摘　　要：数位概念是儿童学习数学中的一个难点.我们采用了行为矫正法对一年级成绩不良的学生学习百以内进、退位加减法进行了初步的尝试研究。我们编制了20以内超十加减;百以内不进不退位加减;百以内进、退位加减三个有联系的模式试题,逐一对差生进行个别教学.通过试验,发现差生对百以内进退位的数位概念的掌握进步很大.The place value in addition andsubtraction is very difficult for child-ren to understand.The method of mo-dification was used for trial teaching ofslow learning pupil in acquiring thatconception.The content of place valuein addition and subtraction within 100was divided into 3 associated models.These models were taught one by one tothe pupils.Feedback and reward werealso given in the teaching process.Theexperiment proved successful in teach-ing the slow learning pupils to under-stand the place value.
