Concept Teaching Of Middle And High School Function Under The New Curriculum The Study Of Convergence

The function is a core concept in the mathematics curriculum. However, as a result of function concept's abstractness and the complexity, it is also a middle school mathematics teaching difficulty. In the new elementary education curriculum reform, "Ordinary High school Mathematics Curriculum Standard" also set the new request to the function concept, new transformation from many aspects such as teaching goal, course content, study way as well as appraisal way. And so on Therefore the function concept's teaching is the topic which is worth discussing.This article is based on the function definition hierarchical, the overall evaluation function concept's historical development function concept's study must experience a long process, after the junior middle school, the high school two stages, the time span is big; The present teaching material is divided into two circulations (junior middle school, high school) to introduce, and takes the suitable seepage and the screw rise way, the partition has the circulation arrangement function knowledge, but the student's level is still low on function concept grasp. And in the foundation which the predecessor studies, through the questionnaire survey, they understand the different periods to the function the understanding degree, then from the junior middle school, the high school function concept teaching's engagement obtains, the exploration lets the function concept learning two stages be more perfect in logic and the understanding to be easier, a simpler more and direct way, and guides the student to form the correct function concept.This article from the following seven aspects proposed that the junior middle school, the high school function concept's teaching tactics and suggestion: 1st, complete the first time engagement work, let the students steadily cross the transformation in the function concept; 2nd, through function symbol's teaching, let the students realize the function symbol the significance. 3rd, the "concept of teaching" has always been run through inteaching. 4th, carry on the history of mathematics teaching, solved the problem that students are puzzled when they just to contact"the correspondence says"to"the variable says". 5th, improves the cognition to function concept by positive and negative example teaching. The atonement junior middle school"the variable says"influence which brings to the student.6th, the function concept's teaching and the information technology is conformitide, seeps the function concept to each domain. through function symbol's teaching, lets the student realize the function symbol the significance. 8th, the function concept applies in the life reality, not only lets the student the experience function concept essence, also lets the student academic society"study for the purpose of application". In the function concept teaching, I utilize these strategies, and made the remarkable progress, the student smoothly has not only completed from"the variable said that""the correspondence said"the engagement, had to the function concept's understanding dimly to the profound understanding, and also let the student learn to solve question at the same time with the function concept, realized the function concept important meaning.
