When looking at the same question based on students in the top and bottom of the class, Figure 5, there is, again, noticeable change. Students in the top half of the class start the implementation process with a positive attitude of 4.05 and complete the implementation at 3.47, a statistically significant effect, t(37) = 2.27, p = 0.03 . The drop among students in the bottom half of the sample is not statistically significant as their start value is 3.76, t(43) = 1.06, p = 0.30.
