Taking the junior professional course of architecture--the preliminary course of architectural design as an example, this paper analyzes the problems existing in the current professional courses of lower grades, puts forward the opinion that the cultivation of innovation & practice ability should be included in the professional training objectives, and the corresponding reforms of the training program and teaching methods should be made, in order to provide the reference for the construction in the basic teaching of architecture.
