of the data analysis and a brief summary of the main results is reported
in this section.
Pre/Post Learning Questionnaire
Statistical analysis computed on Pre/Post learning questionnaires results indicate that learning has actually occurred because of the tested difference between the pre and post conditions in all the three Case Studies. The paired T-test and the ANOVA computed showed that subjects have actually learned something about Kipling, English and also Statistics.
On the other hand, there is no significant difference among different experimental groups of subjects for Kipling and Statistics Case Studies. To conclude, subjects learned something but there is no significant difference between the conditions to learn with or without task / with or without examples.
Descriptive Statistics and Test of Normality
The indexes of the descriptive statistics computed for all the parameters and the Kolmogorov-Smirnov Test of Normality show that most of the variables have a not normal distribution. Because of that non parametrical analysis has been conducted in the further analysis.
