First of all, update teaching concepts and change teaching methods.
In the current middle school mathematics teaching, in order to pursue the enrollment rate unilaterally, teachers usually have to work overtime to make up lessons for students and engage in sea tactics, which greatly increases the academic burden of students and hinders their healthy physical and mental development. In the end, only some "top students" with high scores and low energy can be cultivated. Therefore, education must change from exam-oriented education to quality education, that is, from the concept of imparting knowledge and teaching for grades to cultivating ability, tapping potential and teaching students learning methods. In teaching evaluation, judging the teaching effect from the mastery of a certain section of knowledge is transformed into judging the students' intelligence level. In terms of teaching quality, the concept of teaching quality has changed from simply measuring teaching quality by academic performance to improving comprehensive ability. On the teaching subject, the change from teacher-centered to teacher-centered and student-centered makes it clear that the role of teachers lies in cultivating students' learning ability and self-education ability.
Second, reform teaching methods and use teaching media.
As we all know, classroom teaching is the main position to implement quality education. Teachers should first renew their ideas, change outdated and backward teaching methods, and put the ideas and methods of educational reform and innovation into daily education and teaching work. Modern teaching media has the characteristics of intuitive and dynamic image, which makes up for the deficiency of traditional teaching mode and makes students' thinking ability develop to a higher level. Therefore, in order to improve the effectiveness of 45-minute mathematics classroom teaching, it is imperative to apply modern teaching media. The author explores the application of computer-aided teaching in junior high school mathematics classroom teaching, and stimulates students' brains from different angles and aspects through computer video, audio, pictures and audio to strengthen the dissemination of teaching information. For example, in the class of similar triangles, in order to let students correctly grasp similar triangles's judgment law, I used flash mathematics teaching software, which made students easy to learn and understand, and made them memorable, which broke through the teaching difficulties and improved the classroom teaching efficiency.
Third, teaching students in accordance with their aptitude and at different levels.
There are great differences among students, so teachers should treat different students differently.
For students who usually have good study methods, habits and grades, they are generally only given guidance on specific issues, and the training difficulty is appropriately increased. For example, these students are assigned a "daily problem" outside their homework, asking them to try their best to solve the problem and encouraging their innovative thinking. For students with correct learning attitude and diligent but average grades, they generally focus on the guidance of learning methods, check their study notes regularly, and explain the examples of "good questions and wonderful solutions" by chapter, so as to enhance their understanding of concepts and help broaden their thinking of solving problems. For students with good intelligence, but strong randomness and hard study, we should focus on educating and adjusting their learning quality, giving them the opportunity to be responsible for completing a certain task, enhancing their sense of responsibility and cultivating their attitude of serious study. For a few students with serious learning problems, the strategy of non-stimulation, low requirements and slow enlightenment is generally adopted to maintain good discipline in the classroom. Fourth, attach importance to scientific inquiry teaching and cultivate students' autonomous learning ability.
Scientific inquiry teaching is the hot spot of current teaching reform. Scientific inquiry is a learning mode and process in which students acquire knowledge, skills and methods through inquiry activities such as finding problems, asking questions, investigating and researching, hands-on operation and expressing communication. Inquiry teaching method requires teachers to change the traditional teaching mode with teachers as the main body, students as the auxiliary, books as the main body and experiments as the auxiliary, and pay attention to students' active participation in the teaching process. In junior high school mathematics textbooks, there are many contents that can be taught by inquiry method. Mr. Tao Xingzhi said, "I think a good teacher is not teaching, but teaching students to learn." At present, in mathematics teaching, the phenomenon of attaching importance to teaching and neglecting learning is still very serious. Teachers only focus on teaching without instructing students how to learn, which leads to low learning efficiency and is not conducive to the improvement of students' ability.
While imparting knowledge, teachers should enable students to master certain learning methods and acquire the ability to choose and use appropriate learning methods in a specific learning environment for effective learning. Learning method guidance not only enables students to learn, but also enables students to learn, be good at learning and be good at learning, so that students can get rid of the shackles of fighting for time and physical strength and become masters of learning rather than slaves of books. Therefore, teachers should pay full attention to the guidance of learning methods.
According to the process of mathematics learning, guide students to preview, listen to lectures, review and consolidate their homework;
1. Preview guide
"Everything is established in advance, and it will be abolished if it is not planned." Whether you have good preview habits is an important prerequisite for the smooth progress of your study. Cultivating good self-study habits is not only the need of immediate study, but also the need of future work, so we should pay attention to it. Generally, you should preview the math content you want to learn the day before and read the text word for word. For theorems, formulas and other important contents, we should not only remember the conclusion but also pay special attention to the reasoning process. Use both hands when previewing, use your brain to write down difficult questions, so as to attend classes with questions and improve the efficiency of attending classes.
2. Classroom teaching
With adequate preparation, attending classes will become easy and efficient. First, pay attention to the requirements of listening purpose, listen to the introduction and formation process of knowledge, listen to the teacher's analysis of key and difficult points, listen to the analysis ideas of solving problems, and listen to the summary. Second, we should pay attention to thinking while listening to the class, be good at asking questions boldly, and generate associations and guesses from listening. The third is to record, remember the main points, doubts, ideas and methods of solving problems, and remember the summary and thinking after class.
3. Review and homework consolidation guidance
Instruct students to put review before doing homework: read textbooks, remember what is taught in class, strengthen understanding, consolidate memory, and then finish homework independently. In the writing format of homework, the demonstration role of teachers is extremely important. It is necessary to guide students to write in a standardized way, so that the organization is clear, the handwriting is clear, and standardized graphics are drawn.
In a word, the core problem of junior high school mathematics classroom teaching reform is how to organically combine teachers' teaching with students' learning. As a class teacher, in the whole process of mathematics teaching, we should organically unify our own teaching methods and guiding students' learning methods to achieve the optimization of teaching, so as to get twice the result with half the effort.
