However, the academics took samples that represented much larger locations.
There were more significant differences in help-seeking behavior between conditions in the academic year sample population compared to those in the summer sample population.
Second, the time allotted to complete the Skill Builders in the summer sample was significantly longer (Mdn=13 weeks) than the academic year sample (Mdn=1.2 weeks), U 0), p<.0001.
Moreover, there were no differences in student attrition between conditions within each sample, but a chi-squared test showed that students in the academic year sample were significantly less likely to complete the Skill Builder (74% completion) compared to students in the summer sample (84% completion), X2 1, N = 679) = 9.17, p <.005.
Students from the summer sample population appeared to have more prior knowledge than students in the academic year sample.
As observed in Inventado et al. (2016) with the summer sample, there were no significant differences in attrition by condition in the academic year sample population.
The academic year sample of students were exposed to the same experimental methodology as the summer sample.
Students in the academic year sample population may have had less prior knowledge than students in the summer sample population, which led them to ask for more help to complete the Skill Builder.
First, all students in the summer sample were enrolled in suburban schools (N = 390) while students in the academic year sample were enrolled in suburban (N = 246), urban (N = 23), rural (N = 15), and an unidentified location (N = 31) schools, X2 3, N = 679) = 103.65, p <.0001.
Students in the summer sample were in either the ninth or the tenth grade while students in the academic year sample reported greater variation in grade levels, as presented in Table 7.
Third, although there were no differences in attrition between conditions for the individual studies, there were significantly more students in the academic year sample population who did not complete the Skill Builder compared to those in the summer sample population.
