所谓数学建模,就是把现实生活中的实际问题加以提炼、抽象、概括,用数学语言表述出数学模型,再用数学模型去解释或解决一些实际问题。通俗地讲,数学模型就好比一把钥匙,照理说,学生拿着这把“钥匙”就可以把同类型的“问题之门”给打开。然而,实际教学中,学生拿着“模型之钥”去“开门”时,却并非个个顺利,也并非每次都成功,其间遇到的障碍值得重视和反思。障碍一:习惯于机械套用模型,时现“刻舟求剑”
The so-called mathematical modeling refers to the actual problems in real life to be refined, abstracted, summed up in mathematical language to express the mathematical model, and then use mathematical models to explain or solve some practical problems. To put it in a nutshell, a mathematical model is like a key, and it stands to reason that a student holding the key can open the same type of problem door. However, in actual teaching, when students hold the key of “model” to “open the door”, they are not all successful and not always successful. The obstacles encountered in the teaching process deserve attention and reflection. Obstacle 1: accustomed to the mechanical application of the model, now “carved sword ”
