Abstract

Abstract:

Flipped classroom as a kind of teaching method advocating active learning, has been widely welcomed as an online-offline hybrid learning method. Flipped classroom mainly includes two sections including students' Online autonomous learning away from the classroom and interactive learning activities in classroom based on encouraging problem-solving and experiential learning. In this paper, flipped classroom teaching method and traditional teaching method were used to carry out inorganic and analytical chemistry course for freshmen majored in biology. Additionally, SPSS was used to analyze students' performance and satisfaction with flipped classroom teaching method. The results show that students are actively participated in the flipped classroom teaching, the overall performance has been significantly improved, and students' satisfaction with the flipped classroom teaching method is higher. Thus, the flipped classroom teaching method has certain advantages over the traditional teaching method.

Key words: Biological majors, Flipped classroom, Inorganic and analytical chemistry, SPSS analysis
