Abstract:

As a required course for the environmental engineering major, environmental chemistry has overlapped teaching content with the four major basic chemistry courses (inorganic chemistry, organic chemistry, physical chemistry and analytical chemistry). In order to improve classroom teaching efficiency and students' learning enthusiasm, our teaching team summarizes and analyzes the similar knowledge between environmental chemistry and the four basic chemistry courses, and then updates and optimizes the teaching content. Meanwhile, with assorted teaching methods including questioning, comparing and discussion, we guide students to explore "new knowledge" from "known knowledge" to deepen knowledge layer by layer. Furthermore, the "rain classroom" teaching mode is applied to help the teaching connection, which can improve the teaching effect.

Key words: Environmental chemistry, Basic chemistry, Repeated content, Teaching connection, Teaching reform
