doi:10.3866/PKU.DXHX202206048

Abstract

Abstract:

Under the background of new agricultural science education and considering the shortcomings of basic chemistry courses in agricultural colleges and universities, reformation, innovation, and practical activities were implemented through the design of course teaching content, development of teaching resources, mining of ideological and political elements of the course, updating of teaching methods and models, and establishment of evaluation index system. This study is expected to lay the foundation for further improving the impact of teaching and students' comprehensive ability as well as for cultivating new talents in agriculture and forestry.

Key words: New agricultural science, Agricultural colleges and universities, Basic chemistry course, Teaching practice
