循序渐进的教学是培养学科核心素养的有效路径

Investigation of the Mathematical Abstraction Development of Junior Secondary School Students Based on Quality Monitoring

一般情况下，我们都是在两个层面上谈论核心素养问题的．一是一般意义的层面，二是学科意义的层面．本文讨论的话题主要是建立在数学学科意义层面上的，即基于学科意义下的数学素养的培养路径问题．

Mathematical abstraction is the basic component of the mathematics key competencies and a thinking process in which all the physical qualities of things are removed to get the research object of mathematics. After the test in 2016 on the quality of primary and secondary school education in Jiangsu, statistics and analysis are made of the score and the level distribution of the questions related to the mathematical abstraction, and the results show：（1） All the students have made a good performance overall in the development of mathematical abstract ability;（2） There are differences in the development of students＇ ability of mathematical abstraction;（3） There is no significant difference between boy and girl students in the development of mathematical abstract ability.
