一、多媒体创设的情境,能激发学生的创新思维《数学课程标准》提出：“让学生在生动具体的情境中学习数学”、“让学生在现实情境中体验和理解数学”．数学家华罗庚也说过：“人们早对数学产生了枯燥乏味、神秘难懂的影响。成因之一便是脱离实际．”创设情境有利于激发学生学习数学的兴趣和求知欲望；有利于学生体验和理解数学,感受数学的力量．
I. Situations created by multimedia can inspire students’ creative thinking. The “Mathematics Curriculum Standards” proposes: “Let students learn mathematics in vivid and concrete situations” and “Let students experience and understand mathematics in real situations”. The mathematician Hua Luogeng also said: “People have long had a boring and mysterious influence on mathematics. One of the causes is divorced from reality.” Creating a situation is conducive to stimulating students’ interest in learning mathematics and the desire for knowledge; it is conducive to student experience. And understand mathematics, feel the power of mathematics.
