著名数学教育家弗赖登塔尔指出:“学生应该再创造数学化而不是数学,抽象化而不是抽象,图式化而不是图式,形式化而不是形式,算法化而不是算法,用语言描述而不是语言……”我们可以理解为,在指导学生数学学习的过程中,教师应该把着眼点放在学习活动的过程而非结果上,要让学生主动经历各种“化”的过程,在这个“化”的过程中自主地建构起图式、 The famous mathematics educator Freudenthal pointed out: “Students should recreate mathematics instead of mathematics, abstract rather than abstract, schema instead of schema, formal rather than formal, algorithmic rather than algorithmic, Language description rather than language ... ”We can understand that in guiding students in the process of mathematical learning, teachers should focus on learning activities rather than the outcome of the process, let students take the initiative to experience a variety of “The process, in this ” process "process autonomously construct the schema,
