Note on textbook choice

The textbooks are obviously alternative, although in part complementary. The students must make the choice based on personal preferences and previous preparation. Resnick’s textbook is less formal and with a ”tutorial" style, with many exercises and examples; Focardi’s and Zotto’s textbooks are most formally accurate, with some examples and a few or nothing exercises; Mazzoldi’s textbook, while presenting examples and exercises, is rather synthetic though preserving a formal exactness.

## Teaching methods

The teaching methodology will be based primarily on frontal lecturing, with help of audio-visual multimedia instruments. The slides used to support lessons will be uploaded weekly on the Elly platform (Department of Mathematical, Physical and Computer Sciences: http://elly.smfi.unipr.it/2017/course/view.php?id=59). To download slides, you need to enrol in the online course.

The second part of the lesson will normally be devoted to the solution of problems and exercises, under the supervision of the teacher. A selection of exercises and problems for each topic will be uploaded weekly on the Elly platform.

## Assessment methods and criteria

Evaluation methods:

The assessment of the acquisition of learning outcomes will take place through mid-term exams in written form and a final exam in oral and (if necessary) written form. A provisional grade will be proposed to the students if the comprehensive grade of the mid-term exams is above a specific threshold (average grade equal to or higher than 18/30). In order to sustain the oral exam, which will aim to assign the final grade, students must enrol for it (registration to the oral exam on the ESSE3 web platform). The exemption from the written test examination and the assigned provisional grade will retain their validity for all the exams of the 2018/19 academic year (from June 2019 to February 2020).

If a student wishing to participate in the medium-term exams is unable to sustain one of them for demonstrable reasons (illness, work, or other impediments), he has the possibility to recover the lost exam during the oral exam, provided that: (1) he forewarned the teacher of the impossibility to participate in one of the medium-term examinations; (2) he has obtained an average evaluation of the remaining medium-term exams equal to or higher than 18/30.

The final exam, in written and oral form, is mandatory for the students having an insufficient grade of mid-term exams or do not giving the intermediate exams. In such a case, the students have to register to the written exam on the ESSE3 web platform and they will be considered eligible for the oral exam if they reach an assessment equal to or greater than 18/30.

During each of the written mid-term exams, the student will be asked to:

- demonstrate the knowledge and understanding of specific course topics, through open questions (typically 4-5), which will require the use of the technical correct jargon of Physics and synthesis skills (total weight 15 points);

- demonstrate the ability to apply knowledge and understanding by solving some problems (typically 2-3) related to specific course topics (total weight 15 points).

The written mid-term exams will be evaluated in 30-point scale. Each written exam will last 2.5 hours and will have to be done without the help of notes or books. The results of written exams will be notified by posting them on the ESSE3 web platform.

The written final exam will have a similar structure but problems and questions will cover all the topics of the course program and will last 3 hours.

During the oral exam, the student will be asked to:

- demonstrate the development of an autonomous judgment based on the knowledge and understanding of the fundamental laws of classical mechanics and of thermodynamics, by discussing the carried out written exams (final or mid-term) and deepening of theoretical arguments, drawing connections between the various parts and with basic concepts acquired in other courses;

- be able to use the correct technical-specialist language of Physics so that complex concepts can be translate correctly into an understandable language.

The oral exam will be evaluated in 30-point scale. The final grade will result from the arithmetic mean of the grades of written final exam (or the comprehensive grade of the mid-term written exams) and oral exam.
