教学中适当介绍经典的一题多解案例,可以激发学生发现和创造的强烈欲望,训练学生对数学思想方法的娴熟运用,锻炼学生思维的广阔性、深刻性、灵活性和发散性,发展学生创造性思维.下面介绍一道经典案例,供大家赏析.一、问题的提出有这样一道中考题:试题(江苏泰州)如图1,在平面直角坐标系中,直线y=x-2与y轴相交于点A,与反比例函数在第一象限内的图象相交于点B(m,2). Proper introduction of the classical case-based solutions in teaching can stimulate the students’ strong desire to find and create, train their students’ skilful use of mathematical thinking and methods, develop the broad, profound, flexible and divergent thinking of students, and develop students’ Creative thinking. Here is a classic case for everyone to appreciate. First, the question raised There is such a test questions: Test questions (Taizhou, Jiangsu) Figure 1, in a rectangular plane coordinate system, the line y = x-2 and y At point A, the image in the first quadrant intersects the point B (m, 2) with the inverse function.
