Several methods of mathematics teaching
First, pay attention to the learning environment and let students participate in mathematics teaching.
In the discussion class, teachers carefully design discussion questions, give reasonable guidance, and discuss and learn among students.
Second, pay attention to the problem situation and let students get close to mathematics.
In mathematics teaching, teachers should carefully create problem situations, stimulate students' enthusiasm for learning new knowledge, narrow the distance between students and new knowledge, and let students get close to mathematics.
Third, pay attention to hands-on operation and let students experience mathematics.
Teachers design mathematics teaching as tangible materialized activities, so that students can have a clear understanding of very abstract knowledge, and the experience gained by students through hands-on operation is very profound.
Fourth, pay attention to independent exploration and let students? Reengineering? mathematics
When students have doubts about what they are interested in and are eager to know the mystery, teachers should not simply teach what they know directly to students, but should fully believe in students' cognitive potential, encourage students to explore independently, and actively engage in mathematical activities such as observation, experiment, guess, reasoning and communication, so as to boldly? Reengineering? mathematics
Fifth, emphasize the application of life and let students practice mathematics.
In teaching, teachers should often let students use what they have learned to solve practical problems in life, so that students can master what they have learned in time in the process of practicing mathematics, such as explaining the stability of triangles, the instability of parallelograms and the rotation invariance of circles with mathematical knowledge.
Method for teach by using multimedia
First, the process of preparing lessons has changed from complex to simple.
In the process of preparing lessons outside, I always copy the teaching contents in the lesson plan book by consulting reference materials and teaching materials. In addition to textbook knowledge and reference materials, there are a lot of extracurricular knowledge provided to students through electronic lesson preparation. The lesson preparation content is also printed directly by the printer, and the content is simply added or deleted on the computer, which saves the lesson preparation time and makes the lesson preparation process from complicated to simple.
Second, the change of students' learning style.
In the traditional teaching process, the teaching content is always written on the blackboard in half cases, and students' learning mainly depends on memory, lacking a breakthrough in methods. With the use of multimedia teaching, students' attention has shifted from the blackboard to the TV screen, and the learning content has changed from boring words to beautiful images, pictures, sounds and animations, which has changed students from passive learning to active learning, from boredom to interest, and the change of learning methods has brought about changes in learning effects.
Thirdly, teachers' teaching methods have changed.
In the past teaching process, chalk filled the whole classroom, while multimedia was used for teaching, mouse replaced chalk, and screen replaced blackboard, which saved the time of writing on the blackboard in class and made the teaching process lively. Some abstract contents become intuitive through influence, and the change of teaching methods brings changes in the environment and teaching effect.
Generally speaking, the use of multimedia teaching saves the time of preparing lessons, increases the course content, improves students' interest in learning, broadens the teaching horizon, and gains little.
Return the classroom to the students-thinking and practice of junior high school mathematics classroom teaching.
How to improve the effectiveness of teaching methods
Classroom teaching process is an interactive process of mutual communication between teachers and students. Both teachers and students enter the teaching process with a positive attitude, which is the premise for students to actively participate in learning and achieve good teaching results, and also the main channel for junior high school mathematics teaching.
1. Pay attention to the cultivation of students' interest in learning and stimulate their enthusiasm for learning.
Interest in learning is the embodiment of students' learning initiative and the source of motivation for their learning activities. Throughout the ages, many educators have attached great importance to the cultivation, guidance and utilization of students' interest in learning. Confucius said: It is better to know than not to know. Explain? Studious? Importance to education. As teachers, what should we do? Fun? Lead the way? Love? Navigation. In teaching activities, teachers' teaching and students' learning are always more or less emotional, that is, educational emotion. Any student will have expectations for the teacher in the first class, mainly in the following aspects: expectations for the teacher's appearance; Expectation of teachers' etiquette; Expectations for teachers' classroom teaching. In teaching practice, we find that many students show great investment in their favorite teachers, interesting teaching contents and fascinating teaching methods, and their learning thinking will maintain a harmonious and perfect unity with the teacher's teaching. In this way, students learn to use knowledge to solve problems and experience the joy of success. As a junior high school math teacher, we should seriously study students' psychological tendency, cultivate students' thirst for knowledge in this way, guide students to form a good consciousness tendency, fully believe in each student's potential, and encourage each student to actively participate in learning.
2. Reform teaching methods and give full play to students' main role.
For a long time, there has been a serious problem in classroom teaching in many schools, that is, only paying attention to the relationship between teachers and students. Teaching? With what? Study? The neglect of communication and learning between students leads to the narrowing of students' autonomous learning space, which is manifested in the following aspects: the authority of teachers is above all else, and the requirements for students are too strict; The classroom atmosphere is tense and dull, lacking due vitality; How much the teacher teaches, how much the students learn, and what about the teacher? Lecture? , students? Will God listen? Single teaching mode violates? Take teaching as the leading factor and learning as the main body? Therefore, in order to give full play to students' main role, we must leave more space for students to study and discuss independently in the classroom, so that they have the opportunity to think independently, discuss with each other and express their opinions, and use the leading role of teachers to guide students to actively participate in the teaching process. Guide students to explore the whole process of the occurrence, formation and development of knowledge, let students learn to find and ask questions, and gradually cultivate students' ability to analyze and solve problems, thus stimulating students' strong thirst for knowledge and creativity and making them rational. Want me to learn? Arrive? I want to learn? Change and truly realize active participation.
3. Pay attention to the teaching of learning methods and cultivate students' learning ability.
Mathematics ability is actually the ability of students to listen, speak and think in mathematics learning activities. They are the premise and indispensable learning ability of mathematics classroom learning activities, and also the guarantee to improve the efficiency of mathematics classroom learning. Listen. That is, students should attend classes first, but also listen to their own understanding of mathematics knowledge and their feelings after class. This requires? Listen. Therefore, teachers should keep abreast of students' understanding of the main points of knowledge and the effect of lectures. At the same time, teachers can also teach students some listening skills. For example, how to maintain a high degree of concentration in the process of listening to lectures and synchronize your thoughts with the teacher; How to better understand the teacher's explanation; How to learn to summarize the main points and key points; What if you don't understand? When other students answer questions, they should also pay attention and actively participate in the discussion. Say? That is, students can describe what they have learned in their own language, explain the concepts in mathematics, discuss with classmates and ask questions from teachers, so that their views and questions can be easily understood by others. Think? Is to give full play to students' thinking? Free imagination? Are we done? What is the nature of a circle? After that, ask? Why do wheels have to be round? Let students give full play to their free imagination, feelings and experiences in imagination, which not only enlivens the classroom atmosphere, but also further consolidates what they have learned in imagination. Therefore, in classroom teaching, we should try our best to create conditions conducive to the formation of students' listening, speaking and thinking abilities, and constantly explore the rules and methods of training.
