计算器在美国小学数学教学中的使用及启示

Application and Implication of Calculators Used in Mathematics Teaching and Learning at the Elementary School Level in the United States

计算器在美国小学数学教学中的使用现状及其使用策略,对我国小学数学教学的启示是:作为工具的计算器可以在小学低年级开始使用,帮助学生进行认数、数数和强化位值的概念;教材中可以增加计算器功能的介绍,并在不同年级呈现适合孩子的内容;扩展计算器在解决问题、概念理解等方面的功能;重视教师在使用计算器教学方面的培训。

This paper analyzes the current situation of the calculators＇ application in the United States, and sums up about the effective use of a calculator for math learning strategy. We get some implication when comparing that with the use of the calculators in China. As a tool of calculator, learners can start to use in the early grade at elementary school to help them recognize numbers, count, and strengthen the concept of place value; We can introduce functions of calculator into the teaching materials for different grade children, extend functions of calculator in problem solving and conceptual understanding, and attach great importance to teachers＇ training teachers on the use of calculators.
