The Problem Research In The Function Teaching Of The High School

The function is the core contents of the high school mathematics. The study of the function, symbolize from often measure mathematics study to start enter to change to measure the mathematics study. The comprehension function requests the student to set up a process in the thinking, a situation that the reflection function may appear.( The analyze the type, the form or portraits to mean) the junior high school teaching material in the standpoint of the sport variety carries on the definition to the function, reflecting the people in history to one of its understanding, and this definition compare in order to keep the view, be easy to accept, but, because this define and did not announce to public the essence of a function concept completely, in the stage of the senior high school that regards the function as the important contents, the lesson defines function as originally two that gathers a kind of reflect to shoot, make us have more deep understanding of a layer to the function concept thus. Because the function concept is more abstract difficult in were comprehend by the student, result in student at the study function property such as: The definition area, the value area, monotone of the function, strange accidentally sex, periodic etc. is in the problem, always at a loss what to do, is this, this text mainly discussed under the construction or purchase doctrine of the basic mode of mathematics concept teaching, the real connotation that is "comprehend" or "digest" mathematics knowledge to student did lately hermeneutic, and took this as the theories to put forward mathematics concept teaching strategy, put forward personal views for the actual teaching.
