现行苏教版小学数学教材充分体现了“动手实践,自主探索,合作交流”的学习方式,为学生自主学习提供了更为广阔的思维与创造空间,搭建了开发学生智能的实验平台。为此,作为教师要善于挖掘教材资源,把握教材脉搏,拓展教材视野,为优化学生的解题策略勤思考、多探索、下工夫、做文章。一、搭建平台,构建解题策略学生学习数学,不仅是单纯地学习数学知识,更重要的是运用已有知识和经验去探 The current version of the primary version of the textbook of the Jiangsu Education Edition fully embodies the learning mode of “hands-on practice, independent exploration, cooperation and exchange”, provides a broader space for thinking and creation for students ’autonomous learning, and sets up an experimental platform for developing students’ intelligence. To this end, as a teacher should be good at mining resources of teaching materials, grasp the pulse of teaching materials, expand the teaching material field of vision, in order to optimize the students’ problem solving strategies to think hard, explore more, work hard and make a fuss about. First, set up a platform to build problem-solving strategies Students learn mathematics, not only to learn mathematics, more importantly, the use of existing knowledge and experience to explore
