摘　　要：以130名初三学生为被试,采用现场实验法,探讨了工作记忆和试题难度对学生几何应用题解决的影响。结果表明:工作记忆容量的主效应显著,容量高者成绩好;试题难度的主效应显著;工作记忆容量与试题难度之间的交互作用显著。130 students were selected from grade 3 of a junior high school as the participants of this research.Field experiments and clinical interviews were employed to examine the effects of working memory on geometric word-problem solving.The results indicated that the effects of working memory capacity and degrees of difficulty were all significant in geometric word-problem solving.The significant differences explained that the higher the capacity,the better the geometric word-problem solving performance;the lower the capacity,the worse the performance on the same problems.The effects of degrees of difficulty were significant in geometric word-problem solving.Working memory capacity and degree of difficulty had significant interaction in the geometric word-problem solving.
