The null hypothesis was confirmed, which means there were no significant
differences between the pre- and post-MCAI questionnaire for all third-year students (Table
1). Nevertheless, the means for pre- and post-MCAI show differences in scores. According to
an analysis of mean scores of each question on the MCAI, it was found that students did
most of the activities listed on the questionnaire, which indicates that they already had good
metacognitive skills. This cannot be analyzed as resulting from the lesson because there
were no significant differences. However, when responses were analyzed individually, there
were several students whose attitudes toward the statements changed after the lesson.
