Abstract

Abstract:

Based on the measurements of polymer molecular weight by viscosity method in physical chemistry laboratory, the teaching design and practice based on flipped classroom is introduced. The design process includes analysis of students, teaching materials, laboratory teaching goals, preparing micro lessons and organizing the class and teaching evaluation. Finally, this teaching mode is comprehensively evaluated based on the practice and statistical hypothesis testing.

Key words: Physical chemistry laboratory, Flipped classroom, Teaching design, Teaching mode
