Chapter 4. Perspective of the students - adaptivity
control group. Table 4.4 shows the means and standard deviations for adaptivity of the activities for improvement, resulting from the pre- and post-tests. Multilevel analyses revealed that neither the effect of time (F (1, 19.090) = 1.106, p = .306), nor the effect of group (F (1, 21.926) = .019, p = .893), nor the interaction (F (1, 19.090) = 2.852, p = .108) were significant. These results indicate that there was no effect of the intervention of the self- evaluation procedure on the students’ perception of adaptivity of the activities for improvement.

The experimental group was compared to the control group to investigate whether there were differences in the perceived adaptivity of the feedback between the two groups and whether there were differences between the pre- and post-tests. Table 4.5 shows the means and standard deviations for the adaptivity of the support, resulting from the pre- and post-tests. Multilevel analyses revealed that the effect of time (F (1, 1249.167) = 28,379, p <.001), and the interaction (F (1, 1249.167) = 10,005, p = .002) were significant. The effect of group (F (1, 22.841) = 2.416, p = .134) was not significant. In a post-hoc test, we found that only for the experimental group, was there a significant effect for time (p < .001), there was no effect for the control group (p = .096). These results indicate that the students in the experimental group perceived feedback aimed at improving their speaking skills as less adaptive in the period of the intervention (when the self-evaluation procedure was carried out) than before the intervention.
