The determination of teaching objectives is the basis for the smooth development of practical comprehensive application courses, and it is also the starting point and destination of the whole teaching activities. Undoubtedly, the understanding of practice and comprehensive application process is the basis and necessary prerequisite for the orientation of oral labeling teaching.
Practice and comprehensive application, as a field, place great emphasis on connection and synthesis, but when it comes to a class or a special topic, in what scope should it be "connected" and to what extent should it be "integrated"? There's plenty of room here. However, no matter what field, subject and method the activity involves, the teaching objectives should be specific and clear in order to make the activity effective. In addition to giving students a good emotional experience and feeling the role of mathematics in daily life, they should also find a foothold in their activities and consider what kind of mathematics knowledge to rely on to maintain their proper "mathematics taste".
