Abstract: Schematic interactive visualization design theory is a cognitive teaching theory formed in college teaching innovative exploration, focusing on how to break through the innovation difficulties in teaching and improve the disciplinary thinking ability of teachers and students, using the model method, qualitative research method, case analysis method, induction method and deduction method to analyze the prototype characteristics of its design model. The study found that from the perspective of disciplines bottleneck, teaching schematic interactions, key interations events and learning evaluation, five graphical patterns of integrated teaching, learning, science and industry are established, namely, discipline bottleneck breakthrough model design, teaching schematic interactions visualization design, thematic concept map design, disciplinary thinking extraction key interations event model design, and high-level ability evaluation model design. The design system improves the critical thinking ability of teachers and students and promote the transformation of digital teaching. The practical application of the design system in obstetrics teaching elaborated the specific operation procedure, teaching value and teaching practice effect of diagrammatic formulation, providing examples for the application of this theory.

Key words: discipline bottleneck, teaching schematic interactions visualization, thematic concept map, key interations events, high level ability evaluation of discipline, obstetrics teaching
