研究结果表明，2、4、6 年级小学生口算时间随年级的增高而减少；在一位数加多位数不进位加法口算中，口算时间差异主要源于运算时间差异和整合时间差异；在一位数加多位数进位加法口算中，口算时间差异源于运算时间差异；在多位数减一位数不借位减法口算中，运算时间年级差异不显著，而整合时间存在显著的年级差异；在多位数减一位数借位减法口算中，口算时间的年级差异主要表现为运算时间的差异，而整合时间差异不显著。

In chapterⅡ, considering GLMMs data which the number of high units is different and the number of low units is small and unbalanced, we Conduct a series of simulations, the simulations show that regardless of the number of the level 2 units,the Bayesian estimate of random effects residual variance is more precise than PQL and the PQL estimation deviates from the true value seriously; In terms of the fixed effects estimates, When the number of level 2 units is 20, The mean and median of the Bayesian estimate is more precise than PQL,But With the number of level 2 units increase,the estimate of two methods is similar. Thus, in practical applications, we recommend the use of Bayesian method.
第二章针对不同高水平单位数，低水平数较小且不平衡的GLMMs数据，进行模拟研究，研究表明：无论水平2单位数的大小，贝叶斯方法随机效应残差方差估计值远比PQL法更接近真实值，PQL法严重偏离了真实值；而对固定效应参数估计值，当水平2单位数为20时，贝叶斯法各参数的均数和中位数均要较PQL法更接近真实值，而随着水平2单位数的增加，两种方法在估计固定效应参数时相差并不大，因而，在实际应用中，推荐采用贝叶斯法。
