From intuitionistic representation to intuitionistic construction: the strategy of cultivating the ability of geometry visualization based on the teaching of “sketch drawing”

Geometric intuition refers mainly to the awareness and habit of using diagrams to describe and analyze problems. In order to realize the transfer of the visual representation to visual construction, the visualization strategy of geometric visual ability based on the teaching of "Sketch drawing" is put forward Through the experiencing of "sketch Drawing", intuitive consciousness will be built; with the abstraction of "sketch drawing", intuitive cognition can be developed; and with the internalization of the steps of sketch drawing, the intuitive quality accumulates.
