《数学课程标准》在解决问题方面提出了明确的目标即“形成解决问题的一些基本策略,体验解决问题的策略的多样性,发展实践能力和创新精神。”所以“解决问题策略”的教学在小学阶段非常重要,然而个人认为策略的形成过程更为重要,只有学生在自主探索中形成的解决问题策略才是学生自己的策略、有用的策略。以下结合六年级上册替换策略教学谈几点个人的的几点思考。一、呈现现实性问题,引发探究需要在教学“解决问题策略——替换的策略”时用“曹冲称象”的历史故事引入,从故事中学生知道曹冲是用石头替换大象巧妙的称出了大象的重
“Mathematical Curriculum Standards” put forward a clear goal in solving the problem that “form some basic strategies to solve problems, experience the diversity of strategies to solve problems, develop practical ability and innovative spirit.” “Therefore,” to solve the problem strategy “Teaching is very important in the elementary school. However, individuals think the formation of the strategy is more important. Only the problem-solving strategy that students form in their own exploration is their own strategy and useful strategy. The following combination of sixth grade on the replacement strategy teaching talk a few personal thoughts. First, to present the reality problem, it is necessary to introduce the historical story of ”Cao Chong said“ in the teaching ”solving the problem strategy - the strategy of replacing ". From the story, the students know that Cao Chong is a stone replacement elephant clever The weighing of the elephant
