数学习题教学中,研究习题的引伸与应用,拓宽学生的思维空间,发挥习题的智能训练价值,特别是学生创新思维和实践能力的培养,必须引起我们数学教师的足够重视。 一、由例及类,异中求同 法国数学家笛卡尔曾说:“我所解决的每一个问题都将成为一个模式,以用于解决其它问题。”有些习题的作用便是如此。如初中《代数》课本第三册,解方程组:两个未知数的和与积都是常数,我们不妨称这类方程组
In mathematics problem teaching, it is necessary to study the extension and application of exercises to broaden students 'thinking space and develop the value of intelligent training of exercises, especially students' innovative thinking and practical ability, which must be paid enough attention to by our maths teachers. First, from case to case, from different genres The French mathematician Descartes once said: “Each of the problems I solve will serve as a model for solving other problems.” This is the case for some exercises. Such as junior high school “algebra” textbook third, solve equations: two unknowns and products are constant, we may wish to call such equations
