Reinforce perception
In concept teaching, rich and varied perceptual materials should be provided to guide students to observe and operate, so as to deepen their perception of things. In this way, they can better prepare for the formation of concepts.
Pay attention to appearance
By guiding students to recall and compare different examples, it can help them to establish a clear representation, so as to better understand the essential attributes of things.
Reveal essential attributes
Once students form a clear representation, we can guide them to analyze, compare and synthesize, and reveal the essential attributes of things. Then, we extend these essential attributes to all similar things to help them form correct concepts.
Similarity of mammals
Taking "mammals" as an example, students can observe the appearance, reproduction and feeding of cats, cows, monkeys and lions, and then guide them to find out the similarities and differences between these animals. Finally, it can be concluded that "cats, cows, monkeys and lions have many similarities in appearance, reproduction and rearing offspring, and all belong to the category of mammals."
