1Improve the effectiveness of vocational high school mathematics teaching researchPapers to write Net: Abstract: The author of teaching practice experience and learning from the experiences of others to start, for employment-oriented culture of secondary vocational education Teaching math requirements. Proposed to let students learn the necessary, sufficient and valuable teaching knowledge, based on the results. Making mathematics teaching become popular, close to the professional, diversified. Employment for students ready to do mathematics, and thus significantly improve the effectiveness of vocational high school mathematics teaching. Keywords: high school students the effectiveness of mathematics Vocational high school and high school teaching in mathematics has a great difference. Math class in high school as a main subject, the students a good foundation, strong interest in learning, while the vocational high school math courses as a tool, for specialized services The most basic difference between students, understanding of 2comprehension is low. Lack of enthusiasm for mathematics. Not interested, so are afraid of math, learning to lose confidence, do not want to learn to learn from fear. This is a vocational school students in mathematics learning that exist in the more general problem. Also teaching in a certain degree of difficulty. How to make these basic learning difficulties, weak or vocational school students on the right track, to the good momentum of development, how to improve the effectiveness of vocational high school mathematics teaching, has become a priority in every mathematics teacher in front of the subject, I combined several years of vocational high school mathematics teaching practice, talk about their experiences. Junior high school and vocational high school focusing on the interface between mathematics teaching Junior high school and vocational high school knowledge of mathematics teaching materials need to make many of convergence, such as: the proposition, the function of the generous concept, mapping and confrontation, quadratic inequalities, and linear inequalities in one, three-dimensional geometric line line, line and plane, things to 3parallel and perpendicular plane geometry in line with the parallel and perpendicular lines, dihedral angle, and plane geometry, analytic geometry and algebra of linear equations in a function . high school . some of them new content, some knowledge of the old junior high school, so in teaching junior high school not only to pay attention to the knowledge of the review, but also should pay attention to clarifying the difference between old and new knowledge and contact, timely and analog penetration into the mathematical ideas and methods to help students learn new things. just started to slow down the progress of teaching appropriate, By contrast Lenovo, review middle knowledge, a clear concept of internal relations, knowledge of the convergence, so that the gradual deepening of learning to adapt to the rhythm of vocational high school math teaching so that students in the review on the basis of old knowledge, happy to accept new knowledge, to learn other laid a good foundation for specialized courses. Need to build professional mathematics teaching system Vocational high school mathematics teachers respond to professional needs now used in all mathematical 4knowledge and to further develop the professional knowledge of mathematics required to make a detailed investigation to determine what vocational high school mathematics is to be taught and what mathematics is to teach introductory, while still with the Professional Teachers established channels of communication, understanding of math content for the time period required for the professional and focus, so according to professional needs, carefully select or preparation of teaching materials, to adjust the teaching content and teaching key to re-build a new professional needs-based mathematics teaching system. adjustment process may not have too much emphasis on the integrity of the systematic mathematical knowledge, the key is to highlight the practical and vocational school mathematics through investigation to determine the service I The focus of the professional: the accounting profession to learn to function, the initial probability and statistics such as knowledge-based, electronic e-learning professional angle to the knowledge-based functions and complex numbers, etc.; machinery (including numerical control professional) should study three-dimensional geometry , plane geometry, trigonometry and other knowledge-based: computer science 5students in learning arithmetic progression, may wish to guide them from talking about the optimization algorithm: The main focus is tourism professional computing and profit optimization in planning, while with student has less content expertise can allow students a general understanding, teachers unnecessary depth
