Teaching methods
The institutional course consists of classroom lessons,
the resolution
of numerical example relating to the issues addressed
and
discussions with students.
The lab course, in addition to lectures is made
of laboratory experiments, that must be carried out by students.
As concerns the teaching methods of this course unit, all students must attend Module 1, 2 online, while Module 3 on health and safety is to be attended in class. Information about Module 3 attendance schedule is available on the website of your degree programme
Assessment methods
The final examination aims to ascertain the level reached for the objectives listed under "learning outcome".
It consists in a written examination aimed to verify the knowledge acquired both in the courses of "fundamentals of polymer science" and "polymer science laboratory".
At least 75% of Laboratory course attendance is mandatory for sustaining the exam. The frequency will be assessed by the teacher. Laboratory work is done in groups and must be followed by the presentation of a report for each topic at least 15 days before the date of the examination.
Teaching tools
Videoprjection of the lessons is used in classroom.
The students are also able to obtain directly the above material
form Insegnamenti On Line
Students with DSA or disabilities can contact Servizio Studenti con Disabilità e DSA dell’Università di Bologna(http://www.studentidisabili.unibo.it/ [http://http/www.studentidisabili.unibo.it/], Italian only), the Department contact person (Prof. Giorgio Bencivenni, giorgio.bencivenni2@unibo.it [mailto:giorgio.bencivenni2@unibo.it] ) or directly the teacher to address the most convenient approach for accessing teaching materials and supports, and to gain access to all the convenient services and areas of the Departments (i.e. room for frontal lectures).
