Research on the Countermeasures of the Development of New Form Stereoscopic Teaching Materials under the 1+X certificate System: ——Taking "CNC milling of parts" as an example

Under the impact of the wave of educational informatization, the new form of stereoscopic teaching materials is the inevitable trend of the development of vocational education teaching materials and an important starting point for mplementing the 1+X certificate system for the cultivation of high-quality applied talents. The central dilemma of the current 1+X certificate system lies in the lack of effective integration between academic certificates and vocational skill level certificates. The reconstruction of vocational teaching materials is an important carrier to realize the integration of "1" and "X". How to discover the organic integration of the curriculum teaching materials corresponding to "1" and the textual research teaching materials corresponding to "X" is the critical problem in the development of new form integrated teaching materials. This paper will take the teaching material of CNC milling of parts as an example, and put forward corresponding countermeasures for the development of new form stereoscopic teaching materials from the four aspects of teaching material positioning, content, layout and evaluation, to further highlight the cultivation role of emotion, attitude and values of teaching materials.
