性质,组织学生课上根据物质性质的差异设计鉴别实验并动手实践,最后归纳鉴别实验原理,找出物质间相互转化的方法,从而建构物质性质的知识体系。整节课容量相当于传统教学的2~3课时。
In the traditional teaching of the properties of elementary compounds, the teachers of the first class usually teach the nature of matter and related experiments, followed by experimental verification and explanation exercises. Use “flip classroom” teaching methods to guide students to preview the nature of the material before class, organize students to classify the experiment based on differences in the nature of the material and hands-on practice, and finally summarize the principle of identification experiments to identify the method of mutual transformation between substances , So as to construct the material system of knowledge. The whole class capacity equivalent to 2 to 3 hours of traditional teaching hours.
