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".

Laboratory course attendance is mandatory for sustaining the exam.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).
