First, the implementation of the "student-oriented" educational philosophy
The object of teaching is students, and students are the main body of teaching. To realize effective teaching in mathematics teaching in secondary vocational schools, we must first recognize the students' situation, really start from the students, and start from the reality that "students don't want to learn", and teach with students as the main body; Second, prepare lessons according to the students' situation, analyze the teaching materials, decompose the content, reduce the difficulty step by step, and make the classroom teaching conform to the students' cognitive level and suit their learning foundation; Third, design teaching around students, start with what students have seen and heard, introduce what students are interested in, seize students' curiosity, attract students' attention, stimulate students' interest in learning, and let students fully participate in classroom teaching and become the masters of classroom learning; Fourth, guide all students to take active actions, listen carefully, think actively, learn knowledge, master skills and develop their body and mind.
Second, building a harmonious classroom
The effective implementation of teaching needs a harmonious classroom atmosphere. Teachers should fully consider the available resources of the school, combine the actual situation of the class, base on the actual level of students, scientifically make teaching plans, create teaching atmosphere and optimize teaching effect. Various methods of scene introduction can create a harmonious learning atmosphere. For example, "collection" can be used as a collection, which is convenient for students to understand and enhance the sense of collective honor.
Combining students' foundation and teaching content, flexible teaching methods are adopted. The new teaching mainly inspires students to design a series of problems, and gradually inspires students to find problems and actively analyze, study and solve them. Exercises class tests and competitions are mainly used to guide students to solve problems carefully, think comprehensively and cooperate independently. Summarize the review class, guide students to compare and classify, learn to transfer and use knowledge, and help students become the masters of learning and the main body of classroom teaching.
Teachers and students interact and respect each other, thus turning the classroom of imparting knowledge into a classroom of communication between teachers and students, making the lifeless classroom full of vitality and creating a relaxed and happy classroom situation and interesting learning atmosphere. In a harmonious and relaxed classroom, change "I want to learn" into "I want to learn" and "I hate learning" into "I like learning" to effectively improve the effectiveness of mathematics classroom teaching in secondary vocational schools.
Third, solidly carry out classroom teaching.
(1) Pay attention to double-base teaching, consolidate basic knowledge and strengthen basic skills.
Mathematics in secondary vocational schools is a basic subject in secondary vocational education, and the basic concepts and basic problem-solving skills of mathematics are still the key contents.
Concept teaching should be pragmatic, and the explanation should be correct, accurate and clear. Identify the key elements of concepts, emphasize key words, and find the connections and differences between similar concepts. When expanding, we should be comprehensive and in-depth, pay attention to changes and highlight characteristics. For example, in the teaching of conic curve, the definition of a circle is the set of points on the plane with a fixed distance from a fixed point. Guide the students to grasp that the circle is a plane figure, which is different from the ball, and learn the rotating body of solid geometry. A circle is a set of points with the same properties. Contact the definition of set to deepen the understanding of set. These two points can be used as the same point when learning the definition of conic curve in the future, which can help students reduce their learning difficulty. Two other points: to a fixed point and a fixed length are different from other conic curves. The definition of ellipse becomes easy to learn.
Skills teaching should pay attention to practical results, be simple and practical, and be convenient for students to understand, remember and master. Help and guide students to analyze and summarize the steps of solving problems. Pay attention to cultivating students' application ability and adaptability. For example, when solving the specified item in binomial expansion, guide students to sum up the steps: (1) Write the general formula; (2) finishing; (3) solving k according to conditions; (4) Return the k-generation term and find the result.
(b) Analysis and demonstration should be practical.
The analysis of examples should be meticulous, clear about what is known and what is sought, distinguish the number of conditions and their relationship, link with what is sought, pave the way for bridging, step by step, and cultivate mathematical thinking and thinking. Argumentation should combine teaching materials, write norms, analyze key points, combine norms with flexibility, and write clear steps. Students should be encouraged to solve problems in multiple ways, open their minds, and think and solve problems from multiple angles.
(3) Exercise and homework should be appropriate.
Practice should be chosen according to students' learning situation, so that students can apply and consolidate the knowledge and skills they have learned in time, and at the same time, students can experience the joy of harvest, gain a sense of accomplishment and actively learn new knowledge. Homework should be representative, arranged in layers, carefully corrected, and promote the all-round development of all students.
(d) The review summary should be concise.
The knowledge learned should be highly summarized in concise language, so that students can master the knowledge learned accurately and firmly. For example, the word "tune" summarizes the symbols of trigonometric functions in different quadrants: the first "horizontal" painting indicates that the sine function of the first trigonometric function is positive in the first and second quadrants; The second vertical (hook) diagram shows that the cosine function of the second trigonometric function is positive in the first and fourth quadrants; The third diagram shows that the tangent function of the third trigonometric function is positive in the first and third quadrants.
Fourthly, we should learn from each other in teaching.
(A) students get growth
Classroom is not only a place for students to learn, but also a place for students to communicate. In an effective classroom, students not only learn knowledge, but also learn to communicate and cooperate, and at the same time cultivate the ability of cooperative inquiry, which is conducive to the healthy growth of students' personality and psychology.
(B) teachers get growth
Effective classroom will promote teachers' continuous learning in the teaching process, not only to further understand the teaching content, exercise teaching skills, explore teaching methods and gain valuable experience, but also to learn a lot of extracurricular knowledge from students. For example, when studying space solid geometry, I found that students were interested in dimensions, so I introduced the knowledge of zero-dimensional, one-dimensional, two-dimensional, three-dimensional, four-dimensional and multi-dimensional spaces, and the students talked about it. Students also suggested that I go to see a sci-fi movie "Once Home" and look forward to continuing to communicate with them. This class not only stimulates students' interest in learning solid geometry, but also cultivates students' idea of dimension reduction in advance, and also stimulates teachers' new interest in four-dimensional space.
(C) the growth of teacher-student relationship
In the classroom, teachers are full of love, patience and care for students. Students "love their teachers and believe in their ways", and the relationship between teachers and students is intimate and harmonious. Students love learning more, and teachers love classes more. The classroom has become a place where teachers and students look forward to communication.
Efficient classroom teaching is the eternal pursuit of every teacher. Mathematics teachers in secondary vocational schools should really take students as the main body, combine majors, build a harmonious classroom atmosphere, purposefully integrate teaching ideas, teaching concepts and teaching contents into classroom teaching, and carry out practical teaching in a down-to-earth manner, so that teachers and students can develop together and realize effective teaching.
