Keywords:: secondary vocational students' mathematics literacy mathematics teaching
The goal of teaching in secondary vocational schools is to cultivate middle and primary technical talents and laborers with all-round development in morality, intelligence and physique, and comprehensive professional ability and quality. With the development of economy and society, mathematics has penetrated into many fields of economy, such as finance, trade and cooperation. Secondary vocational school students can participate in social life more effectively and meet the needs of economic construction and social development only if they have higher mathematical literacy, higher standard of quantitative awareness and the ability to communicate in mathematical language. Therefore, mathematics teaching in secondary vocational schools should strive to improve students' mathematics literacy, not only to provide students with the necessary mathematical tools for learning professional courses, but also to serve students' quality, so that they have the foundation and ability to continue learning and serve the future needs.
First, the role of secondary vocational students' mathematical literacy
Mathematics, as a cultural basic course for secondary vocational school students, not only has strong scientific value, but also has obvious moral and cultural value and good quality education function. Secondary vocational school students have good mathematical literacy, can actively explore and be good at grasping the background and essence of mathematical problems; Skillfully express your mathematical thoughts in accurate, rigorous and concise mathematical language; Have a good scientific attitude and innovative spirit, and put forward mathematical conjectures and concepts reasonably; After putting forward the conjecture, we use the rational thinking of "mathematical way" to explore ways to solve the problem from multiple angles; He is good at reasonably simplifying and quantifying the phenomena and processes in the real world and establishing mathematical models. Good mathematical literacy can help students better understand nature and human society, better adapt to daily life and understand the surrounding environment; It can promote students to think methodically, express and communicate effectively, and use mathematics to analyze and solve problems; At the same time, students' initiative, sense of responsibility and self-confidence can be cultivated through mathematical practice activities, and their scientific attitude of seeking truth from facts and the spirit of being brave in exploration and innovation can be cultivated.
Second, secondary vocational school students' mathematical literacy
There are various indications that there is an increasingly obvious gap between the mathematical literacy of secondary vocational school students and the growth and demand of talents, which cannot adapt to the development of economy, science, culture and people. Because of their poor mathematical literacy, their personal development and their due role in their jobs have been affected to a considerable extent, and the healthy development of secondary vocational schools has also been affected. There are many problems for secondary vocational school graduates after entering the society and working, such as the inability to correctly interpret charts and analyze relevant information, statistics and other basic knowledge, and the lack of simple economic forecasting and decision-making ability.
Tracing back to the source, the cause of these problems is still in the school, which lies in the cultivation of students' mathematical literacy.
The present situation of students' mathematics learning in secondary vocational schools is: there are many loopholes in learning, and the learning and memory of basic knowledge are ignored; Because of the generalization and abstraction of mathematics, there is an insurmountable gap between mathematics learning and mathematics application, which leads to students learning a lot of knowledge but not knowing how to use it. Students seldom feel the consciousness of self-need in mathematics. Only in the math class can they feel the existence of mathematics, or in the examination room can they feel its power, while on other occasions, they can't feel the existence and power of mathematics. Some students are tired of learning mathematics, and the less interested they are in it, the more boring they feel. There are still many students who are proficient in solving standard problems, but their ability to solve unconventional problems is relatively weak, and their creative thinking ability in mathematics is insufficient. There are many problems in professional study and study life, and they are not good at mathematicizing problems or using mathematical language accurately, which makes mathematics not an effective tool, but an obstacle to professional study. Thirdly, some suggestions on improving the mathematics literacy of secondary vocational school students in mathematics teaching.
In the final analysis, mathematics education is to improve all students' mathematics literacy, which is formed in mathematics learning. Therefore, in mathematics teaching, we must follow the laws of education and students' understanding, and do the following:
1, for all students. Facing all students is to be responsible for every student and make all students have the necessary mathematics literacy. When organizing teaching, we should proceed from the actual situation of most students and give consideration to students with learning difficulties and students with learning ability. In view of students' personality differences, we should teach students in accordance with their aptitude, guide them in different levels, and care for help, so that students with learning difficulties can achieve success and meet the basic requirements, and at the same time, students with learning ability can stand out.
2. Highlight the basic mathematical ideas and methods. "It is better to teach people to fish than to teach people to fish." In mathematics teaching, we should guide students to be good at observation, learn to think correctly, and know how to analyze, synthesize, summarize and summarize things. According to students' cognitive rules and the inherent characteristics of the subject itself, students should be consciously induced to think in multiple directions, angles and levels.
3. Learn basic theoretical knowledge well. In teaching, students should first correctly understand the basic concepts, remember the meanings of various symbols and letters, and study the laws of concept teaching; It is necessary to strengthen the teaching of formulas, pay attention to the introduction and derivation of formulas, the structural characteristics of formulas, the memory methods of formulas, the application and popularization of formulas, etc. We should understand the structure of knowledge and grasp the key and difficult points of knowledge.
4. Enhance students' thirst for knowledge. In teaching, teachers should use the charm of mathematics itself, the history of mathematics development and the wide application of mathematics to cultivate students' interest in mathematics. Teachers should carefully explore the materials, stimulate students' questions, encourage students to ask questions, support students to express their opinions, inspire students to find problems, ask questions and explore questions, and cultivate and stimulate students' enthusiasm for learning mathematics well.
5. Strive to improve students' ability to use modern information technology. Modern information technology with computer as the main body not only promotes the rapid development of science and technology, but also makes a qualitative leap in the application of mathematics. Students mastering modern information technology can greatly improve their mathematics literacy.
In a word, in mathematics teaching, we should not only effectively improve the teaching level and use emotional function to serve mathematics learning, but also cultivate students' sound personality and good personality in mathematics learning, which requires our unremitting efforts. As long as we follow certain laws, be good at digging and persevere, we will certainly cultivate talents with high mathematical literacy, sound emotions and high quality. ;
