Reasoning to explore the use of high school mathematics problem-solving ideas
Abstract : In recent years, China's mathematics curriculum reform gradually in depth at the development of plausible reasoning is to develop innovative capacity of reasoning, extensive penetration of the various modules in the teaching of high school mathematics content. In 2003, China's Ministry of Education promulgated the "high school mathematics curriculum standards (experimental)" Reasoning for the first time the introduction of high school mathematics curriculum, a "reasoning and proof," subject, clearly stated that "the development of sensible reasoning ability of students . " Existing studies have shown that, despite the mathematical problem-solving in the theoretical basis of plausible reasoning has been maturing, but the use of reasonable inference to explore ideas of high school mathematics problem-solving and scientific research is Lueqian system. In this paper, the theoretical basis of plausible reasoning were reviewed, summarized, including the basic conceptual framework and support the theory, on this basis, through qualitative analysis, Analysis of a mathematical problem-solving and Reasoning intrinsic association between: Help promote understanding of the conditions of math problem solving capabilities and independence, that the mathematical problem-solving in induction, analogy, think of the meaning and application of such methods. Then, several specific cases of this detailed analysis to clarify how to guide students to explore the rational use of plausible reasoning, problem-solving ideas found in the further consideration based on the reasonable inference to explore the use of general rules to problem-solving ideas summarized. Finally, for the use of plausible reasoning, broaden their problem-solving ideas, this paper presents a number of countermeasures and suggestions, including raising the literacy teacher's sensible reasoning, attention to the students experience the real process of mathematical activity, etc.
Keywords: mathematical problem-solving, Reasoning, explore ideas, case studies

Using the ratiocination explore high school mathematics problem-solving ideas in recent years, our country to pick the mathematics curriculum reform is to ZongShenChu development, to develop students' innovative ability ratiocination is the reasoning process, extensive penetration in the high school mathematics each module of the teaching content. In 2003, China's ministry of education issued "ordinary high school mathematics curriculum standard (experiment the first time), into the high school mathematics course ratiocination, appear" reasoning and proof "project, definitely put forward" to develop the students' ability of ratiocination ". Current research shows that, although the mathematics problem-solving in the theoretical foundation of the ratiocination discussion has become increasingly perfect, but about using the ratiocination explore high school mathematics problem-solving ideas for the research is slightly less systematic and scientific. In this paper, first ratiocination theory base
