Abstract

Abstract:

This paper introduces the blended teaching practice of flipped classroom based on online course in college chemistry in Tianjin University since 2017, including the organization mode of teaching process, the selection of flipped leaning content, the proportion of flipped learning time in total class hours, the final test scores analysis and teaching reflection. In this study, flipped class hours accounted for 30%-50% of the total class hours and teaching content in which students had already accumulated some basic knowledge during middle school were selected in flipped classroom. The result showed that the teaching effect of flipped classroom was superior to that of traditional parallel class.

Key words: College chemistry, Flipped classroom, Online course, Blended teaching
