Mathematics plays an increasingly important role in social production and construction. Practice has proved that you can understand and operate well.
Students who use mathematics will have more opportunities, and their mathematical ability will open up a broad future for students. Vocational Education in China
To expand the scale of education, the Ministry of Education should
2007
Regulations on running secondary vocational education and general education in senior high school in
Generally speaking, popularizing high school education depends not only on developing general education, but also on vigorously developing secondary vocational education.
It can be seen that mathematics education in vocational high schools not only faces the challenge of directly providing more workers with higher mathematics literacy for social development,
But also lay a good foundation for some students to receive higher education.
For a long time, mathematics teaching in vocational high schools has been deeply influenced by mathematics teaching in ordinary high schools. With the progress of the new curriculum reform
With the implementation of the new curriculum and the promulgation and implementation of "Mathematics Curriculum Standards for Ordinary Senior High Schools", the new curriculum has put forward many very good mathematics education.
These basic ideas also play an important guiding role in curriculum reform and classroom teaching in vocational high schools.
However, due to the universality, particularity and complexity of the object of vocational education, combined with my understanding in teaching for several years, I think
In the process of curriculum reform and classroom teaching in vocational high schools, we should pay special attention to the following three aspects.
First, "popularizing mathematics" should be implemented more generally and concretely.
After studying mathematics for three years in junior high school,
Students' mathematical ability has been initially differentiated.
Among the students who enter vocational schools,
Most of them are separated from the senior high school entrance examination. Although the mathematical foundation is uneven, it is generally poor. Habit, confidence,
Ability and so on are different. Therefore, different students should be treated differently as long as they can be on the original basis.
Just develop. The content of the compulsory course of the new curriculum puts forward: to meet the basic mathematics needs of future citizens and to enter the first year for students.
Step-by-step learning provides the necessary mathematical preparation. This is more instructive to the curriculum setting of vocational high schools.

How to treat the foundation and universality of mathematics curriculum in vocational high schools?
2
The role of mathematics in all walks of life has largely explained that mathematics is an indispensable part of a person's quality.
Especially with the popularization of computers, mathematics is closely linked with social life. So mathematics has become
Part of my personal life.
But what is the most basic,
What mathematical knowledge should each student master and be able to master? If you only know
Starting from knowledge and not from the actual situation of students, this problem will never be solved. From the content of mathematics teaching
Speaking of each content, it trains students' thinking more or less and improves their ability in a certain aspect, but this kind of mention
Height is implicit and cannot be measured directly.
For most vocational high school students, what they face after graduation is the employment problem. Therefore, the author believes that, first of all, we should
In-depth investigation of students' mastery of mathematics knowledge, and then determine which courses are compulsory and which are optional; each
The development of a major puts forward different requirements for mathematics, and at the same time, students' learning ability should be considered, and they should be treated differently and not too deeply.
Knowledge that is too difficult may not be needed.

How to deal with the relationship between mathematical tradition and mathematical popularization
?
New curriculum reform,
It is required that our mathematics teaching should realize that everyone can learn useful mathematics.
Everyone has mastered the necessary mathematics,
Let different people learn different mathematics,
Get different development in the learning process,
This is the so-called
"popular mathematics"
Especially for the students in our vocational high school, they don't need to master comprehensive knowledge like ordinary high school students, which requires me.
In the process of mathematics teaching, students should:
(
1
) emphasize application and practice so that everyone can learn useful mathematics.
We should not confine our teaching to book knowledge. Collect more examples of mathematics application in daily life.
Cultivate students' understanding and experience of mathematics application, and let students practice the extensive application of mathematics. Learn numbers from life.
Learning, so as to apply the learned mathematical knowledge to life. For example, our school just held a basketball match in Class 0/0 or Class 20 of Grade 3/KLOC.
Competition, from which we can solve the following math problems: There are 20 classes in the school taking part in the basketball game, and there is a game between them. How many?
Less games? Through practice and application, students have learned the necessary mathematical knowledge.
(
2
) emphasize the process and methods so that everyone can master the necessary mathematics.
In the process of new curriculum reform, one
Change the past practice of seeking results without asking about the process, and strengthen the problem-solving for students.
Check the process and the method to solve the problem. In the process of students' cooperative inquiry, teachers don't tell students the answer directly, but
Through the whole-hearted participation of students,
Personal practice,
Experience it for yourself,
Let students get all-round development in the process of exploration.
For example; In our life, we should surround a vegetable field in the open space by the wall. The length of the fence is fixed. How to surround it?
Want to maximize vegetable fields? All students should master these necessary mathematical knowledge. Therefore, in teaching, teachers
Let the students understand the problem by themselves. Through the process of students' independent inquiry, let students understand.
Solve problems so that everyone can master the necessary mathematics.
(
three
) Emphasize individuality and development, so that different people can learn different mathematics and get different development in the learning process.
The new curriculum requires us to let students speak freely in learning, not to suppress students' personality, but to pay attention to students' personality.
Make public, so that students' personality can be fully and comprehensively developed. In the teaching process, because of each student's interest and love.
Different people have different feelings about mathematics. Different people have different feelings and values.
To. Our teachers should respect students' different feelings about mathematics and pay attention to students' different feelings when solving problems.
Application of the solution. Those who have a good foundation can put forward more positive requirements and let them study and explore at a deeper level.
three
If the foundation is poor, let them know the most basic problem-solving methods to achieve their goals.
Second, we should emphasize interest in the course.
The new curriculum advocates "people-oriented" and increasing the interest of teaching materials is the concrete embodiment of people-oriented
Vocational high school students generally have poor mathematical foundation, poor study habits and weak interest in learning. How to eliminate the rights of students
What about the fear and resistance of learning mathematics? The most important thing is to stimulate students' interest in learning. Well, first of all,
Change their idea that mathematics is boring, and let them realize the fun and beauty of mathematics.
