Guizhou Province, Middle School Students Math Problems Ability

Posing mathematical problems -the departure point and foundation of initiative in mathematics. Mathematical problems originate from mathematical situations.In mathematics educating and teaching in middle school, the learning chain must be held by eastablishing mathematical situations and posing mathematical problems(situations-problems) and we should strive to develop middle school students' ability of posing mathematical problems ,which will help them bring forth new ideas and improve their practical ability .In the experiment-based study, about 22 experimental classes from 7 middle school in Xing Yi of Guizhou were chosen ,and 739 junior middle school students from 4 middle schools were examined on posing mathematical problems and sieving mathematical problems.The research results show : First,students of experimental classes on both quantity and quality of posing mathematical problems surpassed the contrast classes.Secondly, the quantity and quality of posing mathematical problems of the middle school students and their grades didn't have a positive correlation. Thirdly ,students of co-classes showed marked differences on quantity of posing mathematical problems before and after the experiment ,and quantity after the experiment was higher than that before the experiment .Fourthly,the mathematics examination achievements of the experimental classes were superior to the contrast classes.The basic method of developing middle school students' ability of posing mathematics problem are mainly: 1.carefully establish mathematical situations; 2.take care of students' learner autonomy;cooperative learning; exploratory learning;3.attach importance to teacher's leading actively.
