1987年,弗赖登塔尔到中国访问,他在华东师范大学数学系演讲,走上讲台的第一句话就说:“在荷兰,中学教室里的桌椅摆法都是围成一圈,教师在学生中间活动,如果有一个学校的教室像今天这样:前面一张讲台,下面是一排排桌椅,那么这所中学的校长大概要被撤职了!”教室里发出一阵笑声,同时也引起人们的思索。这一年,弗赖登塔尔82岁。时至今日,“学习数学唯一正确方法是实行‘再创造’”还是大家耳熟能详的理论名言和特别青睐的理论依 In 1987, Freidenhalt paid a visit to China. He gave a speech in the Mathematics Department of East China Normal University and said in the first sentence of the podium: “In the Netherlands, Circle, teachers in the middle of the activities of students, if there is a school classroom like today: a podium in front, the following is a row of tables and chairs, then the high school principal probably be dismissed! ”A laugh in the classroom Sound, but also arouse people’s thinking. This year, Freudenthal is 82 years old. Today, “the only correct way to learn math is to practice re-creation.” It is also a well-known theory and a very popular theory
