Mathematics teaching activities are the main way to cultivate mathematics literacy. The comprehensive practical activity course of inquiry learning is an important way to cultivate mathematics quality. Teenagers' scientific and technological innovation activities are a good way to cultivate mathematics literacy. General technology course is also an effective way to cultivate mathematics quality. From the appearance of "double basics" teaching to the presentation, research and implementation of a series of concepts such as quality education, emotional attitudes and values, and students' core literacy, we can easily find that the implementation of educational and teaching objectives is concrete, clear and operable in the process of this change and development, which fully reflects the continuous deepening of scientific research in basic education and the continuous improvement of educational research level.
First, the cultivation of mathematical abstraction ability
Mathematics is a subject that integrates logic and abstraction. Abstraction is numbers.
One of the main characteristics of mathematics teaching is that the students who have just entered junior high school are not rich in abstract thinking ability, so it is necessary to cultivate students' abstract thinking ability.
It is an important link to cultivate students' core literacy in mathematics. The content of mathematics is abstract, for example, the form of space is abstract, and the quantitative relationship of examples is abstract, which makes students unable to understand ideas for a while.
This is obviously not conducive to the development of students' mathematics. If teachers monopolize the right to speak, too many suggestions will only make students develop inertia and cause thinking obstacles. For example, help
In order to help students understand the definitions of positive numbers and negative numbers, if positive numbers are defined as "positive numbers with positive signs in front" and negative numbers are defined as "negative numbers with negative signs in front".
Can these two definitions explain that they are positive numbers? Is it negative? Obviously not. If positive numbers are defined as "positive numbers greater than zero", negative numbers are defined as "negative numbers less than zero".
The definition of "number" will not cause one of the above, but also help students to clarify the concept and divide positive and negative numbers into left and right parts based on "0". student
Naturally, zero can be seen everywhere, neither positive nor negative, which is obviously more effective than rote learning.
Second, a correct understanding of the relationship between teaching and learning
Junior high school mathematics classroom teaching is a dynamic teaching form, which consists of teachers' teaching and students' teaching.
Learning is the basic form in this teaching process, and the purpose of both is to make students master the mathematical knowledge they have learned skillfully. For the teacher's teaching, its ultimate goal.
But also for students' study. In traditional teaching, teachers only consider the personal experience of attending classes, regardless of whether students are interested in learning, which leads to teaching effect and learning.
The effect is not ideal. In the mathematics classroom teaching in the form of quality education, teachers should correctly understand and grasp the relationship between teaching and learning, put the position of teaching in a correct position, and recognize the role of teachers.
Effectively handle the relationship between teaching and learning in mathematics teaching, actively cultivate students' interest in participating in classroom teaching, attach importance to and respect students, and cultivate students' problem consciousness and
The ability to solve problems, improve the effectiveness of teaching, in order to improve students' mathematics core literacy. In the classroom teaching of junior high school mathematics, if we want to cultivate and improve students' problem-finding.
To solve problems and cultivate and improve students' inquiry consciousness and ability, we must cultivate and improve students' autonomous learning ability. And the cultivation of students' autonomous learning ability.
It is necessary to optimize the design of teaching design and teaching process to lay the foundation for students to dare to ask questions.
The improvement of autonomous learning ability is also manifested in that middle school students can find problems, use their own mathematical knowledge to solve problems, and put forward solutions to problems in various ways.
Thirdly, the cultivation of expanding thinking in problem solving is highlighted.
The most wonderful thing about mathematics is its huge logical system, the logical body of the whole mathematics.
The system can cover almost all visible material calculations. For junior high school students, math subjects may be just knowledge instilled during class hours, and they are unaware of these classes.
When the content can be combined into a whole. If teachers can cultivate students' mathematical thinking in mathematics class, they can let students learn in the process of conquering classroom knowledge.
I will feel the satisfaction of climbing mountains, so I no longer think that mathematics is the source of fatigue after climbing mountains. In this regard, teachers can use the extended questions arranged after class to assist learning.
Students should develop their logical thinking ability. Here, take the problem of after-school expansion in the third class of Chapter 22 in the first volume of the ninth grade textbook as an example. The specific problems are as follows: use a paragraph with length l respectively.
The line segment of is surrounded by a rectangle or a circle, which area is larger? The teacher enumerated a quadratic function. If one side of a rectangle is a, the rectangular area s1= a× (l-2a)/2 = a1/2-a2, and the circle radius.
R=L÷2π, and the circular surface S2=π×(L÷2π)2=L2/4π. It is not difficult to see that the circumference determines that the area of the circle is fixed, and then combined with the image, the value when the rectangular area is the largest (when
When A=L/4), the rectangular area is the largest, and the problem can be solved by comparison.
Fourth, innovate teaching ideas and teaching models.
Cultivating students' core literacy in junior middle school mathematics classroom must innovate teaching ideas.
Integrate theory with practice. In the past teaching, many teachers did not pay attention to the design of mathematics curriculum, and most of the teaching models adopted were taught by teachers.
Students listen first, and then master the relevant theoretical knowledge according to the notes. In fact, in the front-line education and teaching, teachers should implement the concept of quality education, starting from the learning situation,
Optimize teaching design and constantly innovate teaching mode. Students will encounter math problems in their future study and work, and they should be guided to master the essentials in the teaching process.
Important theoretical knowledge, and at the same time participate in life practice, pure mathematics knowledge into common sense of life, improve their core literacy. Teaching practice has proved that if at first
In the process of mathematics teaching, students are blindly required to memorize and master relevant mathematics knowledge mechanically, so students can only get good grades in the exam, but their own scores are not enough.
Core literacy is difficult to improve. Under the new situation, teachers should innovate the teaching mode and adopt the methods of group cooperation, independent inquiry, flipping the classroom and micro-class.
Students' enthusiasm and initiative, at the same time pay attention to the cultivation of students' practical ability in life, and promote the improvement of students' core literacy in mathematics.
Under the background of new curriculum reform, teachers need to pay attention to the cultivation of students' mathematical core literacy.
Raise. Teachers can pay attention to knowledge orientation and cultural orientation through "curriculum design"; Classroom teaching, giving consideration to knowledge guidance and thinking inspiration; Teaching evaluation, examining mathematical thinking
And the cultivation of the core literacy of mathematics should be thoroughly implemented in every stage of junior and middle school students' mathematics learning, so that students can learn to count in a subtle way.
In the process of learning knowledge, form a good mathematical core literacy.
I hope this helps.
