Interactive teaching is a teaching method of two-way communication between teachers and students, that is, teaching activities are regarded as sincere and harmonious communication between teachers and students, and the teaching process is regarded as a dynamic and developing process of teaching and learning. Students are the masters of mathematics learning, and teachers are the organizers, guides and collaborators of mathematics learning. "Everything is for the development of every student", the important principle of the new mathematics curriculum is "student-oriented", and the ultimate goal is to promote the all-round development of students. "Interaction" is an important method or means to achieve this goal. In the interactive learning between teachers and students, we should:

First, democracy and equality are the premise of interaction.

In traditional teaching, in the teaching activities of "one-word-for-one" and "full-hall irrigation", only the teacher speaks and the students answer, which seriously restricts the students' thoughts and thinking. Only by creating a democratic, equal and harmonious relationship between teachers and students, completely abandoning the "dignity of teaching as a teacher" and fully respecting every student. Only in a democratic, equal, harmonious and relaxed environment can students dare to speak and do, and the spark of thinking can come out in generate. "Please speak your mind boldly", "Who wants to speak" and "Who will cooperate with the teacher" are often used in class. Only when teachers put down their airs and make friends with students will students actively participate in the classroom and be more willing to show their ideas.

Second, creating scenes is the guarantee of interaction.

In the classroom, only by narrowing the psychological distance of students and the distance between students and texts can situations be created. Students learn in the situation created by the teacher, and they have an immersive experience and quickly integrate into their study life. Boring knowledge suddenly becomes rich and interesting, and students' thirst for knowledge can also be successfully stimulated, changing "I want to learn" into "I want to learn", cultivating students' good learning quality and thinking emotion, and improving learning efficiency.

Thirdly, incentive evaluation is the driving force of interaction.

It goes without saying that students, even our teachers, also want to be encouraged and praised by others. Therefore, in teaching, teachers should be good at using inspiring language to transform their love for students into a gentle look, a knowing smile, a warm word, a gesture of approval, and a considerate action, so that students can feel the teacher's concern and appreciation, and psychologically produce an unspeakable sense of pleasure and satisfaction, which will undoubtedly promote them to be positive, thus stimulating their thirst for knowledge, increasing their courage, and raising their awareness.

Fourth, interaction needs role transformation.

Traditional teaching "a mouth, a piece of chalk;" It will be over in 35 minutes, and finally I have some time to do my homework. "The teacher is singing the leading role with relish, but the students in the audience are bored. The new curriculum standard points out that students are the masters of learning, and teachers are only the guides, organizers and collaborators of students' learning. Only by returning the time to the students and giving the podium to the students can the students truly become the masters of learning and return the right to discuss to the students, and the classroom will be full of vitality. In class, teachers can invite students to be "little teachers" in time, so that students can be full of energy when learning knowledge. After the whole class, the students finished their learning tasks happily. Students not only learn fast, but also remember it well, which has achieved good results.
