Research on the Training Strategy of "Little Teacher" in Primary School Mathematics Teaching: The Training Method of "Little Teacher" in Primary School Mathematics Teaching Knowledge Tongliang Second Experimental Primary School I. What is a "Little Teacher" Mr. Tao Xingzhi said: "Life is life. Those who lived that life first were the teachers who lived that life, and those who lived that life later were the descendants who lived that life. Students are people who have studied life, and teachers' duty is to teach people life. The child has lived this life first, and he is willing to teach his predecessors and peers to live the same life. He is a veritable little teacher. " From his words, we can easily understand that students can also be teachers, and every student can participate in the exchange of knowledge and information. "Small teacher system" is a significant development of Tao Xingzhi's universal education method. The author believes that the connotation of the "little teacher system" that we have implemented today has been further expanded and developed. This new type of "small teacher system" is to carry forward people's subjective spirit, let students take the initiative to assume roles in teaching activities, and develop their abilities in activities, thus forming an educational atmosphere of mutual influence and promotion.