1.
Create scenes that students are familiar with and realize assimilation and adaptation of knowledge.
Constructivism holds that everyone learns knowledge by integrating new knowledge into original knowledge in his own way.
In the knowledge structure, teachers can change learning conditions, especially external conditions, to a certain extent. Teaching is
These external conditions are arranged and controlled by teachers. What is difficult is which situations students are familiar with and easy to accept.
Yes, most teachers have turned mathematics into pure "mathematics". To create scenes that students are familiar with, they should
We should communicate with students frequently to understand their thoughts and living conditions, and at the same time pay attention to extracting mathematics from the phenomena around us.
Problems, get information about production and life from newspapers and other media, extract mathematical problems, and find them from other disciplines.
Problems related to mathematical knowledge. This actual mathematical scene not only contains rich mathematical ideas, but also embodies numbers.
The essence of learning embodies the characteristics of mathematics, and because students are familiar with mathematics and are prone to curiosity, it is easy to attract learning.
Pay attention and let the students think positively. In this process, special attention should be paid to stimulating students' cognitive conflicts and deepening their study.
Understanding of life.
2.
Reflect mathematical culture and strengthen the teaching of mathematical history.
The cultural purpose of the new curriculum: the main factor of spreading human culture. Mathematics is a subject developed in human civilization.
What is developed in the process of exhibition depends on the development of the mathematical system itself and real life.
Objective needs. In the development of mathematics, how many tortuous, bizarre and touching stories have happened, which is thought-provoking.
Aftertaste, inspiration, teaching. Our mathematics teaching completely ignores the process of mathematics being discovered and created.
Just a bunch of conclusions and facts, what students see in the learning process is always so perfect, accurate and static.
Mathematics, and the historical and humanistic things in mathematics can also be said to be the most important things omitted. This is even more difficult.
Learning is covered with a cold coat, and it is understandable for students to stay away. Therefore, to understand mathematics.
Interesting historical facts and stories in the process of building knowledge permeate the teaching process, which is helpful for students to understand beauty and mathematics.
In-depth study of ideas, thus stimulating their confidence and interest in learning mathematics.
3.
Practical mathematics.
The new curriculum advocates "active and inquiry learning" and holds that students' mathematics learning activities should not only
Limited to acceptance, recitation, imitation and practice, we should also advocate self-study methods such as independent exploration, hands-on practice and cooperation and exchange.
One of the basic characteristics of modern learning style is "experience", which emphasizes physical participation and attaches importance to direct experience. Correct position
For students in vocational schools, one of the reasons for poor math foundation is that abstract logical thinking has not been fully developed, so they are studying.
In the process of learning, action-oriented teaching should be fully carried out to give full play to their action representation and image representation.
Use to form the most advanced symbolic representation service. In this process, students realized how mathematics developed.
Now, in the process of creation, experience the attempt, failure, failure and success in the process of creation, and experience the excitement and success.
four
Joy, everyone practices their understanding of mathematics in their own way, which will not only arouse interest,
But also to form their good world outlook and strong will.
So it is used in vocational high schools.
Mathematics Learning mathematics should become a very important form.
Third, application is the soul of vocational high school mathematics.
Improving students' ability to solve problems with mathematics can be said to be the core and ultimate goal of curriculum reform in every country.
Mark. For mathematics teaching in vocational high schools, due to the particularity of vocational education, we should strengthen the teaching of mathematics application.
study Therefore, we should pay attention to the reform of mathematics curriculum in vocational high schools: because some students who enter vocational schools directly go to work.
, will face different requirements of different industries: some industries are closely related to mathematics, such as
information technology
Industrial, electronic and electrical engineering
Industry; In some industries, there are not many opportunities to use mathematics, such as tourism and business. And different industries
The importance of mathematical knowledge is not the same, for example, the computer industry will have higher requirements for algorithms, while business
The main emphasis is on profit and optimization. The other part of the students who enter the university for further study, because of choice.
Different majors will also face different requirements in mathematics. But they all need vocational high schools to work for them.
Different lay the foundation to adapt to their future. Therefore, we must first deal with the mathematical knowledge needed by various majors at present.
And the mathematical knowledge needed for the further development of this major,
Determine that in the vocational high school stage
What must be taught,
What can be taught.
For example:
Four operations are used in business,
Linear programming,
Estimation, optimization problems, calculus (derivation), probability statistics (estimation) and other mathematical knowledge. With society
With the development of mathematics and the continuous development and improvement of majors, new contents related to mathematics should also enter teaching in time.
Rong. For example, at present, shopping malls implement seasonal discounts, and some businesses will discount the price of their products, which is actually a discount.
How much is the deduction? How to calculate the profit rate? How to combine these commercial behaviors to analyze the relationship among cost, bid price and selling price?
Let students know how to calculate the profit and loss rate and discount rate. Another example is the various loan methods and repayment methods in society.
Combination and selection,
Can students make a rational understanding and recognition of them? This is real life and everyone's business.
Closely related things. Others are related to specific majors, such as computer students studying arithmetic.
Series, may wish to guide them from the optimization of the algorithm, if each major students are also learning mathematics.
Knowing the specific content of this major not only enhances their interest in learning mathematics, but also makes them interested in the future.
Know the occupation to be engaged in and achieve the goal of killing two birds with one stone.
In a word, the implementation of the new curriculum has raised brand-new problems for all our teachers, and also pointed out our direction of efforts.
The direction of force is also a brand-new challenge. Therefore, the research on the reform of mathematics curriculum and classroom teaching in vocational high schools is only
Only by constantly exploring and trying in practice can we achieve better results.
