The Analysis Of The Construction Activity In The Command Of Mathematics Concept And The Teaching Design

Mathematics is the necessary tool in the people' life, work and learning. Mathematics reasoning, judging and proving is carried through according to mathematics concept. Mathematics concept is the foundation of mathematics theorem, principle formula. So mathematics concept is chief in mathematics. In the past few years, constructivist is introduced into mathematics. Investigators have always accepted at large that the learning of mathematics concept must establish the relation among concepts, which is finished by the construction activity.At first, the headstream of construction is searched in theory. And the possibility off construction in the command of mathematics concept in the classroom is discussed, by analyzing the internal structure of the mathematics concept. Then this text analyzed from two aspects how to proceed the construction of the mathematics concept: construction of the double direction and construction from concrete to abstract to concrete. And the thesis discuss the teaching method adapting to construction of concept in the classroom-variation type of teaching and the whole teaching; Finally the thesis bring forward that material of sensibility is offered, difference of students is regarded and cognitive conflict is inspired in the learning of mathematics concept.In the textual appendix, there is the analysis of a section teaching case, in order to try to explain further how to carry through the construction of the mathematics concept in the teaching.
