“材料引起学习,材料引起活动”。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的联系、体验数学价值的重要资源。教学中,组织不同的材料或对相同的材料的不同组织,学生经历学习的过程就截然不同,学习材料的选择与使用往往会影响学生对数学知识的理解和数学能力的形成。选择学习材料时,有时可以采用“统一”的方式,即“学生集体用相同材料学习、探究”;有时也可以采用“自选”的方式,即“学生个体用不同材料进行学习、探究”。教学中,是“统一”
“Materials cause learning, materials cause activity ”. Learning material is a basic carrier for students to solve math problems, acquire mathematics knowledge and improve their math ability. It is an important resource for students to experience the connection between math and life and experience the value of mathematics. Teaching, the organization of different materials or different organizations for the same material, students experience the learning process is very different, the choice and use of learning materials often affect students’ understanding of mathematical knowledge and the formation of mathematical ability. When selecting learning materials, sometimes it is possible to adopt a “uniform” way, that is, “students collectively use the same materials to study and explore”, and sometimes they can adopt “self-selection”, that is, “students use different materials To learn, explore ”. Teaching, is “unity ”
