Type of delivery of the course

Fontal lessons, exercises and tutoring. Frontal lessons are done at the blackboard. The teacher alternates theory to example and exercises to better understand the concepts. The teacher follows the textbook except for some parts for which notes are published on the course website. Exercises are done every week. Exercises are proposed and solved at the blackboard. The same exercise are published successively published with the solutions on the course website. Tutoring is done by two Ph.D. students that help students both proposing them exercises that they do together and both explaining to the students whatever exercise they might not have understood. The exercises proposed by the tutor are successively published on the webpage of the course. http://webusers.fis.uniroma3.it/~gallop/

Attendance

The presence at the lessons and exercises and tutoring is highly recommended but it is not compulsory so that all student have the chance to give the exam.

Type of evaluation

Written part and oral part separated. The student can pass the written part through the two partial written tests that are proposed during the course. The first partial is on the first half of the course and the second on the second half. Each partial consists in two exercises to be solved in two hours. The student can alternatively pass the written exams at the end of the course. Each one consisting in three exercised to be solved in three hours and that will span the whole program. A scientific calculator and a formulary can be used. Written exams and partial given in the past years are published on the web site of the course. During the oral exam the student will be asked to talk about two or three topics. Each topic has to be explained clearly and the formula that describe the phenomena of the topic have to be calculated on a sheet of paper. The level of understanding of the phenomena and the clarity in the explanation will be considered. If the COVID-19 emergency continues all the new rules for teaching and exams will be applied and in particular for the exams they will be online on teams and will be done as described above, both for the oral and for a written part.
