In the content of courses of mathematics in the junior middleschool, function is a synthesized concept which is combined thealgebra and perform operation with the geometry expound and provewaiting for the basic knowledge. The process of studying functionamong students can be regarded as a over’s hoot of knowingobjective object. This kind of studying is from the research of constantoriginally to the discovery of probing the variable affected. However,many students raised a lot of problems during the study because of thedifferent ways of teaching of their teachers. Thus, there come theserious problems in using functions correctly and applying theknowledge effectively among the students. In order to actually improvethe effect of teaching of function, the author of this thesis has beencarried on a research in a thorough-going way. The author studied thesense of symptom of image to arouse the interests of students inlearning the knowledge and then form the correct concept of functionand property of function in their mind. with the aid of the multimedia.After that, the students can be raised the ability of using the functionand synthesis. Through this studying, teachers can bring up the standardnature of number and audio-visual nature of using shape amongstudents. The author probed and bought the light the law of functionthrough transform to the organic mutually to shape and number withthe combination of the two items in order to raise the ability of thestudents and apply them the view of dialectical materialism observethe object, analyze the problems and solve the ability of problems. |
