1.抽象。对于学科来说,抽象是数学的首要特征,抽象为推理提供了对象,抽象了,才可能广泛应用。“两种事物,如果有相同的量或形,便可用相同的数学方法,因而数学必然、也必须是抽象的。”对于育人来讲,“数学虽不研究事物的质,但任一事物必有量和形,所以数学是无处不在、无时不用的”。“因而,学生经历数学的抽象,不仅由此生成了数学的研究内容,更具普遍意义的是抽象的过程,能 Abstraction For subjects, abstraction is the primary feature of mathematics, abstraction provides the object for reasoning, abstraction, it may be widely used. ”Both things, if the same amount or shape, can be used the same mathematical method, and therefore mathematics must and must be abstract. “ For educators, ”Although mathematics does not study the quality of things, but Anything must be quantity and shape, so mathematics is ubiquitous, all the time “. ”Therefore, students experience mathematics abstraction, not only from the mathematical content of the study, the more general is the abstract process, can
