【摘要】：模型思想的建立是学生体会和理解数学与外部世界联系的基本途径,本文根据Blum和Niss提出的七阶段建模循环,用三个数学化难度不同的建模测试任务对中国八个代表省市的1172名八年级学生进行大规模测试。测试结果表明,我国八年级学生在再现层次的数学建模表现良好,能熟练识别常见的标准模型;在联系层次的数学建模存在欠缺,难以将现实情境转化为数学模型;在反思层次的数学建模难以理清各种要素、关系和构建恰当的模型。反思了我们脱离现实的纯数学训练和伪建模训练,建议加强现实情境到数学模型的"数学化"训练。
[Abstract]:The idea of modeling is the basic way for students to understand the relationship between mathematics and the outside world. According to the seven-stage modeling cycle proposed by Blum and Niss. A large scale test was conducted on 1172 eighth grade students in eight provinces and cities in China with three modeling tasks with different mathematical difficulties. The eighth grade students in our country perform well in the mathematical modeling at the reproduction level and can recognize the common standard models skillfully. It is difficult to transform the real situation into the mathematical model because of the lack of mathematical modeling at the connection level. Mathematical modeling at the reflective level is difficult to clarify the various elements, relationships and build the appropriate model. We reflect on our training in pure mathematics and pseudo-modeling, which is divorced from reality. It is suggested to strengthen the "mathematical" training from the real situation to the mathematical model.
