Changes in Students Assessment of Teaching Methods

When asked to rate group activities such as simulation exercises in the initial survey, students rated them as favorable methods for class instraction. The preference of simulation exercises averaged to a rating of 4.22 out of 5. However, the students assessment at the end of the course was even higher as the students expressed their satisfaetion with this method, raising its average rating to a 4.5. 

While the results shown in Table 6.1 assume that the data resemble a normal probability distribution, some may argue the credibility of this assumption. Hence, a nonparametric hypothesis testing method (the Wilcoxon signed-rank test) was employed to confirm the significance of the results, assuming the distribution of data is not necessarily normal. The results for the nonparametric test as shown in Table 6.2 confirm that the results are statistically significant to the 0.01 level.
