The traditional setting was consisting of 3 sessions of
50 min of weekly theoretical lectures in front of overhead
presentation and 1 session of 50 min of weekly laboratory
experiences related to the contents taught in the theoretical
classes. All students had access to a virtual campus, where
classroom presentations and laboratory instructions were
available a week before class. Lectures were broken up
anytime during the class when students needed additional
explanations or to work on short in-class problems and
little small tasks. During the course, five different lessons
were taught, following the university official syllabus. At
the end of each lesson, students were given a take-home
problem set and were asked to complete an online quiz
questionnaire to help them to review the lesson. These
activities were not compulsory, but worth an additional
10 % in their grade.
