In the "Internet+" era, to understand the difference between the traditional classroom and smart classroom, this study uses the current domestic and foreign classroom teaching behavior research methods as a starting point and analyzes the teaching behaviors in classrooms from six dimensions: resource sharing, teacher lecturing, teacher-student interaction, group cooperation, autonomous learning, and evaluation feedback. A data analysis method is used to conduct a complete statistical study on the teaching behaviors of the 40 lessons selected in the first smart classroom innovation teaching competition in Jiangsu Province, and the analysis results show that there are significant differences in teacher-student interaction, group cooperation, autonomous learning, and evaluation feedback in the smart classroom and the traditional classroom. There is no significant difference in data analysis between resource sharing and teacher teaching, but through further video observation and analysis, the two still show the difference in the actual classroom.
