摘要
研究目的旨在考察中学生空间图形的折叠、展开、旋转以及图形推理等能力的发 展特征和发展水平．研究结果表明：（1）总体而言，学生的空间图形心理表征能力随年级 （或年龄）的增长而提高；（2）不同的任务表征能力具有不完全一致的发展曲线．
In the present study, Chinese secondary students' mental development c haracteristic and level on spatial pattern folding, unfolding, revolving and rea soning were analyzed. The results showed: 1) In general, students' ability to re cognize spatial pattern develops with the rising of the grade (or the age); 2) E very spatial representation ability has the incompletely identical growing curve .
