Abstract

Abstract:

Blended learning refers to the combination of traditional classroom teaching with online preview provided by SPOC. Due to the policy in college entrance examination, some students have not learned Chemistry Elective 3-Structures and Properties of Matter in their senior middle school. Most of the engineering major students have difficulties in studying the section of Structure of Mater in the courses of Fundamentals of Modern Chemistry. To bridge the gap, light version of blended learning has been applied since 2015. Students could preview the online SPOC differently depending on their foundation and needs, in the section of Structure of Matter, and report their learning difficulties. At the same time, mobile interactive software and seminars in small classes have been introduced to the in-class activities. The performance of the final exam has been improved. These results contribute to the construction of progressive and blended learning systems in the future teaching.

Key words: Blended learning, SPOC, Learning foundation differences, Structure of mater
