So far, pedagogy has not formed its own unique visual angle and thinking mode to understand humans and the world in general; consequently, it is always counting upon other subjects, which is the root of the crisis in pedagogy. Focusing on the "visual angle" and "thinking mode", this article puts forward a new proposition "pedagogic understanding" to make a concrete analysis of a basic hypothesis, some basic problems and some research ways. The purpose is to form pedagogy's own way of understanding on the foundation of delimitation and integration with other subjects.
