把现实世界中的实际问题加以提炼,抽象为数学模型,求出模型的解,验证模型的合理性,并用该数学模型所提供的解答来解释现实问题,我们把这一数学知识的应用过程称为数学建模。近几年,各地的中考数学试题中加强了应用题的考察,这些应用题大多以数学建模为中心,考察学生应用数学的能力。翻开每年的试卷分析,我们不难发现应用题的得分率远远底于其他试题,不少学生的数学建模能力和应用数学意识缺失严重。因此,明确数学建模教学的重要性,加强初中数学建模教学,显得格外迫切。
The practical problems in the real world are refined, abstracted as a mathematical model, the solution of the model is obtained, the rationality of the model is verified, and the practical problems are solved by the solutions provided by the mathematical model. We call this process of application of mathematical knowledge Mathematical modeling. In recent years, around the entrance exam math test questions to strengthen the application of these questions are mostly mathematical modeling as the center, examine the ability of students to apply mathematics. Open the papers analysis each year, we can easily find the application of the score at the end far away from other test questions, many students mathematical modeling abilities and lack of awareness of the application of mathematics serious. Therefore, to clarify the importance of mathematical modeling teaching, strengthening junior high school mathematical modeling teaching, it is particularly urgent.
