小学数学教学强调的是学生对数学知识的自主学习,“先学卡”是学生进行“先学”的有效载体,教师要基于《数学课程标准》的基本理念及基本要求,优化“先学卡”的设计。要基于生活经验,设计尝试性先学卡;基于学习难点,设计操作性先学卡;基于数学思维,设计探究性先学卡。
Primary mathematics teaching emphasizes students’ autonomous learning of mathematics knowledge, “learning card ” is an effective carrier for students “learning ”, teachers should be based on the basic concepts and basic requirements of “mathematics curriculum standards”, optimize “First card ” design. Based on the experience of life, try to design a probationary card; based on the learning difficulties, the design of the operation of the first card; based on mathematical thinking, design inquiry card.
