Core Documentation

Slides are used and provided (taken from the 2015-2016 course of Dr. Marica Biagini (INFN-LNF)

A text that deals, in more depth, with the topics of the program:

Type of delivery of the course

The program is organized into topics that are fully covered in a single lesson. The lesson is typically divided into two parts: - in the first part, the notions relating to the topic are provided, using the traditional blackboard (and more rarely the projection of slides); - in the second part a practical application is presented (exercise to be carried out, diagram to be analyzed, ..). Time is also left in the final phase of the lesson for insights raised by students' questions.

Type of evaluation

The final exam is oral; it is organized as an interview lasting about 20-30 minutes (depending on the student's preparation and his speed in dealing with the discussion). The interview is stimulated by two questions from the teacher; the student's answers can broaden the topic and direct the discussion.
