Teaching methods
The teaching activities include lessons carried out using multimedia presentations, videos and images (38 hours), and practice lessons (10 hours) carried out, if necessary, using software programs. During the lessons, frontal teaching alternates with moments of discussion with the students.
Additional teaching material used during the lessons is uploaded to the Elly web site of the course. The registration to the course is necessary to download the slides.
Students who are not attending to the course should periodically check the teaching material and the information provided by the professor on the Elly web site.
Assessment methods and criteria
The learning assessment is made with a written exam, normally with exercises and some questions on the topics developed during the lessons. The aim of the written exam, which has a duration of two hours, is to verify the student’s knowledge and the ability to apply the learned concepts to problems. The written exam, during which it is allowed the use of the calculator, is evaluated in the range 0/30. The honors are assigned only for perfect tests. The mark of the written exam is normally published within a week on the Esse3 web-site.
The online registration to the exam is mandatory and it is possible until one week before the exam date.
Further information about the examination procedure will be given to the students during the lessons and made available on the Elly web-site of the course.
