doi:10.3866/PKU.DXHX202107021

Abstract

Abstract:

Under the concept of blended learning, how to optimize the teaching design of analytical chemistry course and improve the effectiveness of teaching has become a subject that needs to be solved urgently. According to the characteristics of blended teaching, we take efforts to integrate high-quality digital curriculum resources, reconstruct teaching content, adopt diversified assessment indicators, and gradually enhance the connotation of curriculum. By focusing on students as the main body, interactive learning-oriented, emphasizing the construction process of knowledge, the implementations can enhance students' independent learning ability and comprehensive literacy, and ultimately achieve the teaching purpose of cultivating innovative talents.

Key words: Analytical chemistry, Blended teaching, Teaching design, Teaching reconstruction
