Abstract

Abstract:

At present, with the development of China's internet and information technology, the multimedia teaching has been paid more attention. It's the critical step that how to combine effectively the traditional classroom teaching with online teaching in the new situation to improve the university teaching quality. This paper explores and reforms the current teaching model of analytical chemistry, and builds an online + offline blended teaching mode that includes four sections: preparation, preview, teaching and teaching reflection. Furthermore, this paper proposes a comprehensive evaluation system throughout the entire teaching process, and finally puts forward some suggestions for the problems of the blended teaching mode.

Key words: Analytical chemistry, Classroom teaching, Online teaching, Blended Teaching mode, Comprehensive evaluation system
