课改以来,我们的数学课堂一度出现了“乱花渐欲迷人眼”的景象。也许是为了一改以前“老旧、死板”的课堂面孔,教师们使尽浑身解数,将各种新鲜有趣的元素引进课堂。例如,越来越富有童趣的教学情境,越来越活泼的实践活动等。乍一看,课堂“趣”了、“活”了,生活味更浓了,但细细一品,数学味被冲淡了,数学本质渐渐被忽略,这不得不引起我们的警醒和反思。如何在葆有生动、有趣的课堂氛围的同时,更加凸显数学本质,呼唤“数 Since the curriculum reform, our math class once appeared ”chaotic flower eyes“. Perhaps it is to change the classroom face of ”old, rigid," and teachers are trying their best to introduce all kinds of fresh and interesting elements into the classroom. For example, more and more childlike teaching situations, more and more lively practices. At first glance, the classroom is more interesting, but life is more concentrated. However, the delicate taste and the mathematic taste have been diluted and the nature of mathematics has gradually been neglected. This has caused us to wake up and Reflection. How to highlight the essence of mathematics while holding a vivid and interesting classroom atmosphere?
