随着素质教育的全面实施,中考数学试题发生了明显的变化。只要打开2000年全国各地的中考试题,不难发现,一份份试卷上以解决实际问题为目标的应用题,量大、题活、面宽。一改一卷一题的老模式;二改传统应用题的老面孔;三改考点单一的老内容;四改程式化解题的老思路。可以说,应用问题已成为中考数学试卷中的一道亮丽风景线。数学应用问题,由于联系实际,贴近社会生活和生产,学生普遍感到棘手,甚至望而生畏。畏在哪里?畏在“三关”,即文理关、事理关和数理关。怎样过好“三关”呢?请看下面二例:
With the full implementation of quality education, there have been significant changes in the mathematics questions in the examination. As long as you open the mid-2000 exams across the country, it is not difficult to find that a copy of the test paper is designed to solve practical problems. It has a large number of questions, questions, and breadth. Change the old model of a scroll; change the old face of the traditional application; 3 change the old content of the test site; 4 change the old thinking of the formula. It can be said that the application problem has become a beautiful landscape in the math exam paper. Problems in mathematics applications, due to contact with reality, close to social life and production, students generally feel intractable, and even daunting. Where are fears? Fear in the “three levels”, that is, liberal arts, science, and mathematics. How to have good “three levels”? Please see the following two cases:
