学习素材是学生解决数学问题、获得数学知识、提高数学能力的基本载体,是学生感受数学与生活的密切联系,体验数学价值,形成正确数学观的重要资源。学习素材的选择不仅影响数学学习的兴趣、动机以及对数学抽象与应用过程的理解,还直接影响学习潜能的发挥。因此,教师应该基于学生的生活经验,遵循学生“最近发展区”的认知规律,努力寻找适合的探究素材。“认识负数”是课程改革以后新引入
Learning material is a basic carrier for students to solve math problems, acquire mathematics knowledge and improve mathematics ability. It is an important resource for students to feel the close connection between mathematics and life, experience the mathematical value and form the correct mathematical view. The choice of learning material not only affects the interest of mathematics learning, motivation and understanding of mathematical abstraction and application process, but also directly affect the learning potential. Therefore, teachers should follow the student ’s life experience and follow the cognitive rules of students “recent development zone ”, and try hard to find suitable inquiry material. “Know the negative ” is the new introduction after the curriculum reform
