The function and the function thought are to run through a entire mathematic high school mainline, one of the important content being middle school mathematical education. The function is a mathematic important basic concept of high school , it permeates in every mathematics part content, be always the college entrance examination hot spot , priority content. The function thought , the viewpoint being to use motion to change, the relation analysing and studying quantity in concrete problem , the knowledge building function relation , wielding a function's, problem gets a messenger solve. This mentality lies in the intrinsic characteristics revealing the problem quantity relation , the development duplicating each other in the variable to problem studies, the motion from the variable changes, the angle broadens connection and development solving problems train of thought. Function thought is to use motion , change , to contact , to come analyse corresponding viewpoint the thought that quantity concerns in the mathematics and the real life. Function thought culture is that high school mathematical education trains one in target important content. The main body of a book is complied with discussing function concept teaching starting , is lay stress on the process taking "basis" as starting point , attaching importance to teaching , is pay attention to conclusion occurrence , development and revealing applying process's and is understand that specially, have emphasized that thought depth culture is to take solid ABC and basic skills as premise. The main body of a book be hit by every chapters and sections teaching and college entrance examination to the function combining with teaching material examine, having discussed function thought is function basic theory distillation , is that the thought revealing function consciousness method essence and law develops crystal. In teaching, the teacher should make a student be confined to only the simple field simulation , a series of skills and trick in wushu , etc. not only in solving problems in process , be the circumstances creating a self go and observing , probing , studying problem but more much. Reasonable method rises on the basis cleaning up a train of thought , being engaged in clear principle, with concrete pattern with solving problems to certain thought altitude. Such ability makes student's thought develop and deepen really , make mathematics educational quality get real rise, culture realizing function thought then. That the speciality discusses the main body of a book and the culture not having realized to the function additionally, is to fuse in each links discussion but , having embodied mathematics mentality and concrete mathematics knowledge is that the organic entirety , their mutual connection, are interdependent , cooperate and develop.
