What is a unit? Next, we will generally say that we want to lengthen the content of our design, such as a chapter, such as a module, such as a face in a module, such as compulsory two, and we can design it into a complete content. Of course, you can also do cross-chapter teaching design. For example, analytic geometry is divided into two parts, one part is compulsory, analytic geometry is preliminary, and the other part is based on the cone main line, which is also included in elective one and elective two. Analytic geometry in senior high school is a whole. It is very important for us to have an overall thinking on how to design these teaching methods.

On the third level, we also hope that teachers can attach importance to the unit teaching design about what we usually call methods and abilities. For example, one of our teachers' concerns is computing, so we can consider how to design a compulsory module as computing ability. Let our students have a significant improvement from junior high school level. We can analyze which carriers support computing power in compulsory courses. Then we say, in these carriers, how should we help students improve their computing ability? Therefore, I think these ideas are very important in the design of unit teaching. Compared with the teaching design of our traditional unit, I hope to broaden my horizons. In the unit teaching design, there are one or two core keywords, the first is the whole,

We grasp how to do a good job in unit teaching design from the whole curriculum. I think this is a key word, and the second key word is efficiency.

I think doing a good job in unit teaching design will let you know when and to what extent I will talk about it, and I will make some specifications on this matter later. Of course, the scope of thinking about unit teaching design is still relatively large. For example, for some concepts, such as radian, we can also think of it as a unit. Because now is definitely not the time to talk about the definition of radian, it will involve radian. This will not explain clearly to students why the concept of radian should be added, so this time I hope to help teachers broaden their horizons and think about our overall teaching from a holistic perspective. This will improve teaching efficiency. I think I'll make such a simple explanation.
