法。我还观察到学生错把12＋32 当作112＋32输入计算器，对算出的明显错误的答案连眼都不眨一下。毕竟，他们用的是计算器，所以，一定没错。 10
Educators also claim that calculators are so inexpensive and commonplace that students must
become competent in using them. New math texts contain whole sections on solving problems with a calculator. Most people, including young children, can learn its basic functions in about five minutes. Calculators do have their place in the world outside school and, to a limited extent, in higher-level math classes, but they are hardly education tools.
教育家们还声称，计算器如此便宜而又普遍，学生必须学会熟练使用。新的数学教材有整节整节关于用计算器解题的内容。大多数人，包括年幼的孩子们，用大约五分钟就能掌握计算器的基本功能。计算器在学校之外的社会中的确有其地位，在高等数学课堂上也有一定的作用，但它们很难算得上是教育工具。 11
