The work aims to sort out and study the optimization scheme for digital design and manufacturing of teaching organization based on the theory of practical community of cognitive science. The key points and methods for design of teaching organization were explored from group, heterogeneity and practicality which are the basic elements and characteristics of the theory of practical community. The teaching organization under the theory of practical community was an effective way to achieve the goal of training applied creative design talents. The theory of practical community provides eeffective paths and measures for optimizing teaching organization at the practical application level, such as focusing on the transformation of teaching paradigm, constructing a learning community, promoting students' participation in the process, and diversifying the assessment on study achievement. At the same time, theoretical research is effectively applied to the teaching practice design of NUA. The design and construction of digital medical rehabilitation products is an applied subject in which art and technology are highly intersected. The teaching practice will be carried out in the form of workshops in the following three aspects:adding practical tasks to the curriculum, promoting collaboration in teaching organizations, and implementing the learning process through feedback mechanisms.
