“创新是一个民族进步的灵魂,是一个国家兴旺发达的不竭动力。一个没有创新能力的民族,难以屹立于世界先进民族之林。”教育是知识创新、传播和应用的主要基地,也是培育创新精神和创新人才的摇篮。结合近年来的教学实践,从宽松的氛围、兴趣为前提、质疑变求异、参与作途径等四个方面阐述了在数学教学中如何迸发出创新的火花。 “Innovation is the soul of a nation’s progress and an inexhaustible motive force for a country’s prosperity and development. A nation without innovative capabilities can hardly stand in the forefront of the advanced nations in the world.” Education is the main base for knowledge innovation, dissemination and application. It is also the cradle of cultivating innovative spirit and innovating talents. Combining with the teaching practice in recent years, this article expounds how to spark innovation in mathematics teaching from the aspects of relaxed atmosphere, interest as the prerequisite, questioning the variation and the way of participation.
