培养初中生初步数学建模能力的调查研究 ——以贵港市中心区某中学为例 数学与应用数学 李金婵 [摘 要] 数学的基本特征是应用的广泛性，生产和科学技术的不断发展，应用数学的地位逐步上升，数学数学建模成了数学和科学工作者面临的重要课题。义务教育课程标准将数学建模思想渗透到代数式、方程、不等式、函数等方面的教学中，因此开展数学建模教学成为当今数学教育改革的热点之一。由于各种原因，初中学生的数学建模能力很差，如何合理有效地实施数学建模教学是许多初中数学教师感到困惑的一大难题。因此，在初中开展数学建模能力的调查具有重要意义 本文通过调查法，研究初中生初步数学建模的能力及影响因素。在研究中通过测试和访谈了解初中学生数学建模能力的现状,得出初中学生数学建模能力普遍偏低。造成初中学生数学建模障的主要原因有：心理因素；数学抽象能力较弱；新课程改革后教师角色的转换问题；教师对学生的评价方式。针对存在的问题，本文提出一些策略，希望在培养初中生数学建模能力方面为教师提供一些参考。 [关键词] 初中生；数学建模；能力；培养 Develop preliminary mathematical modeling ability of investigation and study in junior high school students ——A high school in guigang city central district as an example Mathematics and mathematics LI Ji-chan Abstract： The application of mathematics is the basic characteristics of universality, the production and the continuous development of science and technology, the status of the applied mathematics gradually rise, mathematical mathematical modeling has become an important task to math and science worker. Compulsory education curriculum standard to penetrate mathematical modeling thought into algebraic expression, equations, inequalities, functions in the aspects of teaching, therefore to develop mathematical modeling teaching become a hot topic in todays mathematics education reform. Due to various reasons, the junior middle school students ability of mathematical modeling is very poor, how to reasonably and effectively carry out mathematical modeling teaching is a big problem to many junior middle school mathematics teachers feel puzzled. Therefore, in the junior middle school mathematics modeling ability of investigation is of great significance. In this paper, through investigation, the preliminary ability of mathematical modeling and influencing factors of junior middle school students. In the study, by testing and interviews to understand the current situation of junior middle school students ability of mathematical modeling, it is concluded that the junior middle school students ability of mathemat
