【摘要】：新课改明确提出让学生通过数学建模来解决实际问题。目前关于中学数学建模的研究,主要的研究对象是高中数学建模教学。在我国,研究初中数学建模教学的文章在中小学教育的相关文章中占比不到1%。由于缺少有效的教学方法和学习方法导致在初中开展数学建模教学还处于未成熟阶段,因此研究初中数学建模教学策略具有重要意义。本文阐述了数学建模的思想内涵、建模教学的一般步骤、设计原则。以烟台青华中学和烟台五中93名学生为调查对象,通过设计调查问卷调查和试题测试,调查初中生建模能力现状以及教师数学建模实施情况。根据调查数据,分析了存在的问题和不足,并针对不足分析了问题存在的原因。针对数学建模教与学中存在的实际问题,提出以下教学策略:(1)由简入难、循序渐进、树立信心;(2)抓住重点,寻找关键,转化问题;(3)模型归类,把握建模方向;(4)教师应不断增加知识储备,深入理解建模思想内涵;(5)引导学生“从做中学”;(6)改变对学生的评价方式,由单一地对结果评价转变为注重对学生思维过程的评价。根据提出的教学策略,选择典型教学环节进行教学设计,有针对性地落实了数学建模教学策略,通过课后的分析和调查发现该教学设计取得了良好的教学效果,为广大一线教师进行建模教学提供了有益借鉴和参考。
[Abstract]:The new curriculum reform put forward to allow students to solve practical problems through mathematical modeling. The current research on mathematical modeling in middle school, the main object of study is the mathematical modeling teaching in senior high school. In China, the research on junior middle school mathematics modeling teaching in the primary and secondary education accounted for less than 1%. due to the lack of teaching methods and learning methods the result is still in an immature stage to carry out mathematical modeling teaching in junior high school, so the study of teaching strategies of junior middle school mathematics modeling has important significance. This paper expounds the connotation of the idea of mathematical modeling, the general step of the modeling teaching of the design principle. In Yantai Qinghua middle school and Yantai fifth 93 students as the research object, through a questionnaire survey and test and investigation of junior high school students and teachers' mathematical modeling ability of modeling and implementation. According to the survey data, analyzes the existing problems and shortcomings, And analyzes the reason for insufficient. In view of the actual problems of mathematical modeling in the teaching and learning of existence, put forward the following strategies: (1) from simple to difficult, step by step, set up confidence; (2) to seize the key, find the key, the transformation problem; (3) the model classification, grasp the direction of the modeling; (4) teachers should continuously increase the stock of knowledge, understanding the modeling thought connotation; (5) to guide students "learning by doing"; (6) the change of student evaluation methods, evaluation results from a single change to focus on the evaluation of students' thinking process. According to the proposed teaching strategies, choose the typical teaching link of teaching design, targeted implementation of the mathematical modeling teaching strategy, through the investigation and analysis found that the class teaching design has achieved good teaching results provide a useful reference for teachers teaching model.
