中小学生数学运算能力表现:结构要素、水平层次与评价指标

Operation Ability Performance:Element,Level and Assessment Index

运算能力是个体在处理数与数量关系过程中表现出来的一系列心理特征和行为特征,是数学学科能力的重要表现之一.运算能力由相关要素构成,在发展过程中体现出一定的水平差异性.为了改进中小学运算教学实践和优化运算教学评价,应细化运算能力的评价指标,尽量用学生外显的、具体的、可观察的运算行为表现来描述指标内容.

Operation ability is psychology and behavior characteristic during the period of dealing with number and relationship between numbers, is one of the important performance in mathematics abilities. Operational ability is made up of related factors and indicate some degrees of differences. To improve operation teaching practice and optimize operation teaching evaluation, operation ability evaluation indexes should be elaborated and the contents should be described in students’explicit ,concrete and observable performance.
