Due to the combination of sensibility and rationality, the connection of art and technology, it is difficult to measure the conception, deepening process and design results of architectural courses. This also makes design course teaching generally have no rules to follow and cannot be followed, and it is difficult to use standard methods and step-by-step procedures to explain and impart professional knowledge. The teaching effect fluctuates greatly. The spatial operation method realizes the methodological training of step by step control and layer by layer depth, taking this as the starting point to guide the students to form the learning method of adapting to the task goal and restricting elements, further constructing a self-contained and logically mature design vocabulary, and cultivating students to form a perfect architectural professional accomplishment from the shallow to the deep and from the simple to the complex.
