Students' learning mathematics is a purposeful and conscious behavior, which requires an intrinsic motivation to achieve their learning goals. This purpose is the students' strong desire to learn mathematics. Only when students have this desire to learn can they actively participate in the whole learning process. Therefore, in the teaching process, we teachers should use various forms to stimulate students' interest in learning and arouse their enthusiasm for active participation, thus improving the efficiency of classroom teaching.
1, create a situation to stimulate interest
In teaching, interesting learning materials can arouse students' enthusiasm in learning mathematics. For example, after teaching "solving application problems with formulaic equations", I designed a situational exercise of "saving lambs". Just when the wolf wanted to eat the lamb, the mountain king tiger came. In order to show his "justice", the tiger stipulated: "If the lamb makes a mistake, the wolf can move forward. If it does it right, the wolf will take a step back and stay away from the lamb. " In such an interesting fairy tale situation, students' instinctive "sense of justice" was immediately aroused, their enthusiasm for learning was high, and they were extremely serious in doing problems. Under the correct practice of students again and again, the wolf was forced to retreat step by step. When the wolf retreated to the "river" and forcibly rushed into the river, the students' desire to "punish evil and promote good" was finally satisfied, and the whole class could not help cheering loudly. The classroom atmosphere reached a climax, which greatly improved the classroom efficiency.
2, hands-on operation, stimulate interest
Because mathematics knowledge itself is abstract and boring, it contradicts the characteristics of students' lively thinking and concrete image. In order to reflect students' curious and active characteristics, strengthen students' cognition and understanding of various knowledge points, organically combine students' thinking and ability, and more importantly, let students participate in practice, stimulate their interest and make them eager to try. For example, in the process of teaching the derivation of parallelogram area formula, students actively explore, observe, discuss, discover and communicate by cutting, moving and spelling, and boldly derive the parallelogram area calculation formula. When the students converted the parallelogram into a rectangle by cutting and mending, they asked: What is the connection between the rectangle after cutting and mending and the original parallelogram? According to the above findings, can the calculation formula of parallelogram area be derived? After the operation, the students made clear the internal relationship between the two figures and established the spatial forms of rectangle and parallelogram, which made them have a lot to say and they were interested in participating. It is completely possible to process and sort out the formula, and classroom teaching is more effective.
Second, select classroom exercises to improve classroom efficiency.
Practice has proved that too much blind practice is unscientific. Not only can not stimulate students' positive thinking activities, but because of a large number of mechanical exercises, students' thinking will become dull, and with so much homework, their free time and rest time will be squeezed out, which will hinder the normal development of their thinking and make them in a passive state in their study. Therefore, in teaching, teachers should carefully select exercise questions according to the teaching objectives and requirements, combined with the actual situation of students, so that students can practice in a planned way, strive to be precise but few, practice on ideas, help students learn actively and improve classroom efficiency.
A class lasts only 40 minutes, and it passes in a blink of an eye. Therefore, every minute in class can't be wasted. It should be used as much as possible in teaching content, and these 40 minutes must be used on the cutting edge.
