Note: Not all significance tests are based on the same degrees of freedom.- - - - Finally, we calculated the predicted g+ that resulted after each step of WMR, with methodology entered first, pedagogy entered second, and media entered last. The statistics in Table11 are the equivalents of the predicted means in ANCOVA (i.e.... ..."

Table12 shows the individual study feature results for synchronous DE outcomes and Table 13 shows the same results for asynchronous DE outcomes. Shown are the original betas and standard errors along with the adjusted standard errors (see Equation 5), the adjusted confidence intervals (see Equation 6), and the adjusted z-tests (see Equation 7), evaluated with... ..."

This table reveals some interesting insights into the nature of these predictors, relative to one another.... In PAGE 21: ... This allows for an assessment of pedagogy and media, independently, after variation in methodology has been removed. Therefore, as shown in the second column in Table10 , these results derive from pedagogy and media. Table 12 shows the individual study feature results for synchronous DE outcomes and Table 13 shows the same results for asynchronous DE outcomes.... ..."

"... In PAGE 20: ... We did not enter methodology on the second step because this combination seemed to explain little of interest. Table9 shows the partitioning of variance between (QB) and within (QW) on the third step of regression for both synchronous and asynchronous DE outcomes. These statistics are applicable for all of the orders.... ..."
