Often, students are tired of learning and play truant because they can't keep up with their math scores. It is difficult to improve the teaching quality, which is necessary for math teachers.
The theme of the study. So, the interest of teaching content, the integrity of knowledge, the logic of teaching and the accuracy of language? over here
The change of students' thinking at an age stage has a positive effect.
In teaching, it is the contradiction between teaching and learning, and the teacher is the main aspect of the contradiction, and the teacher plays a leading role in teaching. Therefore, teachers should first seriously understand the importance of mathematics teaching in junior one, and strive to do the following work in teaching.
First, use reasonable teaching methods to realize the smooth transition from primary school to junior high school.
Freshmen in senior one just bid farewell to the learning mode of primary school and began to change from the passive subordinate position relying on parents and teachers to the active position.
Change. Therefore, we should grasp the following two aspects in teaching:
1, pay attention to the change of teaching methods. The characteristics of primary school students' memory are mainly mechanical memory. Therefore, on the one hand, in teaching
Continue to develop their mechanical memory ability; On the other hand, pay attention to cultivating students' ability to remember meaning; Instruct students to remember the prescription.
Legal choice.
2. Pay attention to innovation and reasonable guidance. In view of students' curiosity and freshness, when teaching some new courses, it is advisable to
When choosing some novel, interesting and challenging questions as the introduction. For example, in the teaching of rational number subtraction, students should first learn.
Calculate 5-3, 8-3, 70-30, and then display 0-8, 5-6, 30-90 and so on. Deliberately set suspense, let students think and mobilize learning.
Students' desire to solve problems and their use introduce the theme of this lesson.
Second, cultivate students' "four abilities" in teaching.
Mathematics in senior one is difficult, and there are many exercises, so many students can't adapt immediately. Therefore, if students want to realize the transition from primary school to junior high school as soon as possible, they must work hard to cultivate and train their listening, watching, thinking and speaking.
1, there will be a class. Teachers should teach students the skills of "listening" in teaching? Concentrate on important or unfamiliar places. For example, when explaining the chapter of solving a quadratic equation with one variable, let students listen to the guiding ideology and methods of solving problems. These two points are the focus of this lesson. If students focus on these two points? The teaching effect will be very significant.
2. You can read. Ordinary students are not interested in reading mathematics textbooks, eager for success, only looking at the results, not at the process, easily ignoring the conditions, scope and derivation process of concepts, only knowing what is and not knowing why. Therefore, teachers should adopt different methods to guide students to read patiently, such as speaking before reading, speaking while reading, practicing before comparing or reading before discussing.
3. Think about it. It is a method of mathematical logical thinking. Because mathematics is very logical, students should be taught to compare and divide.
Analysis, synthesis, abstraction, generalization and reasoning.
4, can express. It is to train students' language expression ability purposefully. Because students' expressive ability is different, some
When I expressed it, I was flushed and didn't express my meaning. Although I know it in my heart, I can't pour water with ice in my mouth. At this time, teachers should
Patiently encourage and guide, not criticize and ridicule.
Second, strengthen the cultivation of computing ability.
1, improve the computing power. It is difficult for junior one students to operate rational numbers. The reason is that arithmetic has formed a mindset for a long time, and students must be guided to distinguish between rational number operation and arithmetic operation. Rational number operation consists of "attribute symbol" and "absolute"
"Duality" consists of two parts. Arithmetic operation does not need to consider symbols, so it emphasizes symbol consciousness, and only follows the algorithm closely.
Only by being familiar with life and doing addition, subtraction, multiplication and division can we have a smooth transition. In fact, among many laws, the law of addition is the most basic and important: the two symbols are different.
The addition of numbers is the key. On the contrary, the subtraction of numbers may be converted into addition. On this basis, the symbols of multiplication, division and power
It is easy to determine the number, and the mixed operation of rational numbers requires rationality, standardization, accuracy and speed, but students are prone to make mistakes. Through the guidance of typical examples and exercises, we can teach students to examine questions, help them distinguish the operation order, find out the causes of errors, test the structure of analytical questions, and improve the calculation level step by step.
2. Summarize the operation skills in time. Summarize the learning experience of the same content according to the intelligence and achievements of junior one students. such as
Through learning, most students have mastered the rules of "removing brackets" and "adding brackets", but due to insufficient attention to the rules, they often make mistakes carelessly. To this end, I instruct students to compare these two rules and read them repeatedly, so as to promote students to use these two rules in Putonghua.
The unified form is: "remove brackets, add brackets, remember the rules well, don't forget, add positive brackets, constant symbols, and add negative brackets."
, all the projects have changed. "
Third, establish an interactive relationship between teachers and students.
Mathematics teaching is the teaching of mathematics activities and the process of communication, interaction and development between teachers and students. The interaction between teachers and students in teaching is actually a way for teachers and students to get to know each other with their own fixed experience. In traditional teaching? The focus of teachers' goals is to change students, promote learning, form attitudes, cultivate personality and promote skills development, and complete the task of socialization. The goal of students is to change themselves as much as possible and accept socialization through prescribed learning and development. Only by narrowing the difference in this goal can it be conducive to the achievement and realization of teaching goals.
1. First, teachers are required to change three roles. From traditional knowledge givers to participants, guides and collaborators in students' learning, from traditional teaching dominators and controllers to organizers, promoters and instructors in students' learning, from traditional
Static knowledge owners have become dynamic researchers.
2. Secondly, teachers are required to practice teaching with new roles. This requires teachers to get rid of the old custom of respecting teachers and valuing morality, and establish interpersonal relationships with students.
The equal relationship on the grid, walking off the platform, approaching the students, talking and communicating with the students on an equal footing, requires teachers.
Students discuss and explore together, and encourage them to think freely, ask questions freely, choose freely and even act freely. Try to be a student's concern.
Ask questions. As active participants, they exchange opinions and ask teachers to establish emotional friendship with students so that students can feel it.
The teacher is their close friend.
Fourth, create a life-oriented learning situation.
Mathematics teaching activities should be based on the development of students. Students' personal knowledge, direct experience and real world should be regarded as important resources for mathematics teaching. Therefore, creating students' learning situation can not only stimulate students' interest in learning, arouse students' curiosity, and urge students to change from "curiosity" to a strong thirst for knowledge, but also activate students' thinking, so as to enter the best learning state as soon as possible. For example, when teaching isosceles triangle in the first grade, you can create such a situation to show a group of cabins, pyramids and various decorative patterns. Let the students find the isosceles triangle in life. The purpose of designing the above situation is to let students appreciate and experience the wide application of isosceles triangle in real life. On this basis, recall the concept of isosceles triangle learned in primary school, and make necessary preparations for exploring the nature of isosceles triangle. In this way, students will soon enter the best learning state and actively participate in classroom learning? Carry out practical inquiry activities on problems.
In short, in the teaching practice of the first grade of junior high school, teachers should fully grasp the psychological characteristics of students, take various measures simultaneously, teach students in accordance with their aptitude, give full play to students' subjective initiative, improve students' comprehensive skills in learning mathematics, and lay a solid foundation for them to learn and master more advanced mathematics knowledge.
