Abstract: As the basic classroom teaching and learning behavior, "mimics"has ontological meaning, involving body, performance, imagination, inner image. In this sense, mimics is not negative "imitation", but self-expression based on scene layout and performance, which reflects and constructs teaching and learning rules in classroom. This paper focuses on the core research question-what instruction logic does the mimics sequences contain and construct? This paper, using the documentary method, takes sequence as analysis carrier, analyzes the interaction habitus created by mimics.Video analysis based on the documentary method not only combines situation, body and practice, but combines the comprehensive concerns of noumenon and situation, universality and diversity, transient and diachronic dimension,through which educational practice and theoretical research methodology can be updated.

Key words: mimics, videoanalysis, documentary method, methodology
