华罗庚先生曾指出:“数缺形时少直觉,形缺数时难入微,数形结合百般好,隔裂分家万事非.”在中职数学教学中,数形结合思想有其独特的重要意义.尤其是中职学生普遍存在基础差、底子薄的现象,通过把代数上的“数”(代数式或变量之间的数量关系)与几何上的“形”(曲线或区域)结合起来,可以让学生通过一些具体的、直观的图形提高学生的感性认识,更好地认识问题、理解问题,是圆满完成中职学校基础课数学教 Mr. Hua Luogeng once pointed out: “When the number of lack of shape less intuition, the lack of shape when the number of micro-intolerable, with a combination of all sorts of good, separated from home all sorts of things. ” Mathematics teaching in mathematics, , Especially the phenomenon that the students in vocational schools have the basic difference and the weak foundation. By comparing the number of algebraic (algebraic or quantitative relationship between variables) with the geometrical Or area) can allow students to improve students’ perceptual awareness through a number of specific and intuitive graphics to better understand the problem and understand the problem is the successful completion of the basic mathematics teaching in secondary vocational schools
