Experiment Research Of Junior High School Mathematics Opening Question Teaching Strategy

In the new reform of Chinese education ,the phenomena should be changed Whichmeans that knowledge teaching is only treasured,but the abilities that students get knowledgeindependently are neglected which lead to the overload of students' learing ,students'narrowknowledge ,lack of creative ideas ,and single structure of abilities.In order to alter the currentinstruction situations,based on the pproach of opening-ended problems,we conduct theexperiment on the research into teaching methods and approachs.In this paper ,four strategiesof class teaching are investigatedBased on the theoretical discussion:The first strategy :Development is made throughcooperative learning and producing questions.Inherent relations of knowledge are reproducedthrough experiencing finding out ,exploring and discussing .The idea that students'development is essential ,is reflected through finding out changing factors according tostudying invariable factors.The second strategy :Establish the cognitive structure with theknown knowledge by imagination and analogy.Conclusions are acquird by studyingconditions or by studying results.The third strategy : analogy. And then solve new problemsunder the new constution;Find out new methods and from new concepts. Extend the conceptsby the oflooking for different n ew thoughts.The fourth strategy :The solvemeant ofpractical problems is studied through creating circumstances and building models.We also discuss the operat ablitity of the strategy the practical teaching cases.Thisexperiment also can improve mathematic grades in a large scale, generate aPositive transfer for other motivate their learing interests and consummate their learningmethods obviously relieve their burden ,students' subjects,so as to obviously relieve theirburden.
