Primary And High Cohesion Function Teaching Research

Function is secondary math core content, it has always beenthroughout secondary school teaching, its ideas and methods includealgebra, equations, inequalities, limit the number of columns, geometryand other mathematical field, it is good to develop students’ ability tothink logically and dialectical concepts material. Functions section hasbeen important and difficult for high school teaching, the hot spots ofCET, over the years, the title of the finale in CET are the functional form,to examine derivative flexible application or combined with inequality, sothis part of knowledge are throughout high school mathematicsteaching. But I found these years students for this part of the mastery ofknowledge is not satisfying, or even getting worse, the main reason isthat the beginning of high school teaching disjointed work did not do agood job of teaching convergence. The purpose of this part is to identifythe similarities and differences of the function of teaching between highschool and junior school, to look for a connecting link, so that studentsget rid of the function the fear, really appreciate the function of ideology.The purpose of this paper:1. History of the development of theconcept of function;2. Secondary function classification;3. Functionsand equations of contact with distinction;4. Functions and Inequality;function application;6. the distinction and Contact in junior and seniorhigh function. Discussed the type of the function of the middle and highschool learning, teaching objectives, defined, find out the similarities anddifferences in teaching methods, learning methods and materials, andpointed out that the early high school teaching efforts should converge on,especially an early the beginning stages of teaching and teachingmethods. The article also highlights a secondary function as a junior highand high transition bridge carrier, in order to identify the beginning ofhigh school convergence. In the article, the author uses the questionnairemethod to show students learning difficulties; article also uses a caseanalysis, pointed out that the different requirements of the function part, and then pointed out some good ways for students: teachers, studentsprepare in advance, learn the guidance, corrected; refresher; mentalattitude adjustment; using a variety of teaching methods. Meanwhile,pointed out that the existing uncertain task of teaching so as to cause ofthe majority of the attention of educators and research.
