在日常教学中,就我们多数老师来看,支持学生利用计算器的并不多,认为学生利用计算器会带来许多负面影响:如利用计算器,会使学生的计算能力退化,根式化简能力丧失,一元二次方程求解失去意义,简便计算成为过时话题等等.但计算器的一个基本特点是计算迅速准确,使用计算器,可以把学生从繁琐的数字计算中解脱出来,这样既减轻了学生的课业负担,又能
In our daily teaching, most of our teachers support the use of calculators by students. There are not many examples of how students can use calculators. They think that the use of calculators can have many negative effects. For example, the use of calculators can degenerate students' computing power and simplify their structures. Loss of ability, unary quadratic equation loses meaning, easy calculation becomes obsolete topic, etc. But one of the basic characteristics of calculators is that the calculation is quick and accurate. Using calculators, students can be freed from cumbersome numerical calculations. The burden of classwork, but also
