In order to address the first research question, the overall accuracy of all three combined targeted linguistic forms in each of the four test sessions (i.e., pre-test, immediate post-test, delayed post-test 1, and delayed post-test 2), regardless of the very different nature of the linguistic focus, were examined first. Table 1 in chapter 5 displays the descriptive statistics for overall accuracy rates over the four testing periods for the five treatment groups and the control group, and Figure 1 provides a visual representation of the decline in or improvement of accuracy for each group across the testing sessions.
