数学运算能力是高中数学重要能力之一,运算能力的强弱是关系到数学学习成绩的一个重要因素。一般地说,随着学生年段的不断升高,学生的运算能力也应该不断提高,可是在教学实践当中,却常常看到另外一种情形:相当一部分的高中生(包括各种层次的)运算能力出现了停滞甚至“退化”的现象,以前所练就的一些数学基本功不但没有提高,反而有减弱的趋势。
Mathematical computing ability is one of the important ability of high school mathematics, the strength of computing power is an important factor related to the achievement of mathematics. Generally speaking, with the continuous increase of students ’years, students’ computing abilities should also be continuously improved. However, in the teaching practice, another situation is often seen: a considerable number of high school students (including all levels) The ability of computing has stagnated or even degenerated. Some of the basic math exercises that have been practiced in the past have not only failed to improve, but have weakened trends.
