1、小学数学教学案例分析与反思让学生(含个体和群体)在课堂中“活”起来。要使小学生在数学课堂中“活”起来,小学数学教学应结合小学生的认知发展水平和已有的知识经验展开,为学生提供充分从事数学活动的机会,帮助他们在自主探索和合作交流的过程中真正理解和掌握基本的数学知识与技能、数学思想和方法,获得广泛的数学活动经验,让课堂数学“活”起来,即让学生(含个体和群体)在课堂中“活”起来。要使小学生在数学课堂中“活”起来,不妨从以下方面做起:一、将生活融入数学,让学生体味数学乐趣。实践表明,通过寻找与学生生活相关的实例,有目的地将生活中的数学
2、问题提炼出来,再将数学知识回归生活,既能让学生感受生活化的数学,用数学眼光看待周围的生活,增强学生生活中的数学意识,又有利于发掘每个学生自主学习的潜能,这无疑是提高学生学习数学积极性的“活力源泉”daysofDrudge,illnessincreased,heChongsoonFattsaid:"itseemsthatI'mnotdeadtoJapansoldierstorturedtodeath,anditcertainlycannotgohomealive,evenwithsmallJapanfightandgetito

8、、把生活实例融入数学教学。从学生已有的生活经验和知识背景出发创设问题情境,开放小教室,把生活中的鲜活题材引入数学学习的大课堂。既要让学生感受到所面临的问题是熟悉的、常见的,同时又是新奇的、富有挑战性的。一方面使学生有可能去进行思考和探索,另一方面又要使其感受到自身已有的局限性,从而处于一种
