The so-called discovery of learning, refers to the use of teaching materials or teachers to provide their own independent thinking, self-discovery of knowledge, master the principles and laws. Taking teaching “scale” as an example, how to design effective inquiry activities so that students can take the initiative to construct the concept of “scale” through the process of mathematic generation and development?
