In the first practical lesson, the first group constituted the experimental group and used the mobile device during the lesson. The second group formed the control group and received the same lesson following the classical teaching methodology (i.e., without the mobile application).
Afterwards, the groups interchanged their roles for the second practical lessons. That is, the first group of students became the control group and did not use the mobile application during the session. On the contrary, the second group had the opportunity to use the application.
A posttest questionnaire was used to assess the anatomical knowledge after each practical session. The first questionnaire was filled out immediately after the first session. It was composed of 8 multiple-choice questions. The minimum rating was 0 if all questions were wrong and 8 if all of them were correctly answered. The second questionnaire was filled out immediately after the second session and was also composed of 8 questions. The first 4 were open questions, whereas the remaining 4 were multiple-choice. In this questionnaire, the possible ratings also ranged from 0 to 8.
Data collected from the questionnaires were transferred to SPSS (version 19) for statistical analysis, and the results were presented using descriptive statistics. The mean value and standard deviation of the posttest scores were shown for each group and also the percentage of students who correctly answered each question were expressed in both examination tests. Differences in the distribution of the responses between groups were analyzed with the t-test after verifying the normal distribution of
the data with the Kolmogorov Smirnov test. The alpha level was considered significant at p < 0.05.
