Status And Strategy Of Ability Pupils'mathematics Plausible Reasoning

For a long time, in our mathematics education tradition, educators develop student’s deductive reasoning ability, but ignored the reasonable inference ability training. The plausible reasoning ability research helps to upgrade students thinking, learning, skills, this is undoubtedly conducive to the development of students’ innovative consciousness and creative thinking. So a new curriculum standard has been raised from primary mathematic, which was called "Plausible conclusion". This one emphasize students, not only study from the process of observition, experimenting, operating, concluding, analogy. with the new curriculum reform unceasing advancement, training status of plausible reasoning in mathematics and plausible reasoning ability of the students will become increasingly prominent.Based on the careful of some documents about plausible reasoning, form the view of mathematics education to plausible reasoning for understanding based on the existing knowledge or experience, using the methods of observation, experiment, not completely inductive reasoning, analogical reasoning, intuition and so on, obtain not necessarily the correct conclusion. According to the students the plausible reasoning ability for students based on the description of knowledge or the daily experience, in the context of specific issues, through observation, experiment, analogy, incomplete induction, guess, imagination, intuition thinking process and comparison, drawing, the estimation method of mathematical knowledge, thus put forward the psychological characteristics of personality to guess or conclusion the possibility.Through the interview and classroom observation of the Affiliated Primary School of Shenzhen Middle School of Baoan. From the interview found:Teacher knowledge understanding of plausible reasoning is insufficient and not enough attention, Ways and methods of teachers on the plausible reasoning ability of uncertain and inaccurate, Abstract the plausible reasoning ability training teachers is not wide, deep source material resources, To develop the plausible reasoning ability is a long process, time-consuming and no quantitative standard; From the classroom observation found problems is:Excessive "interpretation of the formation of teaching design" is not conducive to the students the plausible reasoning ability, Teachers do not pay attention to plausible reasoning component of pupils in thinking, The "spoon-feeding" into the "ask" serious squeeze the students thinking time reasoning, To glance over things hurriedly, not deep understanding and application of plausible reasoning, Mechanical imitation, lack of reasonable inference value experience, Incomplete "reasonable inference plausible", embodies the essential lack of plausible reasoning.The reason for this situation mainly include:Teachers are lack of relevant theoretical knowledge of plausible reasoning is the insufficient internal sensible reasoning ability, The teacher’s attitude is not correct is insufficient external sensible reasoning ability, The realistic contradiction knowledge is more important than ability hinders the reasonable inference ability training process, Failure to correct positioning and understanding of elementary mathematics discipline characteristic, Primary school mathematics plausible reasoning teaching has been ignored in primary school mathematics classroom teaching. Improvement strategies of cultivating primary students’mathematics reasoning ability are the main:To strengthen the theoretical level of teachers, change the teaching idea, Culture penetration of plausible reasoning ability in the teaching of mathematics in four plate, channel widening training, Create a set of suitable for training students in the plausible reasoning ability of practice mode, Step-by-step process, step by step the plausible reasoning ability.
