Another aspect of learning: Knowledge shielding

In many cases, we focus too much on the display and delivery of knowledge. When the amount of knowledge exceeds the receiving capacity of Knowledge recipients, the teaching effect can be imagined, I was overwhelmed by many unfamiliar knowledge points in an instant and couldn't grasp the essence of this learning, Just like you tied up 100 ropes and let you go swimming. You took care of the ropes, or swimming?
The same is true for teaching. There is a certain degree of knowledge and ability to receive students. In this case, we need to skip the branches and use a simple black box model to hide complicated details, this gives students a clear learning structure. When the students' reception ability is improved, they can choose to reveal the content in the black box. This is the best teacher.
The same is true for a good book. In addition to granting knowledge, we must also shield the knowledge. In this case, readers may not be overwhelmed by weeds.
