First, stimulate interest and pay attention to the word "citation".
As we all know, interest teaching is the key to measure the success or failure of teachers' mathematics teaching in each class. The improvement of students' mathematics scores depends largely on whether students are interested in mathematics, such as triangles, parallelograms and trapeziums in geometric figures. Teachers must, according to the requirements of the unit curriculum standards, let students go deep into daily life on the basis of previewing textbooks, make effective observations, see which objects belong to this geometric figure, and then guide students to make their own learning tools according to reality. Through inspiration and guidance, some children can be a multi-purpose learning tool. Of course, in the classroom operation, we must achieve: clear goals, clear explanations, Qi Xin's cooperation and clever demonstrations, which can not only stimulate children's interest, but also enhance students' understanding and improve the quality of classroom teaching.
Second, carefully doubt and highlight the word "discussion".
Careful questioning is one of the important means to inspire students to think. In classroom teaching, it is the key and difficult for teachers to grasp the doubts in classroom teaching. First of all, teachers are required to make three preparations (one textbook, two students and three curriculum standards) in the course of preparing lessons. For example, when teaching triangle area, let students make their own learning tools and demonstrate teaching AIDS, and cut them into two equal triangles along any diagonal of the parallelogram. Then the teacher immediately asks: What is the relationship between the base and height of the cut triangle and the base and height of the original parallelogram? What is the relationship between the area of triangle and the area of original parallelogram? Finally, while the iron is hot, I doubt again: can we deduce the area formula of triangle from the area formula of parallelogram? In this way, through this series of doubts, teachers not only stimulate students' thirst for knowledge, but also inspire students' logical thinking.
Third, pay attention to feedback and emphasize the word "practice".
Classroom practice is the basic way to develop students' thinking and cultivate their innovative ability, and it is also the concrete practical activity of students' innovative learning. Practice should not only have clear goals and requirements, but also pay attention to various levels and forms of practice. In order to stimulate interest, it is generally stipulated that the practice and homework time of each math class is not less than one-third or fifteen minutes of a class. From basic training, consolidation exercises, key exercises to classroom assignments or variant exercises, flexible use of comprehensive exercises to climb forward. Another example: measuring land, basic training, etc. Let the students practice the exercises in the textbook first, then comment on * * *, and finally realize the area reciprocity; Then supplementary exercises, combined with real life: step by step, step by step. Through teaching practice, we feel that only by optimizing the classroom teaching structure can we stimulate students' interest and thirst for knowledge, which is conducive to developing intelligence and cultivating ability. Finally, the purpose of improving the quality of classroom teaching is achieved.
