Abstract:
Based on the knowledge characteristics of the chapter on nitrogen group elements, and combined with the teaching experience of our excellent video open course, this paper has probed the teaching reform of inorganic elements chemistry from the following aspects:using the principle of chemistry to explain the structure and properties of substances, designing problems to guide students to think and cultivate their learning ability, instructing students to be good at inducing the changing laws of material properties, paying attention to the relationship between the elements and compounds and practices of production and life. It aims to guide students to learn, memorize and master the knowledge of element chemistry effectively, and improve the quality of classroom teaching.
