Whether the teaching method can match the teaching content and the actual situation of students directly affects the effect and efficiency of classroom teaching. Teaching method is the general name of the methods and means used by teachers and students to achieve the same teaching goals and complete the same teaching tasks in the teaching process, including teachers' teaching methods and students' learning methods. Teaching method is not fixed, it is a dynamic concept, which constantly changes and develops with the changes of teaching activities and the deepening of students' understanding of the teaching process. The author thinks that in the teaching process, different teaching methods should be chosen according to different contents and different students.
Second, promote cooperation and make the classroom harmonious and pleasant.
Cooperative learning creates a suitable environment and conditions for students' all-round development, especially individual socialization development. In teaching practice, it is because of problems or difficulties that cooperative learning becomes more important. Before each new lesson, teachers ask students to preview the contents of this section according to the syllabus, and ask students to record the problems encountered in the preview in the main area of the notebook, solve the problems that can't be solved in class before class, solve the problems that can't be understood in class after class, solve the problems that can't be solved by individuals in groups, and ask teachers for advice on the problems that can't be solved by groups, so as to realize the real "teaching soldiers, training soldiers and Qiang Bing". If there is no problem, go to find it, encourage and guide students to discuss with each other at the same table and near the table, so that students can have enough time to experience the problem-solving process in class, encourage students to examine and discuss the problem independently, and leave the problem analysis to themselves. This practice can avoid students' excessive dependence on teachers, and of course teachers should help them when they encounter difficulties. For example, a group of students deeply feel that traffic jams in cities are serious. In order to investigate this problem, they spent the whole weekend counting the traffic flow on the street. Finally, they wrote the article "Solving the Problem of Urban Road Layout by Mathematical Methods". In this paper, the traffic congestion in different periods of the day is shown by frequency statistics and frequency distribution line diagram, and my own views are expounded by analyzing the scatter diagram of obstacles and vehicles on both sides of the road, and many improvement suggestions are designed by myself. Clear viewpoints and clear thinking make the knowledge in the chapter "Statistics" fully applied. In this process, students can get impressive and unforgettable mathematical results.
Third, create a good atmosphere and expand students' participation.
"Subject participation" should be a natural behavior of students' active consciousness. Without the participation of students, it is impossible to be efficient. "Forcing orders" won't work.
It is necessary to create a relaxed and harmonious classroom atmosphere and interesting problem situations, so that students can unconsciously engage in various activities such as finding problems, asking questions, analyzing problems and solving problems. In such a class, students have a sense of security and are not afraid of "showing off" or "losing face". The true thinking state is convenient for teachers to take countermeasures in time, collect the essence of creative thinking from the bright spots of students' wisdom, sum up experiences and lessons from going astray, and realize a win-win situation for teachers and students.
Mathematics class should be a group talk, and students' main participation should not be a "talent show" of a few "high flyers". Teachers must mobilize students to discuss this topic. Of course, excellent students should eat well so that their thinking and ability can be fully developed. However, the so-called "underachievers" must not give up, and should be tailored according to their tastes, so that they can feel their progress and improvement after solving them. Students' participation in mutual inspiration produces complementary and mutually promoting effects that individuals alone cannot match.
Fourth, feedback information quickly and effectively, and optimize the best fit between teaching and learning in time.
"An effective behavior must obtain information through some kind of feedback process, so as to know whether the purpose is achieved." As the controller of the teaching process, teachers must make the teaching fit the students' learning level properly through classroom information feedback, and let the students' curiosity and thirst for knowledge be stimulated in their own settings, thus showing the best state of teaching and learning.
Fifth, effectively create classroom summary and strengthen the finishing touch of effective classroom.
In the process of high school mathematics classroom teaching, classroom summary is almost essential for every class. Indeed, at the end of a class, it is of great significance to comprehensively summarize the key contents of a class, review the process of learning and exploration, and understand important thinking methods for consolidating classroom teaching achievements, deepening the structure of knowledge network, cultivating students' ability, and summarizing and reflecting on teachers' own teaching.
At the end of class, we put forward some enlightening questions without answering them, so as to create suspense, pave the way for new lessons and make a good connection between old and new lessons. For example, the lesson of "judging the perpendicularity of two planes" in solid geometry at the end of class can be summarized as: "Today we discussed the definition and judgment of the perpendicularity of two planes. According to the previous model of studying the positional relationship between two elements in space, we should study the nature of the perpendicularity of two planes. After class, please study the nature of two planes perpendicular to each other? " In this way, students here must be eager to know the answer and wait for the next class to pave the way for the next class.
Mr. Ye Shengtao said: "The end is where the article is finished, but the most taboo at the end is that it is really finished." Therefore, excellent teachers often use the method of setting suspense at the end of teaching. It makes students come to an abrupt end when they want to know what will happen next, thus leaving students with an unknown number to be explored, arousing students' strong desire to learn new knowledge and making "listening to the next chapter" their learning expectation.
