1Context of the creation of middle school math problem1. Definition of mathematical problem situations “Situation”, “> interpreted as:” When a person carrying out an action in which the social environment. Is that people have the specific conditions of social behavior. “Specific to mathematics teaching, mathematical problem situation, is that students activities during the learning of mathematics in which the learning environment. Mr. Wang Bingyi, Mr. Yang Xiaobin that: “Mathematics is a situational awareness inspire students to question the data values of the stimulus material and background information. is engaged in mathematical activities, the environment, produce the conditions for mathematical behavior. “ <> the “situation” is divided into three categories: “real situation, that people around the existence of other people or groups, to imagine the situation, means the person or group consciousness, the two sides interact through various intermediary carriers , implicit context, means a person or group behavior is included in a symbolic meaning. “in the field of 2mathematics teaching, Professor Sun Xiaotian said: mathematical problem situation should satisfy two: one is concerned with the student life experience, suitable for Mathematics Curriculum and the interface between the student experience, the other is to be made by the students of Applied Mathematics and innovation, discovery of the carrier. in accordance with this principle into the problem situation he: realistic, ultra-realistic (virtual, knowledge base and experience of students the existing three categories. Thus, the problem situation which does not necessarily have to be some truth real life, sometimes situations can be very abstract. Dr. Xia Xiaogang said: With the continuous development of students and school physical mathematical content the increasing abstraction, the creation of mathematical situations teachers may be more based on the mathematics within their own, focusing on the linkages with other disciplines. can be seen, mathematical problem situation is not just the students real life situations, can be virtual, can also be a knowledge of mathematics. 2. Mathematics psychological basis of problem 3situations Psychology, the student’s cognitive structure is the fundamental condition for transfer of learning. Students in the study of the phenomenon of widespread migration, if the teacher in the teaching of the creation of appropriate migration scenario, you can promote positive transfer of learning to enable students to consciously use of existing knowledge, to assimilate new knowledge continuously, so as to achieve adjustment, expansion and optimization of existing cognitive structure, the establishment of the cognitive structure of a new purpose. According to cognitive theory, mathematics classroom teaching process should be to continue to ask questions and problem-solving approach to issues of access to new knowledge and thinking process. To solve the problem first raised the issue, the famous mathematician Hua said: “The difficulties With the formula is not to prove, but before that there is no formula for how to find the formula. “Therefore, teachers are both in the whole process of mathematics teaching, or in one part of the teaching process, should attach great importance to mathematical problem situations the creation. 4Because of this, clear that the new curriculum standards: Teaching secondary school mathematics teaching should be combined with the specific content of a “problem situation - modeling - the interpretation, application and development” model to start, in which the problem situation first, obviously requiring teachers to explore issues and create a positive context, leading students to explore the issues in the activation process knowledge to help students interact with the world based on their unique experience to construct their own knowledge, to create new knowledge for the students to find an optimal psychological environment and understanding of the ideal of knowledge ladder. 3. Mathematical problem requires the creation of situations Both concerned with “social”, but also based on “students” and as an educational task of Mathematics, a public foundation in mathematics, certainly carries the value of education. <
