When the questionnaire was handed out to the students, it was stressed that it was intended to improve learning activities for the subject and would not, under any circumstances, be marked, whether or not the answers were academically acceptable. As an incentive to complete the questionnaire, a small bonus was added to the mark simply for filling it out by the established deadline of about 3 days before the subject began. About one-fourth of the students filled it out in person (in about 20–30 min). Although they were encouraged to ask for explanations of the questions, none did. The rest of the students answered the questionnaire remotely by e-mail or through the Virtual Campus, requiring 20–45 min, according to their own reports.
