学习材料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密切联系,体验数学价值,形成正确数学观的重要资源。教学中,组织不同的学习材料或对相同材料的不同组织,会使学生经历截然不同的学习过程。学习材料的选择和使用决定着学生对数学学习的兴趣和对数学知识的理解程度。实践表明:通过教师精心设计,形式简单、操作方便的小材料也能在课堂上发挥大作用。
Learning material is a basic carrier for students to solve math problems, acquire math knowledge and improve mathematics ability. It is an important resource for students to feel the close connection between math and life, experience the value of math, and form a correct mathematical view. Teaching, the organization of different learning materials or different organizations of the same material, will enable students to experience a very different learning process. The selection and use of learning materials determine the student’s interest in math and understanding of math. Practice shows that: through the careful design of teachers, the form of simple, easy to operate small materials can also play a big role in the classroom.
