摘　　要：数感是初中阶段的十大关键能力之一,也是核心素养中审辨思维的重要表征形式.研究梳理了数感的内涵以及结构,并指出数感是在一定情境中处理数、数的运算以及数的评估的一种能力.通过对上海地区六年级学生的数感进行研究,发现六年级学生的数感发展水平在性别和成绩方面存在差异,六年级学生的数感发展水平受已有数学认知的影响,同时,六年级学生在评估和情境领域的数感表现受迷思概念的影响.教师在教学过程中要培养学习自信以减少差异,改善数相关知识的教学以及加强数的体验以减少迷思概念的产生.Number sense is one of the ten core competencies in junior high school as well as a representation form of critical thinking in core literacy.Prior research has sorted out the connotation and structure of number sense and pointed out that number sense refers to an ability to handle numbers,number operations,and number evaluation in certain situations.Through research on the number sense of sixth-grade students in Shanghai,it was found that there are differences in the number sense development levels of the sixth-grade students in terms of gender and performance.The level of the number sense development of the sixth-grade students was affected by existing mathematical cognition.The sixth-grade students’number sense performance in evaluation and situational domains was influenced by misconceptions.In the teaching process,teachers should improve the teaching of mathematics-related knowledge and strengthen the experience of mathematics to cultivate self-confidence in learning to reduce differences and misconceptions.
