Construction Of Middle School Mathematics In The 'concept Of Introducing The Concept Of The Study

Mathematics concept is the basic point of mathematics content, the start point of lending theorem or rule, and the key point of setting up the theory system. Meanwhile it is the foundation of students' cognition and mathematics thinking. Therefore concept plays an important role in teaching and leaning of mathematics. However, in our daily teaching, the ignorance of concept teaching, which is regarded as teaching definition of the concept has contained the improvement of students' abilities of mathematics thinking greatly. So we should pay close attention not only to the result but also to the course.The concept introducing is a kind of course to creat a situation of leaning, which make students get the essential attribute of the concept through analysing, comparing, synthesizing and abstracting. Based on the doctrine of constructing, the article is discussing how to found the question effectively in classroom instruction, make students turn into the concept independently, and propose the introducing methods, such as the direct introduce, the interesting introduce, the comparative introduce, the experimental introduce and so on. Though breakthrough points are different for these methods, they are all on the basis of constructivism, which must be under the guidance of the principles such as the recreating principle, the principle of zones of proximal development, the situational principle, the emotional principle etc. As a teacher, you should put up a platform obtaining the concept voluntarily for students by some useful strategy such as the strategy of advance organizer, the strategy of question, the ocular strategy etc.
